Woven stainless steel mesh is used for a large number of applications, including filtration, ventilation, machine guards, pest proofing. Our woven 12 Mesh is more mesh-like than cloth-like, however it is a flexible mesh so may need the support of a frame to add rigidity.
The mesh count refers to how many holes there are on a linear inch on the material i.e. if you place a ruler on the mesh, our 12 Mesh would have 12 holes per linear inch.
We can offer either standard grade 304 stainless steel with a 1.56mm hole, or the higher quality grade 316 and grade 316L stainless steel with a 1.62mm hole (sometimes called Marine Grade). Grade 316 and grade 316L stainless steel contains molybdenum, which is added to boost its resistance to corrosion and should be selected if the material is to be used in a salt water or coastal environment. Grade 316L has a slightly lower carbon content, which is preferred for welding.
Please note that from time to time we may substitute grade 304 stainless steel for the higher quality grade 316 stainless steel (unless we are requested not to do so). Samples are supplied from off-cuts of the woven mesh, and so may alternate between Grade 304 and Grade 316 stainless steel.
The material is priced per linear metre on the website.

Hi, you kindly sent us some Stainless Mesh samples. The client is asking us what life span would be expected for a Marine Environment.
Please see below a link from the British Stainless Steel Association website which provides some information on lifespan:
As you can see, the estimate for corrosion to penetrate 1mm in a marine environment with grade 304 stainless steel would be approx. 145 years (as opposed to 260 years for grade 316). Although this seems like a long time, some pitting and staining of the grade 304 material may occur relatively quickly in a marine environment, which obviously has an impact from an aesthetic point of view.
Generally speaking, grade 316 stainless is the preferred option in marine environments. However, any stainless steel option will be preferable to a galvanized finish mild steel option.
