The facing sheet on a sandwich panel does more than look finished — it determines how well the panel resists weather, corrosion and physical damage over its service life.
PPGI (pre-painted galvanized iron) combines a zinc coating for corrosion resistance with a painted top layer for UV and weather protection.
Our standard 0.45mm gauge is chosen to balance panel weight, rigidity and cost for most roofing and wall cladding applications in Pakistan's climate.
Projects with unusual exposure conditions or specific colour requirements can request alternate PPGI gauges and coatings..
