Hot-dip Galvanized Steel Sheet

Feb 22, 2017

Hot-dip galvanized steel sheet in various strengths and thickness specifications of cold-rolled steel plate for the base material, double hot-dipped galvanized coating as proceeds of a Al-Zn coating on the plates, coating composition quality percentage-55%Al, 43.5%Zn and 1.5%Si, combines Al physical protection and durability of high and Zn of electrochemical protection features. In addition, the surface has a high decorative light silver-gray Jersey and pattern of the rule, and has a floating sense of convex.

Aluminum-plating Zinc plate proved to have the following features: extraordinary weather resistance and used for more than 20 years without maintenance. Recently the roof/wall system of early product test results show that aluminum-plating Zinc plate in decades of strong sun light, exposure, industrial waste under the action of temperature stress of erosion and, good performance no maintenance is required.

Over 500 million square meters of the world project examples make the aluminum-plating Zinc plate is more architects and owners of all ages. Excellent corrosion resistance performance, innovative design style is the reason the roof/wall system widely. Studies show that current roof system in the majority of cases expected to reach more than the service life of 30 years or even a longer period, without maintenance.

1. color plating Al-Zn coated steel substrates for light weight and high strength steel.

2. by continuous hot dip treatment, aluminum-zinc alloy plating layers formed on both sides of the plate, after 20 years of different environments, field test was confirmed in the same environment, durable than galvanized steel aluminum-plating Zinc plate four times or more.

3. aluminium zinc plated steel coated with chemical coating, on chemical film coating on corrosion resistance of epoxy primer, increased corrosion protection function.

4. surface coated coated with weather resistance excellent colored special coating strong polyester, ensure aluminum-plating Zinc plate can use for many years and still keep their original color and gloss, coated with light gray paint at the bottom makes the steel more beautiful.
