What Is Sheet Metal Fabrication?
Sheet metal fabrication is a multi-step manufacturing process that transforms flat metal sheets into functional parts through techniques such as laser cutting, blanking, bending, stamping, welding, riveting, and surface finishing. These methods allow for the production of enclosures, brackets, panels, and other custom components with high dimensional accuracy.
This process is essential across industries like automotive, electronics, telecommunications, construction, and home appliances. Its versatility and scalability make sheet metal fabrication a core capability in modern industrial manufacturing, supporting everything from low-volume prototypes to high-volume production.

Customer Reviews
Our first order was a CNC-cut enclosure for an electrical cabinet. From CAD confirmation to finished sample, Chenying Hardware delivered in just 3 days. Everything was dimensionally accurate and powder-coated to spec—extremely efficient and professional.
Our parts had complex bends and tight hole locations. Chenying's engineers proactively suggested DFM changes that saved us from costly mistakes. The first prototype passed assembly perfectly. Outstanding technical support.
We've ordered over 10 batches of sheet metal housings. Chenying Hardware delivers on time with high consistency and quality. They are a dependable vendor for both prototype and production runs.
We submitted only 3D STEP files without flat layouts. Chenying's team created proper developments and flagged fitment issues early. Their in-house engineering capability is a big plus for design-stage collaboration.
Our aluminum enclosures needed sandblasting and anodizing with strict color tolerances. Chenying provided finish samples and adjusted perfectly to our target. The final result impressed both us and our end customer.
One delivery had minor surface marks. Chenying handled the issue immediately—replaced the units and took full ownership. They're not just a vendor, they're a responsible partner.
FAQs
What is sheet metal fabrication?
Sheet metal fabrication forms metal sheets into structural or functional parts through cutting, bending, welding, riveting, and finishing. It is widely used in electronics, equipment housings, and architectural applications.
Which processes are included?
- Laser cutting / CNC punching
- Bending and forming
- Welding and riveting
- Surface finishing (powder coating, plating)
- Assembly and functional testing
What sheet metal materials are commonly used?
SPCC steel, stainless steel 304/316, aluminum alloys 5052/6061, galvanized steel SECC, and copper. Selection depends on corrosion resistance, weight, and budget.
What sheet thickness range is supported?
We typically work with 0.5 mm – 6 mm. Consumer electronics favor thin gauges (0.5–2 mm) while industrial brackets use thicker sheets.
Laser cutting vs. CNC punching?
- Laser: Any shape, high precision, smooth edges.
- Punching: Fast for repetitive holes and simple geometry.
How to prevent cracking during bending?
Use ductile materials and proper inside radius. Avoid bending with grain direction. Heat treatment may be applied when necessary.
How do you ensure precision?
We use CNC-controlled equipment with strict jig design and tolerance compensation. Dimensional reports are provided for critical features.
What surface finishing options are available?
Powder coating, electroplating, anodizing, brushing, sandblasting, and hot-dip galvanizing. Each affects durability and appearance.
Can you support low-volume customization?
Yes. Sheet metal fabrication is perfect for prototyping and low-volume production thanks to flexible setups and short changeover times.
What affects sheet metal pricing?
Material cost, part complexity, finishing, tolerance requirements, and schedule pressure are the main contributors.
Typical production lead time?
- Prototypes: 2–5 days
- Small batches: 5–10 days
- Larger/complex: 10+ days
Is sheet metal fabrication environmentally friendly?
Yes. Automated lines reduce dust and noise. Waste materials are recycled. We comply with environmental standards.
How to increase part strength?
Add ribs or flanges, improve joint design, or use higher-strength alloys and structural bends to increase rigidity.
What should CAD drawings include?
Clear bend lines, angles, tolerances, and unfolded views. Avoiding locked corners ensures manufacturability and accurate assembly.
How to verify supplier capability?
Look at machining range, finishing capacity, certifications, case studies, and inspection equipment such as CMM.
What inspections are required before shipping?
Dimensional measurement, weld check, finish adhesion, hole fit tests, and load or corrosion tests for high-reliability products.
