Why Bangladesh’s Roofing Market Needs Quality PPGI Coil
Colored corrugated roofing (“tin”/CI sheet) covers homes, shops, garment and textile factories, and rural buildings across Dhaka, Chattogram, Khulna and Sylhet. Demand is enormous and growing as buyers shift from bare GI to longer-lasting prepainted sheet. The climate is humid and monsoon-heavy, with cyclones and salty air along the Bay of Bengal coast — conditions that rust low-grade sheet quickly. A credible PPGI coil supplier for Bangladesh provides a reliable zinc base (Z40–Z120 for cost-sensitive, Z120+ for premium) under a UV-stable polyester topcoat. We supply economical thin gauges with consistent quality, plus heavier grades for factory and commercial roofing, to BSTI-aligned and ASTM/JIS specs.
