Powder-Coated Carbon Steel Chassis
and OEM CRS / HRS Cabinets
CRS is commonly evaluated for thinner formed or cosmetic cabinet parts; pickled or descaled HRS may suit thicker structural members. The released drawing and RFQ define the actual grade, thickness, surface and coating. Review our custom sheet metal chassis and control cabinet manufacturing scopes.
- SPCC / DC01 / CRS thickness range by RFQ
- Finish-Ready Surface for Powder Coating and Paint
- Initial Response Target: 24 Working Hours
Built for control cabinets, rackmount chassis, machine brackets, cover plates and formed equipment panels.
Material Overview
Mild steel is low-carbon steel optimized for affordable fabrication, bending and welding. In sheet metal work, buyers often mean cold rolled steel such as SPCC, DC01 or CRS when they need a smooth, finish-ready surface for formed enclosures and brackets.
Choose this page when the part is thin-gauge, visible, powder-coated or dimensionally controlled. For thicker structural plate and mixed carbon steel grades, compare our carbon steel page and the carbon steel selection guide. For overlapping thin-sheet joints, review the spot-welding sheet stack and spacing guide before releasing weld locations.

Mild Steel & Cold Rolled Steel Grades
Common low-carbon sheet grades for enclosure panels, chassis, brackets and precision formed steel parts.
| Grade | Standard | Type | Tensile MPa | Yield MPa | Formability | Thickness Basis | Key Characteristics |
|---|---|---|---|---|---|---|---|
| SPCC | JIS G3141 | Cold rolled | 270-410 | 195+ | Good | Supplier / released specification | Cabinets, covers, panels and general CRS parts |
| DC01 | EN 10130 | Cold rolled | 270-410 | 140-280 | Very good | Supplier / released specification | European CRS equivalent for formed parts |
| DC03 / DC04 | EN 10130 | Drawing CRS | 270-370 | 120-240 | Excellent | Supplier / released specification | Deep-drawn covers and formed housings |
| CRS 1008 / 1010 | ASTM / SAE | Mild steel | 300-420 | 170-280 | Good | Supplier / released specification | North American low-carbon CRS equivalent |
| Pickled HRS | Commercial | Hot rolled pickled | 350-450 | 235+ | Moderate | Supplier / released specification | Heavier mild steel parts with cleaner finish than black HRS |
Where Cold Rolled Mild Steel Wins
Best fit when the design needs low cost, smooth finish and predictable forming before coating.
Mild Steel Processing Capability
Recommended Applications
- Control cabinets, rackmount chassis and covers
- Machine brackets, mounting plates and formed trays
- Powder-coated enclosures and appliance panels
- Low-cost fixtures, guards and internal supports
Design Notes
- Specify coating early because bare mild steel rusts
- Use CRS for smoother finish and tighter thickness control
- Use pickled hot-rolled steel for thicker low-cost parts
- Keep bend radii and grain direction consistent for formed panels
