Plywood With Steel Frame Formwork

A kind of steel frame plywood formwork, form by steel frame and plywood panel, steel frame has the special section of fin to constitute rectangular frame by rolling, it is characterized in that indulging rib to being provided with 1-4 bar channel-section steel along the length of steel frame, along steel frame laterally be provided with the band steel cross rib, plywood panel is connected with screw with steel frame and the vertical rib of channel-section steel.

With the rapid development of pure steel formwork and pure wood formwork, its advantages and disadvantages are gradually exposed, so some formwork companies began to study how to combine the advantages of this two kinds. They try to save materials costs and also improve the service life of the formwork. Finally, they find the steel frame with plywood. It is more conducive to transportation than all steel formwork, higher turnover utilization rate, and light weight, easy to assemble and install. So reflect the advantages of steel frame with plywood, which keep the steel frame and the panel use plywood. It reduced the total weight and raised the strength.So steel frame with plywood is gradually win the favor of some countries of construction and has been applied in many construction projects.

The plywood used in steel formwork is usually with thickness 15mm or 18mm. The material can be full birch or combi hardwood with birch. It has high elastic modulus and high bearing capacity.And also the PP plywood start to be used in steel frame formwork. Concrete forming effect is good. If they use good quality plywood such as WISA birch plywood and PP plywood, the turnover times of the formwork can reach more than 100 times.

We made the plywood size as customized. The length can be 3000mm, 2700mm,3300mm,2400mm, and the width can be 300mm, 600mm,900mm,1200mm,1500mm.
