Galvalume steel, also known as zincalume or aluzinc steel, is a cold-rolled galvanized steel with a specialized metal coating composed of 55% aluminum, 43% zinc, and 1.6% silicon. This unique composition combines the physical protection and high durability of aluminum with the electrochemical protection of zinc, resulting in superior corrosion resistance and longevity.
As the world's fastest-growing metallic coating, Galvalume steel offers an optimal combination of strength, formability, and recyclability. The steel substrate provides structural integrity while the Al-Zn alloy coating delivers proven long-term anti-corrosion performance, creating an economical product with excellent eco-friendly attributes including durability, recyclability, energy efficiency, and efficient resource utilization.
Superior corrosion resistance with increased Al and Mg content providing several times better protection than standard galvanized steel
Low friction coefficient and stable friction characteristics for improved punching performance and reduced coating wear
Excellent welding performance with reduced spatter during laser welding processes
Zinc Aluminum Magnesium Characteristics
Good paint adhesion
Excellent cutting edge corrosion resistance
Superior scratch resistance
Good rub resistance
Excellent peel resistance
Good spot welding performance
Superior laser welding performance
Excellent bonding properties
The Zinc Aluminum Magnesium coating structure consists of primary Zn phase, Zn/MgZn2 binary eutectic phase, and Zn/MgZn2/Al ternary eutectic phase.
Frequently Asked Questions
Is it okay to use Galvalume with pressure-treated lumber?
Generally, no. The chemicals in modern pressure-treated wood (like ACQ) are highly corrosive to Galvalume. Use a barrier tape or physical separator between the wood and metal.
Does Galvalume require regular maintenance?
Very little maintenance required. However, areas not washed by natural rainfall (like under eaves) should be rinsed with fresh water annually to remove accumulated salts and dust.
What kind of fasteners should be used with Galvalume?
Always use high-quality stainless steel or zinc-aluminum capped fasteners. Never use carbon steel fasteners as they will rust and stain the panels.
How should Galvalume coils or sheets be stored?
Store in a dry, well-ventilated area. If stored outdoors, tilt to allow water drainage and cover with a breathable tarp.
Is Galvalume steel recyclable?
Yes, it is 100% recyclable. It can be melted down at the end of its life to produce new steel without any loss in quality.
