profiled steel sheet

Introduction to Profiled Steel Sheet

Profiled steel sheet, often referred to as metal roofing or siding, is a versatile building material manufactured from cold-formed steel coils. The sheets are passed through a series of rollers to create a specific wave, trapezoidal, or ribbed pattern, which significantly increases the panel’s structural rigidity and load-bearing capacity compared to flat steel. This product is widely used in industrial, commercial, and agricultural construction for roofing, cladding, and decking applications. The base material is typically galvanized steel (GI), Galvalume (Aluzinc), or pre-painted (PPGI) steel, offering excellent corrosion resistance and aesthetic flexibility. Profiled steel sheets are lightweight, durable, fire-resistant, and easy to install, making them a cost-effective alternative to traditional materials like concrete, clay tiles, or asphalt shingles.
