Hot-Dipped Aluminum Steel Coil 1.0-4.0mm Thickness Marine Grade BS EN 10326
Hot-Dipped Aluminum Steel Coil is a premium marine-grade material engineered to withstand corrosive saltwater environments while delivering unmatched structural integrity. Certified to BS EN 10326 and ISO 1461 standards, this coil features a 55% aluminum-zinc alloy coating applied via hot-dip galvanization, ensuring long-term protection against rust, UV exposure, and extreme weather. Available in 1.0–4.0mm thicknesses and widths up to 2,000mm, it is the go-to choice for shipbuilders, offshore platforms, and coastal infrastructure projects.
Key Selling Points:
- Marine-Grade Corrosion Resistance: Outperforms traditional galvanized steel by 4x in salt spray tests (ISO 9227).
- High-Temperature Durability: Withstands up to 315°C without coating degradation (EN 10326 compliant).
- Lightweight & Strong: Tensile strength up to 550 MPa (Grade S355GD), reducing vessel weight and fuel costs.
- Eco-Friendly: 100% recyclable and compliant with REACH, RoHS, and green shipbuilding standards.
- Custom Sizing: Precision slitting and cutting for seamless integration into marine designs.
