What is A393 steel mesh?

A393 mesh is a welded steel mesh widely used in situations where concrete tensile strength needs to be enhanced. Both longitudinal and transverse reinforcements are 10 mm special-shaped steel bars; the bar diameter is H10, and the hole diameter is 200 mm x 200 mm. The “393” stands for the cross-sectional area per meter of width, which indicates the number of bars per meter of mesh width. This value is determined by the bar diameter and the mesh size. For example, the hole diameter of 252 mesh is the same as A393, but the bar diameter is 8 mm instead of 10 mm.

Key features and benefits

• High strength and rigidity: welded by cold-rolled ribbed steel bars or hot-rolled ribbed steel bars, it can withstand large loads and deformation.
• Strong crack resistance and impact resistance: the mesh structure can prevent concrete cracking and reduce surface cracking by about 75%.
• High construction efficiency: direct laying and pouring at the construction site, reducing the steel bar installation time by 50%-70%, greatly shortening the construction period.
• Good flexibility: providing a variety of standards such as 4.8m×2.4m, 3.6 m x 2.0 m, 2.4 m x 1.2 m, high mesh precision, suitable for different projects.
• Durability: surface treatment technology can improve corrosion resistance, better adapt to harsh environments, and extend the service life of the structure.
• Good economy: save steel bar usage, reduce comprehensive costs, reduce construction links, and improve project cost performance.

Wide range of applications

• Building structure reinforcement: used for the reinforcement of multi-storey/high-rise commercial buildings and residential floors and walls, and the overall welded mesh structure is used to enhance the crack resistance and bearing capacity of concrete.
• Infrastructure engineering: used in heavy-load high-frequency scenes such as airport runways, roads, tunnels, bridges, etc., relying on high strength to improve durability, resist complex forces and long-term wear.
• Pipelines and water conservancy facilities: as a reinforcing material for water conservancy projects such as concrete pipes, dams, and docks, it uses excellent anti-deformation ability to prevent the structure from cracking due to water pressure and settlement, and ensure long-term stability.
• Industrial and storage buildings: in industrial heavy-load environments such as factory floors and storage platforms, the steel mesh is combined with concrete to enhance impact resistance and wear resistance, and extend the life of high-frequency structures.
• Prefabricated component production: used for the manufacture of prefabricated wall panels, floor slabs and other components, improve the integrity and flexural strength of components, and adapt to standardized construction requirements.

Other common types

•  A142 mesh: Conforms to the British BS 4483 standard, with 6mm diameter steel bars and a large mesh size of 200×200mm. It is used for lightweight reinforcement in residential floors and pavements, offering low cost and ease of installation.
• A193 mesh: Conforms to the BS 4483 standard, with 7mm ribbed steel bars and a mesh size of 200×200mm. It offers higher strength than A142 and is suitable for medium-load applications such as industrial floors.
• A252 mesh: Conforms to the BS 4483 standard, with 8mm thick steel bars and a mesh size of 200×200mm. Designed for heavy-duty structures such as bridges and high-rise building slabs.
• D49 mesh: Conforms to the Chinese GB/T 1499.3 standard, with 6-8mm ribbed steel bars and a dense mesh size of 100×100mm. It offers high strength and earthquake resistance, and is widely used in domestic floor slabs and tunnel projects.
• A98 mesh: Conforms to the BS 4483 standard, with 5mm ultra-fine steel bars and a mesh size of 200×200mm. Designed for ultra-lightweight, non-load-bearing structures, such as decorative concrete layers.
• A192 Mesh: Conforms to BS 4483, with 6.5mm steel bars and a 100×200mm rectangular mesh. Optimized for unidirectional load bearing, suitable for foundations and industrial floors.
• C503 Mesh: Conforms to BS 4483, with 8mm steel bars and a 100×100mm dense mesh. Highly crack-resistant, suitable for dynamic loads such as airport runways.
• SL92 Mesh: Conforms to South African SANS 282, with 5.5mm steel bars and a 150×150mm mesh. Similar to A142, it is commonly used in lightweight construction in South Africa.

6 types of shaped steel mesh

• Type A: The spacing between steel bars is 200mm×200mm, which is suitable for coarse aggregate filling layers of large concrete structures such as foundations and dams.
• Type B: The spacing between steel bars is 100mm×200mm, which is suitable for bridges, tunnels and other projects that need to take into account both longitudinal load and lateral stability.
• Type C: The spacing between steel bars is 150mm×200mm, which is suitable for structures such as floor slabs and roofs that need to balance strength and economy.
• Type D: The spacing between steel bars is 100mm×100mm, which is suitable for high-precision concrete structures, such as precision equipment foundations or projects that require strict control of cracks.
• Type E: The spacing between steel bars is 150mm×150mm, which is suitable for medium-load walls, slope protection, and other projects.
• Type F: The spacing between steel bars is 100mm×150mm, which is suitable for structures with special design requirements, such as special-shaped cross-section components.

Technical Q&A

Q1: How to calculate the amount of A393 mesh?

Formula: Area (㎡) ÷ (2.4×6) = Number of pieces (calculated based on a width of 2.4m x a length of 6m). For example, a 500㎡ floor requires approximately 35 pieces.

Q2: What is the difference between it and A252 mesh?

The load-bearing capacity of A393 (10mm/200mm) is 30% higher than that of A252 (8mm/200mm), making it more suitable for heavy-duty floors.

Q3: What are the precautions for outdoor storage?

Three suggestions: Elevate the unit by 30cm to prevent moisture, cover the surface with a rainproof sheet, and use it within six months.
