Product Description

GUANXIAN 20-165G/M2 Alu-Zinc CoatingAl Zn Alloy Coated Aluminum Zin GL Galvanized Steel Metal Roofing Steel Sheet

Product Description

GALVALUME STEEL SHEET

Alu-Zinc steel, also known as galvanized steel or zinc-aluminum steel, is a cold-rolled galvanized steel with a metal coating consisting of 55% aluminum, 43% zinc, and 1.6% silicon. Its unique composition gives Alu-Zinc steel some unique properties, namely the physical protection and high durability of aluminum combined with the electrochemical protection of zinc.

Alu-Zinc is the fastest growing metal coating in the world. This is because steel has rapid strength, formability, and recyclability, while the aluminum-zinc alloy coating has proven long-term corrosion protection. This combination produces an affordable product with excellent environmental attributes such as durability, recyclability, energy efficiency, and utilization of scarce resources.

FEATURE

Aluzinc has a clean, natural, and bright silvery surface. The surface includes small spangles that give it a lustrous and striking appearance as light conditions change.

 Product Benefits

Corrosion Resistance: AlZn steel sheets are more corrosion-resistant than standard galvanized steel coils. The aluminum in the coating acts as a protective barrier, while the zinc acts as a sacrificial layer, adding an extra layer of corrosion resistance.

High Heat Resistance: AlZn steel sheets have an extremely high heat resistance, allowing them to survive high temperatures without major structural changes.

Formability and Machinability: AlZn steel sheets have an extremely high formability and are easily formed without cracking or breaking. This property makes them suitable for a variety of production procedures, such as bending, roll forming, and stamping.

Aesthetic Versatility: With a smooth, shiny surface, AlZn steel sheets offer aesthetic versatility. They can be coated in a variety of colors, coatings, and textures, providing unique solutions to match architectural designs and personal tastes.

THE MAIN PROPERTIES OF ALU-ZINC ARE:

Excellent resistance to corrosion and perforation
Aesthetic appearance -silvery metallic spangle
Good abrasion resistance due to its surface hardness
Excellent thermal and light reflectivity
Excellent resistance to high temperatures (up to 315°C)
Ease of working: profiling, deep drawing, bending, etc
Environment-friendly product - 100% chromium-free passivation
Product recommended for food storage

FEATURES OF ALUZINC STEEL COIL

* Superior long-term corrosion resistance allows aluzinc steel coils to outperform galvanized coating by 2 to 6 times.

* The density of 55% aluminum is smaller than that of zinc. With the same weight and thickness of the plating layer, the areaof the galvalume steel sheet is 3% or larger than that of a galvanized steel sheet.

PRECAUTIONS FOR USE

* The roof of the galvanized steel sheet building should have a certain slope to facilitate drainage and avoid corrosion, cutting should be carried out at the construction site; 

* during processing and stacking, the fingerprint-resistant film should be prevented from turning black due to moisture and high temperature;

* When the galvanized steel sheet used for foam bonding is used for the first time, a small piece test should be carried out to prevent weak bonding;
