Our cold-formed purlins are manufactured from galvanized steel coils conforming to ASTM A653 Grade 50. They are available in thicknesses from 1.5 mm to 3.5 mm and section heights from 102 mm to 352 mm.
Web height, flange, lip, thickness and other specifications can be customized according to the structural and installation requirements of your project.
Z purlins or Z Section purlins are durable and stronger than the C purlins. Z and C purlins are used in combination at overlaps and joints. It acts as a support system and is often placed in between the buildings and the roofing sheets. It ensures that the sheets are tightly attached to the building. Z-purlins are lightweight products and have higher flexibility.
C and Z purlins for roofing and structural applications
Purlins are horizontal structural members used to support roofing sheets, roof decks and other building components. They transfer loads from the roof covering to the principal structural frame.
C and Z purlins are extensively used in steel buildings because they provide structural support while remaining relatively lightweight and straightforward to install.
Ghosh Group manufactures both profiles, allowing customers to select the appropriate section according to the building design, span, loading requirements and connection method.
Final section selection, thickness and spacing must follow the project’s approved structural design.
Galvanized C purlins
C purlins – also known as Cee purlins – have a C-shaped cross-section. They are commonly used to support roofs, walls and other elements in steel and industrial buildings.
Their profile makes them suitable for applications requiring straightforward connections and clearly defined spans. C sections may also be used as wall girts and supporting members, subject to the project’s structural design.
Ghosh Group can manufacture galvanized C purlins in different heights, thicknesses, flange dimensions and lip sizes to suit project requirements.
Galvanized Z purlins
Z purlins have a Z-shaped cross-section that allows adjacent sections to overlap at supports. This makes them suitable for continuous roofing arrangements and longer structural runs.
They are frequently installed between a building’s main structural frame and its roofing sheets. When properly designed and installed, they provide an efficient support system for metal roofing and cladding applications.
Ghosh Group manufactures galvanized Z purlins in multiple section heights and thicknesses, with customization available according to the project specifications.
