Flat Steel

Hot Rolled Flat Steel is produced by rolling steel at high temperatures, creating coils, plates, and sheets with excellent weldability, structural strength, and versatile forming capability. With a broad dimensional range and robust mechanical properties, hot rolled steel is widely used in construction, automotive, machinery, fabrication, and general engineering applications where strength, durability, and cost efficiency are essential.

Pickled & Oiled Steel (P&O) offers clean, scale-free hot-rolled steel with enhanced surface quality and corrosion protection. Used widely in fabrication, stamping, automotive components, and structural applications, P&O steel provides excellent formability, weldability, and consistent mechanical performance. Supplied in coils, sheets, and plates, it serves as an efficient and cost-effective solution between hot-rolled and cold-rolled steel products.

Cold Rolled Flat Steel is produced by further processing hot rolled steel through precision cold reduction, yielding coils and sheets with highly accurate dimensions, smooth surfaces, and superior mechanical uniformity. Known for its excellent formability, tight thickness tolerances, and enhanced surface quality, cold rolled steel is widely used in automotive parts, home appliances, furniture, electrical enclosures, and high-precision fabrication applications.

Cold Rolled Black Annealed Steel is produced by cold reducing hot rolled steel to precise thickness tolerances and subsequently annealing it in a controlled atmosphere. The annealing process restores ductility lost during cold rolling and relieves internal stresses, resulting in steel with excellent workability.

The characteristic black surface appearance is formed during annealing in a controlled furnace environment and provides a uniform, clean finish suitable for further processing.

Hot-Dip Galvanized Steel (GI) is engineered to provide long-lasting corrosion protection, excellent durability, and reliable performance in outdoor and industrial environments. By coating steel with a layer of zinc through the hot-dip galvanizing process, GI steel offers superior resistance to rust and atmospheric corrosion—making it an ideal choice for construction, infrastructure, automotive, and general fabrication applications.

Galvanneal Steel (GA) combines the corrosion protection of galvanizing with enhanced paint adhesion and weldability. Produced by heat-treating hot-dip galvanized steel to form a zinc–iron alloy coating, galvanneal steel offers a matte, uniform surface that is ideal for painting, spot welding, and forming.

Aluzinc / Galvalume Steel (GL/AZ) offers exceptional corrosion resistance, heat reflectivity, and long-term durability through an aluminum–zinc alloy coating. Widely used in roofing, wall cladding, and construction panels, GL/AZ steel outperforms traditional galvanized steel in atmospheric environments. Supplied in coils and sheets, galvalume steel ensures reliable protection, energy efficiency, and extended service life for exterior and industrial applications.

Aluminized Steel (Al-Si) offers superior heat resistance, oxidation protection, and corrosion performance through a hot-dip aluminum-silicon alloy coating, typically around 90% aluminum and 10% silicon. The aluminum layer ensures excellent thermal and oxidation resistance, while silicon enhances coating adhesion and limits alloy layer growth during high-temperature exposure. Widely used in automotive exhaust systems, heat shields, furnaces, and industrial equipment, Al-Si steel delivers long service life, stable surface performance, and dependable durability in demanding thermal environments.

Zinc–Aluminum–Magnesium Steel (ZAM) represents the next generation of metallic-coated steel, engineered to deliver exceptional corrosion resistance, superior cut-edge protection, and long-term durability in the most demanding environments. By combining zinc with carefully controlled amounts of aluminum and magnesium, ZAM steel significantly outperforms conventional galvanized steel in terms of lifespan and protection efficiency.

Electro-Galvanized Steel (EG) is produced by applying a zinc coating to steel through an electrolytic plating process. This method creates a thin, uniform zinc layer with precise coating control and an exceptionally smooth surface finish. Unlike hot-dip galvanizing, electro-galvanizing does not involve molten zinc, resulting in superior surface appearance and tight dimensional accuracy.

Tin-Free Steel (TFS / ECCS) is a cold-rolled steel coated with a thin layer of metallic chromium and chromium oxide through an electrolytic process, providing excellent corrosion resistance, superior paint adhesion, and a clean, stable surface without the use of tin. As a high-performance alternative to traditional tinplate, TFS offers reliable surface uniformity and is widely used in packaging, containers, closures, and various industrial applications.
