What is the difference between light steel villas and heavy

In recent years, the steel structure construction industry has developed rapidly, with more and more people building steel structure villas not only in urban and rural areas, but also in many professional steel structure construction teams. We know that steel structure villas can be divided into light and heavy ones, so what is the difference between the two? Is it better to choose light steel villas or heavy steel villas for rural housing construction? Let's take a look together.

 

1、 Differences between light steel villas and heavy steel villas

 

 

1. From the perspective of the main materials used in the construction of the villa, the light steel villa is made of hot-dip aluminized zinc plated steel plates, which have good corrosion resistance and long service life. Chongqing Steel Villa uses national standard H-shaped steel to construct the main frame of the villa, which has a stronger load-bearing capacity.

 

 

2. From the perspective of rust prevention ability: since the light steel villa does not use blanching technology and does not damage the zinc film, the rust prevention ability of the building is improved, and the main structure can even be used for hundreds of years. The main structure of Chongqing Steel Villa is connected with high-strength carbon steel nuts according to national standards, and rust removal is generally carried out by spraying finish paint and antirust film. The two rust prevention processes are also different, and generally, the rust prevention ability of light steel villas is better.

 

 

3. From the perspective of thermal insulation: A layer of thermal insulation cotton is installed inside the wall of the light steel villa, which can achieve the function of thermal insulation in winter. The exterior wall of the heavy steel villa is made of a special composite material, which not only can provide thermal insulation, but also can be waterproof and fireproof, and is superior in performance to thermal insulation cotton.

 

4. From the perspective of construction difficulty: If you choose a light steel villa, you do not need to use additional large tools during construction, which not only reduces the construction difficulty of construction workers, but also saves construction costs. The basic materials of Chongqing Steel Villa require the use of a crane to operate, so the construction process of Chongqing Steel Villa is more difficult.

 

 

5. From the perspective of safety: The light steel villa is physically connected with screws and structural fasteners. The wall is of a light steel keel structure, which is fixed with spray bolts, and has poor wind resistance stability. The main structure of Chongqing Steel Villa is closely combined with the foundation through L-shaped embedded parts to form a unified whole. In addition to the characteristics of the steel itself, it is suitable for areas with a magnitude 9 earthquake and above, with a wind resistance rating of 14-18.

 

 

1. Comparison of main structural materials of the house

 

 

The light steel villa is made of hot-dip aluminized zinc plated steel plates, with a conventional thickness of 0.8mm-1.2mm. This framework has good corrosion resistance and long service life.

 

Chongqing Steel Villa adopts international Q235 hot-rolled H-shaped steel 250 * 125 * 6 * 9 to construct the main frame of the villa, which has a stronger load-bearing capacity.

 

 

Summary: Heavy steel villas and light steel villas use different steels, specifications, and amounts of steel.

 

2. Different rust prevention capabilities

 

 

Light steel villas: Generally, self-tapping screws are used, without welding technology, and without damaging the zinc film. Therefore, the rust prevention ability of the building is greatly improved, and the main structure is well protected, which can even be used for hundreds of years.

 

 

Chongqing Steel Villa: The columns and beams are organized with international grade 10.9 high-strength bolts, without welding. The steel factory performs shot blasting, hot galvanizing, and corrosion prevention, or adopts a painting process. Painting is a anti-corrosion process of one primer plus two finishing coats, using the method of spraying the finishing coat and antirust film.

 

 

Summary: The rust prevention process of light steel villas is different from that of heavy steel villas. Generally speaking, the rust prevention ability of light steel villas is better.

 

 

3. The seismic and wind resistance performance of the house is very good

 

 

 

Light steel villa: Physically connected with screws and structural fasteners, the foundation and main body are designed to resist uplift and wind, making the entire building truly form a whole, with excellent wind and seismic performance.

 

 

 

Chongqing Steel Villa: The main structure is closely combined with the foundation through L-shaped embedded parts to form a unified whole. With the characteristics of the steel itself, it is suitable for areas with an earthquake magnitude of 8 or above, and the wind protection level is 12.

 

 

 

Summary: Both light steel villas and heavy steel villas have excellent seismic and wind resistance performance, and generally speaking, heavy steel villas are better.

 

 

 

4. There are also differences in construction difficulty

 

 

 

If you choose a light steel villa, you do not need to use additional large tools during construction, which not only reduces the construction difficulty of construction workers, but also saves construction costs. The construction process of a heavy steel villa is even more difficult.

 

 

 

5. There is also a significant difference in construction costs

 

 

 

From the perspective of cost, light steel villas have lower costs and faster construction speed during the construction process. Heavy steel villas not only have a long construction cycle, but also require additional use of professional tools for construction. Although light steel villas are made of lightweight materials, they have a solid structure, excellent seismic performance and wind resistance, and can meet the multi-functional needs of users. Chongqing Steel Villas have high costs, high requirements for construction workers and construction materials, and more diversified wall functions, good noise and sound insulation effects, and stronger load-bearing capacity.
