We’re learning a whole new vocabulary as the building rises….
A “column” is a primary, vertical beam.
A “girder” is a support beam.
A “girt” is a horizontal structure in a wall.
A “joist” is a horizontal structure that supports a ceiling, roof, or floor.
And a “purlin” is a horizontal structure in a roof.
Many thanks to Mike Turcotte and his crew at H & S Construction for their patience in answering my structural steel questions. “What’s that beam called, and what’s it for?….” Wikipedia is to thank for concise definitions. Any errors in this post are mine!
