What is the difference between light gauge steel framing and heavy steel villa houses?

In recent years, the steel structure construction industry has developed rapidly, not only in the city, 

but also in rural areas to build more and more people build steel structure villas, 

there are also many construction teams specializing in steel structure. 

We know that there are light and heavy steel structure villas, so what is the difference between the two? 

Rural housing in the end is the choice of light gauge steel framing or heavy steel villa houses good? Take a look at it.

First, the difference between light steel villa and heavy steel villa

1. From the construction of the main body of the villa materials:

Light steel villa is made of hot-aluminum-zinc-plated steel plate building skeleton, this skeleton anti-corrosion performance is good, long service life. 

The heavy steel villa uses the national standard H-type steel to build the main frame of the villa, and this kind of steel has a stronger load-bearing capacity.

2. From the rust resistance:

As the light steel villa does not use blanching technology, does not destroy the zinc film, so it improves the rustproof ability of the building, 

the main structure can even be used for hundreds of years. 

And heavy steel villa part of the main structure using national standard high strength carbon steel nut for connection, rust generally use spray paint and rust film way. 

Both anti-rust process is also different, generally light steel villa rust ability is better.

3. From the warmth:

Light steel villa wall internal set a layer of thermal insulation cotton, in the winter can achieve the function of heat preservation and insulation, 

and heavy steel villa outer wall is a special composite material made of wallboard, not only heat preservation and insulation, but also waterproof and fireproof, 

in the performance of better than the thermal insulation cotton.

4. From the construction difficulty:

If you choose light steel villa, you don't need to use extra large tools in building construction, which not only reduces the construction difficulty of construction workers, 

but also saves the construction cost. The basic materials of heavy steel villa need to use crane to operate, so the construction process of heavy steel villa is more difficult.

5. From the security point of view:

The light steel villa is physically connected with screws as well as structural fixtures, and the walls are light steel keel structure, fixed by spray boltwith poor wind stability. 

Heavy steel villa main structure through the L-type embedded parts and the foundation of a close combination to form a unified whole, coupled with the characteristics of the steel itself, 

suitable for 9 earthquake and above, wind level of 14-18.

1. Comparison of main structure materials

Light steel villa is made of hot-aluminum-zinc-plated steel plate, the conventional thickness of which is 0.8mm-1.2mm, which has good anticorrosion performance and long service life.

Heavy steel villa uses international Q235 hot rolled H steel 250*125*6*9 to build the main frame of the villa, this steel has a stronger load-bearing capacity.

Summarize: heavy steel villa and light steel villa steel, specifications, the amount of steel is not the same. 2.

2. Rustproof ability is different

• Light steel villa:

Generally use self-tapping screws, do not use welding technology, do not persecute the zinc film, so greatly improve the building's ability to prevent rust, well-protected main structure, 

and even can be used for hundreds of years.

• Heavy steel villa:

Columns and beams are organized through international 10.9 grade high strength bolts, no welding is used, and the steel factory carries out shot blasting and descaling, 

hot-dip galvanizing for anti-corrosion, or adopts spray painting process. Spray paint for a primer plus two surface paint anti-corrosion process treatment, with spray paint and rust film.

Summarize: light steel villa and heavy steel villa have different antirust process, generally speaking, light steel villa has better antirust ability.

3. The houses have good anti-seismic and wind-resistant performance

• Light Steel Villa:

Physically connected with screws as well as structural fixtures, the foundation and the main body adopt anti-drawing and windproof design, 

so that the whole building really forms a whole, windproof, and with excellent anti-seismic performance.

• Heavy steel villa:

The main structure through the L-type embedded parts and the foundation closely combined to form a unified whole, coupled with the characteristics of the steel itself, 

suitable for more than 8 seismic level of the region, the wind level of 12.

Summarize: light steel villa and heavy steel villa seismic and wind resistance are very good, generally speaking, heavy steel villa is better.

4. There is also a difference in construction difficulty

If you choose light steel villa, you don't need to use extra large tools during construction, which not only reduces the construction difficulty of construction workers, 

but also saves the construction cost, while the construction process of heavy steel villa is more difficult.

5. Construction cost difference is also relatively large

From the cost point of view, light steel villa in the construction process cost is lower, construction speed is faster, heavy steel villa is not only long construction cycle, 

but also need to use additional professional tools for construction, and light steel villa although the material is lightweight, 

but the structure is solid, seismic performance and wind performance is very good, but also meet the user's multi-functional needs. 

Heavy steel villa has high cost and high requirements for construction workers and construction materials, meanwhile, the wall function is more diversified, 

with good anti-noise and sound insulation effect and stronger load-bearing capacity.
