China Rolls Of Welded Wire Mesh Factory

Welded wire mesh rolls are produced by intersecting longitudinal and transverse wires at right angles and fusing each intersection with resistance welding. The resulting grid provides uniform opening dimensions and consistent tensile performance across the entire roll length, making it suitable for continuous feeding into downstream processes such as concrete placement or fence fabrication.

Material Composition

The base wire is typically low‑carbon steel grades such as Q195 or Q235, chosen for their balance of ductility and weldability. For corrosion resistance, the wire may be hot‑dip galvanized to a coating weight of 60‑120 g/m², or alternatively coated with a PVC extrusion layer of 0.5 mm thickness when chemical exposure is expected.

Manufacturing Process

Wire is drawn to the target diameter, straightened, and fed into a dual‑axis welding machine where longitudinal wires are held under controlled tension while transverse wires are dropped and spot‑welded at each cross‑point. Line speeds typically range from 15 m/min to 40 m/min, with real‑time monitoring of weld nugget size to ensure consistent fusion without overheating the base metal.

Quality Assurance

Each roll undergoes tensile testing of a sample strip to verify that the ultimate tensile strength meets the specification of the base wire grade (e.g., ≥ 350 MPa for Q235). Weld shear strength is measured using a pull‑off test, targeting a minimum of 80 % of the parent wire strength. Coating adhesion is assessed by a bend test where the coated wire is bent over a mandrel diameter equal to twice the wire diameter; no cracking or flaking is permitted.

Applications

In concrete construction, the mesh serves as a primary reinforcement layer for slabs and walls, distributing loads and controlling crack formation due to its uniform aperture and continuous length. For perimeter security, the same product is cut to height and installed as a fence panel; the welded joints provide resistance to impact and tampering compared with woven alternatives. Agricultural facilities use the mesh for animal enclosures because the smooth welded surface reduces injury risk while maintaining structural integrity under livestock pressure.

Customization Options

• Roll width adjustable from 0.5 m to 2.5 m
• Wire diameter selectable between 1.2 mm and 5.0 mm
• Aperture patterns: square 25 mm–150 mm, rectangular 25 mm×50 mm up to 100 mm×200 mm
• Coating choices: hot‑dip galvanized (60‑120 g/m²), PVC‑coated (0.5 mm), or stainless‑steel wire (grade 304/316)
• Length customization from 20 m to 150 m with optional center‑core reinforcement

Packaging and Logistics

Rolls are wound onto a steel or wooden core with an inner diameter of 50 mm to facilitate handling with standard roll lifts. The exterior is wrapped in UV‑stabilized polyethylene film, then secured with polypropylene straps placed at 0.5 m intervals. Palletized shipments use heat‑treated wooden pallets conforming to ISPM‑15, with a maximum stack height of two rolls to prevent deformation during transit.
