Usually aluminium panels used to support palletized cargo in order to reduce damage. Holds of refrigerated ships carrying cargo in pallets and in bulk are fitted with sideshorings. While loading bulk cargo, the sideshorings do not have to be removed from the side of the cargo hold. While set vertically, they secure the palletized cargo during transport resulting in less damage. An innovative type of sideshoring, consisting of multichambered rubber bellows, has been developed and patented by the Swedish company KALLNER REEFER.
