Product Details

镀锌板-1.jpg


Galvanized steel sheet refers to a steel sheet with a layer of zinc on the surface for aesthetics and anti-rust purpose. It is most widely used in buildings and also applied as the base metal of color coated steel. Due to the different galvanizing processes, the zinc spangles will be different, including big spangles, regular spangles, small spangles, and zero spangles.

The substrate is hot rolling and cold rolling steel, which is with high strength, good processability, but is easy to corrosion. Through the galvanizing process, it will form a protective layer to prevent the substrate from rusting and prolong its service life. Here is how the zinc coating work: After zinc and oxygen reactions, there will be an oxide film to isolate the substrate from air and moisture to prevent oxidation. If the zinc layer scratches, somewhere around the zinc will melt to protect bare steel from corrosion.

The zinc layer thickness is usually expressed in Z + number. For example, Z275 refers to 275 g (20 µm) of zinc per square meter, which is the same as the G90 galvanized sheet. According to ASTM standards, G60 means the zinc layer is 180g/m2.

Product Introduction


Advantage

One of the main advantages of galvanizing steel is its superior resistance to corrosion and rust. This makes it ideal for use in outdoor environments where metal components would otherwise be exposed to harsh weather conditions. Galvanized steel does not require additional maintenance as its zinc coating will last many years without repainting or refinishing. This can save you time and money in the long run, as there’s no need for regular upkeep or repairs on your metal structures or equipment.


In addition, galvanized steel has excellent thermal properties, which make it suitable for use in commercial buildings such as warehouses and factories where insulation is essential. In this regard, galvanizing steel helps reduce energy costs since heat transfer between interior spaces and exterior surfaces is minimized. Furthermore, galvanizing steel allows you to achieve aesthetic effects with different types of finishes, including matte, semi-gloss, gloss, and satin finishes depending on your preferences.


• Galvanized steel is more durable than other types of steel.
• Galvanized steel is less likely to rust and corrode.
• Galvanized steel is easy to maintain.
• Galvanized steel is recyclable.

• Galvanized steel can be used in a variety of applications.


Types of GI Sheets

• Hot-dip Galvanized Steel Sheet

Hot-dip galvanized steel is made by immersing the steel sheet in a molten zinc bath at about 500 °C to attach a zinc layer to the surface. This is the continuous galvanizing process. It will form a protective zinc layer on the surface so that it has good paint adhesion and weldability. It is the most widely used and cost-effective method to prolong the service life of steel sheets. 

• Electro-galvanized Steel Sheet

Electro-galvanizing, also known as cold galvanizing, uses electrolysis to form a uniform and dense layer on the surface of the metal. The anti-corrosion zinc layer can protect steel parts from oxidation corrosion. Also, it can meet decorative purposes. But the zinc layer of the electro-galvanizing steel sheet is only 5-30 g/m2. So its corrosion resistance is not as good as hot-dip galvanized sheets.


The electro-galvanizing is suitable for small workpieces. And the electro-galvanized sheet is suitable for applications that require a high finish and interior applications, such as ceilings, window or door frames, and automotive panels. While hot-dip galvanizing steel sheet is more corrosion-resistant, which is a good choice for the outdoor environment. Its uses include roofing, doors, gutters, pipes, etc.

Applications

Galvanized steel is versatile in construction, furniture, home appliances, and the automobile industry due to its durability and affordable price.

• Construction industry – Due to its lightweight and durability, galvanized steel has been popular for over a century as building material, especially for roofing, floor deck and wall uses. Because of its aesthetics, it is suitable for different architectural styles. Besides, it is also widely used in fencing, grilles, gutters, rolling doors, pipes, etc.

• Automobile industry – The hot-dip galvanized sheets for the automobile industry are mostly from 0.6 mm to 1.2 mm in thickness. About 80% of the car body is made of galvanized steel because of its anti-corrosion. Also, it is also used to make shells, roofs, and floors of carriages, containers, etc. 

• Light industry, includes the casing of home appliances, chimneys, kitchenware, etc. It can be also found in agricultural uses or the furniture industry, such as granaries, billboards, etc.

• At Zhongxi Factory, we also make some finished products, such as galvanized tanks, chimneys, buckets, stoves, roofing sheets, door panels, etc. If you want more details, please contact us!
