Welded Wire Mesh Questions About Sizes, Galvanizing and Orders

It is made with hot-dipped galvanized wire before welding or with black annealed iron wire that is welded first and then coated with zinc. The first process can leave black welding spots on the surface. In the second process, the zinc coating is applied after welding across the mesh surface. The finished material has a flat, uniform surface, firm structure and good integrity.

It is used in poultry houses, egg baskets, runway enclosures, draining racks, fruit drying screens and fences. Match the opening and wire diameter to the physical barrier or support required for the application.

The listed openings range from 1/4 inch by 1/4 inch to 2 inches by 2 inches, with metric equivalents from 6.4 mm by 6.4 mm to 50.8 mm by 50.8 mm. Other rectangular openings are also listed, including 1 inch by 1/2 inch and 2 inches by 1 inch.

Wire diameter depends on the selected opening. The specification table runs from gauge 12 to gauge 27, with each opening associated with its own range. For example, 1/2 inch by 1/2 inch mesh is listed with gauges 16 through 27, while 2 inch by 2 inch mesh is listed with gauges 12 through 20.

Send the required opening, wire gauge or wire diameter, and mesh orientation when asking for a quotation. This gives the supplier the information needed to identify the intended configuration.

With the first process, the wire is hot-dip galvanized before the wires are welded into the mesh. The welding process can leave black welding spots on the surface.

With the second process, black annealed iron wire is welded first and the finished mesh is then coated with zinc. This method is described as providing better corrosion resistance because the finished mesh receives the zinc coating after fabrication.

The choice depends on the surface finish and corrosion-resistance requirements of the project. State the preferred process clearly in the order documents so the quoted material matches the application.

The standard roll length is 30 meters. Listed widths range from 0.5 meters to 2.1 meters. Special sizes are available on request.

For a fence or enclosure project, measure the required coverage and consider how the roll width will be handled at the installation site. For a draining rack or fruit drying screen, check the working dimensions of the frame before selecting the width. Include roll length, width, opening and wire gauge in the request for quotation.

The standard packing is waterproof paper in rolls. Custom packing is available on request.

Tell the supplier the required packing method together with the mesh specification, order quantity and delivery handling requirements. The order should identify the product as a roll and include the requested width and length so the packing matches the shipment plan.

Listed applications include industry, agriculture, building, transportation and mining. Specific uses include poultry houses, egg baskets, runway enclosures, draining racks, fruit drying screens and fences.

A buyer planning a poultry house can compare the required enclosure opening with the listed sizes before ordering. A buyer preparing a fence can check site coverage, roll width and wire gauge together. For either use, send a schedule showing the opening, gauge, roll dimensions, quantity and preferred galvanizing process.
