Product Description

OVERVIEW OF ALUZINC STEEL COIL

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.

Aluzinc is the world's fastest-growing metallic coating. This is due to the fast combined strength, formability, and recyclability of steel with the proven long-term anti-corrosion performance of the AI-Zn alloy coating. This combination results in an economical product with superior eco-friendliness attributes of durability, recyclability, energy efficiency, and scarce resource utilization.

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: Aluzinc steel coils 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: Aluzinc steel coils have extremely high heat resistance, allowing them to survive high temperatures without major structural changes.

Formability and Machinability: Aluzinc steel coils have 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, Aluzinc steel coils offer aesthetic versatility. They can be coated in a variety of colors, coatings, and textures, offering 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.
