A393 Reinforcement Mesh 4.8Mtr x 2.4Mtr x 10mm Dia Bar

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.

With competitive price and timely delivery, Heyou sincerely hope to be your supplier and partner.

10mm wires are spaced to create 200mm apertures, and each standard-size sheet weighs approximately 70.9 kg.

Sheets are available 'off the rack' in these sizes:

1.2m x 2.4m Sheets
3.6m x 2.0m Merchant Size
4.8m x 2.4m Standard Size

We maintain high stock levels of all concrete reinforcement mesh and can provide priority delivery to your home, site, or premises if required.

Positioning the mesh fabric within a slab is vital. So, plastic gripper-grade plate spacers or other steel or concrete positioning structures are imperative. When using multiple sheets over a large area, ensure that all sheets overlap by at least 600mm, and are tied together using recommended methods.

A393 Mesh FAQs

What is A393 mesh?

A393 mesh is an essential component in concrete reinforcement, comprising a grid of steel wires that significantly enhance the structural integrity and tensile strength of concrete. Its primary function is to distribute loads and resist cracking, making it indispensable for concrete slabs, pavements, and various other constructions.

What does A393 mesh mean?

The designation "A393" in A393 mesh signifies a specific type of steel reinforcement mesh commonly used in construction. The "A" represents that it is designed for use in construction applications, while the number "393" refers to the nominal size and weight characteristics of the mesh.

What thickness is A393 mesh?

The thickness of A393 mesh is a crucial aspect of its design, ensuring it can provide the necessary support for concrete structures. Each wire in the mesh has a diameter of 10mm, contributing to its robustness and effectiveness in reinforcing concrete.

How many m2 is a sheet of A393 mesh?

A standard sheet of A393 mesh measures 4.8 metres by 2.4 metres, offering a substantial coverage area of approximately 11.52 square metres. These dimensions are specifically designed to cover large sections of concrete surfaces efficiently, minimising the need for multiple sheets and thereby reducing potential weak spots.

A393 Reinforcement mesh is used in the construction of heavy-duty concrete slabs for roadways and car parks where heavy use is expected, either in single or double layers of reinforcement. The mesh fabric is also used for walls and slabs in concrete flooring. When encased in concrete, mesh greatly increases the rigidity and strength of the structure. As the coefficient of thermal expansion is similar in both steel and concrete, a steel mesh reinforced concrete slab or wall expands and contracts at a comparable rate, therefore temperature fluctuations will not cause cracking of the concrete. Reinforcing steel is very strong in tension and concrete is strong in compression, by combining these two materials a very durable building structure is created. Steel reinforcement mesh is frequently specified by a qualified structural engineer.

A393 is available from stock in ECO, Flying End (2.4 x 4.8M) and Merchant size (3.6m x 2.0m) sheets for easier transport and handling on site.

ECO Mesh offers an increased efficiency engineered solution for reinforced concrete floors by saving a reinforcement wire on each lap of the mesh sheet. ECO mesh has the same centres as standard fabric mesh with the exception of the external overhangs which are 200mm compared to 100mm.

Genius Hints Always have sufficient concrete covering for the mesh, both above, below and around. Mesh should be supported from below at regular intervals by Continuous Hystools, Circular Wire Spacers, Concrete Bar Spacers or Plate Spacers which are made for this purpose. Lemon carries a large stock of these and many more accessories and can deliver to site along with your reinforcement on one of our specialist crane offload lorries.

Standardised mesh fabric is defined in British Standard denominations (such as A193, or B785). These numbers refer to the cross-sectional areas of the mesh per metre squared. So with A193 mesh for example, there is 193mm2 of steel in each 1m (mm) width of mesh.

All reinforcing mesh is manufactured to BS/ with CARES certification. Please visit our downloads section for Lemon CARES approval certificates.
