Large Span Residential Steel Construction Prefabricated Structural Steel Portal Frame
Product Description:
Prefabricated Steel Structure is an effective and economical solution for industrial or commercial building projects. It is a kind of portal frame structure, which is composed of columns, beams, bracings and purlins. It is made of quality metal materials, and can be painted or galvanized for better durability and corrosion resistance. The size and length of the structure can be customized according to your specific requirements.
Portal frame structure is an ideal and cost-effective choice for industrial or commercial buildings, which offers a wide range of advantages, such as quicker construction, less material waste, better airtightness, and better seismic performance. Moreover, prefabricated steel structure is very suitable for long-span or large-span buildings, as it can provide great flexibility and stability.
Applications:
Prefabricated Steel Structure. It is featured by large span, column, beam, bracing, purlin and grade of Q235 , Q355. It is of customized length and portal frame, and the size can be customized.
Prefabricated Steel Structure is widely used in bridges, towers, workshops, warehouses and other large span steel structures. It is also suitable for large scale industrial plants, and can be used for various types of buildings with large span. It can be used to construct plants, warehouses, office buildings, gymnasiums, hangars and large span buildings in airports. It also can be used for large span exhibition halls, large span sports venues, and other large span buildings.
| Product Application |
| Light Frame Steel Construction Hangar Design Prefabricated Steel Structure Factory Building Workshop warehouse |
| A pre-engineered steel building is a modern technology where the complete designing is done at the factory and the building components are brought to the site and then fixed/jointed at the site, all is bolt connection, no need any welding! |
| An efficiently designed pre-engineered building can be lighter than the conventional steel buildings by up to 30%. Lighter weight equates to less steel and potential price savings in structural framework. |
