Cold Storage Changes the Racking Spec
Direct answer: Cold-store racking is specified differently from ambient racking in three areas: steel with verified low-temperature impact toughness, galvanised or heavy-duty coated finishes for the wet-dry cycling at floor level, and aisle widths set to freezer-rated electric forklifts whose battery range drops at sub-zero temperatures.
Steel grade and coatings
At freezer temperatures steel can lose impact toughness; cold-store projects specify steel grades tested for low-temperature toughness and coating systems that resist condensation-related corrosion at the floor interface.
Uprights near the floor see the worst wet-dry cycling; column guards also protect against corrosion in this zone.
Layout follows the truck
Cold rooms are expensive per square metre, so layouts push density — but electric forklifts are the norm indoors and battery range drops in the cold. Aisle width must match the chosen truck at its coldest performance envelope.
Many cold stores accept narrow-aisle trucks to claw back space; confirm the aisles are designed to the truck, not the other way round.
The small stuff matters more
Lighting, aisle markings and signage corrode and ice over; anti-slip surfaces, heated door areas and frost-protected floor joints affect both safety and racking longevity. Budget them as part of the racking project, not afterthoughts.
FAQ
Does racking need special steel for freezers?
Cold-store projects commonly specify steels with verified low-temperature impact toughness; standard grades may not be suitable below certain temperatures.
Why is corrosion worse in cold stores?
Condensation cycles during door openings wet the steel near the floor, then refreeze — accelerating corrosion at the base zone.
Can we use drive-in racking in a cold store?
Yes, and it is common because cold space is costly, but internal forklift handling requires more care on iced or wet rails.
Do electric forklifts work in freezers?
Yes — electric trucks are standard indoors, though battery capacity and shift length drop in low temperatures; plan charging areas outside the freezer.
