Lathamgrate solid brass 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 brass 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.
