THE BUYER'S GUIDE / SELECTION
Buy Expanded Metal for Fencing: How to Choose by Opening Size, Wire Diameter and Application
A guide for buyers who want to buy expanded metal for fencing or for other expanded metal uses. It explains how to tell apart the panel fence systems listed by Anping County Ansheng Wire Meshes Product Co., Ltd., which are specified by wire diameter and hole opening, from expanded metal sheet, which is specified by LWD, SWD, thickness and material. It then compares opening size, wire diameter, panel and post sizes, surface treatment and application, and notes where each option does not apply. Prices, lead times and certifications are not covered because no confirmed material is available for them.
Application and security level: high-security perimeter (airport-type fence), configurable security perimeter (Y-shape fence), basic isolation (double-wire fence), or guards, barriers and walkways (expanded metal sheet)
Opening size: airport-type fence 50x100mm or 60x120mm; Y-shape fence 50x150mm, 50x200mm, 55x150mm, 55x200mm; expanded metal sheet specified by LWD/SWD
Wire diameter or thickness: airport-type panel 5mm cold-drawn low-carbon steel wire; Y-shape fence 3mm-5mm; expanded metal sheet has no wire diameter and is specified by overall thickness
Panel and post dimensions: Y-shape panel heights 2.03m/2.23m/2.43m, lengths 2.0m/2.5m/3.0m, post heights 1.6m-4.0m, SHS/RHS post sizes and 1.5-2.5mm post thickness; airport-type panels 2.04m x 2.88m and 0.495m x 2.88m with 2.9m Y-shaped column
Material and surface treatment: low carbon steel or galvanized wire with galvanized, PVC coated or powder coated finishes for fence systems; carbon steel, galvanized steel, aluminum or stainless steel for expanded metal sheet
Topping and anti-tamper fittings: hot-dip galvanized blade barbed wire or concertina razor mesh, M8X30 anti-theft carriage bolts
Known limitations: expanded metal sheet has sharp edges that need finishing in high-traffic areas and limited load capacity compared with solid metal
Buy Expanded Metal for Fencing: How to Choose by Opening Size, Wire Diameter and Application
If you plan to buy expanded metal for a fence, start by checking what kind of material your project needs. Two listings from Anping County Ansheng Wire Meshes Product Co., Ltd. are relevant here, and they are specified in different ways:
- Expanded Metal Panel Fence: a listing of perimeter fence systems (airport-type fences and Y-shape security fences). Their panels are described as welded mesh made from steel wire, so they are specified by wire diameter and hole opening.
- Expanded Metal (sheet): made by slitting and stretching a single metal sheet into connected strands and openings. It is specified by opening dimensions (LWD/SWD), overall thickness, pattern type and material. It has no wire diameter.
Fencing appears in both listings, but each one is specified and sourced differently. Decide which one matches your drawings before you request a quote.
Step 1: Define your buyer requirements
Write these down before you compare options:
- Application and security level. Is it a general boundary, an industrial guard or a high-security perimeter?
- Required opening size. Think about climb resistance, visibility and what must be kept in or out.
- Fence height and run length. These determine the panel height, panel length and post height.
- Environment. Outdoor exposure and corrosion conditions affect the material and surface treatment.
- Topping and anti-tamper needs. Decide whether you need barbed or razor wire and anti-theft fixings.
Step 2: Compare the fence panel options
The Expanded Metal Panel Fence listing describes two main configurations.
