It can be a simple L-shaped part, or it can be a mounting bracket with multiple bends.<\/p>\n<p class=\"isSelectedEnd\">Although a bracket may not look complicated, its manufacturing quality still depends on the sheet metal factory\u2019s production experience in <a href=\"https:\/\/ceshi.baoxuanmetal.com\/custom-sheet-metal-fabrication-for-global-oems\/\"><strong data-start=\"592\" data-end=\"626\">custom sheet metal fabrication<\/strong><\/a> and its quality control.<\/p>\n<p class=\"isSelectedEnd\">For engineers and purchasing teams, understanding the <strong>sheet metal bracket manufacturing process<\/strong> can help you reduce drawing revisions, quotation communication delays, and a series of related problems.<\/p>\n<p class=\"isSelectedEnd\">This article will explain in detail the full manufacturing process of <strong>custom sheet metal brackets<\/strong>, from engineering review to finished product delivery, and will also cover several aspects such as design and material selection.<\/p>\n<h2><strong>What Is a Sheet Metal Bracket?<\/strong><\/h2>\n<p class=\"isSelectedEnd\">A <strong>sheet metal bracket<\/strong> is a metal part made from flat sheet metal through cutting, bending, and forming, sometimes combined with welding or hardware assembly, to provide support or connection. It is generally used to mount panels, support frames, fix sensors, or connect different parts inside industrial equipment.<\/p>\n<p class=\"isSelectedEnd\">Compared with machined parts or cast parts, the advantages of <strong>sheet metal brackets<\/strong> are that they are lighter, easier to customize, and more suitable for mass production. A properly designed metal bracket can provide more reliable support with less material and a more stable manufacturing route.<\/p>\n<p class=\"isSelectedEnd\">Many custom brackets are produced according to 2D drawings, 3D CAD models, or a combination of both. However, it should be noted that details such as <strong>bend radius<\/strong>, <strong>flange length<\/strong>, <strong>hole-to-bend line distance<\/strong>, and tolerance notes may directly affect forming accuracy and final assembly fit.<\/p>\n<div id=\"attachment_4478\" style=\"width: 810px\" class=\"wp-caption aligncenter\"><img decoding=\"async\" aria-describedby=\"caption-attachment-4478\" class=\"wp-image-4478 size-fusion-800\" src=\"https:\/\/ceshi.baoxuanmetal.com\/wp-content\/uploads\/2026\/07\/sheet-metal-bracket-types-overview-800x533.webp\" alt=\"Various types of custom sheet metal brackets including L-shaped U-shaped and Z-shaped designs arranged on a workbench\" width=\"800\" height=\"533\" srcset=\"https:\/\/ceshi.baoxuanmetal.com\/wp-content\/uploads\/2026\/07\/sheet-metal-bracket-types-overview-200x133.webp 200w, https:\/\/ceshi.baoxuanmetal.com\/wp-content\/uploads\/2026\/07\/sheet-metal-bracket-types-overview-300x200.webp 300w, https:\/\/ceshi.baoxuanmetal.com\/wp-content\/uploads\/2026\/07\/sheet-metal-bracket-types-overview-400x267.webp 400w, https:\/\/ceshi.baoxuanmetal.com\/wp-content\/uploads\/2026\/07\/sheet-metal-bracket-types-overview-500x333.webp 500w, https:\/\/ceshi.baoxuanmetal.com\/wp-content\/uploads\/2026\/07\/sheet-metal-bracket-types-overview-600x400.webp 600w, https:\/\/ceshi.baoxuanmetal.com\/wp-content\/uploads\/2026\/07\/sheet-metal-bracket-types-overview-700x467.webp 700w, https:\/\/ceshi.baoxuanmetal.com\/wp-content\/uploads\/2026\/07\/sheet-metal-bracket-types-overview-768x512.webp 768w, https:\/\/ceshi.baoxuanmetal.com\/wp-content\/uploads\/2026\/07\/sheet-metal-bracket-types-overview-800x533.webp 800w, https:\/\/ceshi.baoxuanmetal.com\/wp-content\/uploads\/2026\/07\/sheet-metal-bracket-types-overview-1024x683.webp 1024w, https:\/\/ceshi.baoxuanmetal.com\/wp-content\/uploads\/2026\/07\/sheet-metal-bracket-types-overview-1200x800.webp 1200w, https:\/\/ceshi.baoxuanmetal.com\/wp-content\/uploads\/2026\/07\/sheet-metal-bracket-types-overview.webp 1536w\" sizes=\"(max-width: 800px) 100vw, 800px\" \/><p id=\"caption-attachment-4478\" class=\"wp-caption-text\"><span style=\"color: #808080;\">A range of custom sheet metal bracket types manufactured through laser cutting and press brake bending, suitable for mounting, supporting, and connecting industrial components.<\/span><\/p><\/div>\n<h2><strong>Why Is Sheet Metal Fabrication More Suitable for Manufacturing Brackets?