Wholesale 3D Curved Welded Wire Mesh Fence Panels

The panels are fabricated from cold‑drawn steel wire with a typical diameter of 3.0 mm to 5.0 mm. Weld points are created using resistance welding, achieving a shear strength of at least 80 % of the wire’s tensile strength. After welding, the mesh is bent along a predefined radius to produce a three‑dimensional curve that adds moment of inertia and improves resistance to lateral forces.

Typical Applications

Industrial perimeter security where impact resistance is required, such as around machinery yards or storage facilities.
Highway glare screens and median barriers where the curved geometry reduces wind‑induced vibration.
Agricultural enclosures for livestock, providing a smooth surface that limits animal injury while maintaining structural rigidity.
Temporary construction site fencing that needs quick installation and resistance to accidental impacts from equipment.

Manufacturing Overview

Wire is first drawn to the target diameter and cleaned to remove oxides. It is then fed into a resistance welding machine where overlapping wires are fused at programmed intervals. The welded sheet is transferred to a forming press equipped with radius‑specific dies; the mesh is bent uniformly along the longitudinal axis to achieve the designed curvature. Finally, the panel passes through a hot‑dip galvanizing line or a PVC coating station, depending on the corrosion protection level specified by the customer.

Quality Control Procedures

Each batch undergoes visual inspection for weld consistency and coating uniformity. Dimensional checks are performed using laser scanners to verify panel width, height, and curvature radius within ±2 mm. Tensile samples are cut from the wire and tested to confirm minimum yield strength of 350 MPa. Adhesion of the galvanized layer is assessed by a standard bend test; coating thickness is measured with a magnetic gauge at five points per panel.

Customization Choices

Wire diameter: 2.5 mm to 6.0 mm, selectable in 0.5 mm increments.
Mesh opening: rectangular or square, ranging from 25 mm × 25 mm to 100 mm × 100 mm.
Curvature radius: adjustable from 100 mm to 400 mm to match specific load requirements.
Panel length: modular sections from 500 mm to 3000 mm, with interlocking edges for seamless assembly.
Surface finish: hot‑dip galvanized, galvanized‑plus‑polymer coating, or powder‑coated in RAL colors.

Frequently Asked Questions

Can the panel dimensions be customized? Yes, width, height, wire gauge, mesh size and curvature radius are adjusted according to project specifications.
What information is needed for a quotation? Required details include total linear meters, desired height, wire diameter, mesh opening, coating type, and any special end‑post or gate requirements.
How is quality verified before shipment? Each panel undergoes dimensional inspection, weld strength sampling, and coating thickness measurement; a test report is available upon request.
What packaging methods protect the curved panels? Panels are stacked flat with protective corrugated sheets between layers, then strapped and placed in wooden crates or steel frames to prevent deformation during transit.
What is the typical production lead time? For standard specifications, lead time is 2‑3 weeks after receipt of confirmed purchase order; custom sizes may extend to 4‑5 weeks.
