1. Start with your site's requirements

Before comparing specifications, write down:

• The threat you are guarding against. Is it casual trespass, climbing, or attempts to cut through the fence?
• The site type. Examples include a prison, airport, border, factory, warehouse or a general commercial perimeter.
• The environment. Outdoor, all-weather exposure affects which surface finish you choose.
• Access points. List the driveway and pedestrian openings that will need gates.
• Inspection needs. Decide whether your project needs third-party inspection before shipment.

These answers tell you whether this product fits your site and which wire and finish to specify.

2. Opening size: the defining feature

The supplier's standard mesh opening is 76.2×12.7mm. Hole size is checked for uniformity during welding inspection.

According to the supplier, the narrow openings stop hands and feet from getting into the mesh. This makes the panels hard to grip and climb, even with tools. That is why the product is described for high-security areas such as prisons, military bases and high-security industrial facilities.

Selection tip: If anti-climb performance is a core requirement, this opening is the main reason to choose the product. If your site only needs boundary marking, a wider mesh product may be enough (see section 6).

3. Wire diameter: 3mm, 4mm or 5mm

The panels are mainly made from low-carbon steel wire, such as Q195 or Q235. The supplier notes that this steel balances strength and formability. Documented wire diameters are:

The supplier links resistance to cutting with a large wire diameter and a dense wire layout. It says traditional tools such as bolt cutters struggle to get through the thick wires and tight mesh. If cutting resistance is a priority, ask for 5mm wire in your quotation request. Then confirm with the supplier which diameter suits your risk level.

4. Surface finish

The published information lists PVC coating and hot-dip galvanized surfaces. Finished panels are checked for peeling, rust, pinholes and uneven coating. They are also tested for anti-corrosion performance for outdoor security projects such as prisons, airports, borders and factories.

The material doesn't give coating thickness values or service-life figures. Ask for these in writing if your specification needs them.

5. Matching gates for a complete perimeter

For full perimeter projects, the supplier offers security gates designed to match its anti-climb mesh:

• Single leaf gates, double leaf swing gates and automatic sliding gates, for vehicle and pedestrian access
• Gate frames in the same steel and anti-corrosion finish as the panels
• Optional frame tube sizes and wall thicknesses that match the fence specification
• Gate height and width made to fit your driveway opening
• Lock sets, hinges and mounting fittings supplied with the gates
• Heavy-duty versions for high-security sites such as factory entrances, warehouse gates and prison access

The published gate finish is hot-dip galvanized plus PVC coated, for outdoor all-weather use.

6. When this product may not be the right choice

The 358 design suits sites where anti-climb and anti-cut performance matter. For general security and perimeter protection, the same company also offers a Double Wire Fence (also called Twin Wire Mesh Fence). It uses vertical wires combined with double horizontal wires.

The Double Wire Fence comes in standard colors: green (RAL6005), black (RAL9005) and white (RAL9010), with custom colors also available. It may suit schools, sports fields, residential areas and other public sites that don't need a very fine opening. If your project's main risk is people climbing or cutting through, the features of the 358 design are aimed at that problem.

7. Quality checks before shipment

The supplier describes a four-stage inspection process for every batch:

1. Raw material inspection. Wire diameter, zinc coating thickness and hardness are checked on incoming steel. Steel that fails is returned.
2. Welding and semi-finished inspection. Checks cover spot-weld strength, hole-size uniformity and panel flatness. Deformed or poorly welded panels are reworked.
3. Finished surface test. The PVC or hot-dip galvanized surface is checked, and anti-corrosion performance is tested.
4. Final random inspection before loading. Samples are checked for panel dimensions, matching post sizes, packing quantity and packaging condition.

The supplier accepts third-party inspection, such as SGS or BV, at the client's request. It states that inspection reports are available for checking bulk orders.

8. What to confirm with the supplier

The published product information doesn't include panel heights, panel widths, post types, installation methods, prices, lead times or product certifications. Include these in your inquiry:

• Panel height and width, and post size and spacing
• Wire diameter (3, 4 or 5mm) and surface finish
• Gate types, sizes and number of gates
• Whether you need third-party inspection
• Your target market's project or code requirements, so the supplier can confirm whether they can be met
