As a supplier of stainless steel wire mesh for many different industries and applications, Steellong produces a wide variety of woven wire meshes. Our production program for square mesh ranges in aperture sizes from 0.025 mm to 14 mm. And in addition to our standard program, which is always readily available from stock, we also run lots of special productions for customer-specific applications.

Requirements in the area of fine filtration are met by using micronic meshes with filter grades ranging from nom. 1 µm upwards.Also for that range of filtermedia, stock productions and customer specific productions are combined.And the plain weave and twilled dutch weaves used in this field, as well as the corresponding support meshes, are also a part of our needs-oriented warehousing program.

Depending on the application, the production width is up to 3 m. For filtration of high viscous media,steellong produces Optimized Plain Dutch Weave filtermedia with filter grades ranging from 10 µm up to 80 µm.In many cases this is supplied from rolls or strips ready for final fabrication by filter manufacturers in final production steps.

This filament-wire connection made of stainless steel offers two advantages, high porosity with absolute homogeneous pore structure and high mechanical stability. Retention rates are ranging from 3 µm up to 100 µm. High mechanical strength coupled with flexibility does allow highly efficient surface and depth filtration with a single filter media.

Stainless steel is an alloy of iron, chromium, nickel, carbon, and other materials. The principal benefit of this product is its resistance to corrosion and/or oxidation. Series 300 stainless steels are chrome-nickel, non-hardening, and austenitic (nonmagnetic). Series 400 steels can be chrome, hardenable martensitic or non-hardenable ferritic (both magnetic). The appearance of stainless steel products with a mill finish may not be suitable for some applications. The appearance can be improved by sand blasting.

Chrome-Nickel, Non-Hardening, Austenitic (Nonmagnetic):

304 Stainless Steel - 304 stainless steel is the most popular type. It contains both chromium and nickel to provide excellent balance between corrosion resistance and workability.

304L Stainless Steel - 304L is low-carbon stainless. The reduction in the amount of carbon makes 304L easier to weld, but reduces hardness.

310/310S - Corrosion resistance better than 304. Excellent oxidation resistance. 310S resists corrosion in welded parts.

316 - Better corrosion, pitting resistance and higher strength at elevated temperatures than 304.

316-L - Extra low carbon variation of 316 to avoid carbide precipitation due to welding.

409 - Combines good elevated temperature corrosion resistance with medium strength and good formability. It can be easily formed using all commonly employed practices.

Note that some stainless steel products are protected by a PVC film. However, because the PVC can peel off, stainless steel finishes are not warranted to be scratch free
