Light Steel portal frame consists of the lightweight welded H-shaped steel, hot-rolled H-shaped steel,

cold-formed steel , constituting a real-abdominal or portal frame lattice-type door frame as the main

load-bearing skeleton. Using cold-formed steel (C-shaped, Z-shaped, etc.) to do purlins, wall beams;

with pressed metal plate (pressure plate, pressure-type aluminum) to do roofing, wall; use of polystyrene

foam, rigid polyurethane foam, rock wool, mineral wool, glass wool, etc., as thermal insulation materials

and supported by appropriate settings of a light house architecture.

Green - Green frame, Green building materials.

Safe - Anti-seismic, anti-fire, anti-corrosion.

Durable - Galvanized high-strength steel frame.

Quality - We provide top-quality China made prefabricated steel buildings and accessories.

Cost - We pride ourselves in the fact that we always show our customers the best and least expensive way to accomplish their project.
