Product Description

Tec-Sieve Heavy-Duty Expanded Metal Catwalk / Expanded Mesh Catwalk
Tec-Sieve Heavy-Duty Expanded Metal Catwalk / Expanded Mesh Catwalks are economical solutions for industrial walking surfaces.  Design engineers view it as an excellent choice when building maintenance and safety are important design criteria.
Produced by slitting and stretching plate into an open diamond mesh; expanded metal grating permits a strong, durable, light weight walking surface.  It has a high percentage of open area which allows excellent passage of heat and light to surfaces above and below.
The angular position of the strand and the bond makes the expanded metal grating stronger in deflection than steel plate in its original form. The junctions of the strand and bond form a ridged surface for improved traction and slip resistance.
Being made from one continuous piece of metal it yields a greater strength to weight ratio. The surface is naturally slip resistant and for that is used primarily for pedestrian traffic.
Expanded metal grating allows snow, water and oil to drain off easily making a practical yet economical way to assure strength and safety in a walking surface.
Expanded metal grating is available in carbon steel, stainless steel and aluminum. 
Expanded metal has hole patterns of various styles, which are caused by using different mold sets.