<\/strong><\/h2>\n<p class=\"isSelectedEnd\">In fact, metal brackets are now basically manufactured by <strong>sheet metal fabrication<\/strong>, because it can support flexible structures, repeat production, and cost control.<\/p>\n<p class=\"isSelectedEnd\">A metal bracket can first be cut from flat metal sheet material into a flat blank, and then processed into the shape shown on the drawing by a CNC automatic bending machine or a manual bending machine.<\/p>\n<p class=\"isSelectedEnd\">The <strong>sheet metal fabrication process<\/strong> is suitable for both prototypes and orders that require mass production. Small quantities of prototypes can complete design verification through <strong>laser cutting<\/strong> and bending. For mass production, stable bending programs and fixtures can be used for production.<\/p>\n<p class=\"isSelectedEnd\">The most common reasons for choosing sheet metal fabrication to manufacture brackets are:<\/p>\n<ul data-spread=\"false\">\n<li><strong>Design flexibility:<\/strong> Holes, slots, tabs, openings, and flange structures can be integrated into the same part.<\/li>\n<li><strong>Good balance between strength and weight:<\/strong> Formed flanges and reinforcing structures can improve rigidity without using a solid block of metal.<\/li>\n<li><strong>Good production repeatability:<\/strong> CNC cutting and controlled bending help maintain dimensional consistency.<\/li>\n<li><strong>Easy assembly:<\/strong> Self-clinching nuts, studs, tapped holes, weld nuts, or other hardware can be completed before delivery.<\/li>\n<li><strong>Compatible with multiple surface treatments:<\/strong> Brackets can choose powder coating, electroplating, anodizing, brushing, or passivation according to the material and application.<\/li>\n<\/ul>\n<h2><strong>Sheet Metal Bracket Manufacturing Process<\/strong><\/h2>\n<p class=\"isSelectedEnd\">The manufacturing process of <strong>custom sheet metal brackets<\/strong> in a sheet metal fabrication factory includes drawing review, material selection, cutting, forming, secondary processing, surface treatment, inspection, and packaging. However, the specific process route still needs to be communicated and sampled between the demander and the supplier.<\/p>\n<h3><strong>1. Drawing Review and Manufacturability Check<\/strong><\/h3>\n<p class=\"isSelectedEnd\">Before production begins, the factory will review the drawings and CAD files to confirm whether the bracket part can be manufactured efficiently and accurately inside the factory. This step can help customers find problems such as unclear dimensions, bending difficulties, and hole position risks.<\/p>\n<div id=\"attachment_4473\" style=\"width: 810px\" class=\"wp-caption aligncenter\"><img decoding=\"async\" aria-describedby=\"caption-attachment-4473\" class=\"wp-image-4473 size-fusion-800\" src=\"https:\/\/ceshi.baoxuanmetal.com\/wp-content\/uploads\/2026\/07\/engineering-drawing-review-sheet-metal-bracket-800x533.webp\" alt=\"Engineering drawing of a sheet metal bracket with dimensional annotations and red-ink review notes on a desk with a digital caliper nearby\" width=\"800\" height=\"533\" srcset=\"https:\/\/ceshi.baoxuanmetal.com\/wp-content\/uploads\/2026\/07\/engineering-drawing-review-sheet-metal-bracket-200x133.webp 200w, https:\/\/ceshi.baoxuanmetal.com\/wp-content\/uploads\/2026\/07\/engineering-drawing-review-sheet-metal-bracket-300x200.webp 300w, https:\/\/ceshi.baoxuanmetal.com\/wp-content\/uploads\/2026\/07\/engineering-drawing-review-sheet-metal-bracket-400x267.webp 400w, https:\/\/ceshi.baoxuanmetal.com\/wp-content\/uploads\/2026\/07\/engineering-drawing-review-sheet-metal-bracket-500x333.webp 500w, https:\/\/ceshi.baoxuanmetal.com\/wp-content\/uploads\/2026\/07\/engineering-drawing-review-sheet-metal-bracket-600x400.webp 600w, https:\/\/ceshi.baoxuanmetal.com\/wp-content\/uploads\/2026\/07\/engineering-drawing-review-sheet-metal-bracket-700x467.webp 700w, https:\/\/ceshi.baoxuanmetal.com\/wp-content\/uploads\/2026\/07\/engineering-drawing-review-sheet-metal-bracket-768x512.webp 768w, https:\/\/ceshi.baoxuanmetal.com\/wp-content\/uploads\/2026\/07\/engineering-drawing-review-sheet-metal-bracket-800x533.webp 800w, https:\/\/ceshi.baoxuanmetal.com\/wp-content\/uploads\/2026\/07\/engineering-drawing-review-sheet-metal-bracket-1024x683.webp 1024w, https:\/\/ceshi.baoxuanmetal.com\/wp-content\/uploads\/2026\/07\/engineering-drawing-review-sheet-metal-bracket-1200x800.webp 1200w, https:\/\/ceshi.baoxuanmetal.com\/wp-content\/uploads\/2026\/07\/engineering-drawing-review-sheet-metal-bracket.webp 1536w\" sizes=\"(max-width: 800px) 100vw, 800px\" \/><p id=\"caption-attachment-4473\" class=\"wp-caption-text\"><span style=\"color: #808080;\">Before production begins, the engineering team reviews the bracket drawing for manufacturability, checking dimensions, bend sequences, hole positions, and tolerance notes to prevent production issues.