Sterling Steels Co is an industry-leading supplier and custom processor of high-grade GP (Galvanized Plain) Slit Coils. We cater to complex manufacturing requirements across India by providing precision-slit steel strips processed from premium tier-1 master coils.
Leveraging state-of-the-art slitting machinery in our Taloja MIDC service center, we maintain ultra-narrow tolerances, uniform edge profiling, and clean, burr-free slits. Whether your engineering lines require specific zinc coating masses like Z120 or Z180 , or precise structural grades according to Indian and international standards (such as IS 277 , ASTM A653 , or JIS G3302 ), our team delivers components tailored natively to optimize your high-speed roll forming and processing production setups.
A GP (Galvanized Plain) Slit Coil is engineered by taking a full-width master galvanized steel coil and feeding it through advanced rotary slitting knives to slice it longitudinally into several narrower strips (or ribbons). The source raw material undergoes a hot-dip galvanizing line process where zinc forms an iron-zinc alloy metallurgical bond over the steel surface, ensuring deep corrosion mitigation even if edges are cut or subjected to physical handling.
At Sterling Steels Co, we guarantee high dimensional consistency and smooth rewinding profiles across every narrow ribbon. Our industrial slit ribbons ensure effortless integration into automated lines such as robotic tube mills, mechanical stamping presses, and continuous cold roll forming mills.
