Made of steel sheet. Epoxy resin-coated. The cabinets are made of steel sheet 10/10. The screws guarantee the same sturdiness and rigidity of the one-piece cabinets. The cabinets can be supplied with or without doors and feature a lock with 3 locking positions and two keys; the height- adjustable galvanized steel ledges, 25 mm away from the other, can be placed according to the needs. The ledges for the 520mm deep cabinets are obtained by placing two 260 mm ledges one next to the other, thus improving their load-bearing capacity. The cabinet is supplied with 4 standard ledges and delivered disassembled, to optimize the storage volume, thus reducing the risks and freights.The 275mm deep cabinets must be anchored to the wall using the brackets included in the supply.
