WPB Beam — Full Form, Standards, Sizes and Weight Chart

WPB vs HEA vs HEB vs HEM

All four belong to the European wide-flange I-beam family at the same depths but with different flange thicknesses:

• HEA — lightest series (narrower flange) — Indian name: WPB (A)

• HEB — medium series — Indian name: WPB

• HEM — heaviest series — Indian name: WPB (M)

In Indian trade, 'WPB' on its own usually refers to HEB. A structural engineer or supplier will confirm the exact series and grade for any tender.

Applicable Standards

• EN 10025-2:2019 — Hot-rolled products of structural steels — non-alloy structural steels

• DIN 1025-2 / 1025-3 / 1025-4 — Dimensions and tolerances for HEA, HEB and HEM

• Equivalent Indian grade: IS 2062 E350 BR (material) — common substitution

Standard grades supplied are S275 JR and S355 JR, with S355 JR being the most common in Indian PEB and high-rise work.

Where WPB Beams are Used

WPB sections are the default heavy-column section in modern Indian projects — high-rise buildings, transfer beams, refinery and power-plant framing, bridge piers and PEB primary members. The high section modulus per unit weight makes them the preferred choice over equivalent ISMB sections wherever load capacity matters.
