A252 Mesh

A252 mesh is a type of steel mesh made by welding low-carbon steel wires. The mesh is square-shaped and has the characteristics of high tensile strength, corrosion resistance, durability, and convenient construction. It is commonly used in concrete projects such as ground reinforcement, floor slabs, and road paving. When combined with the high tensile strength of concrete, it enhances the concrete structure and reduces cracking. Wanzhi Steel specializes in producing A252 mesh. In addition, we also have commonly used steel mesh such as A393 and A193, which are supplied at factory prices. If you are interested, please feel free to contact us.

Character definition

Simply put, a252 mesh refers to a welded steel mesh with a weight of 5.95 kilograms per square meter, a nominal diameter of 8 millimeters, and a mesh spacing of 200mm x 200mm.

• A “: A mesh made of welded A-grade steel bars that comply with BS 4483 standard.
• 252 “: represents the nominal cross-sectional area of each linear meter of steel reinforcement, measured in square millimeters (mm ²).

Key Features

• Material and Structure: Made of low-carbon steel wire or cold-rolled ribbed steel bars welded together, with longitudinal and transverse steel bars welded at right angles to form a stable grid.
• High tensile strength: The material properties endow it with excellent tensile performance, which can withstand large tensile forces without easily breaking.
• Corrosion resistant and durable: Low carbon steel wire material has a certain degree of corrosion resistance, and the A252 mesh after galvanizing is capable of withstanding humid or corrosive environments, extending its service life.
• Convenient construction: Prefabricated production, direct on-site laying, eliminating the traditional steel bar binding process, greatly improving construction efficiency.
• Enhanced concrete performance: After being combined with concrete, it can effectively disperse stress, reduce the risk of cracking, and improve overall stability and seismic resistance.

Application

1. Housing and Construction

In housing construction, A252 steel mesh is used in concrete floor slabs, roof panels, and paving. As the primary load-bearing and distribution reinforcement, it effectively controls thermal and shrinkage cracks, preventing uneven settlement.

2. Road and Bridge Construction

It is used in cement concrete surfaces on highways and urban roads, and in bridge pavements. It strengthens and distributes loads, improving the impact and fatigue resistance of the pavement, thereby extending the service life of the contact surface.

3. Foundations and Public Facilities

It is used in large foundation slabs, tunnel linings, canals, reservoir structures, municipal pipeline corridors, airport runways, and port yards. The reliable steel skeleton enhances structural integrity and impermeability, meeting high demands for durability and stability.

Production Process

3. Resistance Welding

The resistance welder uses electric current and pressure to instantly melt the contact surfaces at the intersections, completing the welds at all nodes. Wanzhi Steel ensures a strong and uniform weld with no false welds or weld-throughs.

4. Cutting to Length and Stacking

The welded, infinite-length mesh is cut to the desired length by a hydraulic device. The finished mesh is then conveyed via a conveyor roller and neatly stacked by an automatic stacker.

5. Quality Inspection and Shipment

Qualification inspectors randomly check the mesh size, weld strength, and rebar specifications. If qualified, the mesh is secured with steel straps and packaged. Labels indicate the model and batch information.

FAQs

1. What does A252 mean?

A: “A” stands for standard square welded steel mesh. “252” is a model code, indicating, according to BS 4483, that the mesh has a cross-sectional area of ​​252 square millimeters per meter of width. The standard fixed mesh spacing is 200mm x 200mm.

2. Is the diameter of A252 steel mesh fixed?

A: No. The model “A252” only specifies the spacing and total cross-sectional area; the bar diameter must be specified separately. Commonly available diameters include 7mm and 8mm. For example, “A252 diameter 8mm” is a complete specification.

3. What is the difference between A252 and A193, and A393?

A: The main differences lie in the spacing and density of the bars:

• A193: The densest spacing (100mm x 100mm) is used in areas requiring high crack resistance.
• A252: With medium spacing (200mm x 200mm), it’s the most common type for floors and exterior walls.
• A393: With a wider spacing (200mm x 200mm), it uses thicker bars and has a higher load-bearing capacity.

4. What projects is A252 primarily used for?

A: It’s widely used, including: Residential construction: concrete floors, slabs, roofs, and walls. Road and bridge construction: cement concrete pavements and bridge decks. Public facilities: foundation slabs, small reservoirs, canals, etc.

5. Is it supplied in sheets or rolls?

A: It’s primarily supplied in standard sheets (e.g., 4800mm x 2400mm) for easier on-site handling and installation. Rolls are occasionally available.

6. How do I calculate the weight per square meter of A252?

A: The weight depends on the diameter of the bars. A simplified estimation formula is: Weight per square meter (kg/m²) ≈ Rebar diameter (mm)² × 0.00617 × 10. For example, for A252 mesh with a diameter of 7mm: 7² × 0.00617 × 10 ≈ 3.02 kg/m².

7. What information do I need to specify when purchasing A252?

A: The following information must be specified: Full model number: A252, Rebar diameter: e.g., 7mm, Sheet size: e.g., 4800mm x 2400mm, Material standard: e.g., BS 4483, Surface treatment: e.g., Plain steel, Galvanized (if required).
