Today, the Easy assembled Villa supplier will take stock of its advantages and disadvantages.
1) Performance advantages
1. Lightweight, strong bearing capacity and large span
Compared with the traditional reinforced concrete brick house, Prefab House has a lightweight, but it has a strong bearing capacity! The load of the same layout house is only about 1/3 of the former, but the carrying capacity is almost the same. Not only can it reduce the requirements for the foundation, but it is also more convenient for transportation and construction.
The architectural style is more flexible and flexible, with a large bay design, and the indoor space can be divided into multiple schemes to meet the different needs of everyone.
2. The steel material is uniform, with good plasticity and toughness, and high seismic performance
The standardized production of the factory is destined for the uniform material of the load-bearing members of the steel structure, and the force-bearing performance of all parts is close, and it will not be as easily affected by human factors as reinforced concrete to cause defects.
The steel component has good plasticity and will not break and fail suddenly due to accidental overload or local overload. Good toughness makes the steel structure more adaptable to dynamic loads.
Coupled with the lightweight characteristics of steel structure, the seismic and wind resistance of steel structure villas are far superior to traditional houses. It has obvious advantages in ensuring the safety of the homeowner's personal property and the robustness of the house itself!
3. Industrialized production, easy manufacturing, and high precision
The production is simple and accurate. The finished components are transported to the site to be assembled and connected by bolts, which is convenient for construction. In addition, the built steel structure is also easy to disassemble, reinforce, or reform.

4. Short construction and installation period
The beams, columns, wall panels, and roofs are all assembled in a prefabricated installation method. It only needs to cast reinforced concrete on the floor. The construction speed is fast. Compared with the traditional house which can be built in a year and a half by Yu Dong, the construction period can be shortened by 2 3 or more! A house of 300 square meters can be easily handled by 5 workers in 1 month!
5. Energy saving and emission reduction, belong to green building
The wall adopts light-weight energy-saving standardized prefabricated wallboard instead of clay bricks. The use of sand, stone, cement, and water is small, and more than 80% of the materials can be recycled, saving energy and protecting the environment, especially in the construction site, with lower pollution.
6. Flexible decoration
The steel structure itself has a natural sense of heaviness and decoration. It can hold up the face without the need for other materials to be naked. With other decoration elements, it is full of modernity!
2) Performance disadvantages
Although steel structure villas have many of the above advantages, their shortcomings cannot be ignored.
1. Easy to rust and not resistant to corrosion
This is the biggest problem with low cost prefabricated houses. Without concrete protection, the steel structure is exposed to the air and it is easy to rust. Especially the places where the components are connected by welding are most susceptible to corrosion. Although galvanized paint can be used for improvement, it must be maintained regularly, otherwise, the service life of the steel structure villa will hardly exceed 20 years. Regular maintenance is very unrealistic for rural areas, especially in coastal areas where the air is humid and corrosive.
2. Heat and fire resistance
When the temperature is below 150°C, the properties of the steel change little. When the temperature is between 300°C and 400°C, the strength and elastic modulus of the steel are significantly reduced. When the temperature is about 600°C, the strength of the steel tends to zero. Therefore, relatively speaking, the fire resistance of steel structure houses is weaker than that of traditional houses.
3. Strong professionalism
Steel structure construction needs to find a professional construction team, especially the positioning, connection, and review of steel columns require skilled workers to carry out the construction, and the general construction team cannot do it.
Generally speaking, steel structure houses have obvious advantages over traditional structure houses, but the biggest hidden danger is corrosion. If you really plan to build your own house with a steel structure, you must use hot-dip galvanized steel and bolt connection!
Finally, if you want to build a house, which structure do you choose?
