Metal roofing sheets are durable structural panels engineered from cold-rolled steel, aluminum, or metal alloys. They're commonly profiled with ribs or corrugations to deliver superior water runoff, high tensile strength, and long-term weather protection.
Core Specifications & Features
Base Materials: Available in Galvalume (GL/PPGL) (aluminum-zinc alloy for maximum corrosion and heat resistance), Galvanized Iron (GI/PPGI) (zinc-coated mild steel), and standard mild steel (MS).
Standard Thickness: Typically ranges from 0.30 mm to 0.80 mm for standard structures, with 0.45 mm?0.50 mm being standard for residential sheds and light industrial sheds.
Profiles: Trapezoidal (box-ribbed) for wide purlin spans, classic wave corrugation, and architectural standing seam designs.
