Cold Rolled Steel Products: Types, Uses, and Buying Guide
Cold rolled steel products are widely used in industries like automotive, construction, and manufacturing due to their superior surface finish, tight tolerances, and enhanced strength. This guide explores their types, features, and practical buying tips.
How to Find Reliable Cold Rolled Steel Products from China in 2025
China remains a top supplier of cold rolled steel products, offering competitive pricing and large-scale production capacity. To find reliable suppliers:
- Verify certifications like ISO 9001 and mill test reports.
- Check supplier reviews on platforms like Alibaba or Global Sources.
- Request samples to assess quality consistency.
- Negotiate MOQs and lead times upfront.
Top industrial hubs include Shanghai, Tianjin, and Guangdong.
What Buyers Should Know Before Buying Cold Rolled Steel Products from China
Key considerations include:
- Material grades: Common options are SPCC, DC01, or ASTM A1008.
- Thickness tolerance: Typically ±0.02mm for precision applications.
- Packaging: Waterproof wrapping prevents rust during transit.
- Payment terms: 30% deposit with balance before shipment is standard.
Types of Cold Rolled Steel Products

Cold Rolled Steel Products Q & A
Q: What's the price range per ton?
A: $600-$900/ton for standard grades, depending on thickness and order volume.
Q: How does cold rolling affect steel properties?
A: Increases strength by 20-30% but reduces ductility compared to hot rolled.
Q: What's the minimum order quantity from Chinese mills?
A: Typically 20-25 tons for standard grades, but traders may offer smaller quantities.
Q: How to prevent rust during海运?
A: Use VCI (volatile corrosion inhibitor) paper and desiccant packs in containers.
Q: What are alternatives to Chinese suppliers?
A: Consider Vietnam (5-10% cheaper) or India (comparable pricing but longer lead times).
