What is a GP Sheet? Structural & Fabrication Overview
A GP (Galvanized Plain) Sheet is a premium flat steel product manufactured by processing a hot-dipped galvanized steel coil through precision decoiling, corrective leveling, and shearing machinery to obtain flat, straight sheets cut to required lengths. The protective zinc layer acts as a sacrificial barrier, keeping structural integrity safe from oxidation.
At Sterling Steels Co, our GP sheets are engineered to deliver:
- Excellent Corrosion Resistance: Superior protection provided by uniform zinc coating (GSM parameters).
- Exceptional Flatness: Advanced corrective leveling removes coil set and internal manufacturing stresses.
- Strict Dimensional Accuracy: Clean, square-cut sheared edges with minimal diagonal variations.
- Superior Formability: High-grade base steel suitable for bending, lock-seaming, and deep-drawing.
