Chain Link Mesh, Gauge, Coating & Selvage Guide

Start with the opening definition.

State the nominal mesh opening, how it is measured and whether a project standard controls the tolerance. A phrase such as small mesh or standard diamond is not enough for quotation, containment, reach-through or accessory compatibility.

Separate core wire from finished wire.

Gauge conventions vary by market, and polymer-coated wire can be described by the steel core or the finished coated diameter. Record a diameter in millimetres or inches, identify the core where relevant and ask the supplier to return the same measurement basis.

Name the coating system, not only the colour.

Metallic-coated, aluminized, zinc-aluminium and polymer-coated fabrics are different specification routes. For polymer-coated fabric, identify the base wire/coating, polymer type or class when required, colour and any requested evidence. Colour alone does not define corrosion protection.

Control the roll and edge condition.

State finished fabric height, roll length, quantity basis and top/bottom selvage. Knuckled or twisted edges change handling and boundary risk; the appropriate arrangement depends on height, access and project requirements.

Carry fabric identity into receiving.

The quotation, datasheet, roll label, packing list and inspection record should use compatible product identifiers and units. If the delivered description changes the core-wire basis, coating class or edge treatment, hold the comparison open until the difference is resolved.

Project-input schedule.

Carry these fields into the enquiry and return unknowns as open items instead of filling them with generic values.

What a usable supplier response should return.

A useful response does more than repeat the enquiry. It identifies the exact proposed product and component basis, uses the same units and location IDs as the buyer's schedule, and distinguishes confirmed values from assumptions. Where a field depends on a survey, responsible design input, local requirement or another trade, it should remain visibly open rather than being converted into a silent typical value.

The commercial offer should also state what is included, optional and excluded; which drawing or datasheet revision controls the answer; what evidence maps to the offered configuration; and what must be approved before fabrication. This lets buyers compare like with like and prevents a quotation from accidentally closing a structural, safety, civil or compliance decision.
