What is Color Coated Corrugated Board?
Color coated corrugated board, also known as color steel tile or PPGI roofing sheet, is a lightweight, high-strength building material manufactured from prepainted galvanized or galvalume steel, then roll-formed into corrugated profiles.
The combination of high-quality base steel, advanced color coating technology, and precision corrugated design delivers exceptional performance:
Corrosion Protection: Zinc or Al-Zn coating prevents rust
Weather Resistance: PVDF/HDP coating resists UV fading
Structural Strength: Corrugated design enhances load-bearing capacity
Water Drainage: Ribbed profile ensures efficient water flow
Aesthetic Appeal: Available in wide range of RAL colors
Ideal for roofing, wall cladding, and various construction applications.