<\/span><\/p><\/div>\n<h3><strong>2. Material and Sheet Thickness Selection<\/strong><\/h3>\n<p class=\"isSelectedEnd\">The material and sheet thickness will affect the strength, forming, surface, and other aspects of the product. Common <a href=\"https:\/\/ceshi.baoxuanmetal.com\/sr-mfg-metal-materials-library\/\"><strong data-start=\"1354\" data-end=\"1392\">sheet metal materials for brackets<\/strong><\/a> include cold-rolled steel, stainless steel, aluminum sheet, and galvanized steel sheet.<\/p>\n<p class=\"isSelectedEnd\">For many customers, the sheet thickness of custom sheet metal brackets is generally between 1.0 mm and 5.0 mm. However, the actual thickness depends on the customer\u2019s requirements. Thicker materials can indeed improve strength, but for processing, they may require a larger bend radius, higher forming force, and attention to springback.<\/p>\n<p>For small electronic equipment mounting brackets, thinner powder-coated steel sheets can be used.

If the hole is too close to the sheet edge, it may deform during cutting or tear during handling.<\/p>\n<p class=\"isSelectedEnd\"><strong>Hole-to-bend line distance:<\/strong> The distance between the hole and the bend line should be at least <strong>2t + R<\/strong> or more, where <strong>R<\/strong> is the inside bend radius. When the distance is insufficient, material flow during bending can cause the hole to deform or elongate. If the hole must be close to the bend line, the hole can be machined after bending through secondary processing, but this will increase cost.<\/p>\n<p class=\"isSelectedEnd\"><strong>Minimum bend radius:<\/strong> The inside bend radius should be set to at least 1 times the sheet thickness (<strong>1t<\/strong>) for mild steel, and 1.5 to 2 times the sheet thickness for stainless steel and aluminum. A smaller radius carries the risk of cracking on the outside surface of the bend, especially for aluminum alloys with lower ductility.<\/p>\n<p class=\"isSelectedEnd\"><strong>Minimum flange height:<\/strong> The shortest flange that will not slip out of the tooling is about 4 times the sheet thickness (<strong>4t<\/strong>). Shorter flanges require custom tooling or may not be formed cleanly.<\/p>\n<p class=\"isSelectedEnd\"><strong>Bend reliefs and corner notches:<\/strong> Small bend reliefs or notches should be added where the bend line meets a vertical edge to prevent material tearing during bending. Without bend reliefs, the material has nowhere to flow during bending, which may cause wrinkling or cracking.<\/p>\n<p>The table below summarizes the most common design rules:<\/p>\n<\/p>\n<div class=\"table-2\">\n<table width=\"100%\">\n<thead>\n<tr>\n<th align=\"left\">Design Parameter<\/th>\n<th align=\"left\">Minimum Reference Value<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td align=\"left\">Hole diameter<\/td>\n<td align=\"left\">\u2265 1t (laser cutting) or \u2265 material thickness<\/td>\n<\/tr>\n<tr>\n<td align=\"left\">Hole-to-edge distance<\/td>\n<td align=\"left\">\u2265 2t<\/td>\n<\/tr>\n<tr>\n<td align=\"left\">Hole-to-bend line distance<\/td>\n<td align=\"left\">\u2265 2t + R (inside bend radius)<\/td>\n<\/tr>\n<tr>\n<td align=\"left\">Inside bend radius (mild steel)<\/td>\n<td align=\"left\">\u2265 1t<\/td>\n<\/tr>\n<tr>\n<td align=\"left\">Inside bend radius (aluminum, stainless steel)<\/td>\n<td align=\"left\">\u2265 1.5\u20132t<\/td>\n<\/tr>\n<tr>\n<td align=\"left\">Minimum flange height<\/td>\n<td align=\"left\">\u2265 4t<\/td>\n<\/tr>\n<tr>\n<td align=\"left\">Slot width<\/td>\n<td align=\"left\">\u2265 1t<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<p>\n<h2><strong>Tolerances in Sheet Metal Bracket Fabrication<\/strong><\/h2>\n<p class=\"isSelectedEnd\">The dimensional tolerances of <strong>sheet metal fabrication<\/strong> are very different from those of CNC machining, because sheet metal processes involve shearing, thermal cutting, and plastic deformation, rather than removing material from a rigid workpiece.

