Light steel villa, also known as light steel structure housing, its main material is made of hot dip galvanized aluminum steel strip by cold rolling technology synthesis of light steel keel. The aluminum-zinc alloy structure of aluminum-zinc plated steel plate is composed of 55% aluminum, 43.4% zinc and 1.6% silicon solidified at 600℃. The whole structure is composed of aluminum-iron-silica-zinc, forming a dense four-element crystal, thus forming a layer of strong and effective barrier to prevent corrosion factors from penetrating.We can customize according to your drawings.
