20ft Blast Freezer Container — Heavy Duty
SKU MG-20REEF-BLASTFRZ · Held at Johannesburg, Gauteng
A 20ft blast freezer container built around an uprated refrigeration pack with a larger condenser, twin fan cowls and additional door frame insulation so it pulls product down quickly and holds -25 C in Highveld summer conditions. Interior is hygienic white with an aluminium T-bar floor rated for pallet traffic, and the machinery has been fully serviced, gas-charged and run-tested at our Midrand depot before release. Meat processors, ice cream distributors and seafood handlers use this configuration as overflow freezing capacity that can be relocated between sites on a tilt-bed truck. Supplied clean and weather-tight with a service report. Requires 380 V three-phase power. Freight is quoted by road distance; collection from the depot is free.

The shell is fabricated from Corten A weathering steel — a copper, chromium and nickel alloy that forms a tightly adherent oxide layer instead of the flaking scale you get on mild steel. That patina slows further corrosion, which is why a 25-year-old box can still be structurally sound while a painted mild-steel shed of the same age has perforated.
Side and end panels are 14-gauge (2.0mm) corrugated sheet welded to a rigid frame of rolled top and bottom rails with cast steel corner fittings on the ISO 1161 pattern. Roof panels are 2.0mm with an arch profile that shifts standing water toward the eaves. Flooring is 28mm marine-grade plywood over steel cross-members on nominal 300mm centres, rated for a 7 260 kg forklift axle load.
Expect surface oxidation on used grades: it is cosmetic. We reject units with through-plate pitting, cracked welds at the corner posts, or bowed rails, because those defects affect stacking strength and cannot be repaired economically in the field.
