This type of structure is still in use in many lightweight aircraft using [[welding|weld]]ed [[steel]] tube trusses.
A box truss fuselage structure can also be built out of wood—often covered with plywood. Simple box structures may be rounded by the addition of supported lightweight stringers, allowing the fabric covering to form a more aerodynamic shape, or one more pleasing to the eye.
