The GDP range of Modular Grated Drainage Channel Systems featuring a Galvanized grate which is available in Transverse, Longitudinal and Perforated options, depending on the application.

The standard transverse grate comes Hot Dipped Galvanized (HDG) and enables a high liquid inflow and are certified to AS3996 for Class D traffic loading after the channel is concrete encased, whilst meeting the requirements for bicycle traffic.

The channels provided feature a galvanized edge rail, as well as a male to female interlocking connection, which secures components both during and after the installation process.  A knockout point is available in the female end of the channel, to assist in fitting a pipe. 

Longitudinal Galvanized Trench Grates are independently tested and certified in a NATA lab to ensure conformance to AS4586 (Slip Check) which ensures suitably when an anti-slip pedestrian safe product is required.  This is a cost-effective alternative option to where Stainless Steel grating has been traditionally used in an anti-slip environment for its anti-slip feature and not material characteristics.  This option is a standard stocked product, in comparison to anti-slip stainless steel grating which is made to order.

A lockdown system is provided to ensure the grate is secured at all times.  These are commonly used in applications to minimise movement/noise of the grate in the channel and reduce the risk of theft.

Drainage channels are available in 130mm, 160mm, 200mm and 270mm openings with interchangeable grates.
