South American manufacturers face chronic corrosion in tropical climates, costly material waste from imprecise cuts, and unreliable surface quality for high-end exports. In Brazil’s automotive sector, humidity-induced rust on conventional steel parts caused a 22% rejection rate in 2023.
Cold Rolled Steel Sheets solve regional challenges with three core strengths:
Superior corrosion resistance – Zinc-coated surfaces (120–275g/m²) withstand coastal humidity, reducing rust-related losses by 40%.
Tighter dimensional accuracy – ±0.03mm thickness tolerance eliminates rework for Chilean machinery exporters.
Customizable formats – Coil-to-cut services help Argentinian builders minimize scrap by 18%.
Property | Cold Rolled Steel Sheet (JIS G3141) | Hot Rolled Steel (Regional Average) |
---|---|---|
Surface Roughness (Ra) | 0.4–1.0µm | 3.5–6.5µm |
Yield Strength | 340–550 MPa | 220–380 MPa |
Thickness Tolerance | ±0.03mm | ±0.18mm |

Case 1: Colombian Appliance Maker
Issue: Washing machine panels required 3-stage polishing due to surface pits.
Solution: Switched to SPCC Cold Rolled Steel Sheets (1.5mm thickness).
Result: Direct-paint readiness achieved, saving $9,800/month in finishing costs.
Case 2: Peruvian Solar Farm Contractor
Issue: Brackets corroded within 2 years in coastal projects.
Solution: Adopted ZAM-coated sheets (150g/m² coating weight).
Result: Passed 2,000-hour salt spray tests, securing 10-year maintenance contracts.
Q: How to prevent rust during maritime shipping to South America?
→ Use VCI (Vapor Corrosion Inhibitor) packaging + moisture-proof wrapping, proven effective in Brazilian ports.
Q: Can cold rolled sheets replace stainless steel for food processing equipment?
→ Yes. Electro-galvanized sheets (EG 60g/m²) cut material costs by 30% for Uruguayan dairy plants.
Q: What’s the minimum order quantity (MOQ) for trial orders?
→ 2-ton trial batches available, with Chile/Argentina warehouse stock for urgent needs.
