Allproof Industries' commercial linear drainage provides a solution for all heavy-duty channel requirements. Available in a range of sizes and grate options, and available rated from load class A to E.

Design requirements

• All channels and grates come as standard with lockdowns to secure the grates and prevent any damage through movement. Security lockdowns may be available depending on system set-up and project requirements. Please contact Allproof for more information.
• Grates from this range can be utilised on other systems manufactured by Allproof Industries, allowing designers to create consistency throughout their projects.
• The system design accommodates runs of up to 43 meters, terminating at a sump. A mirror image can then be run in the opposite direction, resulting in a maximum length of 86 meters between sumps. Overall, the system length is unlimited. This may be reduced dependent on required capacities or other constraints. Allproof recommends engaging a Hydraulics Consultant with your exact requirements.
• On site mitre cuts are used to form corners, junctions and irregular lengths.
• Joints can be sealed with a suitable flexible sealant if required.
• Outlets are achieved by utilising pre-marked knockouts.
• Allproof supplies a wide range of grates to meet durability and capacity requirements. These include stainless steel, galvanised steel, glass-filled nylon and cast iron.
