Corrugated Roofing Sheet Material (Optional)
Galvanized Steel (GI)
Zinc-coated steel via hot-dip or electro-galvanizing. Delivers good corrosion resistance, solid structural strength, and cost efficiency, widely used for industrial, residential, and agricultural roofing projects.
Galvalume Steel (GL)
Steel sheets coated with ~55 % aluminum, ~43 % zinc alloy. Offers superior corrosion resistance, heat reflectivity, and long service life. Ideal for coastal zones and high-temperature roofing environments.
PPGI Roofing Sheets
Zinc-coated steel pre-painted with PE, SMP or PVDF layers. Combines aesthetic variety with corrosion and weather resistance. Common in construction facades, appliance panels, and general roofing.
PPGL Roofing Sheets
Al‑Zn alloy substrate with painted PE/SMP/PVDF finish. Delivers enhanced durability, UV resistance, and color retention in harsh conditions. Frequently chosen for architectural roofing and cladding.
