Long extrusion storage on cantilever racking, Neath.
Six metre aluminium extrusions moved from floor stacks into a cantilever run, supported along their length so profiles stop bowing.

The challenge.
- Extrusions were stacked on the floor on bearers, so lower lengths were damaged by the weight above and picking a profile meant unstacking the bundle.
- Long lengths sagged between bearers, producing bowed stock that was rejected at the cutting saw.
The constraints.
- Profiles arrive in mixed bundle sizes and lengths.
- The aisle had to work with the existing sideloader rather than a new truck.
What we specified, and why.
Each line of the specification answers one part of the problem. Here is the reasoning, line by line.
- Single-sided cantilever against the building wall
- Keeps the aisle clear for the sideloader and makes use of wall height that was previously empty.
- Close arm spacing along the run
- Supports long profiles along their length so they stay straight between arms.
- Arm end stops
- Stops bundles rolling off the arm when the sideloader places them.
Installation.
- Installed in sections so goods-in could continue unloading onto the first completed bays.
- Arm levels were set against the bundle heights measured at survey, leaving pitch adjustment for future profiles.
The outcome.
- Each profile is now picked from its own arm level without touching another bundle.
- Saw rejects due to bowed stock stopped once lengths were properly supported.
We stopped losing stock to the bottom of the pile. That alone paid for the racking.
