Our wire nails are used is in various settings and purposes, ranging from commercial to residential and infrastructure construction, household uses, assembly of wooden pallets, for wooden houses and slab form work. As the only manufacturer who produces both plain and indented BRC welded wire mesh in Sri Lanka, complying with BS 4483:2005, Sonic BRC Welded Wire Mesh offer better strength, integration and crack resistance compared with other wire mesh products. They are manufactured from plain and indented wires that are welded together using pneumatic welding machines. Providing better anchorage and crack control, our pneumatic welding machines assures uniform spacing of wires and consistent cross sectional areas without loss of strength and dimension.

Sonic BRC mesh provides the perfect quality, conforming to industry standards and is made from 6mm and 8mm wires with the welded bond at intersections (without reducing tensile strength of wire). It boasts of shear strength of 80% of the mesh yield strength, which is 540 Mpa, compared to manually fabricated mesh which only has the strength of 300Mpa.

Our ribbed mesh also guarantees to increase the bond characteristic of steel (by approx. 40% higher than plain bar reinforcement).

Applications of B.R.C Mesh

Wire mesh is mainly used in the building construction industry.

Its key applications and usage embed its ability to act as a preventive cover against cracks on slabs & ground floor, strengthen and holds retaining walls, provides strength for culverts, retention of damn or reservoir walls and in precast products.