Softer materials with greater springback, such as stainless steel and aluminum, are more difficult to control in bending dimensions than mild steel.<\/p>\n<p class=\"isSelectedEnd\"><strong>Material thickness<\/strong> affects both cutting accuracy and bending repeatability.<\/p>\n<p class=\"isSelectedEnd\"><strong>Process complexity<\/strong> also matters. The number of bends, the number of features near bend lines, and welding can all become sources of accumulated tolerance error.<\/p>\n<p class=\"isSelectedEnd\"><strong>Equipment condition and programming<\/strong> are also important. Well-maintained equipment will certainly perform better in terms of calibration and accuracy than heavily worn equipment.<\/p>\n<p class=\"isSelectedEnd\"><strong>Batch size affects tolerance consistency.<\/strong> The first article in production may be very accurate, but maintaining consistent accuracy across 5,000 parts requires regular inspection.<\/p>\n<p class=\"isSelectedEnd\">In fact, we have worked with many engineers who often face a very practical question: can they specify the tightest tolerances that the manufacturer or factory is capable of achieving?<\/p>\n<p class=\"isSelectedEnd\">In many cases, the answer is no.<\/p>\n<p class=\"isSelectedEnd\">This is because <strong>tight tolerances<\/strong> can lead to slower cutting speeds, more frequent tooling checks, additional inspection, and a higher scrap rate. All of these actions increase cost.<\/p>\n<p class=\"isSelectedEnd\">For the mounting holes of metal brackets, <strong>\u00b10.1 mm<\/strong> is generally enough to meet most application requirements. However, if you specify all features to <strong>\u00b10.05 mm<\/strong> accuracy, it will significantly increase cost and may also create multiple problems.<\/p>\n<p class=\"isSelectedEnd\">The best approach is to specify tight tolerances only for the few dimensions that truly drive assembly function, while marking the other features according to standard manufacturing capability.<\/p>\n<h2><strong>Choosing the Right Material and Surface Treatment<\/strong><\/h2>\n<p class=\"isSelectedEnd\">The material selection for metal brackets is not only a structural decision. It also determines how the <strong>sheet metal process<\/strong> performs. For example, choosing between mild steel and stainless steel does not only change the corrosion resistance of the finished product, but also changes the entire manufacturing process.<\/p>\n<p>The following two tables summarize the key material selection properties and <strong>surface treatments<\/strong> for brackets:<\/p>\n<\/p>\n<div class=\"table-2\">\n<table width=\"100%\">\n<thead>\n<tr>\n<th align=\"left\">Material<\/th>\n<th align=\"left\">Yield Strength<\/th>\n<th align=\"left\">Corrosion Resistance<\/th>\n<th align=\"left\">Formability<\/th>\n<th align=\"left\">Weldability<\/th>\n<th align=\"left\">Relative Cost<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td align=\"left\">Cold-rolled sheet \/ mild steel<\/td>\n<td align=\"left\">250\u2013350 MPa<\/td>\n<td align=\"left\">Low (without coating)<\/td>\n<td align=\"left\">Excellent<\/td>\n<td align=\"left\">Excellent (spot welding, MIG)<\/td>\n<td align=\"left\">Low<\/td>\n<\/tr>\n<tr>\n<td align=\"left\">Galvanized steel<\/td>\n<td align=\"left\">250\u2013350 MPa<\/td>\n<td align=\"left\">Good<\/td>\n<td align=\"left\">Good<\/td>\n<td align=\"left\">Medium (fume risk)<\/td>\n<td align=\"left\">Low\u2013medium<\/td>\n<\/tr>\n<tr>\n<td align=\"left\">SS304<\/td>\n<td align=\"left\">\u2265205 MPa<\/td>\n<td align=\"left\">High<\/td>\n<td align=\"left\">Medium (large springback)<\/td>\n<td align=\"left\">Good (TIG\/MIG)<\/td>\n<td align=\"left\">Medium\u2013high<\/td>\n<\/tr>\n<tr>\n<td align=\"left\">SS316<\/td>\n<td align=\"left\">\u2265205 MPa<\/td>\n<td align=\"left\">Very high<\/td>\n<td align=\"left\">Medium (large