Welded steel wire mesh for concrete reinforcement is a structural mesh product fabricated from low-carbon steel wire (Q195/Q235 grade, aligned with ASTM A185 and EN 10080 construction standards) via automated electric resistance welding. It is purpose-built for concrete construction to control cracking, stabilize rebar positioning, and reduce on-site labor input.
Steel wires are cold-drawn to specified diameters, straightened, then welded at every intersection under calibrated pressure and current. This process creates uniform joints without wire fracture, forming a consistent grid that distributes concrete stress evenly across panels.
Parameter Category | Specification Range |
|---|---|
Mesh opening size | 5 mm × 5 mm - 100 mm × 100 mm |
Wire diameter | 0.5 mm - 6.0 mm |
Panel dimensions (width, length) | Customizable per customer requirements |
Surface treatment | Galvanizing, plastic coating, spray coating |
Each intersection is welded via automated equipment for consistent strength. For wire diameters of 2mm and above, weld points meet a minimum shear strength of 2.5kN, resisting separation during concrete pouring, vibration, and on-site handling under standard structural load conditions.
Production controls maintain tight manufacturing tolerances: ±0.05mm for wire diameter, and ±2mm for mesh openings across full panels. This consistency ensures even concrete coverage and predictable structural performance, reducing on-site adjustment work during installation.
Cold-drawn low-carbon steel delivers defined tensile strength aligned with concrete reinforcement requirements. The grid structure distributes shrinkage stress across concrete slabs, reducing curing-related shrinkage cracks. The wire surface resists abrasion during transport and placement, minimizing deformation before concrete pouring.
Three surface treatment options match different construction environments:
Electro-galvanized: Minimum 8μm zinc coating, suitable for indoor, dry concrete components
Hot-dip galvanized: 40g/m² to 60g/m² zinc coating, suitable for outdoor, high-moisture, and underground concrete works
PVC coated: 0.4mm to 0.6mm PVC layer over galvanized wire, suitable for coastal, high-corrosion construction zones
Panels can be cut and shaped on site with standard metalworking tools to fit irregular structural shapes. Pre-cut custom panels are available for commercial procurement orders to reduce on-site labor. Industry project data shows this mesh reduces rebar tying time by 30% to 50% compared to manually tied rebar grids for slab and foundation work.
Production runs on fully automated welding lines, with standardized workflows for wire drawing, straightening, welding, surface treatment, and cutting. Each production batch undergoes three mandatory inspections: wire diameter verification, mesh opening accuracy checks, and weld joint shear strength testing. For enterprise customers working on large construction projects, production schedules can be aligned with project timelines to support phased delivery. Batch inspection reports are available upon request to support construction supervision and acceptance processes. Packaging is designed for mechanical site loading and unloading to reduce transport damage.
Custom panels are produced within ±5mm length and width tolerance for standard orders. Tighter tolerance requirements can be discussed during the quotation stage for special project needs.
For coastal areas with high salt spray exposure, PVC-coated mesh over a hot-dip galvanized base is recommended to provide an additional barrier against chloride corrosion. Hot-dip galvanized mesh is suitable for general outdoor projects without heavy corrosive exposure.
Yes, mesh with 3mm to 6mm wire diameter and 100mm × 100mm to 200mm × 200mm openings is commonly specified for concrete road pavements to control thermal and shrinkage cracking. Final specifications should be matched to project engineering drawings.
Lead time ranges from 7 to 15 days for standard specification orders, depending on order volume. Custom specifications or large-volume project orders require additional production time, with exact timelines provided after order details are confirmed.
Yes, the mesh can be cut with standard rebar cutters or angle grinders on site to fit irregular structural shapes. Cut edges on galvanized or coated mesh can be treated with zinc-rich paint if required by project specifications.
