NON-STANDARD AND BENT WELDED WIRE MESH FOR CONCRETE REINFORCEMENT

NON- STANDARD AND BENT MESH FOR CONCRETE REINFORCEMENT
The production of mesh reinforcement complies to BS 4483. Mesh is produced from cold reduced deformed steel wires according to BS 4482.

Welded wire mesh can be produced to order in special sizes (Width, length, spacing, etc.) in order to suit the specific requirements of each project so that the maximum benefit is gained.

Welded wire mesh can be also bent into different shapes for the reinforcement of retaining walls, parapets, tube structures, manholes, box culverts and canals.

• Specified characteristic strength: 460 N/mm˛
• Tensile Strength: min 510 N/mm˛. In addition either the tensile strength recorded in the tensile test shall be at least 5% greater than the recorded yield strength or alternatively the minimum elongation shall be not less than 12% measured on a gauge length of 5do.
• Shear strength of the weld: The shearing load required to produce failure of a welded intersection shall be not less than 0.25 A fy, where A is the nominal cross-sectional area of the smaller wire at the welded intersection and fy is the characteristic yield stress of the wire (460 N/mm˛).

b) Chemical composition of steel

Carbon C: max 0.25%
Sulphur S: max 0.060%
Phosphorous P: max 0.060%
Carbon Equivalent Value Ceq: max 0.42%
Where Ceq = C + Mn/6 + (Cr+V+Mo)/5 + (Cu+Ni)/15
