We offers reinforcing concrete mesh. We cooperate with wholesale
and construction companies, owners of farms and suburban areas.
Welded mesh reinforcement bars are from 3 to 40 mm diameter,
located in mutually perpendicular direction and forming a square or
rectangular shape mesh. Reinforcing mesh opening size ranging from
50 mm to 250 mm. Distinguish heavy reinforcing mesh (diameter rods
of 12 mm and above) and light meshes (the diameter of the rods from
3 mm to 12 mm).
When choosing a wire mesh, material, mesh sheet size, mesh opening,
and the purpose must be taken into account. For example, if you
need concrete mesh for plastering, the thin wire mesh is suitable.
Wennian concrete reinforcing mesh specification:
- Materials: stainless steel rebar, galvanized steel rods.
- Diameter: 3 mm - 40 mm.
- Steel rods style: ribbed or smooth.
- Mesh opening shape: square or rectangular.
- Distance between rods 100, 200, 300, 400 and 500 mm.
- Mesh sheet width 0.65 m - 3.8 m, and length from 0.85 m, 6 m, 9 m,
12 m.
- Mesh sizes 6.0 m × 2.4 m, 4.80 m × 2.4 m, 3.6 m × 2 m, 2 m × 4 m.
The reinforcing steel mesh has become an integral component of
reinforced concrete structures and is used to enhance them.
1) Introductions of the galvanized welded wire mesh:
Welded wire mesh is galvanized before or after welding, having good
corrosive resistance and qualities which are not usually found in
average wire mesh.
Materials : Low carbon steel wire , black wire or galvanized wire,
stainless steel wire ect.
Processing: Galvanized after welding, Galvanized before welding
Finishing: Black, electro-galvanized before or after welding,
hot-dipped galvanized before or after welding, PVC coated
Features of our concrete reinforcing mesh
- The welded wire fabric makes them easier to work on.
- There are different diameters of steel reinforcing mesh each suited
for a particular application.
- There are different designs of steel reinforcing mesh from bent and
rolls to flat sheets.
- As per BS 4482 standards and codes, the stainless steel wire used
in the manufacture of the
steel reinforcing mesh has a 510MPa tensile strength and 485MPa
minimum proof stress. - The steel reinforcing mesh is rigid making it possible for you to
control concrete cover during
construction. - Manufacturers produce steel reinforcing mesh under SANS1024
Standard Specifications.
- The steel bars stay intact whenever immersed in concrete because
they are carefully welded
in mats. - You don’t have to apply additional surface treatment to the steel
reinforcing mesh before
use. - Less field labor needed when making reinforced concrete slabs using
this mesh thus
drastically speeding up the construction process. - The mesh is easy to load and unload, and easy to handle at the
working site.
- Properly mixed concrete is poured into the mesh and then given time
to dry out. The
concrete, as it continues to dry out, it grips the steel bars
tightly creating a bond stress
between these two materials. This bond stress is essential because
it reduces bending and
makes reinforced concrete slabs stronger.

Trench Mesh:
Trench mesh is long, narrow sheets of concrete reinforcing mesh,
ideally sizes for trenches, paths or other narrow spaces.
Trench mesh common uses include rock walls, brick walls and house
footings and used specifically for residential footing trenches.
Trench mesh made from grade D500L ribbed reinforcing wire including
main wire and cross wire. Its longitudinal wires (main wire) from
7.6 mm up to 15.6 mm diameter, and cross wire in 4 mm or 4.77 mm
diameter.
The trench rib mesh products all come 6.0 m longs with a variety of
standard widths from 200 mm to 500 mm.
