Galvanised Plain Skin Pass — the premium alternative to standard GP. Superior surface finish, tighter flatness tolerances, and excellent formability for demanding applications.
Configure & Get Price →GPSP stands for Galvanised Plain Skin Pass. It is a premium variant of GP sheet where the galvanised coil undergoes an additional skin-pass rolling operation after hot-dip zinc coating.
The skin-pass process applies a light cold-reduction (typically 0.5–2%) which:

| Paintability | Good | Superior |
| Standard | IS 277:2008 | IS 14358:1996 |
| Price Premium | Base | ₹3,000–5,000/MT more |

GPSP undergoes an additional skin-pass rolling after galvanising, which improves surface quality, flatness, and formability. It's ideal for applications where the surface will be painted or where the part is deep-drawn.
Yes, GPSP carries a premium of ₹3,000–5,000/MT over equivalent GP sheets due to the additional processing step.
