Light steel villa

The light steel villa, also known as the light steel structure house, its main material is the light steel keel synthesized by the hot-dip galvanized aluminum strip through the cold rolling technology.
The aluminum zinc alloy structure of the 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 silicon zinc, forming a dense quaternary crystal, thus forming a strong and effective barrier to prevent the penetration of corrosion factors.
Characteristics of aluminized zinc steel plate:
Corrosion resistance:
The corrosion resistance of "55% aluminum zinc coated steel coil" comes from the barrier protection function of aluminum and the sacrificial protection function of zinc. When zinc is used as sacrificial protection in cutting edge, scratch and coating scratch, aluminum forms an insoluble oxide layer, which plays a barrier protection function. The aluminum zinc alloy steel coil has been exposed in various atmospheric environments for more than 20 years. It is proved that the edge protection function of 55% aluminum zinc steel plate is better than that of galvanized steel plate and 5% aluminum zinc steel plate.
Heat resistance:
The heat resistance of 55% Al Zn alloy steel plate is better than that of galvanized steel plate, which is similar to that of aluminized steel plate. The aluminized zinc alloy steel plate can be used in high temperature environment up to 315 ℃.
The 55% Al Zn alloy steel plate has a high reflectivity, which makes it a heat-resistant barrier; the thermal reflectivity of the Al Zn alloy steel plate is almost twice that of the galvanized steel plate, so it can also achieve energy-saving effect to act as the roof and panel without painting.
Due to the excellent adhesion between the zinc layer and the paint of the aluminized zinc steel plate, when it is used as the sign plate for general purpose, it can be painted without pretreatment and weathering treatment; while the galvanized steel plate needs weathering treatment and pretreatment.
Light steel villa system structure
The light steel wall structure system, which is composed of light steel multi rib beams and columns and consistent with the maintenance structure, has excellent physical performance indexes, short construction period and good insulation effect. It is a new type of green energy-saving and environmental protection building structure system.
