What it is
Purlins run along the length of the roof. Steel purlins are common in terrace sheds and car porches with metal or polycarbonate sheets.
Types and key points
- Run along the roof length
- Carry sheets or battens
- Steel C or Z sections are common
- Spacing set by the sheet type
Why it matters
Terrace sheds are popular in Chennai for shade and drying clothes; purlins and fixings must resist cyclone winds.
How Elamentt handles it
We design terrace sheds with suitable purlins and fixings when you include them.
