Specifications-steel truss 1. Upper wire diameter : from 5-12mm 2. Lower wire diameter :from 5-12mm 3. Diagonal wire diameter: from 4-10mm 4. Steel truss length:from 3-12m 5. Steel truss width:100-150mm 6. Steel truss height: from 100-150mm Applications for steel truss: 1 steel truss applied to precast slabs, pre-high-speed railway sleeper. 2 used in many high-rise, ultra- high-rise steel buildings 3 used for steel building, mezzanine floor of “loft” 4 the force applied to the complex, special-shaped structure, building 5 used in-situ concrete structure(rc) buildings 6 used in the construction of slope roof structure Product advantages & features for lattice girders Advantages economy: the mode of truss is reasonable with low price and has an obvious advantage in this area; can be designed as double-sides deck. Convenient: shorten the project construction time; reduce temporaty support. Security: good performance of cracking resistance and fire resistance; Reliability: good property to prevent earthquake. (1)light in weight , high intensity, huge loading capacity as well as good anti-earthquake capacity. (2)simple in construction operation, easy to install. (3)can act as a part of the structure of weight bearing, to reduce the cost of material. (4)put the panel above the welded wire net fill cement between them. (5)this type of floor decking sheet has the strong friction between the concrete and floor slab, being fire resistant. (6)this deck is connected with steel bar , making it have the higher strength.
