Type “DT” Dovetail Pressure Locked Steel Grating

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 sunshades and infill panels with the deeper cross bar servicing as a distinct architectural accent.
