Define the exact mesh configuration rather than ordering on a generic “steel mesh” description.
Welded reinforcement mesh is a grid of intersecting steel wires or reinforcing bars joined by resistance welds at designed intervals. It is supplied as mesh sheets, and certain smaller-wire products may be offered in rolls where the specified standard permits.
The combination of wire profile, diameter, pitch, sheet size and weld-joint quality determines the product purchased. Structural performance and placement must follow the approved concrete design.
Attach the approved drawings, wire schedule and quantities; we will check the proposed supply configuration.
Select the arrangement required by the approved reinforcement drawings.
Factory-made sheets for slabs, foundations, precast members and other specified concrete work. Dimensions and handling limits are agreed for each order.
Deformed reinforcement can be specified where bond and performance requirements call for it. Wire geometry and weld tests follow the selected material standard.
Different spacings, wire sizes and edge overhangs can be evaluated from project drawings. Custom manufacturing feasibility depends on equipment and order volume.
Specify both wire directions independently. “150 × 200” must identify which pitch runs across the sheet and which runs along it.
Typical dimensions shown are RFQ illustrations, not a guarantee that every variant is stocked or meets every national specification.

The wire surface and weld configuration must match the specified bond, ductility and test criteria.
Smooth round wire can form welded reinforcement where permitted by the project specification and product standard.
Surface deformations support concrete bond. Use the nominal cross-sectional area and grade defined by the specified standard.
State the longitudinal and transverse pitch separately, including direction on the fabrication drawing.
Specify applicable weld shear, tensile and inspection requirements with lot traceability.
For preliminary freight and purchasing budgets, use nominal wire geometry. Actual sheet mass depends on the exact wire counts, projections and specified tolerances.
| Long / cross diameter | Pitch (mm) | Approx. kg/m² | Approx. kg / 2.4 × 6 m sheet |
|---|---|---|---|
| Ø4 / Ø4 mm | 100 × 100 mm | 1.973 | 28.41 |
| Ø5 / Ø5 mm | 150 × 150 mm | 2.055 | 29.59 |
| Ø6 / Ø6 mm | 150 × 150 mm | 2.959 | 42.61 |
| Ø6 / Ø6 mm | 200 × 200 mm | 2.219 | 31.96 |
| Ø8 / Ø8 mm | 150 × 150 mm | 5.261 | 75.76 |
| Ø8 / Ø8 mm | 200 × 200 mm | 3.946 | 56.82 |
| Ø10 / Ø10 mm | 200 × 200 mm | 6.165 | 88.78 |
Joint verification is central to a reinforcement mesh order. Weld shear and other tests must follow the selected market standard.
Apply the required joint shear or weld test procedure and sampling plan for the specified product.
Review required yield/tensile values and ductility criteria for the actual grade and wire profile.
Inspect wire diameter / nominal area, centre spacing, sheet dimensions and edge projections.
Identify production batch or heat and inspection findings against the delivery documentation.
Consistent design intent depends on both grid directions and the correct geometry at sheet edges.
For example, Ø6 wire at 150 × 150 mm pitch creates a symmetric grid. It is a geometric illustration; supply and engineering suitability are checked against the contract.
Different spacing or wire size can be used in each direction where approved. Drawings should identify main reinforcement direction, transverse wire location and sheet orientation.
Specify reinforcement area, structural grade, lap and cover from approved engineering drawings.
Area reinforcement for structural slabs and approved slab-on-ground work.
Prefabricated reinforcement sheets installed to designed cover and lap details.
Mesh reinforcement where the pavement and movement-joint design specifies it.
Repeatable fabricated mesh layouts for panels, elements and production moulds.
Joint and load-transfer detailing carried out to the structural flooring design.
Sheet grid reinforcement with coordinated lifting, placement and edge arrangements.
Our company-wide resources support material procurement; individual mesh availability and testing are confirmed for each order.
