Product Overview

Wire nets are fabricated from drawn steel wire arranged in a regular grid of parallel and perpendicular strands. The mechanical performance depends on wire diameter, mesh aperture, and tensile strength of the base material.

Typical specifications include wire diameters ranging from 0.8 mm to 5.0 mm, mesh openings from 5 mm × 5 mm to 100 mm × 100 mm, and tensile strengths up to 600 MPa for low‑carbon steel.

Material Options

Base wire can be supplied in several grades, each influencing corrosion resistance, formability, and cost.

• Low‑carbon steel (C ≤ 0.25 %) – good weldability, tensile strength 350–450 MPa.
• Galvanized steel (Zn coating 20–80 g/m²) – improves atmospheric corrosion resistance.
• Stainless steel (AISI 304 or 316) – chromium content ≥18 %, nickel ≥8 %, suitable for acidic or saline environments.
• PVC‑coated wire – polymer layer thickness 0.2–0.5 mm for added abrasion resistance.

Manufacturing Process

The production line consists of wire drawing, straightening, welding (or weaving), and finishing. Each step is controlled to maintain dimensional tolerances.

Wire drawing reduces diameter to the target size while increasing tensile strength via work hardening. Straightening removes residual curvature to ensure flatness.

For welded mesh, resistance spot welding fuses intersecting wires at programmable pressure and time, achieving weld shear strength typically 70 % of the base wire tensile strength.

Woven mesh is produced on looms where warp and weft wires are interlaced; the resulting aperture tolerance is ±0.5 mm for meshes ≤25 mm.

Customization Choices

Customers can specify geometry, coating, and edge treatment to match application requirements.

• Mesh aperture: customizable from 3 mm to 150 mm in both directions.
• Wire diameter: selectable in 0.1 mm increments within the available range.
• Panel size: standard widths 0.5 m, 1.0 m, 1.5 m; lengths up to 6 m, or custom cut to length.
• Edge treatment: folded, welded, or fitted with PVC edge guard.
• Surface finish: bare, galvanized, powder‑coated (RAL colors), or PVC‑coated.

Typical Applications

Wire nets serve functions where load distribution, containment, or filtration is required. The choice of aperture and wire size determines suitability.

• Concrete reinforcement – apertures 25 mm–50 mm, wire 2.0 mm–4.0 mm, providing shear crack control.
• Insect screening – apertures 1.0 mm–2.0 mm, fine wire 0.8 mm–1.2 mm, often PVC‑coated for durability.
• Security fencing – apertures 50 mm–100 mm, wire 3.0 mm–5.0 mm, galvanized for outdoor exposure.
• Filtration and sieving – apertures 0.5 mm–5.0 mm, stainless steel 304 for chemical resistance.
• Agricultural trellis – apertures 75 mm×75 mm, wire 2.5 mm, UV‑stabilized coating.

Quality Control

Inspection focuses on dimensional accuracy, weld integrity, and coating uniformity.

• Aperture measurement using calibrated laser gauges, tolerance ±0.2 mm for ≤25 mm mesh.
• Wire diameter checked with micrometers, tolerance ±0.01 mm.
• Weld shear strength tested per ISO 15614‑1, acceptance ≥60 % of base wire tensile.
• Coating thickness measured by magnetic induction, galvanized ≥20 g/m², PVC ≥0.2 mm.
• Visual inspection for surface defects, wire breaks, or misaligned strands.

Packaging and Shipping

Finished rolls or flat panels are protected to prevent deformation and corrosion during transit.

• Rolls: wound on cardboard cores, inner diameter 150 mm, outer wrap polyethylene film.
• Flat panels: stacked, edge‑protected with corrugated cardboard, strapped with PET bands.
• Moisture barrier: silica gel packets or VCI film for galvanized and stainless steel.
• Labeling: includes part number, wire diameter, aperture, coating type, and quantity.

Frequently Asked Questions

Can dimensions be customized?

Yes. Wire diameter, mesh aperture, panel width and length are all adjustable to project specifications. Provide a drawing or detailed requirements for a quote.

What information is required before quotation?

Required data includes: wire material (steel grade or coating), desired wire diameter, mesh opening size, panel dimensions, quantity, and any special edge treatment or surface finish.

Which materials are available?

Low‑carbon steel, galvanized steel, stainless steel (AISI 304/316), and PVC‑coated wire. Other alloys can be sourced upon request.

How is quality inspected?

Inspection includes aperture and wire diameter measurement, weld shear testing, coating thickness verification, and visual defect screening. Reports are available with each shipment.

What packaging methods are available?

Rolls on cardboard cores with PE film wrap, or flat panels stacked with edge protection and PET strapping. Moisture‑barrier options include VCI film or silica gel.

How are export shipments protected?

Cartons are palletized, stretch‑wrapped, and fitted with corner guards. For sea freight, additional waterproof lining and desiccants are added.

What is the typical production lead time?

Lead time varies with complexity but generally ranges from 10 to 25 working days after receipt of confirmed specifications and deposit.

How are samples arranged?

Sample pieces (up to 1 m²) can be produced within 3 working days. Shipping costs are borne by the requester; sample fees are credited against a subsequent order.
