DX53D aluminium-zinc coated steel coil utilises low-carbon steel as its base material. Compared to grades such as DX51D, it typically exhibits higher yield strength and superior durability. Its yield strength generally ranges between 270–300 MPa, tensile strength between 350–450 MPa, and elongation after fracture is no less than 24%. This enables it to withstand greater deformation during processing without fracturing, demonstrating excellent formability.

Due to zinc's inherent properties, this product exhibits outstanding corrosion resistance, paintability, and workability. The manufacturing processes and specifications for hot-dip galvanised steel sheets and galvanised steel coils are generally consistent. Hot-dip galvanising is a process that prevents rusting by forming a protective zinc layer on the surface of steel or iron plates. * Possesses outstanding corrosion resistance, paintability, and workability owing to zinc's self-sacrificing properties. * Allows selection and production of required zinc coating weights, particularly enabling the formation of thick zinc layers (up to 275 grams per square metre). * Classified into two types based on whether skin-pass rolling is performed: non-grained and ultra-smooth.

As the surface coating of AZ50 galvalume steel coil is an alloy composed of aluminum, zinc and other trace elements, it has outstanding corrosion resistance and gradually replaces galvanized coil. The mixed structure of hot dip aluminum zinc silicon coating has its unique advantages in corrosion resistance. AZ50 aluminized zinc is a high quality corrosion resistant steel. It is made of a combination of aluminum and zinc, with an aluminum content of at least 50%. AZ50 aluminized zinc is not only suitable for the exterior of your house, but also for structural purposes and industrial applications. This alloy has many advantages, including excellent strength, impact resistance and excellent weldability.

The coating on S220GD Galvalume Steel Coil is typically aluminium-zinc (Galvalume), generally comprising 55% aluminium, 43.5% zinc, and 1.5% silicon. This coating endows the steel coil with outstanding atmospheric corrosion resistance, offering 2-4 times the durability of galvanised steel sheets. It also possesses excellent heat resistance, capable of withstanding elevated temperatures.

DX52D is a flat steel product for cold forming, with a base material of low-carbon steel. The yield strength of this steel coil does not exceed 260 MPa, its tensile strength ranges between 300 and 360 MPa, and its elongation after fracture is no less than 28%. This endows it with favourable ductility and stamping properties, enabling it to withstand a degree of plastic deformation without fracturing.

Also known as galvalume or zincalume steel, aluzinc steel is a form of cold-rolled galvanized steel with a metal coating composed of 55% aluminum, 43% zinc, and 1.6% silicon. Its unique composition gives aluzinc steel some distinctive features by the combination of the physical protection and high durability of aluminum and the electrochemical protection of zinc.
