Steel Girder
This framing element is strong enough to support floors, roofs, catwalks and more in a single bound
A steel girder is the primary framing element that supports the concentrated loads of floors or roofs. Common shapes for steel girders are I-beams, C- or channel beams and box beams. Used primarily for bridges and other commerical construction projects, steel girders are strong over long spans despite their relatively small size.
Combining vertical and horizontal steel creates a skeleton frame, making structures like wide arches (and skyscrapers) possible.

Steel girders can be connected with welded plates and rivets, or clamps and heavy bolts.
This steel girder allows the wood beams above to be cantilevered, taking the load off the window wall.

Similar to I-beams are hollow structural section beams (HSS), painted orange here.
