Product Specification Guide
Type "DT" steel gratings have deep rectangular cross bars and are manufactured by inserting pre-punched bearing bars and cross bars into an “egg-crate” configuration and deforming the cross bars under intense hydraulic pressure. The deep cross bars on type "DT" gratings make them popular for architectural applications such as sun shades and infill panels with the deeper cross bar serving as a distinct architectural accent.
Pressure Locked Gratings manufactured with deep rectangular cross bars are identified as dovetail pressure. These products are assembled by pre-punching both the bearing bars and cross bars, aligning the bars in an egg-crate manner, and deforming the cross bar into the dovetail slot in the bearing bar under intense hydraulic pressure.
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 spacing including a 1/4" or 1/2" opening product. 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 also available in stainless steel. Slip resistant surfaces are available upon request.
