GP Sheets & Coils

GP Sheets and Coils are manufactured by coating cold rolled steel with a layer of zinc through a hot-dip galvanizing process. This coating protects the base steel from corrosion and enhances durability in outdoor and industrial environments.

These products are widely used in roofing, cladding, ducting, and fabrication applications due to their resistance to rust and environmental exposure. Their smooth surface, good formability, and coating uniformity make them suitable for both structural and aesthetic applications.

Sanjay Sales supplies a range of Galvanized Sheets and Coils that comply with Indian and international standards, ensuring reliable performance across various industries.
