Yosmite traditionally designed, Aluminum pressure locked grating offers a smooth, clean line of a flush top rectangular cross bar. Bearing bars and cross bars are precision slotted, assembled in egg-crate fashion and hydraulically pressed together to form a tightly locked, rigidly stable panel grid. This grating is available in spacings.

These products are part of our Grater Access line and are available with cross bars on various sizes centers. This is also a popular style in the architectural community because of the aesthetic eye appeal of the product and the ability to maintain tighter tolerances.

Yosmite Gratings available in Stainless steel (SS316, SS321 & SS304) and Aluminium 6063-T6 & 6082-T6 If requested, we can also process other materials

Slip resistant & serrated surfaces also available.

For a press locked grating, the cross bars – which as a rule are made of cold-rolled flat steel – are pressed into the previously punched-out bearing bars. The banding bars are designed as T-shaped or flat sections, and are attached by means of automatic resistance welding. If there is an increased risk of slipping, press locked grating can be manufactured in an anti-skid design. For this, the bearing and/or cross bars are notched on the upper side. With press locked grating, the opposite end meshes are usually of equal size
