Traditionally designed, Dove Tail slot pressure locked grating offers the high strength and stiffness of welded grating, along with the smooth, clean lines 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 a wide variety of spacings including a _” or _” opening product, which conforms with provisions for the Americans with Disabilities Act (July 1991). These products are part of our Grater Access line and are available with cross bars on 2″ or 4″ 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. This style is available in carbon steel, stainless steel and aluminum. Slip resistant surfaces are available upon request.
