HDGLS Series serrated top aluminium trench grates are suitable for vehicular traffic in light duty applications, such as residential driveways, parks, recreational harbour or beach foreshores, schools, hospitals, hotels, car showrooms, arenas and stadiums etc. They are specifically designed for car and light commercial traffic and although not considered suitable for public roadway applications, they will accommodate heavier traffic on irregular occasions, such as occasional access for emergency vehicles etc. The HDGLS is designed for somewhat heavier applications than the standard Lathamgrate™ range. This range has slightly closer spaced cross supports at a maximum of 200mm centres and the cross support is of heavier construction, although this is unnoticeable when the grates are in application.
The HDGLS Series consists of a frame that can be supplied with or without an integrated galvanised trench liner, making the frame and liner (if supplied) a permanent part of the floor. The individual grating sections will drop into the frame, making for easy removal for access and cleaning.
The material can be supplied in custom lengths to 4,000mm and factory manufactured fully welded angles and T’s are available for the grates and liners if required.The system is also available with block ends for the frame and trench if required. When the trench liner is used and factory fabricated block ends installed, the system will be an enclosed trough.
Latham can also supply hidden locking mechanisms for the HDGLS Series if required and welded spigots can also be supplied on the trench liner if required.
