1. Define the buyer's constraints first

Write down these points before you compare products:

• Application: perimeter protection and isolation, garden or residential boundary, or light enclosure work.
• Format: rigid fence panels with posts, or flexible mesh in rolls.
• Required fence height: this sets the panel height and the post height.
• Opening size and wire diameter: what the fence must keep out, and how rigid it needs to be.
• Surface treatment: galvanized, PVC coated or powder coated. Choose based on the site environment and the finish you want.
• Colour: only matters if you need coated panels.

2. Product options and their documented specifications

3D Curved Welded Wire Mesh Fence

The listed material is galvanized iron wire or plastic coated iron wire, and the process is welding. Standard fence lengths are 2 m and 2.5 m. The listed applications are protection and isolation for roads, railways, airports, residence districts, seaports, gardens, feeding and husbandry.

The 2405 mm panel length differs from the 2 m and 2.5 m standard fence lengths.

PVC Coated 3D Wire Curved Mesh Fence / Welded Garden Fence Panel

Use this option if you need documented opening and wire figures for a curved panel:

• Material: low carbon steel wire or stainless wire
• Surface treatment: hot dipped galvanized, PVC coated, powder coated
• Mesh size: 50 × 200 mm
• Wire diameter: 4.0 mm, 4.5 mm, 5 mm
• Panel width: 2500 mm
• Panel length: the source lists a range from 1030 to 2430 mm (the first value appears as "1030m" in the source, so confirm the unit)
• Colours: Green RAL 6005, White RAL 9010, Black RAL 9005, Anthracite RAL 7016

3D V Bending Welded Fence Wire Mesh

This bending triangular welded panel is listed with these options:

• Wire diameter: 3.5 mm, 4.0 mm, 4.5 mm, 5.0 mm
• Mesh size: 100×50 mm, 100×55 mm, 120×55 mm, 150×55 mm
• Panel width: 2.0 m, 2.255 m, 2.5 m, 3.0 m
• Panel heights from 800 mm up to 2000 mm, with 2 to 4 bends in the common specification table. A second table for peach type posts runs up to 2530 mm.
• Post height depends on the post type (embedded type or base type). Square or round posts are listed.

Match the panel height, number of bends and post type to the table row by row when you request a quotation.

Welded wire mesh (rolls and sheets)

If your project calls for flexible mesh rather than rigid panels, the welded wire mesh product is listed as bright drawn mild steel wire welded at every intersection. Listed options:

• Wire materials: mild steel wire, stainless steel wire, galvanized steel wire. Stainless steel types 304 and 316 are available in some specifications.
• Processes: electric galvanized before or after welding, hot-dipped galvanized before or after welding, and PVC coated after welding
• Standard roll length 30 m and width 0.5 m to 1.8 m. Special sizes are available on request.
• Packing: waterproof paper in rolls. Custom packing is available on request.

Examples from the published tables:

The source says galvanized weld mesh gives a flatter finish that is easier to use if you are not fixing from both sides. It also says this mesh would generally be used for external projects or areas of moisture.

3. How to compare opening size and wire diameter

• Fence panels (curved or V bending) list wire diameters from 3.5 mm to 5 mm and larger rectangular openings, such as 50×200 mm or 100×50 to 150×55 mm.
• Welded mesh rolls list much thinner wires, mostly around 1.65 to 2.67 mm or BWG gauges, with openings from 6.4 mm up to 100 mm.
• Compare like with like. Do not judge a roll gauge against a panel wire diameter. The source tables give roll wires in both mm and BWG, so state the unit you need on the inquiry.

4. When these recommendations do not apply

• If your project requires certified compliance with a specific standard, ask for documentation. This guide makes no certification claims.

5. Inquiry checklist for wire mesh suppliers

When you contact wire mesh suppliers or wire mesh manufacturers, including for wire mesh wholesale orders, include:

1. Product type (3D curved panel, PVC coated curved panel, 3D V bending panel or welded mesh roll)
2. Panel dimensions or roll width and length
3. Opening size and wire diameter, with the unit (mm or BWG)
4. Surface treatment and RAL colour if coated
5. Post type and post height
6. Quantity, packing requirements and destination

ANPING COUNTY CHENG CHUANG METAL PRODUCTS CO.,LTD. will need to confirm price, lead time and any documentation for your specific order.
