Why the coating matters

When buyers compare chain link fence options, the coating on the wire is usually the first decision. Anping County Shengxin Metal Products Co., Ltd describes its Zinc - Aluminum Coating Wire / Galfan Wire Chain Link Fence as wire covered with a Zn-Al alloy, offered in two compositions:

• Al 5%, Zn 95%
• Al 10%, Zn 90%

According to the product description, the corrosion resistance of Galfan wire is about three times that of traditional galvanized wire, which the manufacturer links to a longer service life. The description also says that replacing a traditional zinc coating with a thinner Galfan coating improves weldability and formability. These are the manufacturer's stated performance claims. If your project needs test reports or compliance with a specific standard, ask for that documentation directly. This article does not confirm either.

Step 1: Define your buyer requirements

Before you choose a specification, write down:

1. Site type and purpose: private, public, road and transit, or industrial or agricultural protection.
2. Required fence height and the total run length.
3. What the fence needs to keep in or out, since this drives the mesh opening you need.
4. Exposure conditions at the site, which affect your choice of coating.
5. Framework needs: whether you also need posts and top rails.

Step 2: Choose the wire diameter

The listed wire diameters are 2.8mm, 3.0mm, 3.2mm, 3.5mm and 4.0mm. The product material does not give load, strength or impact ratings for each diameter. Choose a diameter based on your project specification or engineer's requirements, then confirm it with the supplier.

Step 3: Choose the opening (mesh) size

The mesh sizes are 50x50mm, 60x60mm and 75x75mm, and other sizes are available.

Step 4: Choose height and roll length

• Height: 1.2m, 1.5m, 1.8m, 2.0m and 2.4m, with other heights noted as available.
• Length: 9–18m per roll, depending on roll weight.

Because roll length depends on roll weight, the length per roll you receive will vary with the wire diameter and mesh size you select. Confirm the actual length per roll when you calculate how many rolls you need.

Step 5: Match posts and top rails

The specification lists the following framework sizes:

Choose framework sizes that suit your fence height and site conditions. Confirm the compatible fittings with the supplier.

Step 6: Review the surface treatment options

The same specification sheet lists the following chain link fence surface treatments alongside the Galfan description:

• Electric galvanized: the listing says few customers use it directly because the zinc coating is thin.
• Hot-dipped galvanized: the supplier usually recommends either 40–60g/m² or more than 200g/m² zinc coating.
• PVC coated: dark green and black are listed as the popular colors.

If you specifically need the Zn-Al (Galfan) coating, state the alloy ratio (Al 5% or Al 10%) on your inquiry. Confirm which coating, and which coating weight if relevant, applies to your order.

Typical applications

The product material lists these uses:

• Private grounds: courtyards and villa communities
• Public grounds: parks, zoos, train or bus stations and lawns
• Road and transit: highways, railways and city transit
• Facilities: fencing, decoration or protection in industry, agriculture, infrastructure and transport

When this recommendation may not apply

• Your budget or schedule depends on a price or delivery time. The available material gives neither, so you need to request both.

Before you send an inquiry

To get an accurate quotation, send Anping County Shengxin Metal Products Co., Ltd your chosen coating alloy, wire diameter, mesh size, height, total length, and post and top rail sizes, together with your destination market. Confirm specifications, pricing, packaging and lead time directly with the company.
