Bespoke Grating

Our client needed one of our H10CA precast concrete headwalls fitted with a GMS sloped grating — but site access presented a challenge.

To overcome this, our team designed and manufactured a bespoke double-hinged opening to the front of the grating, ensuring easy access without compromising performance.
