Longitudinal Trench Grating

Road Safety Grating's longitudinal bars trench grates are available in both light duty (class B) and heavy duty (class D). Longitudinal bar trench grates feature a 6mm gap between their bars, making them high heel shoe resistant as well as bike and wheel chair safe. Available in both a galvanised and black finish, longitudinal bar trench grates are made from ductile iron, making them a strong and durable product.  Additionally, all longitudinal bar trench grates feature a slide resistant pattern, making them ideal for areas with frequent pedestrian traffic.

What's the difference between longitudinal bars, transverse bars and EGAL trench grating?

Have a look at "Choosing the right trench grate." to see what the advantages of each type are.

What's 'heel guard'?

All longitudinal bar trench grating is made to heel guard standards, with a maximum 6mm spacing between the bars. This narrow spacing prevents high heel shoes from penetrating the grate and hence it is heel guard. In addition to being heel guard, the small spacing also makes the grate meet bicycle tyre penetration resistance (BTPR) standards, also making longitudinal bar trench grating bike and wheel chair safe. Heel guard grates are ideal for areas experiencing frequent pedestrian access, and the use of ductile iron in the longitudinal bar trench grate range presents a highly affordable alternative to stainless and mild steel heel guard grates.

Bicycle Tyre Penetration Resistance

Due to the narrow 6mm gap on the longitudinal bar trench grate range, the range meets bicycle tyre penetration resistance (BTPR) standards as established in AS3996 – 2006. The narrow gap prevents tyres from penetrating the grate, making them appropriate for areas where bikes and wheelchairs may have access.

Slide Resistance

All longitudinal bar trench grating features a slide-resistant boomerang pattern. The pattern facilitates good grip for footwear and tyres and helps prevent slipping.

Strength

The use of ductile iron in the longitudinal bar trench grate range has ensured that the range remains strong and durable. Ductile iron is far stronger than traditional cast iron under both compressive and tensile forces, experiencing less stress under both forces. In addition to being stronger, the use of ductile iron has also lightened the range, reducing material costs and thus making them a more economic product than traditional cast iron trench grates.

Bolt Down

All longitudinal bar trench grates feature two bolt down points (per grate). Trench grates are not supplied bolted down unless specified when ordering. Bolting trench grates down offers numerous advantages, especially in providing security and minimising the risk of theft. Additionally, bolting trench grates down minimises the risk of the grates rocking, eliminating the possibility of unwanted sound as well as increasing the life span of the entire system. Bolts can easily be removed when cleaning is needed.
