Product Description

Portal Frame Steel Structure Construction building for Prefabricated Commercial Warehouse /Industrial Fabricated Workshop /Prefab Office
 

Product Description

Steel structure show case we have done before                                                                 QINGDAO STEEL BUILDING CO.,LTD

H Beam frame: weld H beam or hot rolled H beam

Hot Rolled H Beam:  Hot rolled H-beams are molded in one pass through the rolling mill according to their appearance and shape.no need for weld inspection.The processing volume of hot-rolled H-beam is small, and the construction period is slightly shorter,In the same section, the local stability of hot rolled
Weld H Beam: It can be processed, designed, and combined with any project, and can manufacture special specifications to meet the actual needs of special projects