Airport-type fence (high-security sites)
The listing describes this fence for high-security locations such as airports and military bases. Documented components and values:
| Item | Listed specification |
|---|---|
| Mesh wire | 5mm cold-drawn low-carbon steel wire; welded, galvanized and plastic sprayed |
| Large panel | 2.04m x 2.88m, with V-shaped reinforcing rib |
| Small panel | 0.495m x 2.88m |
| Aperture | 50mm x 100mm or 60mm x 120mm |
| Tensile strength | 400MPa |
| Welded point tensile force | 1320N |
| Y-shaped column | 60x60x2mm rectangular steel pipe, 2.9m high, Q235, internal and external anti-corrosion treatment, Q235 cap |
| Blade barbed wire | Hot-dip galvanized, 500mm outer diameter, BWG12#-14# wire, BTO-22 blade, cross or spiral installation; 33 coils per roll, 5.1m standard coverage, 10kg per roll |
| Connecting plate | 66x30x4mm Q235, galvanized and plastic sprayed |
| Anti-theft bolt | M8X30 carriage bolt, Q235, hot-dip galvanized |
Y-shape security fence (configurable)
The listing describes this fence as reinforced with V-shaped support arms, welded mesh panels or chain link fencing, safety fittings and hot-dip galvanized concertina razor mesh. The listed ranges are:
| Parameter | Listed options |
|---|---|
| Panel height | 2.03m, 2.23m, 2.43m, etc. |
| Panel length | 2.0m, 2.5m, 3.0m, etc. |
| Wire diameter | 3mm-5mm |
| Hole opening | 50x150mm, 50x200mm, 55x150mm, 55x200mm |
| Number of curves | 2, 3, 4 |
| V-mesh panel | 0.5x2m, 0.5x2.5m, 0.5x3m, etc. |
| Post height | 1.6m to 4.0m (1.6, 2.0, 2.2, 2.5, 2.8, 3.0, 4.0m) |
| Post size | SHS 50x50mm, 60x60mm; RHS 40x60mm, 60x80mm |
| Post thickness | 1.5mm, 2.0mm, 2.5mm |
| Material | Low carbon steel wire, galvanized wire; steel pipe |
| Surface treatment | Galvanized, PVC coated, powder coated |
How to read these options
- Opening size. The airport-type fence lists smaller apertures (50x100mm and 60x120mm) than the Y-shape range (50x150mm to 55x200mm). If a smaller opening matters for your site, compare these values directly.
- Wire diameter. The airport-type panel is fixed at 5mm. The Y-shape fence lists 3mm-5mm, so you need to state the diameter you require.
- Height. Match the panel height and post height to your total fence height, including any topping.
The same listing also mentions double-wire fences for residential communities, industrial parks and farms, and chain link fences. Use those for basic isolation needs rather than high-security perimeters.
Step 3: Decide whether you need expanded metal sheet instead
Some buyers searching for an expanded metal security fence or expanded metal fence panels actually need cut-and-stretched sheet. The Expanded Metal listing includes fencing, machine guards and safety barriers among its common uses. Its documented selection points are:
- Pattern type: standard (raised), which has a textured, slip-resistant surface; flattened, which has a smooth finish for architectural uses; or micro-expanded, a fine mesh for filtration or screens.
- Material: carbon steel (affordable and strong), galvanized steel (rust-resistant for outdoor use), aluminum (light weight, corrosion-resistant) or stainless steel (for harsh environments).
- Opening and thickness: for stair treads and ladder rungs, the listing gives LWD 1.0-4.0 inches, SWD 0.25-1.50 inches and overall thickness 0.100-0.450 inches. Panel sizes are customized. These ranges are stated for treads and rungs, not for fencing, so confirm fence-specific values separately.
- Surface treatment: galvanized, powder coated, painting, etc.
Limitations from the listing: expanded metal has sharp edges, which need finishing in high-traffic areas. Its load capacity is also limited compared with solid metal.
Quick selection summary
| If your requirement is… | Consider |
|---|---|
| High-security perimeter with smaller apertures and razor topping | Airport-type fence (5mm wire, 50x100 or 60x120mm aperture) |
| Perimeter security with configurable height, opening and post size | Y-shape security fence (3-5mm wire, 50x150 to 55x200mm openings) |
| Basic boundary for residential, industrial-park or farm use | Double-wire fence (per listing) |
| Guards, barriers, screens or walkways made from one stretched sheet | Expanded metal sheet (specify pattern, material, LWD/SWD, thickness) |
When these recommendations do not apply
- If your specification requires a cut-and-stretched expanded metal mesh fence, the panel fence systems above are welded wire and will not meet it. Ask for expanded metal sheet with fence-specific dimensions instead.
- If you need openings, wire diameters or post sizes outside the listed values, confirm availability before ordering.
- This guide does not cover prices, lead times, certifications or compliance with any national standard. No confirmed material is available for these points, so request written confirmation for your market and project.

Send your application, fence height and length, required opening, wire diameter or sheet thickness, material, surface treatment and topping requirements to Anping County Ansheng Wire Meshes Product Co., Ltd. Ask for a written specification that confirms every value before you place an order.
