Steel Frame Construction

Steel Frame Construction is extremely variable, so we do not have a full typical detail library, instead we have a few details to give you some idea of what steel details might look like.

Notes on Steel With Panels

1.) Drill point panel screws can drill through steel up to 3/8″ thick, but it is much preferable to have wood blocking to which the panels attach. Wood blocking should be a minimum of 3″ deep, to accommodate the required minimum 2″ of screw embeddment.
2.) Steel should not be embedded in panels, steel embedded in panels is a huge thermal bridge. Even worse than the effect on energy performance, is the fact that it is a point where water will condense and rot the panels. We would very much prefer not to embed steel in panels, because it greatly reduces the long term durability of the structure.
3.) Panels infilling between steel members is difficult to build, and eliminates most of the thermal and air sealing performance benefits of using SIPs.
4.) Paying attention to details like the deflection of the steel under load and the effect of temperature changes on the metal is important. If the building flexes considerably the normal air sealing details of the SIPs will not endure the motion. Typically this is dealt with by large expansion joints filled with spray foam, or stiffer steel specifications.
