Premium grade galvanized slit coil manufactured by Authentic Steel. Features an advanced zinc coating layer (30-600g/m²) providing excellent structural durability and atmospheric corrosion resistance. Perfect for structural C/Z purlins, decking sheets, and infrastructure projects requiring high dimensional accuracy.
Authentic Steel, established as the professional export arm of Winroad Group in the prominent port city of Tianjin, introduces our industrial-grade galvanized slit coil engineered specifically for demanding structural fabrication and construction sectors. Backed by extensive manufacturing expertise since 1994, our factory utilizes world-class hot-dip processing lines that tightly bond a uniform zinc protective coating onto premium quality cold rolled or hot rolled steel substrates.
Our specialized automatic slitting machinery enables us to provide exceptional dimensional stability with precise width tolerances down to ±0.05mm. The zinc coating layer ranges flexibly from 30g/m² for indoor light applications up to a massive 600g/m² designed for severe atmospheric conditions and outdoor infrastructure engineering. This dense zinc coating acts as a dual-layer armor, offering barrier protection and sacrificial galvanic protection to prevent localized rusting at the slit edges.

Whether your factory produces industrial roof decking, heavy-duty C/Z purlins, scaffolding components, or highway guardrails, our galvanized slit coil provides the uniform mechanical properties and structural yield strength required for seamless cold-forming and stamping. Each finished bundle undergoes strict laboratory verification, evaluating tensile strength, elongation, bending capabilities, and exact zinc layer thickness to ensure full compliance with international standards including ASTM, EN, and JIS.
By working closely with domestic mill partners for heavy raw materials and directly fabricating the cold-rolled and galvanized narrow catalogs in our state-of-the-art workshop, we guarantee a continuous material supply and highly competitive direct factory pricing. Our logistics experts provide robust sea-freight packing, employing heavy-duty plastic inner wrappings, steel bands, and heavy wooden skids to completely protect your cargo against moisture during intercontinental shipments. We welcome global buyers, trading companies, and local distributors to establish long-term trade relations with Authentic Steel.
