Stainless steel meshes and grates

Manufacturing and Stock Metal Meshes

Welded protective meshes

Our welded stainless steel protective meshes are made of stainless steel wire. Our smooth-finish wire is available in thicknesses of 2.0–8.0 mm. The wire pitch for long way of design is 25 mm at minimum and 125 mm at maximum. For short way of design the wire pitch is 25 mm at minimum, increasing steplessly above this. The mesh is usually delivered as straight sheets on pallets. This facilitates the transportation of the product and protects the mesh from damage caused during transport. The meshes are used in the likes of the construction industry, foodstuff industry and chemicals industry, where highly corrosion resistant products are required.

The meshes are used for support, protection and reinforcement purposes, as well as in partition walls. They are also used as sub components in the manufacturing of a range of products.

The maximum possible sheet size is 3.0 m (width) x 3.5 m (length).

Woven protective meshes

Our stainless steel and acid resistant woven protective meshes are manufactured from wire. Our standard wire thicknesses are 1.5, 2.0, 3.0, 4.0, 5.0 and 6.0 mm. We can also produce other dimensions to order, however the maximum thickness is 6.0 mm. The strength of the wire is normally in the range of 700–1000 N/mm², however other wire strengths are available on request. The aperture sizes range from 3.0 mm to 100.0 mm, and are measured and stated as solely the open area. We have a whole range of weave types; the most common options are single-sided pressing (SSP), corrugated pressing (CP), and wave pressing (WP).

Protective meshes woven from acid resistant and stainless steel are suitable for a range of different industrial sectors, such as the chemicals, foodstuff, wood processing, mining, shipyard, and vehicle industries.

Expanded metal mesh

Stainless steel expanded metal mesh is manufactured from stainless steel sheets, by a process of cutting and stretching. The apertures of the mesh are diamond shaped. Tammet’s stainless steel expanded metal mesh is durable, easily shaped and stylish. Expanded metal mesh is suitable for a wide range of applications, and our expanded metal mesh is made with a variety of pitches, strand diameters and material thicknesses. When ordering mesh, you will need to consider the direction of the long way of design (LWD) in relation to the size of the mesh. The long way of design can be in either the width of the mesh or the length of the mesh. When placing your order, please state the width of the mesh, i.e. the direction of the long way of design.

Tammet’s stainless steel expanded metal meshes can be made from the following raw material thicknesses: 1.5–2.5 mm.

Conveyor-belt meshes

Tammet’s stainless steel and acid resistant conveyor-belt meshes are produced for either roller driven or gear driven conveyor belts, based on the customer’s plans and wishes. The meshes can be manufactured using a range of wire dimensions, spiral rises and rod spacings, based on the customer’s plans and wishes. The meshes are also produced with different edge options, either welded edges or so-called bent edges. Tammet’s acid resistant and stainless steel conveyor-belt meshes are suitable for locations where the materials must withstand high temperatures, and where conditions are such that a acid resistant or stainless steel material is the only suitable option. These kinds of conditions are found in a variety of industrial sectors, and include packaging machines, ovens, wash lines, and driers. The wire thicknesses available are within the range 1.0–5.0 mm, and the maximum mesh width is 6000 mm. The length may be determined based on the customer’s requirements.

Fine-woven meshes

Tammet’s acid resistant and stainless-steel fine-woven meshes feature small-aperture, thin-wire weaves for a range of filters and enclosures, suitable for the needs of all kinds of industrial sector. Industrial sectors where such meshes are used include the chemicals industry, foodstuff industry, metals industry and building services engineering industry. The meshes are supplied primarily on a made-to-measure basis to suit customers’ needs, but a range of standard measurements are also available. The meshes can be further refined by cutting, folding and perforating. Fine woven meshes are produced with a wire thickness of ø 0.0035–1.0 mm, with a weave aperture of 0.043–10.0 mm.

The materials we use are a stainless steel (EN 1.4301/AISI 304) and an acid resistant steel (EN 1.4401/AISI 316).

Grates and stair steps

Tammet’s acid resistant and stainless steel grates are press welded. We offer a broad and comprehensive range, which guarantees that our grates and stair steps are suitable for all kinds of purposes. Tammet’s grates and stair steps are used in situations where a high level of corrosion resistance is required, such as steel structures, in the likes of offshore construction, the shipyard industry, the chemicals industry, the foodstuff industry, and other areas of construction, such as water processing plants, to give just a few examples. The grates can be supplied either as standard sizes or installation-ready, in accordance with the customer’s plans. When placing an order, please state the grate aperture and the size and type of the load-bearing flat steel (notched or smooth).

The materials we use are a stainless steel (EN 1.4301 V2A) and an acid resistant steel (EN 1.4571 V4A).
