Pressure locked grates
Pressure Locked Grates manufactured with deep rectangular cross bars are identified as dovetail pressure locked and are designated by the profile "PD." 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.
