Description and definition of pressure lock gratings
Unlike our pressure-welded range, pressure-locked gratings are simply pressed together under extreme force, resulting in a quicker assembly process. Once completed the performance results are similar to the pressure welded grating, with the exception that all bar centres are based on an 11.11mm increment in both directions. 

Pressure locked gratings are specified and detailed in the same way our pressure welded range are. Therefore please refer to previous section for detailed information.
