High-Quality Purlins, Girts & Eave Struts by Sumiraj
In modern steel construction, structural efficiency and long-term durability depend heavily on secondary framing components such as purlins, girts, and eave struts. These elements play a critical role in supporting roof and wall systems, distributing loads, and enhancing the overall stability of Pre-Engineered Buildings (PEBs).
At Sumiraj, we manufacture high-performance purlins, girts, and eave struts using high-grade steel plates conforming to ASTM A607 Grade 50, ensuring superior strength, consistency, and reliability for industrial, commercial, and infrastructure projects across India.
What Are Purlins, Girts, and Eave Struts?
Purlins
Purlins are horizontal structural members installed along the roof slope. They support roof panels, transfer loads to the main frames, and improve resistance against wind uplift and roof deflection. High-quality purlins are essential for large-span steel buildings and industrial sheds.
Girts
Girts are horizontal wall members that support wall cladding and help resist lateral forces such as wind pressure. Properly designed girts enhance wall stability and ensure long-term performance in varied Indian climatic conditions.
Eave Struts
Eave struts are positioned at the junction of roof and wall. They provide support to both roof purlins and wall girts, ensuring a strong transition point and better load distribution at the eaves.
Material Specification & Manufacturing Standards
All purlins, girts, and eave struts manufactured by Sumiraj are produced from ASTM A607 Grade 50 steel, known for its high yield strength and excellent formability.
Key Specifications:
-
Steel Grade: ASTM A607 Grade 50
