Skin-pass processed galvanised sheets with 120 g/m² zinc coating. Better surface quality than standard GP 120 GSM — ideal for painted finishes, automotive parts, and precision fabrication.
Get Live Price →GPSP 120 GSM combines the corrosion protection of Z120 zinc coating with the enhanced surface quality of skin-pass rolling. The result is a sheet that's smoother, flatter, and better suited for visible or painted applications compared to standard GP 120 GSM.

For standard roofing or ducting where surface finish isn't critical, regular GP 120 GSM is more cost-effective.
GPSP typically costs ₹3,000–5,000/MT more than equivalent GP due to the additional skin-pass processing. The exact premium depends on thickness, width, and maker.
While it can be used, it's over-engineered for basic roofing. The price premium isn't justified unless the roof will be painted or has aesthetic requirements. Standard GP Z120 is recommended for roofing.
