Trench mesh reinforcement is welded by galvanized low carbon steel wire or high quality low carbon steel wire It divided the shape: trapezoid, triangle, two bars and three bars welding. The trench mesh reinforcement is always used on foundation construction, residential slabs, footing construction and pier beam. Specification of trench mesh reinforcement Surface treatment:galvanized or drawn wire Material: R250N, D500N, D500L, D300E, D500E The Tensile strength is 300Mpa. The trench mesh was produced by standard AS NZS 4671-2001 Width: 0.2m - 2.3m Length: 6m REINFORCING MESH TO AS/NZS4671: 2001 / TRENCH MESH Code STD UNIT LONGITUDINAL WIRES CROSS WIRES MASS / KG L8TM200 6 Metre 3 x 7.60 @ 100 4.00 @ 300 6.8 L8TM300 6 Metre 4 x 7.60 @ 100 4.00 @ 300 9.2 L8TM400 6 Metre 5 x 7.60 @ 100 4.00 @ 300 11.6 L8TM500 6 Metre 6 x 7.60 @ 100 4.00 @ 300 13.9 L8TM600 6 Metre 3 x 7.60 @ 100 4.00 @ 300 15.9 L8TM2400 6 Metre 25 x 7.60 @ 100 4.00 @ 300 72 L11TM200 6 Metre 3 x 10.70 @ 100 4.77 @ 300 13 L11TM300 6 Metre 4 x 10.70 @ 100 4.77 @ 300 17.7 L11TM400 6 Metre 5 x 10.70 @ 100 4.77 @ 300 22.3 L11TM500 6 Metre 6 x 10.70 @ 100 4.77 @ 300 26.8 L11TM600 6 Metre 7 x 10.70 @ 100 4.77 @ 300 34 L11TM2300 6 Metre 24 x 10.70 @ 100 4.77 @ 300 107.1 L12TM200 6 Metre 3 X 11.90 @ 100 4.77 @ 300 16.3 L12TM300 6 Metre 4 X 11.90 @ 100 4.77 @ 300 21.8 L12TM400 6 Metre 5 X 11.90 @ 100 4.77 @ 300 27.3 L12TM500 6 Metre 6 X 11.90 @ 100 4.77 @ 300 32.8 L12TM600 6 Metre 7 X 11.90 @ 100 4.77 @ 300 38.1 Trench mesh reinforcement for footing slab construction and Waffle rafts beam and piers And Alls of using is accordance to AS NZS 2870-2011. 1. Footing slap The reinforced footing: the preportions for the tied edge beam apply only where there is a structural connection by concrete-to-concrete contact tied with fitments. The trench mesh is used on bottom reinforcement. The site and the type of construction difference cause we select the specification of the trence mesh reinforcement is different. 2. Waffle rafts beam and piers The waffle rafts for a one-storey building for clad frame or masonry veneer on moderately or highly reactive sites may be supported on piers as follows without structural design of the waffle raft: (a). pier to be located on the intersection of every third internal beam. (b). An additional N12 bar at the top to be provided in the internal beams intersecting the piers, but no shear fitments are required.
