What is the standard size of steel matting?
The standard (commercial) size of steel matting comes in two sheets: 4 ft × 8 ft and 6 ft × 20 ft. Mesh openings run from 1×1 to 6×6 inches, and wire gauge from 2.6 mm to 6.0 mm. Custom sizes are made to order.

If you're ordering steel matting for the first time — or you've ordered before but want to make sure you're getting the right spec — this guide covers everything you need to know. We'll walk through standard sheet sizes, mesh opening options, wire gauge ranges, and how each of these choices affects your project.
What Is Steel Matting and How Is It Used?
Steel matting (also called wire mesh or welded wire fabric) is a grid of steel wires welded at regular intervals to form a rigid, flat sheet. It's used extensively in construction for concrete reinforcement, fencing, flooring support, and a wide range of industrial and commercial applications.
In the Philippines, steel matting is one of the most widely used materials in residential and commercial construction. Understanding the different sizes and specifications will help you order exactly what your project needs — and avoid paying for more (or less) than you require.
What Are the Standard Steel Matting Sheet Sizes in the Philippines?
Steel matting in the Philippines comes in two standard sheet dimensions:
| Sheet Size | Dimensions | Common Use |
|---|---|---|
| 4′ × 8′ | Approx. 1.2m × 2.4m | Residential slabs, smaller projects, easy to handle and transport |
| 6′ × 20′ | Approx. 1.8m × 6.1m | Commercial and industrial slabs, road construction, large-scale projects |
The 4′×8′ size is the most common choice for residential projects and smaller contractors — it's easier to transport in a standard truck and can be cut to size on site. The 6′×20′ sheet is preferred for larger pours where you want fewer seams and faster coverage.
If neither of these sizes works for your project, Una Wire Products also manufactures custom-size matting to any dimension you specify.
Steel Matting Size in cm, mm and Feet
| Sheet | Feet | Meters | Centimeters | Millimeters |
|---|---|---|---|---|
| Standard | 4 × 8 ft | 1.22 × 2.44 m | 122 × 244 cm | 1,220 × 2,440 mm |
| Large | 6 × 20 ft | 1.83 × 6.10 m | 183 × 610 cm | 1,830 × 6,100 mm |
Mesh openings: 1×1 in = 2.5×2.5 cm · 2×2 in = 5×5 cm · 4×4 in = 10×10 cm · 6×6 in = 15×15 cm.
What Mesh Opening Sizes Are Available?
The "mesh opening" refers to the spacing between wires in the grid — for example, a 2×2 mesh has wires spaced 2 inches apart in both directions. A smaller mesh opening means more wires per sheet (heavier, stronger), while a larger opening uses fewer wires (lighter, more economical).
| Mesh Opening | Typical Application |
|---|---|
| 1×1 | Fine reinforcement, decorative, security grilles, animal enclosures |
| 1×2 | Chicken wire alternative, garden fencing, lightweight reinforcement |
| 2×2 | Concrete slab reinforcement (most common in residential construction) |
| 4×4 | Road construction, thicker slabs, moderate reinforcement |
| 6×6 | Heavy-duty industrial slabs, perimeter fencing, retaining wall support |
For most residential concrete work in the Philippines, a 2×2 mesh is the standard specification. For commercial flooring and road applications, engineers often specify 4×4 or 6×6 depending on load requirements.
What Wire Gauge Should You Choose?
Wire gauge refers to the diameter of each individual wire in the mesh. Thicker wire means a stronger, heavier sheet — and a higher price per sheet. See the steel matting price list for 2026 for peso prices at each thickness. Una Wire Products manufactures matting in the following wire thicknesses:
| Wire Thickness | Strength Category | Typical Use |
|---|---|---|
| 2.6mm · 2.8mm | Light | Fencing, light-duty reinforcement, decorative applications |
| 3.2mm · 3.5mm | Medium | Residential slabs, general construction reinforcement |
| 4.0mm · 4.5mm | Heavy | Commercial floors, driveways, industrial reinforcement |
| 5.0mm · 5.5mm · 6.0mm | Very Heavy | Road construction, heavy-duty industrial, structural support |
When in doubt about which gauge to specify, consult your structural engineer — they will typically indicate the required wire diameter in the project drawings.
Steel Matting Thickness in mm — Wire Number Conversion
Hardware stores quote steel matting by wire number (#6, #8, #10) while engineers specify millimeters. Here is how the common hardware names map to thickness for our black iron matting:
| Thickness | Hardware Name | Typical Use |
|---|---|---|
| 2.6 mm | — | Light reinforcement, non-structural |
| 3.0 mm | #8 | Light residential slabs |
| 3.5 mm | — | Standard residential floor slabs |
| 4.5 mm | #6 | Commercial floors, driveways |
| 5.5 mm | — | Roads, industrial floors |
| 6.0 mm | ¼ inch | Heavy industrial, road base |
In short: #8 = 3.0 mm, #6 = 4.5 mm and ¼ inch = 6.0 mm. Names vary between suppliers, so always confirm the diameter in mm when you order. Peso price for each thickness: see the steel matting price list.
Steel Matting Sizes and Prices in the Philippines (September 2026)
As a quick reference: the smallest common sheet — 2×2 inch mesh, 4×8 ft, lightest gauge — is about ₱350 per sheet, and the largest standard sheet — 2×2 inch mesh, 6×20 ft, heaviest gauge — runs to about ₱5,450. Every other size sits between those.
For the full per-sheet price at every mesh opening, wire gauge, and sheet size — plus galvanized and stainless — see the complete steel matting price list for the Philippines 2026. It is updated monthly with Una Wire Products' published factory-direct pricing.
What Material Types Are Available?
Steel matting comes in several material types, each suited to a different environment. Sheet size, mesh opening, and wire gauge options are the same across all of them:
- Black iron (plain). Uncoated steel — the standard, lowest-cost choice for matting that will be embedded in concrete slabs, floors, and driveways where it is protected from moisture.
- Galvanized. Zinc-coated for corrosion resistance. Used for outdoor fencing, coastal and wet environments, and any application where the mesh stays exposed. Costs roughly 20–35% more than black iron. See galvanized vs. black iron steel matting.
- Stainless steel. Grade 304 or 316 for maximum corrosion resistance and hygiene — food-processing plants, pharmaceutical facilities, and marine work. The premium option; see stainless steel matting.
- Custom. Any size, mesh, gauge, or material to your specification — how custom steel matting works.
How to Choose the Right Size
When placing an order, you'll need to specify four things:
- Sheet size — 4×8, 6×20, or custom dimensions
- Mesh opening — 1×1, 1×2, 2×2, 4×4, or 6×6
- Wire gauge — 2.6mm through 6.0mm
- Material — Black iron, galvanized, stainless, or chrome-plated
If you have project drawings or specifications from your engineer, those will typically spell out all four of these. If you're working without drawings, a practical starting point for most residential concrete reinforcement is: 4×8 sheet, 2×2 mesh, 3.2mm gauge, black iron.
