The main material of light steel villa is light steel keel

Light steel villa, also known as light steel structure house, its main material is light steel keel synthesized from hot-dip galvanized aluminum steel strip through cold rolling technology. The aluminum-zinc alloy structure of galvanized steel sheet is composed of 55% aluminum, 43.4% zinc and 1.6% silicon solidified at a high temperature of 600°C. The entire structure is composed of aluminum-iron-silicon-zinc, forming a dense quaternary crystal. So as to form a strong and effective barrier to prevent the penetration of corrosive factors.

The reason why light steel villas are more and more popular is that light steel has the following characteristics:

1. Corrosion resistance: The corrosion resistance of "55% aluminum-zinc-plated steel coil" comes from the barrier layer protection function of aluminum and the sacrificial protection function of zinc. When zinc is used for sacrificial protection on the cut edges, scratches, and scratches of the coating, aluminum forms an insoluble oxide layer to play a barrier protection function. The aluminum-zinc alloy steel coil has been subjected to outdoor exposure tests for more than 20 years in various atmospheric environments, and it has been proved that the cutting edge protection function of 55% aluminum-zinc steel plate is better than that of galvanized steel plate and 5% aluminum-zinc steel plate. good.

2. Heat resistance: The heat resistance of 55% aluminum-zinc alloy steel plate is better than that of galvanized steel plate, which is similar to the high temperature oxidation resistance of aluminized steel plate. Aluminum-zinc alloy steel plate can be used in high temperature environment up to 315 degrees.

3. Reflectivity: 55% aluminum-zinc alloy steel plate has high reflectivity, making it a heat-resistant barrier; the thermal reflectivity of aluminum-zinc steel plate is almost twice that of galvanized steel plate, so when it is not painted Serving as a roof and panel can also achieve energy saving effect.

4. Paintability: Due to the excellent adhesion between the zinc layer of the galvanized steel sheet and the paint, when used as a sign board for general purposes, it can be painted without pretreatment and weathering treatment; while galvanized steel sheet Need weathering and pretreatment.
