How to Read Welded Wire Mesh Sizes and Specifications

Understanding welded wire mesh sizes and specifications is essential when selecting mesh for construction, fencing, or industrial use.
Incorrect interpretation can lead to wrong material selection, higher costs, or project delays.

This guide explains how to read welded wire mesh specifications clearly and correctly.

What Do Welded Wire Mesh Specifications Mean?

Welded wire mesh specifications describe the wire diameter, wire spacing, and panel or roll size.

These values define the strength, stiffness, and application of the mesh.

Most specifications follow a standard order:
Wire diameter × wire spacing × panel size

1. Wire Diameter

Wire diameter is usually expressed in millimeters (mm).

Common wire diameters include:

3 mm

4 mm

5 mm

6 mm

8 mm

Thicker wire means:

Higher strength

Greater load capacity

Higher material cost

Construction and fencing meshes often use thicker wires than light industrial meshes.

2. Wire Spacing

Wire spacing refers to the distance between wires.

There are two directions:

Longitudinal spacing (length direction)

Cross wire spacing (width direction)

Spacing is usually shown in millimeters, such as:

100 × 100 mm

150 × 150 mm

200 × 200 mm

Smaller spacing provides:

Higher strength

Better load distribution

Larger spacing reduces material usage and cost.

3. Panel Size or Roll Size

Welded wire mesh can be supplied as:

Panels

Rolls

Typical panel sizes include:

2 × 3 m

2.4 × 6 m

Roll mesh is defined by:

Width (m)

Roll length (m)

The size depends on handling, transportation, and installation requirements.

4. Welding Type and Strength

Good welded wire mesh has:

Strong weld points

No loose intersections

Flat mesh surface

Industrial welded mesh is produced using automatic mesh welding machines, which ensure:

Uniform welding current

Consistent weld strength

Accurate wire positioning

Welding quality is just as important as wire size.

5. Surface Treatment

Specifications may also include surface finish:

Black wire mesh

Galvanized welded wire mesh

PVC coated mesh

Surface treatment affects corrosion resistance and service life.

Example of a Welded Wire Mesh Specification

Example:
6 mm × 150 × 150 mm × 2.4 × 6 m

This means:

Wire diameter: 6 mm

Wire spacing: 150 mm × 150 mm

Panel size: 2.4 m × 6 m

This type is commonly used for construction reinforcement.

Why Correct Specification Matters in Production

For manufacturers, understanding mesh specifications helps:

Select the correct welding machine

Set accurate wire feeding and spacing

Ensure consistent product quality

Automatic mesh welding machines can be customized to handle different wire diameters and mesh sizes efficiently.

Common Mistakes to Avoid

Confusing wire diameter with wire spacing

Ignoring welding strength

Choosing panel size without considering transport

Overlooking surface treatment requirements

Clear specifications prevent costly errors.

Summary

Reading welded wire mesh sizes and specifications is simple when you understand:

Wire diameter

Wire spacing

Panel or roll size

Welding quality

Surface treatment

Correct interpretation ensures the mesh meets project and production needs.

For stable and large-scale production, professional welded wire mesh welding machines play a key role in achieving consistent specifications.
