Hot-dip galvanized steel coils are available with a pure zinc coating through the hot-dip galvanizing process. It offers the economy, strength and formability of steel combined with the corrosion resistance of zinc. The hot-dip process is the process by which steel gets coated in layers of zinc to protect against rust. It’s especally useful for countless outdoor and industrial applications.

They are mainly used in building roof, door, window, roller shutter doorand automobile’s vehicle shell, chassis, door, trunk lid, Oil tank, and fender, and also electric equipments, such as refrigerator base and shell and so on.

Strong corrosion resistance, 3 times that of galvanized steel sheet.
The density of 55% aluminum is smaller than the density of zinc. When the weight is the same and the thickness of the plating layer is the same, the area of the galvalume steel sheet is 3% or larger than that of the galvanized steel sheet.

The common prepainted galvanized steel coil colors include sky blue, grey, silver, traffic red, moss green, olive green, leaf green, etc.
Welcome to send us a RAL color code or pattern or a sample to customize your own PPGI coated coil.

Note: The actual color may differ slightly due to the different coating materials, light, etc. But we promise to use the paint as agreed upon in the contract.

1.The cold-rolled coil products are accurate in size, uniform in thickness, and the thickness difference of the coils generally does not exceed 0.01-0.03 mm or less, which can meet the requirements of high-precision tolerances.

2.It is possible to obtain extremely thin strips that cannot be produced by hot rolling (up to 0.001 mm or less).

3.The surface quality of cold-rolled products is superior, there are no defects such as pitting, hot-pressed iron oxide, etc.,which are often found in hot-rolled coils, and coils of different surface roughness (glossy or hemp) can be produced according to user requirements. Rough surface, etc., to facilitate the processing of the next process.

4.The cold rolled plate has a good mechanical properties and process properties (such as higher strength, lower yield limit, good deep drawability, etc.).

5.High-speed rolling and full-continuous rolling can be realized with high productivity.

Hot rolled steel coils are used in the manufacture of steel structures, pipes and closed sections, as well as closed structures and façade elements. Profiled and round tubes are used in the industry mainly for

1. Steel structures and frames to support industrial and civil facilities
2. Protective covers for various utility lines (wires and cables, plastic or other pipes)
3. Support for major pipelines, water supply lines and heating networks, bridges and trestles
4. Sewer lines, flue pipes and ventilation systems
5. For road construction – utility poles, guide rails, drainage elements, lighting posts and crash barriers
6. Steel structures for sports fields and children’s playgrounds, vertical fences and partitions and other solutions

Key requirements for such rolled products in this market segment include minimum dimensional tolerances, heavy coil weights, weldability, high strength and toughness, resistance to cracking (also at negative temperatures) and external resistance for certain specific spheres. Recently, there has been a trend in the construction sector to replace cold rolled steel products with cheaper, thin hot rolled products. However, high-strength rolled product types are now widely used to reduce the weight of products.
