Product details

Galvalume steel (GL) coil is cold rolled or hot rolled steel plate made of zinc as matrix and aluminum as surface coating on zinc surface.

Galvalume steel (GL) coil is an aluminum-zinc alloy structure, which is composed of 55% aluminum, 43% zinc and 2% silicon solidified at 600℃. The whole structure is an alloy of aluminum-iron-silica-zinc to form a dense quaternary junction crystal.

Galvalume steel (GL) coil has many excellent features:

Corrosion resistance: The corrosion resistance of Galvalume steel (GL) coil is mainly due to the protective function of aluminum. When the zinc is worn, the aluminum forms a dense layer of alumina, preventing the corrosion resistance from further corroding the interior.
Thermal reflectivity: Galvalume steel (GL) coil has a high thermal reflectivity, twice that of galvanized steel, and people often use it as a thermal insulation material. Such as car mufflers, household appliances, etc.
Heat resistance: Galvalume steel (GL) coil has good heat resistance, can withstand the high temperature of more than 300 degrees Celsius, and the high temperature oxidation resistance of aluminized steel plate is very similar, often used in chimney tubes, ovens, illuminators and daylight lampshades.
Economy: Because the density of 55%AL-Zn is less than that of Zn, the area of Galvalume steel (GL) coil is more than 3% larger than that of the coated steel coil under the same weight and the same thickness of the gold plating layer.
In addition, Galvalume steel (GL) coil also has the characteristics of high aesthetics, environmental protection, energy saving and consumption reduction.

Product production process

Galvanizing refers to a rust-proof method of laying metallic zinc on the surface of iron or steel. Zinc is a metal with high corrosion resistance. It can insulate iron from oxygen and water, so that iron cannot undergo the chemical reactions required for rusting. Because zinc is more mobile than iron, even if the zinc plated appears Even if damaged, zinc can still prevent rust by electrochemical means of sacrificial protection. The main galvanizing methods include hot dip galvanizing (HDG), electro galvanizing (EG) and cold galvanizing.

Galvalume is a metallic material that is an alloy of zinc and aluminum coated on the surface of steel and is commonly used in the construction and manufacturing industries. Compared with ordinary galvanized steel sheets, galvanized materials have better corrosion resistance, longer service life, more beautiful appearance, and long service life. Therefore, it is a widely used material.

Color coating usually refers to a brightly colored, colorful and diverse coating, which is mainly composed of water-based resin, pigments and additives.
The purpose of color coating is to add baking coating technology to the surface of galvanized coils, galvalume coils or cold-rolled coils to apply paint on the surface.
The advantages of color picture boards are as follows:
Strong weather resistance: able to withstand damage caused by extreme weather, such as acid rain, ultraviolet rays, high temperatures, etc.
Good corrosion resistance: It can effectively prevent metal plates from being polluted and corroded, and extend their service life.
High aesthetics: It has a variety of colors and textures to choose from, which increases the decoration and aesthetics of the building.
Construction is convenient and fast: the color steel plates are made in the factory and installed at the factory, which is easy for factory planning, production and standardization, and reduces construction costs.

The main functions of steel roofing:
1. Prevent the influence of natural wind, snow, rain, solar radiation and low temperature in winter, so that the space under the roof has a good use environment. Therefore, steel structure roofs should meet requirements such as waterproofing, thermal insulation, heat insulation, sound insulation, and fire protection in structural design.
2. Bear the wind load, snow load and self-weight of the roof on the roof, and also provide horizontal support to the upper part of the house. Therefore, it is required that when designing the roof structure, the bearing capacity, stiffness and overall spatial stability of the roof components should be ensured.
What is the cost of a steel roof? This is closely related to a variety of factors, such as the quality of the project materials, the scale of the project, the difficulty of the project, etc., which all affect the price changes, so the cost of the steel structure roof cannot be To sum up, the best way is to give the most reasonable quotation budget based on the on-site construction conditions.
