DX52D Galvanized Pipe: High-Performance Corrosion-Resistant Steel for Multisector Applications.
Engineered for Longevity: Construction, Automotive & Industrial Systems
DX52D galvanized pipe is a cold-rolled steel pipe with a zinc coating (Z275 grade, 20–25 µm) offering 5–8x longer lifespan than non-galvanized alternatives. Ideal for harsh environments, its dual-phase microstructure ensures tensile strength up to 540 MPa while resisting corrosion in applications like roofing, automotive underbodies, and agricultural equipment.
Certifications & Key Advantages
- EN 10346 & ASTM A653 Certified: Compliant with JIS G3302 and GB/T 2518 standards.
- Cost Efficiency: 45% lower lifecycle costs vs. stainless steel (30-year service life).
- Custom Sizing: Thickness 0.1–300 mm (±0.15 mm), width up to 3 meters.
- MOQ 1 Ton: Available in hot-dip galvanized (HDG) or electroplated (EG) finishes.
