ÖMAT meshes

ÖMAT electrowelded meshes are used as prefabricated reinforcements. They are industrially welded in compliance with the ÖNORM B4707 standard with longitudinally and transversally ribbed wires. Owing to their mechanical and technological characteristics, ÖMAT meshes are classified as B550A meshes according to the ÖNORM B4707 standard.

The main feature of these electrowelded meshes is the presence of hooks on longitudinal edges.

Yield strenght

Re ≥ 550c N/mm²

Ratio / Yield strenght

Rm/Re ≥ 1.05c

Total elongation

Agt ≥ 2.5c %

For Diameter of 5.0 mm to5.5 mm applies:

Rm/Re ≥ 1.03c

Agt ≥ 2c %

For diameters less than 5.0 mm, no evidence is required.

Length: 6.00 m standard
Width: 2.40 m standard

Special lengths: 5.10 m / 7.20 m for AS 90, AS 100, CQS 70, CQS 80, CQS 90, AQS 90, AQS 100

Other special lengths upon request.

Advantages of ÖMAT electrowelded meshes:

  • The special overlapping system with hooks makes laying simpler and ensures quick and safe site control.
  • Reduced use of steel in overlapping areas thanks to single overlaps with hooks of just 20 cm.
  • Lower weight thanks to lighter edges.
  • Increased profitability thanks to the availability of 2 standard lengths of 5.10 m/6.00 m/7.20 m, respectively, for meshes type AS, CQS and AQS.
  • Simple and safe handling of meshes thanks to the presence of hooks.

Longitudinal overlapping/transversal overlapping

34 cm / 34 cm (zB. Beton B25) 42 cm / 20 cm (Schlaufenstoss)

1 mesh panel covers a surface of

(6.00-0.34)*(2.40-0.34)=11.66 m²

(7.20-0.42)*(2.40-0.20)=14.92 m²

Average steel requirement

5.20*6.00*2.40/11.66=6.42 kg/m²

5.24*7.20*52.40/14.92=6.07 kg/m²

Laying method 1:
Overlapping s1: 20 cm

Laying method 2:
Overlapping s2= 40 cm

The choice between method 1 or 2 depends upon the mesh cross-section and the way it is cut taking into account economic criteria.
