What are the advantages of Jianyi heavy steel villa compared with light steel villa?

1. main structure of light steel villa: the main structure adopts hot-dip galvanized steel strip as light steel dragon skeleton, and the conventional thickness is 0.8/ 1.2. Chongqing steel villa: the main structure adopts the national standard H-beam as the main frame, with a thickness of 6/9. Through the comparison of the above main structures, it is concluded that the steel, specifications and steel consumption used in heavy steel structure villas and light steel structure villas are different. 2. Anti-corrosion technology Light steel villa: Self-tapping screws are used instead of jointing technology, which effectively protects the integrity of zinc film, so the anti-corrosion performance is excellent. Chongqing steel villa: columns and beams are assembled with national standard high-strength carbon steel nuts without welding. The iron and steel plant carries out manual derusting, and one primer and two topcoats are treated with anti-corrosion technology, and a layer of anti-rust film will be plated after installation. 3. Safe light steel villa: it is physically connected by Dacromet screws and structural fasteners, and the foundation and main body are designed to resist uplift and wind, so that the whole building truly forms a whole with excellent wind and earthquake resistance. Villa. Chongqing steel structure villa: the main structure is closely combined with the foundation through L-shaped embedded parts to form a unified whole. Combined with the characteristics of steel itself, it is suitable for earthquake areas with magnitude 9 and above, and the windproof grade is 12. 4. Thermal insulation light steel villa: thermal insulation cotton is built into the wall, and the northern outer wall can be used as an integrated thermal insulation decorative board to achieve the effect of thermal insulation (the integrated board has high thermal insulation cost). Chongqing Steel Villa: The external wall adopts special high-strength composite wallboard, which has the effects of waterproof, fire prevention, heat insulation and heat preservation. Compared with red brick or light brick, it has better comfort and bearing capacity, and the roof adopts thermal insulation layer, which makes the whole villa warm in winter and cool in summer. 5. Bearing capacity of light steel villa: the bearing capacity is weak, and it can only bear the weight of 350 kilograms per square meter, with a small span. Every 60 cm, there must be a pillar to support it, which leads to the maximum span of the whole villa not exceeding 6 meters, while the traditional concept in China requires the living room to be large, generally exceeding 6 meters. In addition, it is also very troublesome to adjust the layout of the house in the later stage, and because light steel villas mostly use hollow walls, components must be embedded after keel installation to install water heaters and air conditioners. Chongqing steel villa: the dragon skeleton is made of national standard H-beam, with a bearing capacity of 850KG square and a span of10m. The ground is paved with galvanized corrugated steel bottom plate, and the whole network is rolled with cross steel frame. Cement mortar pouring 10cm, good integrity, heavy and practical. At the same time, the wall itself is solid, and the single-point bearing capacity of special high-strength composite wallboard can reach 100 GK/. Drilling, cutting and grooving can be done at any time. 6. Exterior wall decoration (appearance) and service life of light steel villa: cement fiber hanging boards are generally used for exterior walls, which will fade in sunny areas for 2-3 years. The roof tile is made of resin tile, which looks very thin, which is the main reason why the light steel villa needs maintenance in the later period. Chongqing Steel Villa: The exterior wall is a solid wall, so the exterior wall can be decorated with exterior wall tiles, or with real stone paint, and the roof material is made of tiles, which is relatively atmospheric and conforms to the traditional aesthetics, and does not need maintenance at all. Who is better, heavy steel or light steel? I believe that the market and time will verify everything, but from the current market feedback, Chongqing steel villa is undoubtedly the upper hand, making it easier for people to recognize and choose. Prefabricated buildings are the development trend, which will replace the traditional brick-concrete buildings sooner or later, thus improving the overall living environment.
