1. Improve the surface flatness of high quality galvalume steel coating steel coil. After finishing, the flatness of the galvanized aluminum coil is improved, and the wave shape of the galvanized aluminum coil is partially eliminated, and the surface slag particles or other uneven spots can be flattened to make the surface smooth and flat. 

2. Adjust the roughness of the surface of the hot sale aluminum zinc steel coil. By controlling the roughness of the surface of the work roll of the finishing machine, the original uneven roughness of the surface of the galvanized aluminum plate can be unified to a certain range. This improves the paintability of the product and the lubricity during processing. 

3. Improve the surface color of high quality galvalume steel coating steel coils. For small zinc flower and zinc-free flower products, the galvanized aluminum plate can achieve a more uniform surface with gloss by finishing. For some private enterprises, the use of large zinc flower products as color-coated substrates can make the zinc flower bumps and different glosses formed by the large zinc flower crystals smooth and uniform, which makes the zinc flowers blurred and unfavorable. Cover the zinc flower when painting.

4. Improve the processing of GL Galvalumed coil performance. By finishing, the yielding platform of the galvanized aluminum coil can be eliminated or become inconspicuous, and the metal slip line can be prevented from being generated in the subsequent processing.

What Is Galvalume Steel Coil


By Alisajpq, 2019-03-01

The high quality galvalume steel coating steel coil is a multiphase alloy material containing aluminum-rich and zinc-rich. Because of the characteristics of aluminum and zinc, it has better performance than hot dip galvanized steel sheet (SGCC). 

Main characteristics: corrosion resistance, its ability is much higher than SGCC; heat resistance; heat conduction and heat reflection; formability; weldability. 

Uses: Used in some places that require good reflection, such as the reflector inside the oven, the reflector of the electric pot. Taiwan's shengyu steel corporation can produce. The price is much more expensive than the SGCC. Hot dip galvanized steel sheet (SGCC) is generally used, high quality galvalume steel coating steel coil is deep drawing, and SGCE is uultra-deepdrawing.