springback)<\/td>\n<td align=\"left\">Good (TIG\/MIG)<\/td>\n<td align=\"left\">High<\/td>\n<\/tr>\n<tr>\n<td align=\"left\">Aluminum 5052-H32<\/td>\n<td align=\"left\">~193 MPa<\/td>\n<td align=\"left\">Good<\/td>\n<td align=\"left\">Good<\/td>\n<td align=\"left\">Medium (TIG\/MIG only)<\/td>\n<td align=\"left\">Medium<\/td>\n<\/tr>\n<tr>\n<td align=\"left\">Aluminum 6061-T6<\/td>\n<td align=\"left\">~276 MPa<\/td>\n<td align=\"left\">Good<\/td>\n<td align=\"left\">Average (cracking risk)<\/td>\n<td align=\"left\">Average (TIG\/MIG)<\/td>\n<td align=\"left\">Medium<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<p>\n<p>&nbsp;<\/p>\n<\/p>\n<div class=\"table-2\">\n<table width=\"100%\">\n<thead>\n<tr>\n<th align=\"left\">Material<\/th>\n<th align=\"left\">Main Advantages<\/th>\n<th align=\"left\">Common Surface Treatments<\/th>\n<th align=\"left\">Typical Uses<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td align=\"left\">Cold-rolled steel<\/td>\n<td align=\"left\">Good strength, controllable cost, easy to form and weld<\/td>\n<td align=\"left\">Powder coating, zinc plating, painting<\/td>\n<td align=\"left\">Equipment brackets, frame supports, enclosure mounting parts<\/td>\n<\/tr>\n<tr>\n<td align=\"left\">Stainless steel<\/td>\n<td align=\"left\">Corrosion resistance, clean appearance, durable surface<\/td>\n<td align=\"left\">Brushing, passivation, polishing<\/td>\n<td align=\"left\">Food equipment, cleaning environments, medical-related components<\/td>\n<\/tr>\n<tr>\n<td align=\"left\">Aluminum sheet<\/td>\n<td align=\"left\">Lightweight, corrosion-resistant, good appearance after surface treatment<\/td>\n<td align=\"left\">Anodizing, brushing, powder coating<\/td>\n<td align=\"left\">Electronic equipment, instruments, lightweight structures<\/td>\n<\/tr>\n<tr>\n<td align=\"left\">Galvanized steel sheet<\/td>\n<td align=\"left\">Basic anti-corrosion ability, practical cost<\/td>\n<td align=\"left\">Light coating, simple processed surface<\/td>\n<td align=\"left\">General brackets, indoor and outdoor support parts<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<p>\n<p>&nbsp;<\/p>\n<h2><strong>Prototype and Mass Production: How Does the Manufacturing Strategy Change?<\/strong><\/h2>\n<p class=\"isSelectedEnd\">The same bracket design can use completely different manufacturing strategies depending on the order quantity.<\/p>\n<p class=\"isSelectedEnd\">For <strong>prototypes and small batches<\/strong> (1 to 50 pieces), the common method is: <strong>laser cutting<\/strong> flat blanks, manual setup on a standard press brake, and measuring key dimensions with calipers. No custom tooling is required. The lead time is generally 3 to 5 working days, mainly depending on complexity and the manufacturer\u2019s production schedule. The unit cost is higher because setup time is shared by only a very small number of parts, but the total cost is not high and the risk is the lowest. This stage is used to verify fit, function, and assembly results.<\/p>\n<p class=\"isSelectedEnd\">For <strong>small to medium batches<\/strong> (50 to 500 pieces), the process flow is similar, but it can benefit from optimized nesting, which arranges multiple parts on the sheet to reduce material waste, stored programmed bending sequences to ensure repeatability, and sampling-based inspection instead of 100% measurement. As setup time is spread across more parts, the unit cost decreases.<\/p>\n<p class=\"isSelectedEnd\">For <strong>mass production<\/strong> (more than 500 pieces), the economics change. Blanking dies can replace laser cutting and shorten the cycle time per part from seconds to sub-seconds. Dedicated bending tools can ensure angle consistency across the entire batch. Inspection can use gauges to improve speed, and <strong>statistical process control (SPC)<\/strong> can be used to monitor variation within production batches.

