PRODUCT DESCRIPTION:
In addition to the tile roofing, the super lightweight galvanized steel truss frame is also used for the roofing system and other lightweight roofing materials.
STRUCTURE
With the use of C200 * 2.0ly bars as columns, C7575 bars for trusses and TS6175 bars as steel purlin for the galvanized steel roofing system, which helps to speed up construction because there is no welding, and not Anti-rust paint, in addition to its super light properties, will reduce the load on the foundation of the workshop greatly.