Actual company-wide steel output across product categories. Mesh production arrangements are confirmed separately.
Regular combined inventory across the business, not a claim of on-hand stock for any particular mesh pattern.
Confirm the applicable standard, weld-joint testing, wire properties and material traceability before acceptance.
Review sheet stacking, bundle identification, loading constraints, packing lists and destination documents.
Calculate an approximate kg/m², sheet mass and total tonnage from longitudinal and transverse wire geometries.
Enter two wire diameters and pitches, finished sheet dimensions and the sheet quantity. This gives a theoretical steel mass estimate, excluding exact edge-wire counting and weld allowance.
Formula: nominal kg/m per direction = 0.006165 × d². Approx. kg/m² = 0.006165 × [d₁² × (1000/p₁) + d₂² × (1000/p₂)]. Crossings, edges and actual wire counts are not modeled.
For equal Ø6 mm wires spaced 200 × 200 mm in a 2.4 × 6.0 m sheet, the calculated theoretical mass is approximately 2.219 kg/m² or 31.959 kg per sheet. One hundred such sheets give about 3.196 metric tons before packaging.
Production route details and tooling capacity are confirmed for the requested product.
Any special mesh grade, weld spacing, twin-wire arrangement or non-standard sheet dimension is subject to technical confirmation.
Confirm production and stock status for the exact wire diameter, pitch and panel size rather than assuming a generic mesh inventory.
Provide a shipment schedule and we can assess grouped and phased supply options.
A useful mill certificate must match the actual supplied grade, production batch and standards agreed in the purchase order.
Offered services are evaluated by drawing, mesh configuration and planned quantity.
Packaging arrangements should protect the panel geometry, avoid uncontrolled movement and allow lot-by-lot receipt checks.
Share a wire schedule or design drawing to prevent mismatches between product codes and actual reinforcing area.
Submit the schedule once; we can return clarifications for each wire and panel pattern.
Mesh and straight reinforcing bars have different geometry, manufacturing and testing requirements. Any substitution needs design approval.
Clear responses to mesh sizing, standards, welded joint testing and procurement.
It is a sheet or, for certain approved configurations, a roll of steel wires or bars arranged at defined pitches and welded where they cross for use as concrete reinforcement.
Mesh is factory-welded into a predefined grid. Loose bars are individually placed and tied or joined to approved detailing. The engineer specifies which format is appropriate.
ASTM A1064/A1064M-24 covers plain and deformed carbon-steel wire and welded wire reinforcement for concrete; the purchase order should define the applicable product details.
BS 4483:2025 is the current British mesh specification and replaces BS 4483:2005. Confirm legacy-project edition requirements with the engineer.
Yes. GB/T 1499.3-2022 is the Chinese standard for steel welded fabric for concrete reinforcement, implemented in May 2023.
Those are useful example grid dimensions for a quotation. Confirm the actual wire sizes, grade, panel dimensions, line capability and availability for the requested schedule.
Structural application depends on the selected grade, mesh steel area, concrete design, support, placement, laps and cover. Use only the reinforcement approved by the project engineer.
For a preliminary estimate, add the nominal kg/m contributed by each perpendicular set of wires per square metre, then multiply by the sheet area and sheet count. Edge wires, projections and nominal mass tolerances change the actual result.
The design drawing should state longitudinal/cross wire diameter or area, spacing, grade, sheet length/width, edge projections and any lap or anchorage details.
Depending on the selected standard and contract: wire tensile and yield properties, weld shear or joint integrity, geometry, mass/section, grade identification and traceable batch records.
Non-standard pitch, dimensions and cut layouts can be reviewed from drawings. Production tooling, tolerances, testing and order volume determine feasibility.
Send the standard edition, strength grade, wire sizes, two pitches, panel dimensions, overhangs, order quantity, inspection requirements, destination and requested shipment terms.
Send your required grade, dimensions, quantity and destination. Our team will review the inquiry.
