Light Steel Villa

Introduction of Light Steel Villa

Light steel villa, also known as light steel structure housing, its main material is hot 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-si-zinc, forming dense quaternary junction crystal, thus forming a strong and effective barrier to prevent corrosion factors from penetrating.

Aluminum Zinc Plate Characteristics

Corrosion resistance:

The corrosion resistance of "55% aluminum-zinc plated steel coil" comes from the barrier protection function of aluminum, and the sacrificial protection function of zinc. When zinc is sacrificed to protect the cut edges, scratches and scratches of the coating, aluminum forms an insoluble oxide layer that ACTS as a barrier. Aluminum zinc alloy steel coil has been in a variety of different atmospheric environment, carried out more than 20 years of outdoor exposure test, confirmed that 55% aluminum zinc plate has the edge protection function, better than galvanized steel plate and 5% aluminum zinc plate.

Heat resistance:

The heat resistance of 55% al - zn alloy steel plate is better than that of galvanized steel plate. Aluminum zinc alloy steel plate can be used in high temperature environment up to 315 degrees.


The aluminum zinc alloy steel plate coated with 55% has a high reflectivity, which makes it a barrier against heat. The thermal reflectivity of aluminized zinc plate is almost twice that of galvanized steel plate. Therefore, it can be used as roof and panel without painting to achieve energy saving effect.

The lacquer on:

Because of the excellent adhesion between the zinc layer and the paint of the aluminum-zinc plate, it can be painted without pretreatment and weathering treatment when used as the marking plate for general purposes. Galvanized steel sheet needs weathering treatment and pretreatment.

Light steel villa system construction

Light steel wall structure system, by light steel multi-rib beam and column and in line with the maintenance of the structure common stress, various physical performance indicators excellent, short construction period, good insulation effect, is a new type of green energy conservation and environmental protection of the building structure system.

1. Basic system

Light steel structure houses are light in weight, only 1/5 of the brick-concrete structure houses, about 1/8 of the reinforced concrete structure houses, so it can greatly reduce the cost of foundation construction, light steel structure buildings generally use strip foundation.

(1) light steel structure light weight, can greatly reduce the cost of foundation engineering;

(2) basic moisture-proof design, effectively prevent moisture and harmful gas intrusion;

(3) reasonable anchoring way, to ensure that the foundation and the main body of the reliable connection.

2. Wall system

The external wall system is generally between 120-200 mm. Due to the thin and thin wall, the actual usable area of the light steel structure house is increased by 10%-15% compared with the traditional house, and the indoor usable area is increased by more than 90% compared with the traditional house. The indoor space can be divided flexibly. The pipeline can be arranged in the holes reserved in the wall, floor and roof components, with good concealment and more beautiful appearance.

(1) the wall is filled with glass fiber cotton, with good insulation, heat insulation, sound insulation performance;

(2) breathing paper waterproof through steam, can effectively adjust the indoor air humidity, make the living more comfortable, and effectively prevent the growth of mold inside the wall;

Pipeline buried in the wall, do not take up indoor space.

3. Floor system

The floor is composed of high-strength hot-dip galvanized c-type and u-type light steel components. The floor beams are arranged according to the standard modulus of equispaced rib. The floor beams are covered with the structural plates that have been strictly moisture-proof and anticorrosive to form a solid earthquake-resistant floor system.

(1) structural plate and floor steel beam combination structure, strong and stable;

(2) all kinds of water and electricity pipelines hidden in the floor structure, do not occupy the building storey;

(3) in the sandwich filled with glass fiber cotton, thermal insulation, sound absorption sound insulation effect is significant.

4. Roofing system

Roof by a variety of light steel components assembled and assembled, generally have triangular roof and t-shaped roof, can easily and flexibly achieve a variety of complex roof modeling, general roof with colorful asphalt tile, with good waterproof performance, highlight beautiful and quality.

(1) composite roof with rain, weather, heat insulation and other functions, can achieve a rich variety of modeling;

(2) ventilation circulation design, always keep the air fresh.

5. Structural components

All structural components are made of high strength galvanized steel to ensure the service life of the house. All the structural components are cold-pressed by the factory precision mechanical assembly line, and the size accuracy is millimeter meter, which cannot be matched by other structures.
