Steel prices move with the market, so any quote you receive is a snapshot, not a fixed number. This guide shows the six levers that build the price so you can read a quotation with confidence.
A crimped mesh quote is driven by material grade, wire diameter and aperture, weave type, coating, quantity and freight. Because steel floats with the market, this guide explains the structure of a quote — including a weight-per-square-metre formula — rather than quoting a price that would be wrong next month.
Each lever moves the price independently; together they explain almost any variance between two quotes.
| # | Factor | How it moves the price |
|---|---|---|
| 1 | Material grade | Spring steel vs carbon steel vs stainless — biggest single material-cost swing |
| 2 | Wire diameter & aperture | Sets steel mass per m² — the dominant cost driver |
| 3 | Weave / crimp type | Lock and flat-top crimps need more forming steps than plain double crimp |
| 4 | Surface coating | Anti-rust oil (standard) vs hot-dip galvanized vs stainless base |
| 5 | Order quantity | Setup and handling spread over more panels lowers unit cost |
| 6 | Freight & packing | Container load, Incoterms and destination port |
The full design envelope we quote against is on the crimped wire mesh specifications page: wire 2.0–14 mm, aperture 3.0–200 mm, panel width up to 2500 mm, with C-type and U-type edge hooks.
The base steel sets both the price and how long the mesh lasts in service.
For vibrating screens and high-impact mining duty, spring steel is the standard specification. After quench and temper it reaches a tensile strength of at least 885 MPa, roughly 40% above a standard carbon grade of similar section. That extra strength resists the cyclic fatigue that breaks lighter wires, so it lowers the real cost per tonne of material screened even though the raw-material price is higher.
Standard carbon grades (such as 45# and similar) are the economical choice for light-duty decorative grilles and protective covers where fatigue is not the limiting factor. Stainless steel (304 / 316) is specified for wet, acidic, saline or food-grade service; it carries the highest base-material cost but removes the need for a separate corrosion coating.
Steel mass drives cost, so estimate it before you ask for a quote. The mass is the wire cross-section multiplied by the mesh structure (how many wires run through a square metre).
| Step | Value (assumed example) |
|---|---|
| Wire diameter d | 3.0 mm |
| Pitch (warp = weft) | 12 mm |
| Cross-section A | (π × 9) / 4 = 7.07 mm² |
| Wires per metre (each way) | 1000 / 12 = 83.3 → 166.7 total |
| Estimated weight | 166.7 × 7.07 × 7.85 × 10-3 ≈ 9.3 kg/m² |
This is a teaching estimate. Real weight varies with crimp shape, edge hooks and tolerance; ask the supplier for the exact mass. The point is that doubling the wire diameter roughly quadruples the cross-section and therefore the mass, which is why wire diameter is the fastest way to change a quote.
Weave, coating, quantity and freight each add a measurable slice on top of the steel mass.
Weave type. Double crimp is the simplest and cheapest to form. Flat-top and lock crimps need additional forming and locking steps, so they carry a small premium that grows with wire diameter and panel size.
Coating. Anti-rust oil is the standard, lowest-cost finish. Hot-dip galvanizing adds a zinc bath and handling step for outdoor service, and stainless base material removes the coating step entirely while raising the material cost.
Quantity. Crimping, cutting, hooking and packing have fixed setup costs. One panel carries them all; a full container of identical panels spreads them, lowering the effective unit price.
Freight. Packing optimisation, container size and the destination port (Incoterms) set the landed cost. Two quotes with identical ex-works prices can land very differently once freight is included.
Spring steel delivers a much higher tensile strength after heat treatment than standard carbon grades, so it survives the cyclic fatigue of a vibrating screen far longer. That longer service life and lower breakage rate is reflected in a higher base material cost. For light-duty decorative or protective mesh, a carbon grade is the economical choice; for mining and aggregate screens, spring steel is the specification that actually lowers total cost per tonne screened.
Heavier wire and smaller apertures both raise the steel mass per square metre, and steel mass is the dominant driver of mesh cost. As a rule of thumb the wire diameter is typically 40-60% of the aperture for a stable screen. A finer aperture also means more intersections to crimp, which adds a little weaving time. Use the weight formula in this guide to estimate mass before you ask for a quote.
Yes, and often more than buyers expect. Crimping, cutting, hooking and packing have fixed setup and handling costs that are spread over the order. A single panel carries the full setup; a full container of identical panels spreads it thin. Consolidating sizes and repeating a proven specification are the simplest ways to lower the effective unit cost.
