Prefabricated Steel Workshop Building with Galvanized Portal Frame
Product Features
- Fast construction speed: Prefabricated steel structures are manufactured in factories and only require simple installation at the site, significantly shortening the construction cycle.
- Good durability: Steel structure buildings can extend their service life through appropriate anti-corrosion treatment. The steel frame is made of ultra strong anti-corrosion and high-strength cold-rolled galvanized sheet.
- Strong construction flexibility: The construction process of prefabricated steel structures is flexible and adaptable, capable of accommodating various complex construction environments and conditions.
- High engineering quality: Prefabricated steel structures are manufactured and tested in factories, ensuring precise fabrication of components according to design requirements.
- Excellent seismic performance: Due to the high strength and ductility of steel, prefabricated steel structures exhibit superior seismic performance.
- Environmentally friendly and energy-saving: Prefabricated steel structures adopt zero-waste production, reducing the generation of construction waste.

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. |
