DX53D+Z is a high-quality steel coil treated by hot-dip galvanizing (HDG). The base material is DX53D low-carbon steel, and the zinc layer coverage ranges from Z60 (low zinc layer) to Z450 (ultra-high zinc layer). This product has both excellent formability and long-term anti-corrosion performance, and is widely used in automobiles, home appliances, construction, energy and other fields.

 

Hot-dip galvanizing (HDG) is an anti-corrosion technology that immerses steel parts in molten zinc liquid (about 450°C) to form a zinc-iron alloy layer through metallurgical reaction. It is characterized by a thick zinc layer (usually 45-300μm) and an anti-corrosion life of up to 20-50 years; metallurgical bonding, high bonding strength between the coating and the substrate, and not easy to peel off; full coverage, which can protect the corners of complex-shaped workpieces.

We have a large inventory of steel coil available in a variety of thicknesses and widths, and can customize them to meet specific project requirements.GNEE STEEL is committed to excellence and customer satisfaction, ensuring that our products exceed your expectations in quality and performance.
Gnee can provide the following services:
Coating Thickness: Measurement of the thickness of the zinc coating on the galvanized steel surface. This is crucial for ensuring that the steel has an adequate protective layer.
Dimensions: Checking and documenting the dimensions of the galvanized steel, including length, width, and thickness of the steel itself.
Weight: Determining the weight of the galvanized steel, which may include both the steel and the zinc coating.
Corrosion Resistance Testing: Assessing the corrosion resistance of the galvanized steel, which is a key property of the zinc coating.
