3510 Mesh
358 mesh is certainly one of the most famous anti cut and anti climb welded mesh fence panel system out there, but it's not the only one.
Another option that you might not have heard of is known as 3510 mesh. Like it's big brother, this fence has very small apertures, but it's made from slightly thinner wire.
This means that while it's still hard to cut and climb, it's lighter and a little cheaper than 358 mesh. Unfortunately, 3510 mesh is not as easy to source as 358 mesh, so you might need to shop around if you want to find this product for your fence project.
