The new Port of Mackay Container Depot is a major infrastructure project designed to support containerised freight imports and exports for Central Queensland.

With a 1.3-hectare heavy-duty concrete laydown area adjacent to George Bell Drive, the depot has been designed for demanding port operations, including regular container handling, reach stacker movements and heavy vehicle traffic.

Mascot Engineering was proud to supply heavy-duty access and drainage products for this important port infrastructure project.

Products Supplied

Mascot Engineering Gastight Access Covers and Linear Trench Grate & Frame

• 450mm clear opening ductile iron trench grate and frame systems in 900kn load ratings (EN124 F900)
• Gas – and watertight concrete infill access covers in 900kn load ratings (EN124 F900)

The Australian standards for load ratings is known as AS3996.  This is their version of EN124.  Class G products are rated to 900kN under AS3996:2019 and are comparable to EN F900 loading, making them suitable for heavy-duty infrastructure environments where extreme wheel loads and operational demands are expected.

The gas- and watertight concrete infill covers provide secure, authorised service access while allowing the cover surface to be finished in line with the surrounding concrete hardstand.

Built for Heavy Infrastructure

Ports, airports, intermodal terminals, and industrial hardstands rely on strong, reliable drainage and access infrastructure.

The Port of Mackay Container Depot required products capable of handling heavy traffic while supporting efficient surface water capture, secure access to underground services and long-term performance across a large hardstand and laydown area.

Mascot’s ductile iron trench grate and frame systems, together with gas- and watertight infill access covers, are designed for these types of applications, combining strength, durability, serviceability and hydraulic performance.

F900 Capability

Mascot Engineering has extensive experience manufacturing and supplying products for demanding civil and infrastructure projects to 900kN loadings throughout Asia Pacific.

For port and airport environments, EN124 F900 trench grating and access covers provide the load performance required for heavy vehicles, container handling equipment, hardstand areas, tarmacs and other high-load zones.

Mascot also has the capability to manufacture larger span trench grating, including 600mm, 750mm, 900mm, 1000mm, 1200mm and 1500mm clear openings, as well as multipart access covers in Class G loading to AS3996 and EN F900. This supports projects where heavy-duty performance is critical.

Designed for Tropical Rainfall Events

In tropical and coastal environments such as Mackay, drainage infrastructure must be able to perform during intense rainfall events.

Like other tropical regions, including parts of Southeast Asia such as Singapore, Mackay can experience heavy rainfall where large volumes of water need to be captured and moved quickly across hardstand and paved areas.

For airports, defence projects, container depots, ports and logistics facilities, effective surface water capture is critical. Large concrete hardstands can generate significant runoff during heavy rain, making grate opening, trench capacity, frame strength and hydraulic efficiency important parts of the overall drainage solution.

Mascot’s trench grating is designed to support fast water capture while maintaining the strength required for heavy-duty infrastructure.

Secure, Stable and Easy to Install

The ductile iron grates and access covers supplied for the project are bolt-down for security and stability.

Mascot trench grates include machined bearing surfaces to help prevent rocking. When combined with the bolt-down facility, this provides an anti-rock feature that improves long-term performance in high-traffic areas.

Mascot’s trench grate frames are designed for practical installation and can be installed using either a single-pour or two-part pour method.

The gas- and watertight infill covers provide secure service access while helping protect underground assets from water ingress and odour or gas transfer where required, making them ideal for use in trench runs for fuel lines.

Designed for Fast Water Capture and Reliable Access

Large hardstand and laydown areas need drainage products that can capture surface water quickly and efficiently, while also providing safe and reliable access to underground infrastructure.

Mascot ductile iron trench grating is well suited to these environments, providing the strength needed for heavy infrastructure while maintaining hydraulic efficiency across large paved areas.

Mascot concrete infill access covers complement the hardstand finish, creating a strong and consistent surface while maintaining access for inspection and maintenance.

This makes the combined product solution ideal for ports, airports, hardstands, tarmacs, container depots and other locations where high load capacity, fast water capture and secure service access are all critical.