From laser cutting and CNC bending to welding, hardware pressing, surface treatment, and dimensional inspection, we can support the full process.<\/p>\n<p class=\"isSelectedEnd\">Before production begins, our engineering team conducts a <strong>manufacturability review<\/strong> for every drawing received, identifying potential issues such as hole-to-bend conflicts, overly tight tolerances, and missing specifications. This upfront review can prevent unexpected problems during production and help customers optimize their designs for both cost and quality.<\/p>\n<p class=\"isSelectedEnd\">We support bracket orders from single-piece prototypes to mass production of thousands of parts. The process selection is tailored according to your quantity and timeline.<\/p>\n<p>For more information or to request a quotation, please send your drawing files in <strong>STEP, IGES, DXF, or PDF format<\/strong>, together with the material, thickness, quantity, surface treatment, and delivery requirements to our engineering team.<\/p>\n<p>&nbsp;<\/p>\n<h2>FQAs<\/h2>\n<div class=\"accordian fusion-accordian\" style=\"--awb-border-size:1px;--awb-icon-size:16px;--awb-content-font-size:var(--awb-typography4-font-size);--awb-icon-alignment:left;--awb-hover-color:var(--awb-color2);--awb-border-color:var(--awb-color3);--awb-background-color:var(--awb-color1);--awb-divider-color:var(--awb-color3);--awb-divider-hover-color:var(--awb-color3);--awb-icon-color:var(--awb-color1);--awb-title-color:var(--awb-color8);--awb-content-color:var(--awb-color8);--awb-icon-box-color:var(--awb-color8);--awb-toggle-hover-accent-color:var(--awb-color5);--awb-title-font-family:var(--awb-typography1-font-family);--awb-title-font-weight:var(--awb-typography1-font-weight);--awb-title-font-style:var(--awb-typography1-font-style);--awb-title-font-size:16px;--awb-title-letter-spacing:var(--awb-typography1-letter-spacing);--awb-title-line-height:var(--awb-typography1-line-height);--awb-content-font-family:var(--awb-typography4-font-family);--awb-content-font-weight:var(--awb-typography4-font-weight);--awb-content-font-style:var(--awb-typography4-font-style);\"><div class=\"panel-group fusion-toggle-icon-boxed\" id=\"accordion-4468-1\"><div class=\"fusion-panel panel-default panel-8353a554c13c82cea fusion-toggle-has-divider\" style=\"--awb-title-color:var(--awb-color8);--awb-content-color:var(--awb-color8);\"><div class=\"panel-heading\"><h4 class=\"panel-title toggle\" id=\"toggle_8353a554c13c82cea\"><a aria-expanded=\"false\" aria-controls=\"8353a554c13c82cea\" role=\"button\" data-toggle=\"collapse\" data-parent=\"#accordion-4468-1\" data-target=\"#8353a554c13c82cea\" href=\"#8353a554c13c82cea\"><span class=\"fusion-toggle-icon-wrapper\" aria-hidden=\"true\"><i class=\"fa-fusion-box active-icon awb-icon-minus\" aria-hidden=\"true\"><\/i><i class=\"fa-fusion-box inactive-icon awb-icon-plus\" aria-hidden=\"true\"><\/i><\/span><span class=\"fusion-toggle-heading\">What Is the Minimum Bend Radius for Sheet Metal Brackets?<\/span><\/a><\/h4><\/div><div id=\"8353a554c13c82cea\" class=\"panel-collapse collapse \" aria-labelledby=\"toggle_8353a554c13c82cea\"><div class=\"panel-body toggle-content fusion-clearfix\"><\/p>\n<p>The minimum inside bend radius for mild steel is approximately equal to the material thickness (<strong>1t<\/strong>).
