Articulated answer to highway gully performance

Highway gully grates

Wrekin Products, manufacturer of intelligent products for civil engineering, has a patented articulated coupling for its new Highway gully grate range. The design delivers the ideal combination of double-triangular non-rock stability with a captive hinge for easy maintenance and long-term security.

Part of the comprehensive Highway range, the gully grates are designed to be simple for specifiers and users to select as well as far exceeding compliance with relevant standards, including BS EN 124 and HA104/09.

“We wanted to give customers the best of both worlds, so we developed a unique, patented articulated coupling that combines the most useful functions of double-triangle and single-unit types. Like all Highway products, we’re streamlining the choice so it’s super-easy to stock, specify, install and maintain. The customer simply chooses the size of gully required and the unique design takes care of everything they need for exceptional performance up to HA104/09 standard.”

Traditionally, gullies tend to be one of two basic designs. A double-triangle format means highway operators benefit from three-point suspension for non-rock stability, but they are not hinged making them less theft resistant and more awkward for gully cleaning.

A common alternative is a one-piece, rectangular hinged gully, which offers better security but is less stable in the long term.

The articulated coupling is flexible enough when closed to allow the double triangles to rest naturally, for three-point suspension. When opened, the captive hinges reduce the risk of theft while providing rigidity to allow easy lifting for gully cleaning.

Due to the unique design, hinging is reversible on most sizes allowing the grating to hinge correctly for the traffic flow direction.

The Wrekin Highway Gully is also available in a vast size range of sizes including twin configuration units.
