Janus International has expanded its line of portable-storage containers. In addition to its MASS (Moveable Additional Storage Structures) units, the company has added four more container styles, each with its own unique features. Some models are foldable and can be erected in 15 minutes, while others are stackable, which offers valuable land conservation. Because the structures are classified as equipment, they may carry tax advantages to the owner as well as eliminate lengthy zoning procedures. A new product brochure can be found at Janusintl.com.
