Application Scenarios
Production Process
1. Material Selection：Cold-Drawn Customised Shaped Steel Strictly select high-quality steel (Q235, 45# steel, stainless steel, etc.).
2. Pre-Treatment：Remove oxide scale and oil to ensure clean surface.
3. Cold Drawing：Apply tensile force through cold drawing machine for mold forming.
4. Straightening：Use straightening machine to eliminate deformation and ensure straightness.
5. Surface Treatment：Pickling, galvanizing, polishing, etc., as required.
6. Inspection：Full inspection of dimensions, hardness, and mechanical properties; issue test reports.
7. Packaging：Rust-proof packaging + steel strapping to ensure safe transportation.
Quality Control
Testing Instrumentation: Spectroanalyzer, roughness gauge, universal tester for materials, metallurgical microscope.
Testing Parameters: Chemical constituents, dimensional precision, surface finish, mechanical characteristics, non-destructive evaluations (ultrasonic/radiographic inspection).
