Lathamgrate aluminium trench gratings and frames are an economical, functional and attractive solution to exterior and interior drainage and ventilation problems.
The Lathamgrate serrated texture provides a dynamic and contemporary appearance to compliment today’s architectural designs. Unlike conventional gratings, the Lathamgrate has close centre bars, concealed welds and can be fabricated to form a radius. The Lathamgrate is available for trenches up to 300mm wide.
Lathamgrate aluminium trench gratings and frames offer many benefits over competing products, fabricated from steel or cast iron. Aluminium and brass gratings are lightweight and attractive.
Optional trench liners simplify installation and offer improved performance. Trench gratings are for exterior and interior use, including building entrances and wash-down areas.
The grating bars are 6.25mm wide, which combined with the serrated surface help provide pedestrian safety. The closely spaced bearing bars reduce hazards in high heels. The Lathamgrate is designed for pedestrian traffic.
For heavier applications and for block-ends, angles and radii grates contact Latham Australia before specifying.

The ALGLS Series serrated top aluminium trench grates are designed predominantly for pedestrian applications. They are commonly used in office building entrances, homes, parks, recreational harbour or beach foreshores, schools, hospitals, hotels, showrooms, arenas, stadiums, exhibition and convention centres etc.
The ALGLS 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, whilst the individual grating sections will drop into the frame, ensuring easy removal for access and cleaning. The ALGLS Series Grates and Frames can be supplied in custom lengths to 4000mm and factory manufactured fully welded angles and T’s are available for the grates, frames and trench liners if required.
On request, the system is also available with block ends for the frames and trench liners. 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 ALGLS Series Grate and/or welded spigots on the trench liner if required.

HDGPL 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.
Whilst the HDGPL 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 HDGPL Series are removable solid grate units. They are designed to sit on a formed step or trench base and have an overall depth of 60mm. The grates can be supplied in custom lengths to 4000mm and factory manufactured fully welded angles and T’s are available.
