What the metal envelope system covers

The metal building envelope is the outer system of an industrial building: the wall and roof surfaces that close the structure, together with the supporting steel structure that carries them. On this site the envelope is presented as a system, not as a single panel product, because the wall, the roof and their junctions have to be planned together before any panel is ordered.

A buyer who approaches the envelope as a system will usually start from the building itself: what the building is used for, how its interior is organised, and which wall and roof areas need to be closed. Those answers shape the inquiry, and the inquiry shapes what can be supplied. This site therefore describes systems and inquiry steps, and it does not publish a specification table.

What the steel structure system covers

The steel structure is the frame that carries an industrial building: the columns, beams and bracing that hold up the roof and walls. On this site the steel structure is presented as a system that works together with the metal envelope, because the frame and the envelope share junctions, loads and construction sequence.

A steel structure inquiry starts from the building plan and the way the building will be used. The frame is then discussed as part of a whole-building system, including design, manufacture and installation as one coordinated service, rather than as a list of separate components.
