Question 1

Why is purlin important in architecture?

Accepted Answer

Purlins are horizontal members that support roof decking between rafters or trusses, letting roofs span longer distances efficiently. They are key to roof load paths.

Question 2

What are the different types of purlin?

Accepted Answer

Types include timber purlins, steel C- and Z-section purlins, trussed purlins and principal-rafter purlins in traditional framing.

Question 3

What materials are commonly used for a purlin, and how do they impact durability and cost?

Accepted Answer

Purlins are made of timber, cold-formed steel or hot-rolled steel. Galvanized steel resists decay and is light; timber is affordable and easy to work but must be protected from moisture.
