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.

Wire mesh is made from a variety of metals, selected for strength, durability, and resistance to corrosion. The most common materials are stainless steel (especially Grades 304 and 316), galvanized steel, and carbon steel. Depending on the application, wire mesh may also be made from aluminum for its lightweight and corrosion resistance, copper for conductivity, or brass and bronze for decorative or filtration uses. For more demanding environments, specialty metals like nickel alloys or titanium are sometimes... Read more

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.

Wire mesh tolerances vary by material, weave type, and manufacturer, but you can generally expect small deviations in wire diameter, opening size, and overall dimensions. For most standard woven or welded mesh, common tolerances are around ±5% to ±10% for wire diameter and opening size. Woven mesh tends to be tighter and more consistent, while expanded or specialty meshes may have wider tolerances. If you need precise dimensions, ask the supplier for the specific tolerance chart for that mesh... Read more

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.

Yes. TWP offers wire mesh samples for a wide range of needs, from decorative applications to DIY, construction, and industrial use. Our decorative mesh sample kits are ideal for interior designers and homeowners exploring unique styles, while our full selection of wire mesh samples allows customers to evaluate materials for performance, testing, and inspection. Samples are available in many materials, including antique brass and bronze, stainless steel, and more, so you can review textures, finishes, and functionality up close. TWP also offers wire mesh samples for testing and inspection. Most samples cost $10.00 each plus shipping and are charged to your Visa, MasterCard, American Express, or Discover at the time of shipment. Unless otherwise specified, samples ship via USPS Priority Mail. Expedited shipping is available for an additional charge.

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.

Our website provides detailed technical information and photos to help you identify the wire mesh you need. TWP can supply wire mesh based on a specific description or an existing sample, but we are unable to recommend a particular mesh for specialized or engineering-critical applications. If you are unsure which mesh is appropriate, you may: Purchase samples to evaluate suitability Provide a physical sample for identification Consult an engineer or technical specialist in your field for application-specific...

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.
