Wire Mesh FAQs for Products, Costs & Shipping – TWP Inc.

Mesh (or mesh count) is the number of openings per linear inch, measured from the center of one wire to the center of the next.

To determine mesh size, count the number of openings between the center of one wire and the center of a parallel wire one inch away. For coarse mesh, this can usually be done with a ruler. For finer meshes, a mesh counter or optical comparator may be required for accuracy. Mesh count does not account for wire diameter, which also affects opening size and filtration.

It depends on the material and certification. Stainless steel wire mesh, especially Type 304 or 316, is commonly considered food safe and is widely used in food processing applications. However, wire mesh is not NSF compliant unless it is specifically certified by NSF.

Materials such as galvanized steel, carbon steel, copper, brass, or coated meshes are generally not recommended for direct food contact.

Yes. Wire mesh can be used outdoors, but you should choose a corrosion-resistant material. Stainless steel (304 or 316) is the best option for outdoor exposure. Galvanized steel is also suitable, but the protective coating can wear over time. Carbon steel and coated meshes may rust if exposed to weather for extended periods. PTFE-coated mesh is another strong outdoor option because it resists UV, chemicals, and weathering, though the coating can still wear with heavy abrasion.

Both woven and welded wire mesh is produced in 100 foot long (30 M) rolls. Rolls are usually either 36 inches (914mm) wide or 48 inches (1220mm) wide. We sell our mesh as either full rolls or partial rolls. The one exception is our Sintered mesh Thermobond™ that is produced as flat sheets up to 24 inches by 48 inches. Also, our cabinet decorative mesh is sold in panels up to 24 inches by 60 inches.

Yes, they can be supplied for a nominal fee. Please advise us at the time of ordering (by phone or email) if you require material certifications or other documentation. No certifications will be available more than 90 days after shipment.

Yes, many items are available as a special order.

Woven wire mesh is made by interlacing wires over and under each other, similar to weaving fabric. This construction provides flexibility and is commonly used for filtration, screening, and applications requiring precise openings.

Welded wire mesh is made by placing wires in a grid pattern and welding them together at each intersection. This creates a rigid, stable mesh often used for structural, fencing, guarding, and reinforcement applications.
