A double wall and method of assembly of the double wall for a cargo hopper, such as that of a belly dump trailer, having a unitary inner member and horizontal reinforcing members formed of the same material as the inner member and welded sequentially to the inner member and previously attached reinforcing members. Channel members extend along top and bottom of the inner member and generally "L"-shaped members are sequentially added to reinforce the intermediate area. An "I"-shaped member is added last to permit continuously welded construction.
