Class D grates and drains are designed for use in public roads, highways, and heavy industrial facilities, these grates are built to handle the extreme loads and high speeds of semi-trailers and heavy trucks. Vincent Buda and Company provides Class D solutions to civil engineers and government contractors who demand absolute reliability and compliance with AS3996.
Our Class D range is manufactured from heavy-duty galvanised steel to ensure it can withstand a 210kN load without failing. These are critical infrastructure components designed to last for decades. We understand that civil projects operate on strict schedules, so Vincent Buda and Company offers same day (Sydney Metro) or next day delivery on our stocked Class D items.

Petrol Station Forecourts: Designed to withstand constant heavy vehicle traffic, including fuel tankers and commercial delivery vans.
Public Road Carriageways: Compliant with council requirements for gully grates and side-entry pits on roads accessed by garbage trucks and emergency services.
