Welded wire mesh

Welded steel mesh grille are made ​​of welded rods of reinforcing steel, which are used for reinforcement ( reinforcement ) of planar reinforced concrete members, such as floor tiles, ceilings or walls. They are manufactured in quality controlled manufacturing plants industrially on a half - or fully automatic machines and consist of intersecting longitudinal and transverse bars of hot-rolled or cold-formed, ribbed reinforcing steel, the shear strength are connected at the intersections by resistance spot welding.

List of types of mesh

• Factory assembled bearing mats
• Lists and drawing mats that are produced needs basis according to the data of the orderer
• Stock mats are compared to standard mesh expanded, standardized rebar mats in different variants with single-plane shock
• Ironing mats for the production of three-dimensional reinforcement cages
• Roadway mats for reinforcement of concrete roads or concrete large surfaces, such as start and runways
• N- mats
• Sonderdyn mats for components with increased dynamic stress

All Matt species - with the exception of the N- mats, so Q- and R- mats - are in principle suitable for dynamic ( ie not predominantly static ) stress.

Welded mesh shall be marked in two ways with respect to their origin. On the one hand, the raw material must end with a roller indicator, the (formerly BSt 500 M) is rolled onto the rebar B500A or B500B be provided even be attached to another you have to the mat a weather-resistant label stating that in which the factory this mat was welded.

Are standardized Betonstahlmatten in DIN 488-4. According to the definitions of the DIN standard rebar mats are made ​​of ribbed bars with a nominal diameter 6 to 14 mm and are in accordance with DIN 1045-1, Table 11 corresponding to the input material used to be classified as normal or high ductility. Only highly ductile B500B starting material may be used for the nominal diameter of 14 mm.

It may hochgeripptes for the production of welded mesh starting material B500A and B500B and B500A tiefgeripptes starting material can be used.

Welded mesh with wire diameters ≤ 6 mm shall be in accordance with DIN 1045-1 and DIN 488-4:2009-08 no longer used for static purposes and used for the calculation according to DIN 1045-1.

The name for mats is Betonstahlmatten B500A or B500B (formerly BSt 500 M).

Due to the DIN 488 prescribed mechanical values

• Yield point 500 N / mm ²
• Tensile strength 550 N / mm ²
• Yield ratio at normal ductility 1.05, at high ductility 1.08
• Total elongation at maximum load at normal ductility min. 2.5%, with high ductility min. 5%
