High quality steel structure and long service life. All main parts are hot dipping galvanized after processing according to European standards, guarantee excellent anti-corrosion.
Prefabricated structure. All the parts can be easily assembled on the spot with joining parts and bolts and nuts, without any welding points to damage the zinc coating on the material, which guarantee the optimal performance of anti-corrosion.
The standardization production of all the parts
Ventilation configuration: roof vents and side vents, controlled by rack and pinion system
