CRCA, GP, GC, HRPO, PPGI

CRCA (Cold Rolled Close Annealed) Strips offer excellent surface finish, tight thickness tolerance and high formability, making them ideal for precision components and fabrication requirements. Their superior dimensional accuracy and smooth finish allow consistent performance in automotive parts, electrical panels, furniture, and general engineering applications.

Galvanised Steel in GP (Galvanized Plain) and GC (Galvanized Corrugated) forms provides long-lasting corrosion resistance due to a uniform zinc coating. GC sheets are widely used for roofing and cladding, while GP sheets and GPSP (Galvanized Plain Skin Pass) offer enhanced surface quality for applications like ducting, panels, enclosures, and consumer appliances. These products ensure durability in both indoor and outdoor environments.

HRPO Strips are produced by removing mill scale through acid pickling and applying protective oiling to prevent rust formation. This results in cleaner, scale-free steel suitable for fabrication, tube manufacturing, structural components, and heavy engineering. HRPO delivers better weldability and uniformity compared to standard hot rolled material, making it a preferred choice for industries requiring higher strength and clean surfaces.

PPGI (Pre-Painted Galvanized Iron) Coils and Sheets offer superior aesthetic appeal, excellent corrosion resistance, and long service life due to multi-layer paint coatings. They are widely used in architectural applications, pre-engineered buildings, and consumer products. Electro-Galvanized Steel (Zincro) provides an ultra-smooth zinc coating achieved through an electrolytic process, making it ideal for high-precision components, automotive parts, and electronics where uniform surface quality is critical.
