Metal lockers corrode. Laminate lockers chip and peel. Timber lockers swell and rot. New Zealand's combination of coastal salt air, significant rainfall, and wide seasonal temperature variation creates storage conditions that expose every one of those material weaknesses faster than most facility managers anticipate. Heavy duty lockers manufactured from heavy duty polyethylene address all of those failure modes simultaneously, delivering storage that genuinely performs across the full service life without the maintenance costs that traditional materials generate.
