Reinforcement networks have a very wide application in construction: in high-rise construction (foundations, slabs, walls, stairs), in civil engineering (roads, bridges, retaining walls, tunnels), hydraulic (dams, canals, collectors), for the manufacture of various types of reinforced concrete elements and more.
Dimensions of the net:
- a – axial distance of longitudinal wires (mm) a = 100+25n, n= 0,1…..8 mm
- t – the axial distance of the transverse wires (mm) t = 50+25n, n= 0,1…..14 mm
- condition: t < 3a i ( a+t ) < 400 mm
- L – length of the net (mm) 2,5 < L < 8,0 m
- B – net width (mm) 1,5 < B < 2,45 m
- D – diameter of longitudinal wires (mm)
- d – the diameter of the transverse wires (mm) 1,5 > d/D > 0,51
- X1, X2 – indentation of longitudinal wires (mm) X1 = X2 = t/2 > 50 mm
- Y1, Y2 – culvert of the transverse wires (mm) Y1 = Y2 = a/2 > 25 mm
The product range includes numerous combinations of longitudinal and transverse wires and their distances between them and can be:
- transversely load-bearing, T – grids, the wires are crossed in the shape of a rectangle (a > t), whereby the transverse wires are supported
- mutually wearable, Q – nets, the wires are crossed in the form of a square (a=t), and the longitudinal and transverse wires are supported
- nets for vertical wall construction, Qx – The net is identical to the Q network, except that the passes on one side are much longer than those on the other, and they are defined according to specific needs.
- special net on special order, S – mreže
Tolerances allowed
The production, delivery and quality control of a welded reinforcement mesh is prescribed by the standard U.M1.090.
The quality control of the cutting rods is performed by testing the mesh for: tensioning according to the standard EN10002-1and bending to standard C.A4.005.Transverse load-bearing, T-nets

Reinforcement mounts, binor
Reinforcing bars – binor are made of cold drawn wire (smooth or ribbed) that meets the mechanical characteristics prescribed by the standard SRPS C.B6.013. Depending on the type of bracket, there are two and four bars, respectively, in the lower belt, one in the upper belt and interconnected by bent diagonal bars that are welded electrically to the upper and lower belts. They are used in construction mainly for floor and roof structures in high-rise buildings, such as for example. residential buildings, industrial halls, public buildings (hospitals, schools, etc.).
Product Specifications:
Chemical and mechanical properties are up to standard C.B6.013
stretching limit min. Re = 500 N/mm2
