CFS-WMRC SLAB

The Panelized Buildings

Buildings Made with CFS-WMRC Slabs

The CFS-WMRC composite slab innovatively combines a cold-formed steel framework with a thin, high-strength, wire-mesh-reinforced concrete panel. Replacing conventional top flanges, unique finger-shaped connectors are punched directly from the steel joists and blocking plates, locking seamlessly into the concrete to ensure exceptional structural integrity. This advanced design allows the concrete to act as the primary compression element, maximizing material efficiency and its overall load-bearing capacity.

CFS-WMRC Slab with Cast-in Fingers

The Cold-Formed-Steel and Wire-Mesh-Reinforced Concrete (CFS-WMRC) composite slab is an innovative, highly versatile building component designed for modern construction. It utilizes novel finger connectors instead of traditional flanges to mechanically interlock the thin concrete panel with the steel frame, significantly boosting load capacity while minimizing weight. Engineered to easily integrate essential utilities like HVAC, electrical wiring, and plumbing, it is manufactured using a highly controlled prefabrication method for superior dimensional accuracy. Ultimately, this system delivers a thinner, highly durable, and fire-resistant structural element suitable for floors, walls, and roofs, dramatically reducing material costs, labor, and construction timelines.

Assembling a CFS floor frame

After precisely positioning the cold-formed steel (CFS) members, securely join them using spot welding, laser welding, or structural screws with metal connectors. Once primary framing elements like joists and tracks are secured, lay wire mesh over the finger-shaped connectors. Finally, weld the mesh to the connectors to guarantee maximum structural integrity.

The CFS Frame + WMRC Board

Prepare the casting bed, set up perimeter barriers, and place the inverted CFS frame onto it. Next, mix the concrete with fibers to meet the required design strength and consistency. Pour this mixture over the wire mesh and vibrate the bed to ensure even distribution and eliminate air pockets. Finally, allow the concrete to cure fully according to project specifications.

The Slab with HVAC Pipes

Secure the HVAC ducts directly to the joists using precision laser welding to provide strong, seamless joints for long-lasting durability. Ducting routed through joist utility holes provides added structural rigidity. Complex ductwork is completed off-site, significantly accelerating the final on-site assembly and installation process while reducing material and labor costs.
