Galvalume steel strip is a steel strip coated with an aluminum-zinc alloy layer. It is also called Aluzinc steel strip, AZ coated steel strip or Al-Zn coated steel strip.
The aluminum in the coating helps improve heat reflectivity and surface durability, while the zinc provides sacrificial protection to the steel substrate. The silicon helps improve coating adhesion and stability during processing.
Because of this coating structure, Galvalume steel strip is widely used for products requiring better corrosion resistance, heat reflection and outdoor durability than ordinary black steel strip or standard galvanized strip.
Slit Galvalume steel strip is produced by slitting wider Galvalume steel coils into narrow widths. It is suitable for customers who need accurate strip width, stable coil feeding and continuous production performance.
Galvalume steel strip can be used as cable armoring material to provide mechanical protection and corrosion resistance. It is suitable for power cables, communication cables and industrial cable systems.
Galvalume steel strip is widely used in roll forming production lines. It can be processed into light steel profiles, roofing accessories, channels, brackets, edge trims and construction components.
Because of its heat reflectivity and corrosion resistance, Galvalume steel strip is suitable for ridge caps, flashing, roof trims, gutters, drainage parts and other roofing accessories.
Customized Aluzinc strips can be supplied according to required thickness, width, AZ coating, grade, hardness, edge condition, surface treatment, coil ID, coil weight and packing method.
Galvalume steel strip is widely used as a raw material for construction and industrial processing.
In cable manufacturing, it is used for cable armoring to improve mechanical strength and corrosion protection. In roll forming, it can be processed into light steel profiles, channels, support strips, brackets, roofing trims and building accessories.
For roofing and construction material production, Galvalume steel strip is used for flashing, ridge caps, gutters, rainwater systems, roof edge parts, wall accessories and prefabricated building components.
It is also suitable for ducts, hardware parts, stamping products, metal edging, packaging strips, agricultural equipment, appliance parts and general fabrication products requiring corrosion-resistant steel material.
The aluminum-zinc alloy coating provides strong protection against rust, oxidation and atmospheric corrosion, making Galvalume steel strip suitable for outdoor and construction applications.
The Al-Zn coating reflects heat better than ordinary zinc coating, making it useful for roofing accessories and building materials used in hot climates.
Galvalume steel strip can be slit, cut, stamped, bent, roll-formed and processed into many finished products.
Different AZ coating weights can be selected according to service life requirement, application environment and project budget.
The metallic spangle surface gives Galvalume steel strip a clean and professional appearance, suitable for both industrial and construction products.
Thickness, width, AZ coating, hardness, edge type, coil ID, coil weight and packing can be customized according to customer production line requirements.
Galvanized steel strip is coated mainly with zinc. It provides good corrosion resistance and is widely used for pipe making, stamping, hardware and general construction applications.
Galvalume steel strip is coated with an aluminum-zinc alloy layer. It usually provides better long-term corrosion resistance and stronger heat reflectivity, especially for roofing accessories, outdoor construction materials and hot climate applications.
For general anti-rust use, galvanized strip is cost-effective. For better outdoor durability and heat reflection, Galvalume steel strip is often a better choice.
Henan GDD can supply Galvalume steel strips with different surface treatments, including chromated, passivated, oiled, dry and anti-fingerprint surfaces. Surface treatment can be selected according to storage time, processing method, corrosion requirement and final application.
Edge options include slit edge, mill edge, round edge and customized edge processing. For automatic roll forming or cable armoring production lines, stable width tolerance and smooth edge quality are important for reducing production problems.
