RS Joist Manufacturer & Supplier in India

Sarthak Ispat Private Limited is a reliable RS Joist (Rolled Steel Joist) manufacturer, supplier, and exporter in India, supplying high-strength structural joists for industrial buildings, infrastructure projects, heavy fabrication, and global EPC contracts.

Our RS Joists, including widely used profiles such as ISHB (Indian Standard Heavy Beam) and WPB (Wide Plate Beam), are hot-rolled structural steel sections designed to deliver excellent load-bearing capacity, structural rigidity, and fabrication efficiency. Manufactured in compliance with IS 2062 and IS 808 standards, Sarthak Ispat’s RS Joists are trusted for both domestic construction and international export applications.

What is an RS Joist?

An RS Joist (Rolled Steel Joist) is a hot-rolled structural steel section used primarily as a load-bearing member in buildings and industrial structures. RS Joists typically feature a beam-like cross-section that provides high resistance to bending and shear forces.

In the Indian and international steel market, RS Joists are commonly designated as ISHB (Indian Standard Heavy Beam) or WPB (Wide Plate Beam), depending on flange width and sectional proportions. These sections are preferred where higher strength and stiffness are required compared to standard medium beams.

Sarthak Ispat manufactures RS Joists with strict dimensional accuracy to ensure predictable structural behavior, ease of fabrication, and reliable performance under heavy loads.

RS Joist Size Range & Classification

Sarthak Ispat supplies a wide range of RS Joist profiles to meet medium, heavy, and extra-heavy structural requirements.

Exact designations, sectional properties, weights per meter, and thickness details are provided with Mill Test Certificates for engineering review and approval.
