Beams are long, straight structural members engineered to carry loads primarily through bending resistance. Rolled or fabricated in profiles such as I-sections (universal beams), H-sections (universal columns), T-sections and box beams, they combine high moment of inertia with efficient material use to span large distances with minimal deflection. Commonly made from mild steel (for general framing) or high-strength alloys (for heavy-duty and long-span structures), beams form the “skeleton” of almost every modern building, bridge or industrial installation.

Building frames: Primary support for floors, roofs and mezzanines in commercial residential construction
Bridge girders: Main load-carrying elements in highway and railway bridges, including box and plate girders
Cranes & gantries: Rails and runway beams supporting overhead traveling cranes in warehouses and shipyards
Heavy equipment bases: Structural backbone for mining shovels, dumpers and large industrial presses

Types of Beams

UBs (Universal Beams) / I-Beams

UBs are hot-rolled “I”-section beams with relatively narrow flanges. Optimized for bending about their strong axis, they offer an excellent strength-to-weight ratio for general structural framing.

UCs (Universal Columns) / H-Beams

UCs are wide-flange “H”-section beams with flanges nearly as wide as their depth. Their large moment of inertia and shear area make them ideal for heavy-load columns and long-span beams.

ISMBs (Indian Standard Medium Weight Beams)

ISMBs are India’s BIS-specified series of medium-duty I-beams, rolled to IS 808 dimensions. They match global UBs in profile but have flange-and-web thicknesses tailored to Indian design loads.

NPBs (Narrow-flange Plate Beams)

NPBs are built-up girders fabricated by welding slender flanges to a plate web. They allow custom depths and section moduli when rolled sections aren’t available in the required size.

WPBs (Wide-flange Plate Beams)

WPBs are plate girders with wide, plate-fabricated flanges. Functionally similar to rolled H-beams but fully customizable, they deliver very high load capacity for bridges, cranes, and heavy industrial structures.
