Carbon Steel Sheet Metal Fabrication
Carbon steel sheet metal fabrication refers to manufacturing custom automotive components through laser cutting, CNC bending, and robotic welding. Strongd serves global clients, producing chassis parts, battery trays, brackets, and structural reinforcements. From prototype to mass production, we provide integrated solutions.
Advantages
Precision Forming
CNC-controlled processes ensure dimensional accuracy for safety-critical components：
Bending tolerance: ±0.1mm
Laser cutting accuracy: ±0.15mm
Flatness: ≤0.3mm/m²
01
High-Strength Output
Robotic welding delivers ≥90% base material strength (AWS D1.1 compliant), ideal for load-bearing parts like suspension mounts and EV battery enclosures.
02
Scalable Production
Automated laser cutting and stamping (2,000+ ton capacity) enable cost-efficient runs from 1-piece prototypes to 10,000+ volume orders.
03
Applications
Prototyping validates designs before mass production. For underbody components requiring corrosion resistance and structural integrity – such as motor mounts or cross-members – we combine SPCC/Q235 steel with zinc plating or e-coating. Learn more on our website.
04
Surface Treatment
Improper finishing compromises functionality. We offer:
Protective coatings: Zinc plating, e-coating (500+ hr salt spray resistance
Aesthetics: Powder coating (RAL/Pantone color matching)
Branding: Laser engraving, screen printing
05
