In many instances, our standard spill decks and spill deck bladder systems can handle the weight of the drums or containers loaded on top of them. For example, a 55-gal drum of hydraulic oil weighs approximately 425 lb and the 1-drum spill deck is rated for 1500 lb. But for those occasions where extra weight capacity is needed, the Ultra-Spill Deck Plus Models are an excellent option. These units are rated at 10000 lb. per square foot! They still function like other spill decks by connecting via bulkhead fittings and sharing spill containment capacities but have the added features of a slightly lower profile (4.25 in) and the significantly higher weight capacity.
