Our range of welded wire
mesh is supreme in quality, which is produced conforming to IS:
1566-1982 with long and cross wire spacing varying from 25 mm to 150
mm with 2 mm to 6 mm wire diameter. The intersections are rigidly
welded and each of them has the capacity to withstand the shear
stress up to 210 N\mm2 (IS: 4948-1974) on the reference area of the longitudinal wire. Our range is widely used in RCC-building
construction. It gives good reinforcement solution for industrialized
concrete constructions. Following are the advantages of the welded
wire mesh:
Higher
Characteristic Design Strength: The
welded wire mesh has a better characteristic strength point of view,
usage of welded mesh with Fe480 grade results in savings in steel
area or steel weight required to the tune of 13.55% vis-à-vis
HYSD bars of Fe 415 grade and to the tune of 47.92 % vis-à-vis
plain mild steel bars of Fe 250 grade.
Better
Bonding Behavior: The
bonding capacity of welded mesh is excellent. As against the
peripheral surface area which is responsible for bonding to concrete
in the case of individual bars, the rigid mechanical interconnections
by means of welds to cross wires are mainly responsible for stress
transfer from concrete to steel and vice-versa in the case of welded
mesh.
Better
and Economic Crack Resistance with Thinner Wires and Closer Spacing: The
welds have a strong mechanical anchorage behavior at each the
intersections are further responsible in imparting an immense deal of
homogeneity to the R.C.C section as a whole. The two dimensional uniform stress distribution of the welded mesh with the concrete
achieves better plate behavior in the slab. Further, welded mesh
usage affords the possibility of using thinner wires at closer
spacing. The close spacing of thinner wires and the two-way behavior
of welded mesh minimizes the crack widths and preserves structural
integrity of the slab.
Load
stresses in the residential slabs are low but where minimum thicknesses of 75 to 125mm are used from serviceability or other
reliability criteria. Following are some of the specifications of our

Savings
of Labor, Time and Binding Wire: This
consumption saved works out to about 2 to 5% of the reinforcement
used in terms of cost of steel saved. Besides, the added benefit is avoidance of those dangling ends of binding wire which are the
starting fuses for the virus of corrosion into the reinforcement.
