Grates
The Griptech™ Advantage
The Griptech™ design features a 5mm bar for heel and wheel safety, combined with anti-slip nodules for a slip resistant surface. Griptech’s patented anti-slip design can be customised to suit a project’s design aesthetic and delivers a P5 slip resistance rating.
The range features a bolt down security system plus the ability to remove for easy maintenance access.
Orca’s Griptech™ products are available in stainless steel and galvanized steel options to meet the design loads and safety requirements of any project.
Pair Orca’s polymer concrete channels with our range of stainless steel, galvanized steel or ductile iron grates and frames. Available in a range of sizes and profile designs, including smooth, dotted or GriptechTM.
The range is designed to meet the performance and design criteria of any project. Use EN1433 to select channels and AS 3996 to specify grates and covers based on traffic type, load and frequency.
Site requirements may determine channel depth if shallow drains are required, and the grating material specified, if corrosive liquids are present or chemical spills may occur. The selection of size and shape of grate intake slots may be influenced by user needs, such as mobility aid accessibility, plus the need for additional safety features such as locking and lifting systems for securing the installation and providing ease of access for maintenance staff.
The design aesthetic of a project may influence the selection of grates and frames based on the visual requirements for architectural elements or landscaped areas. Select from a range of grating profiles and finishes or discuss custom options in the size and shape of intake slots, specific profile designs or alternative colours and finishes.
*Ensure that correct class load of grate is used for the desired application.

Trench Grates
Orca trench grates and frames are a robust solution for trench runs in heavy loading areas, allowing the collection of stormwater runoff with minimal falls in the surrounding slab.
In situations where particularly wide or shallow channels or custom channel solutions require a cast in-situ channel approach, trench grates are the answer. The high open ratio of these grates ensures the free flow of stormwater through the channel, with concrete anchor tabs cast into the surrounding concrete apron for additional bolting and fixing security.
Manufactured to AS3996:2019 with a class load up to Class D and galvanized to AS/NZS4680:2006. Trench grates are ideal for: Factory and commercial forecourts, parking areas, driveway crossovers and retaining walls.
