Structural Galvanized Steel Coils High Tensile Strength Custom Size BS EN 10346
Structural Galvanized Steel Coils High Tensile Strength Custom Sizing BS EN 10346
Structural Galvanized Steel Coils are engineered for demanding construction and infrastructure projects, combining high tensile strength (up to 700 MPa) with BS EN 10346 compliance for unmatched load-bearing capacity and corrosion resistance. Featuring a hot-dip galvanized coating (Z275–Z450) and customizable thicknesses (0.5–8mm), these coils are ideal for structural frameworks, bridges, and industrial machinery. With widths up to 2,000mm and tailored cut-to-length services, they reduce fabrication waste by 20–30% while meeting global engineering standards.
Key Benefits:
- Superior Structural Integrity: Yield strength of 350–700 MPa for seismic-resistant and heavy-load applications.
- Custom Sizing: Thickness (0.5–8mm), width (600–2,000mm), and coil weight (5–25 tons) optimized for your project.
- BS EN 10346 Compliance: Certified for S320GD to S700MC grades, ensuring EU/UK market compatibility.
- Extended Lifespan: Z450 coating (450g/m²) provides 40+ years of corrosion protection in coastal/industrial zones.
- Sustainable Production: 85% recycled steel content, ISO 14001-certified, and REACH-compliant.
- Fast Processing: Laser-cut edges, pre-punched holes, or embossed surfaces available for quick assembly.
