Truss deck system

Duowei has been committed to researching and developing the truss deck system and has successively released an array of steel bar truss deck series into the market. These series include TDV, TDM, TDD(Z), TDD(Y), and WJ designed to meet the varied demands of customers across a vast range of projects, highlighting unique Duowei features. We prioritize providing customers with high-quality products and services backed by our specialized technical service teams, excellent manufacturing equipment, and serialized products.

TDV/TDM steel bar truss deck

Duowei TDV/TDM steel bar truss deck is a combined formwork formed by processing the load-bearing bars in the truss deck into steel bar truss in the factory and then welding the steel bar truss and the bottom mold of the galvanized profiled steel into a whole. It has the advantages of "economy, convenience, safety and reliability" and it is a truss deck product that can improve customers' value. After more than ten years of development, it has been widely used in the floor or roof system structures of prefabricated steel structure buildings and concrete buildings.

TDD(Z) and TDD(Y) Detachable Steel Bar Truss Deck

Duowei TDD(Z) detachable steel truss floor deck is a type of combined formwork, made by processing load-bearing bars into steel bar trusses in the workshop and then connecting them to the bottom mold with plastic fasteners and self-tapping screws, to create a one-piece structure. After the poured concrete reaches the design strength, the bottom mold is removed, and the surface is finished with putty or paint to create a slab bottom effect that matches the appearance of a cast-in-situ reinforced concrete floor.
Duowei TDD(Y) detachable steel truss floor deck is a type of combined formwork, made by processing load-bearing bars into steel bar trusses in the workshop and then connecting them to the bottom mold with steel plate connectors and self-tapping screws, to create a one-piece structure. After the poured concrete attains the design strength, the bottom mold is removed, and the surface is completed to create either an industrial-style slab bottom effect by directly spraying finish paint or an appearance that aligns with that of a cast-in-situ reinforced concrete floor by leveling with light sticky gypsum before finishing with putty.

WJ® Undetachable Steel Bar Truss Deck

Duowei WJ® undetachable steel bar truss deck is a novel type of deck product, featuring a permanent bottom mold made of fiber cement board, which significantly reduces support formwork and entirely eliminates erecting formwork, making it ideal for projects that require a direct finishing on the slab bottom rather than using suspended ceilings.
