Prepainted Corrugated Roofing Sheet (PPGI / PPGL) – Trapezoidal & Wavy Profiles, 0.15-0.8mm Thick, Effective Widths up to 1025mm
Product Overview
Ready-to-install corrugated roofing and wall panels made from high-quality PPGI or PPGL coils. These sheets are roll-formed into structural profiles that greatly enhance the bending stiffness of thin steel sheets while keeping weight minimal. We produce both trapezoidal (ribbed) profiles for high-load roofing and sinusoidal (wavy) profiles for curved or aesthetic wall cladding. With effective coverage widths ranging from 608mm to 1025mm, these panels minimize overlaps and speed up construction. Choose from PE, SMP, or PVDF paint systems to match your required lifespan and budget.
Specification Spotlight: Effective Coverage Width
Our tooling supports 14 different effective widths to match local construction practices. The most popular exports are:
840mm (standard for lightweight roofing)
900mm (common in Southeast Asia & Africa)
1025mm (maximum coverage, reduces total panel count)

Core Advantages
Rapid Installation – Large effective width means fewer panels and faster labor.
Structural Strength – Trapezoidal ribs provide high load resistance for snow/wind loads.
Color-Matched Accessories – We can supply matching ridge caps, flashing, and screws (optional).
Flexible Connection – Available with lap joints, standing seams, or clip-lock systems.
Applications
Industrial buildings: Factory and warehouse roofing.
Agricultural: Poultry houses, pig shelters, crop storage sheds.
Residential: Carports, patio covers, prefabricated homes.
