Can be adapted for long spans! Steel-concrete composite slabs with high load-bearing capacity and durability.
"Pipe Slab" is a steel concrete composite floor slab consisting of steel plate panels made of ribs and pipes (structural steel tubes) that are integrated with concrete. It can accommodate long spans and has a large load-bearing capacity and high durability. The structure, which allows pipes to pass through the rib's long holes, functions as a restraint against concrete displacement. Additionally, since the inside of the pipes is hollow, it can reduce the weight of the concrete. 【Features】 ■ Restraint structure ■ Lightweight structure ■ Secondary use of the interior of the pipes ■ Material properties of the pipes ■ Panel joints *For more details, please refer to the PDF materials or feel free to contact us.
