Self Supporting Girder Steel Decking Machine


Jinggong self supporting girder steel decking machine adopts advanced mechanical, electrical, hydraulic and pneumatic technologies. Under microcomputer control, it can automatically complete the whole production process, from steel girder production, bottom plate forming, to steel form assembling and welding. The annual production capacity for single shift achieves 300,000 square meters.

Main Components

Our steel decking forming machinery is composed of steel girder production line, bottom plate forming machine, and steel form spot welder etc.


Self supporting steel deck is a new-type building material. Due to its light structure and high strength, self supporting girder steel decking machine is increasingly used in steel structure buildings, bridges, and railways, among others. Concrete can be directly poured on the self supporting steel deck, which greatly reduces workload and shortens construction cycle.

Advantages of Steel Decking Forming Machinery

1. A wide range of steel structure machines is available in our company, which includes shot blasting machine, bending machine, digital folder, and drilling machine etc.
2. These have been awarded the ISO9000 and CE certificates. Thanks to their high quality and low prices, our products are exported to many countries, such as America, Australia, Bulgaria, Argentina, Egypt, Syria, India, and more.
