Enclosure System Wall/Roof Panels
Features of Portal Frame Steel Structure Workshops:
Large Span, Flexible Layout
Common spans range from 12 to 36 meters, with even larger spans possible. The absence of internal columns allows for flexible arrangement of cranes, assembly lines, storage racks, and other equipment.
Economical Steel Consumption
Compared to traditional concrete structures, portal frames are lighter, have lower foundation costs, and optimized overall steel consumption, resulting in a more competitive overall cost.
Short Construction Cycle
Prefabricated steel components in the factory and connected on-site with high-strength bolts allow for rapid construction, unaffected by seasonal changes, and significantly shorten the construction period.

Safe, durable, and highly earthquake-resistant
Made with high-strength steel such as Q355B, treated with anti-corrosion and fire-retardant coatings; excellent structural ductility and superior earthquake resistance, meeting national standards and safety regulations.
Scalable and easily modifiable
The regular structural system facilitates future additions, expansions, or upgrades to internal equipment, adapting to changes in business development.
Modern appearance, compatible with various enclosure systems
Can be combined with color steel sandwich panels, single-layer profiled steel sheets, skylights, insulation layers, etc., meeting multiple needs such as insulation, heat insulation, ventilation, and lighting.

Portal frame steel structure workshop factory is widely applicable to various industrial and civil building scenarios such as machinery manufacturing, auto parts, electronic assembly, logistics warehousing, and agricultural product processing.
