Aluminum Zinc Alloy Structure Light Weight Steel Villa With Corrosion Resistance

Aluminum-zinc Alloy Structure Light Weight Steel Villa with Corrosion Resistance

Light steel villas, also known as light steel structure houses, are mainly made of hot-galvanized aluminum steel strips and cold steel keels synthesized by cold rolling technology.
The aluminum-zinc alloy structure of the galvanized steel sheet is composed of 55% aluminum, 43.4% zinc and 1.6% silicon at 600 ° C. The whole structure is composed of aluminum-iron-silicon-zinc, forming a dense quaternary crystal. Thereby forming a layer of a barrier that effectively prevents the penetration of corrosion factors.

Characteristics of galvanized steel sheet:
Corrosion resistance:
The corrosion resistance of the "55% aluminum-zinc steel coil" comes from the barrier function of aluminum and the sacrificial protection of zinc. When zinc is sacrificed for trimming, scratching, and scratching of the coating, the aluminum forms an insoluble oxide layer that acts as a barrier. The aluminum-zinc-plated alloy coil has been tested for outdoor exposure for more than 20 years in various atmospheric environments, confirming the trimming protection function of the 55% aluminum-zinc plate, compared with galvanized steel and 5% aluminum-zinc plate. good.
Heat resistance:
The heat resistance of the plated 55% aluminum-zinc alloy steel plate is better than that of the galvanized steel plate, and is similar to the high temperature oxidation resistance of the aluminum plated steel plate. Aluminized zinc-alloyed steel sheets can be used in high temperature environments up to 315 degrees.
Reflectivity:
The 55% aluminum-zinc alloy steel plate has a high reflectivity, making it a heat-resistant barrier; the aluminum-zinc steel plate has almost twice the heat reflectivity of the galvanized steel plate, so it acts as a roof and embedded in the unpainted case. The board can also achieve energy saving effects.
Lacquering:
Due to the excellent adhesion between the zinc layer of the galvanized steel sheet and the paint, when used as a signboard for general use, it can be painted without pretreatment and weathering; while galvanized steel sheets require weathering and pretreatment. .
Light steel villa system construction
The light steel wall structure system is made up of light steel ribbed beams and columns and the maintenance structure. The physical properties are excellent, the construction period is short, and the heat preservation effect is good. It is a new type of green energy-saving and environmentally-friendly building structure system.

Light steel villa has some featured advantages below:

Stable steel structure: The mainly structure of prefab house is light steel structure and sandwich panel. They form a stable structure so it can resist 9-10 grade hurricane and 7-8 grade earthquake.

Quick Installation: One team skilled workers can finish installing 100m2 prefab villa in several days.

Flexible layout: The partition wall, window, ceiling, elevating flooring, eaves and color steel door are optional for clients.

Long service life: The components of house can be used repeatly, so its service life can reach up to more than 25 years without any building garbage.

Used widely: Light steel villa can be built widely in the scenic site and around the seashore for holiday house or other usages.

Excellent performance: Fire-proof, water-proof, sound and heat insulation.

Applications:

The complete house can high space utilization and have unique appearance. This kind of products are Particularly suited to scenic areas, leisure homes, such as mountain villas, lakeside-view villas, restaurants ,Chess House and so on.
