STEEL GRADE FROM 485 MPA TO 550 MPA - Numesh

1 ENGINEERED WELDED WIRE REINFORCEMENT (EWWR). DESIGN TABLES. STEEL GRADE FROM 485 MPA TO 550 MPA. IMPERIAL SPACING / METRIC SPACING / Numesh IS MUCH MORE. THAN WIRE MESH! FAST DELIVERY. CUSTOM MADE PRODUCTS. TECHNICAL SUPPORT. 2. CRITERIA FOR DESIGNING CONCRETE PRODUCTS WITH. ENGINEERED WELDED WIRE REINFORCEMENT (EWWR). If 10M, 15M, 20M rebar content : evaluate your design in 485 MPa, 515 MPa , 500 MPa or 550 MPa vs 400 MPa to reduce STEEL content to an equivalent resistance. Design the welded wire reinforcement having STEEL sections with a common denominator ; then add bars if needed in some areas. Walls, Slabs, Beams, Columns: square or rectangular shapes wire mesh. Repetition of same WWR model and few tons per model The most popular wire sizes for the design of WWR are: D3, D4, , D5, D7, D8, D9, D10, D11, D12, D14, , D16, D18, D20 and D31. Design in WWR with a maximum of 4 different diameters, as suggested in the table of equivalences below: TABLE OF EQUIVALENCES OF 10M AND 15M REBAR FOR FABRICATION OF WELDED.
