Hot-dip Galvanized Steel Coil/Sheet/Strip

Hot-dip Galvanized Steel Coil/Sheet/Strip (GI Steel) is a core anti-corrosion product launched by Wongsteel (Beijing Yijing Technology) for the sheet sector. A dense zinc layer is formed on the steel surface through hot-dip galvanizing process, achieving excellent comprehensive protection performance. It is widely used in construction, home appliances, automotive, metallurgy and other industries, especially suitable for roofing, doors and windows, shutter doors, ceiling keels and other scenarios.

The product strictly follows international standards such as JIS G3302, ASTM A653M and EN 10346, with comprehensive specifications: thickness 0.17-3mm, coil width 800mm-1250mm, steel coil inner diameter φ508mm-φ610mm, maximum coil weight 3-10MT; zinc coating thickness 30-270g/㎡, can provide regular spangle and zero spangle surface forms, and supports surface treatments such as chromated, oiled and skin passed, meeting the anti-corrosion and processing needs of different working conditions.

It has excellent mechanical properties: yield strength ≥245MPa, tensile strength ≥340MPa, elongation ≥20%, with good stamping, bending, welding and other forming properties, adapting to complex component processing; precision control is strict, thickness tolerance ±0.01mm, width tolerance 0/+5mm, high dimensional stability, ensuring the consistency of subsequent processing.

Relying on the cathodic protection of the zinc layer, hot-dip galvanized steel greatly improves the corrosion resistance and service life of steel. Compared with ordinary steel, it can effectively reduce later maintenance costs, and is the preferred anti-corrosion sheet for building envelopes, home appliance shells, automotive bodies and other fields. Wongsteel (Beijing Yijing Technology) can provide customized products and processing services according to customers' application scenarios, zinc layer requirements and specifications, as well as complete quality inspection and after-sales guarantee, helping customers in various industries obtain high-quality galvanized sheets.
