All the purlins will be pinned connected by the high strength galvanized screw bolts.

The span of the building we can produce is from 6 meters to 21 meters. There is no problem if the customers need the span to be more than 21 meters, just increase the use of the steel material.

All the steel components are painted and anti-rust which can be normally used for more than 25 years.

Columns are bolted to the foundation and other steel components. The distance between two columns is 6 meters.

Wall panels are color steel sandwich panels made of double-sided steel sheets and expanded polystyrene middle layer with special adhesive this kind of EPS sandwich panels are heat&sound insulated.
