The SteelSpan “all-in-one” panel is an innovative modular wall system that does not require a framing system. Its innovative design is ideal for effectively and economically dividing your plant space from floor to roof or for creating ceilings and roofs in commercial and industrial buildings. The non-combustible panels are constructed of a polyurethane insulating core with excellent insulation values.
