The present invention disclosed a shipping container comprising a pair of side walls, a rear end, a front end, a roof, a floor and a base frame; said base frame further comprising two longitudinal bottom side rails and numbers of parallel bottom cross members, wherein said floor is made up of corrugated steel floor. These kinds of traversing yarn guiding rods are prone to wear at their bearing points. The arm members each have at least one first attachment feature. In the tank there may be a portion above the liquid filled with a gas with a pressure being lower than the pressure within said environment. The metal precursor is a cyclopentadienyl compound of the metal.
