What is mesh A393?
What is mesh A393?
A393 2.4m x 4.8m (Standard Size) Reinforcement Mesh Fabric A393 mesh is most commonly used in heavier duty industrial concreting in walls and floor slabs with a thickness or depth of at least 200mm. 10mm wires are spaced to create 200mm apertures, and each standard size sheet weighs approximately 70.9Kgs.
How is BRC mesh calculated?
Firstly, you need to calculate the area of your concrete slab. To do this simply multiply the length of the slab by the width. Now that you have your area calculation, you need to divide the area by 12.5. This will give you the number of steel mesh sheets required to reinforce your concrete slab.
What is the weight of A393 mesh per m2?
6.16
Standard sheet size 4.8m long x 2.4m wide, giving a sheet area of 11.52m2
| Type BS Reference | Mesh Sizes Nominal Pitch of Wires | Weight Per m² |

| A393 | 200 | 6.16 |
| A252 | 200 | 3.95 |
| A193 | 200 | 3.02 |
What is yield strength of steel reinforcement?
Steel reinforcement is available with yield strengths from 40 to 100 ksi. The yield strength of steel is not dependent on the bar diameter and substitution of different combinations of bars with the same bar area may be readily provided.
What is A393 mesh used for?
A393 Reinforcing Mesh is used to help concrete withstand tension force. Although the concrete is strong enough by nature to withstand compression force, it can also crack from load bending tensile force. Therefore, it needs help resisting the tensile stress, using high tensile substance.
How is BRC Reinforcement calculated?
How to Estimate Concrete Reinforcement Mesh
- area = length × width.
- mesh needed = slab area ÷ mesh area.
- lapping percentage = overlap ÷ reinforcement width.
What is yield strength formula?
The point of intersection of the new line and the stressstrain curve is projected to the stress axis. The stress value, in pounds per square inch, is the yield strength. For example, “Yield Strength (at <0.2% offset) = 51,200 psi.”
What is yield strength ratio?
The yield to tensile ratio of a line pipe material is a measure of the margin of safety against failure by plastic collapse, and indicates the ability of a pipe to experience plastic deformation before failure.
How do you calculate mesh?
Figuring out the mesh number is simple. All you do is count the number of openings in one linear inch of screen. This count is the mesh number. A 4-mesh screen means there are four little square openings across one inch of screen.
What does A393 steel reinforcement mesh do for concrete?
A393 Reinforcing Mesh is used to help concrete withstand tension force. Although the concrete is strong enough by nature to withstand compression force, it can also crack from load bending tensile force. Therefore, it needs help resisting the tensile stress, using high tensile substance.
How big is a standard mesh reinforcement mesh?
A393 Reinforcement Mesh. A393 Reinforcement Mesh. In stock. SKU. RM-393-STD. £67.28. 14 Sheets per tonne. 2.4m x 4.8m (Standard Size)
What are the mechanical properties of steel bar mesh?
Mechanical Properties of Steel Bar Reinforcing Mesh: * Tensile Strength: min 510 N/mm2. In addition either the tensile strength recorded in the tensile test shall be at least 5% greater than the recorded yield strength or alternatively the minimum elongation shall be not less than 12% measured on a gauge length of 5do.
Why are lapping meshes staggered in Eurocode 2?
Eurocode 2 suggests the reinforcement lapping to be staggered so as not to create a large zone of discontinuity that could potentially lead to member failure.
