Calculate weight Q424A structural steel mat
The weight of structural steel mats is given per square meter, as a mat reinforces one surface. The construction steel mat Q424A weighsapprox. 6.66 kg/m². A standard mat in the format 6.00 × 2.30 m (13.8 m²) weighs around 91.9 kg. For the quantity determination, multiply the area to be reinforced by the basis weight and plan a surcharge of 10-15% for overlap shots. Basics of this in the guideCalculate structural steel mats.

Structural mat Q424A according to DIN 488
The construction steel mat Q424A is a reinforcing steel mat according to DIN 488 made of cold-formed, ribbed reinforcing steel wire of the B500A type with a yield strength of 500 N/mm². The longitudinal and transverse rods are welded at the crossing points, creating a load-bearing, dimensionally stable reinforcement mat. Each mat is marked and comes with proof of conformity. The standard regulates varieties, dimensions, mesh sizes and test methods. Details explain the articlestructural steel mats according to DIN 488.
Q mats and R mats – difference
Construction steel mats are supplied as Q and R mats.Q matsWear in both directions the same (square reinforcement) and are suitable for two-axle slabs.R matsWear predominantly in the longitudinal direction and are used for single-axis clamped components. The construction steel mat Q424A belongs to the group of Q-mattens.
| Feature | Q mat | R mat |
|---|---|---|
| carrying direction | biaxial | uniaxial |
| cross bars | same diameter | thinner (distributor) |
| Use | slabs, floors | Single-axle components |
Applications of the Q424A structural steel mat
The construction steel mat Q424A is used in a reinforced concrete construction area – especially for:
- floor slabs and foundation slabs
- Reinforced concrete ceilings and element ceilings
- walls and basement walls
- Industrial floors and court areas
- Ramps, pedestals and strip foundations
The choice of the mat type and the mesh size results from the static calculation. The complete program can be found atstructural steel mats; matching bars underreinforcing steel.
Ver, overlap and concrete cover
Structural mats are laid with overlap: the mats overlap by at least one mesh plus length of the overlap so that the forces are transferred. Spacer secures the concrete cover according to Eurocode 2 – with the cross bars on top, the effective covering on the top must be observed. Binding wire fixes the mats in the formwork. For cuts and special shapes we supplySpecial and drawing mats.
Cut and special shapes
In addition to the standard Q424A storage mat, we deliver cut mats with cut-outs or as list and drawing mats according to your reinforcement plan. Factory assembled mats significantly reduce waste and laying time on the construction site. about theBending and cutting serviceGet made-to-measure reinforcement.
Quality, test certificate and delivery
The structural steel mat Q424A is supplied with a work certificate (acceptance test certificate 3.1) and proof of compliance – standard, testable and traceable. We deliver to Austria, Switzerland and Luxembourg on request. Bundles of mats are bulky and require crane discharge; We agree on a realistic delivery date in advance.

Sustainability and Efficiency
Structural mats save laying time compared to the single rod laying and are made of recycled steel and are even fully recyclable. The construction steel mat Q424A offers a favorable ratio of load capacity to processing effort at 4.24 cm²/m. If you plan the mat type, mesh size and overlap cleanly, you can reinforce areas quickly, in accordance with the standards and economically.
Application examples of the structural steel mat Q424A in detail
Base Plate:The construction steel mat Q424A takes on forced and payloads as a flat ground and reinforcement layer and limits cracks.Reinforced concrete ceiling:In the lower and upper reinforcement layers, the matt takes over field and supporting moments.Walls and basement walls:Laid on both sides, it ensures the distribution of the loads and the crack width detection.Industrial floors:In low-joint floors, the mat limits shrinkage and temperature cracks. Mats with spacers and support baskets are held in place for two-layer reinforcement.
Quantity determination for the structural steel mat Q424A
For calculation and order, the area to be reinforced is multiplied by the basis weight. Computing example for the construction steel mat Q424A: A base plate of 10.0 × 8.0 m = 80 m² requires around 6.66 kg/m² around533 kgSteel (without overlap). For single-layer reinforcement, this corresponds to about 6 standard mats (13.8 m²); For attacks, plan 10-15% additional quantity.
- Area × surface weight = steel weight
- Area ÷ 13.8 m² = number of standard mats
- Surcharge for overlap (10–15%)
- Consider waste at edges and recesses
Standards environment: DIN 488 and Eurocode 2
The construction steel mat Q424A is subject to the product standardDIN 488(concrete steel, reinforcing steel mats), while dimensioning and designEurocode 2 (DIN EN 1992-1-1)are regulated – these include concrete cover, overlap and minimum reinforcement. This ensures that the mat, laying and proof fit together and that the reinforcement is stable and durable.
Avoid common mistakes
- Too little overlap of the mats → Power transmission not secured
- Swapped Q and R mats → wrong direction of wear
- Too little concrete cover for lying cross bars
- Lack of support for the upper position → sink when concreting
- Forgot waste and assault in quantity determination
