An ABS locker door replaces a steel pressing in changing rooms where corrosion is a bigger problem than impact, and where the volume does not justify a steel die.
A leisure centre in Manchester replaced 240 steel locker doors that had rusted along the bottom edge. The formed ABS doors cost 40 percent less per unit at that volume and the first batch is still in service after four years.
ABS locker door gauge, ribs and lock detail
- Door to 400 mm: 2.5 mm
- Door 400 to 600 mm: 3 mm
- Ribs: two horizontal, 4 mm depth
- Lock area: bonded reinforcement plate
Ribs are the stiffness trick. Two shallow horizontal ribs 4 mm deep turn a 3 mm panel into something that does not drum when it shuts, at no extra material cost.
Hinges, vents and the finish
Hinges carry the slam load. A hinge bolted through a 3 mm formed panel needs a washer plate on the inside; without it the screw heads pull through within a year and the door hangs crooked.
Vents are formed in, not cut, on a proper tool. Formed vents keep the edge sealed and look intentional; cut slots leave a raw edge that reads as a cheap retrofit and collects lint.

Frequently Asked Questions
What thickness ABS locker door?
2.5 mm for a light changing room door up to 400 mm wide, 3 to 4 mm for larger doors or heavy use. Stiffness at the free edge is the specification.
Why do formed doors crack at the lock?
The lock cut-out removes material at the point where users push. A local rib or a bonded reinforcement plate behind the lock area spreads the load and stops the crack.
Are ABS locker doors cheaper than steel?
At low to medium volume, often yes. A formed ABS door needs a single-sided tool rather than a pressed steel die, and it will not rust in a wet changing room.
