Eave Purlin
Overview
Eave Purlins are a vital structural component in Pre-Engineered Buildings (PEBs) and steel roofing systems. Positioned at the intersection of the roof and sidewall, eave purlins provide support, stability, and connection between roof sheets and wall cladding. They not only enhance the structural integrity of the building but also ensure smooth water drainage and proper alignment of roofing sheets.
At BSSM Infra, we design and manufacture precision-engineered Eave Purlins using high-strength galvanized or cold-formed steel sections, ensuring superior durability, accuracy, and load performance. Our purlins are fabricated with exact dimensions to match any roofing system, slope, or cladding configuration.
What is an Eave Purlin?
An Eave Purlin is a horizontal structural member located along the eaves line of a building, connecting the end of roof rafters to the wall columns. It serves as a supporting framework for roof sheets, transfers loads to the main structure, and provides an anchor for gutters, downspouts, and flashing systems.
Eave purlins are typically C, Z, or custom-rolled sections, designed for strength, stability, and precise fitment in PEB and roofing applications.

An Eave Purlin is a structural member placed at the edge (eave) of a building where the roof meets the sidewall. It provides support to roof sheets and helps in proper load distribution to the main frame.
Eave Purlins provide stability to the roof edges, support gutter systems, and connect roof sheets to the sidewall structure, ensuring overall rigidity and strength of the building.
They are typically made from high-strength galvanized steel or cold-formed steel sections, offering durability, corrosion resistance, and long service life.
Unlike regular purlins that are placed along the roof slope, Eave Purlins are installed horizontally at the eaves, providing edge support and a base for gutter and fascia attachment.
Yes, Eave Purlins can be customized in terms of length, thickness, and section type (Z or C) to match specific design and load requirements.
Absolutely. Eave Purlins are an integral part of PEB structures, offering strong connections between roof and wall components.
No major maintenance is needed. Regular inspection for corrosion, fastener tightness, and surface coating ensures long-term performance.
Standard sizes vary depending on the project, but common thickness ranges from 1.6 mm to 3.0 mm and lengths can be made to order as per building dimensions.
Eave Purlins are typically fixed using high-strength bolts or self-drilling screws to rafters or columns. Proper alignment and fastening are essential to ensure the correct transfer of roof and wall loads to the main frame.
Yes, Eave Purlins are often designed to carry the load of gutters and downpipes. They provide a strong edge framework for attaching rainwater drainage systems, enhancing both structural and functional performance.
