Each bottom side rail is built of a 155x52x30x28x4.5 mm thick cold formed double "Z" section steel made in one piece.
The lower flange of the bottom side rail is outward so as to facilitate easy removal of the cross members during repair and of less susceptible corrosion. Reinforcement plates to be made of 4.0 mm thick flat steel is welded to bottom corner fitting. The cross members are made of pressed channel section steel with a dimension of 45x122x45x3.5 mm for the normal areas and 75x122x45x4.0 mm for the floor butt joints. The large one is reinforced by three 4.0 mm thick gussets.
