Poroplate® diffusion-bonded wire cloth laminates are made from layers of stainless steel wire cloth, which are furnace-sintered together into seamless sheets. These porous metal structures provide the accurate filtration characteristics of wire mesh for greater strength and durability.

Poroplate® screens can be fastened by several methods, including welding, caulking bars, and threaded fasteners which are welded to the downstream mesh layers. The screens are manufactured to precise dimensions that assure a perfect fit, which Purolator guarantees.
