Frequently Asked Questions

How about the cost of prefabricated building?
Prefabricated buildings are lighter and more economical than concrete buildings. Factory production significantly reduces labor intensity and installation time on-site.
How long is the service life of the portal H-type steel frame?
The service life of the main steel frame can last for up to 50 years.
Is the steel frame safe and stable?
Yes. It features Grade 8 earthquake resistance and Grade 12 wind resistance (wind speeds ≤ 120km/h).
What are the advantages compared to traditional buildings?
The main advantages are its lightweight nature, cost-effectiveness, low labor intensity, and rapid assembly speed.
How can I assemble the portal H-type steel frame?
All components are bolted (no soldering required). Walls and roof structures are fixed with self-tapping screws. We can also arrange technicians to guide installation on-site if needed.
Are custom sizes available for these buildings?
Yes, all dimensions and specifications can be customized according to customers' specific requirements and design parameters.
