Steel Beams — ISMB, NPB & Wide Flange
Steel beams are hot-rolled I- and H-section members for floors, frames, pipe racks and equipment supports. Teshi Group stocks and supplies ISMB beams to IS 808, NPB parallel-flange beams and wide flange (W) beams in IS 2062 and ASTM grades. Quotes are sent in 24–48 hours.
Also called: ISMB beam, I-beam, joist, NPB beam, wide flange beam, H-beam, girder
What is a Steel Beam?
A steel beam carries load mainly in bending, with two flanges taking compression and tension and a web resisting shear. ISMB (Indian Standard Medium Beam) sections have tapered flanges and are rolled to IS 808. NPB and wide parallel flange (WPB) beams have parallel flanges, which simplify bolted connections, and follow IS 12778 or European section tables. Wide flange (W) shapes follow ASTM A6 dimensions, typically in ASTM A992 or A36 steel. Beams are chosen for building frames, pipe racks, crane girders, platforms and equipment skids.

Steel Beam: common questions
What is the difference between ISMB and NPB beams?
ISMB beams to IS 808 have tapered flanges. NPB (narrow parallel flange) beams have flanges of uniform thickness, which makes bolting easier and often gives a better strength-to-weight ratio.
Which steel grade is used for structural beams in India?
IS 2062 E250 (formerly Fe 410) is the most common; E350 is used where higher strength is needed. Sub-grades A, BR, B0 and C differ in impact test requirement.
Where can I find ISMB weights?
Our IS 808 ISMB chart lists sectional dimensions and weight per metre for each size. Weights are nominal and are useful for estimating tonnage and transport before ordering.
Does Teshi manufacture steel beams?
No. Teshi Group is a stockist and supplier of Steel Beam, sourced from established mills and supplied with the original mill test certificate. Teshi is an OEM manufacturer of flanges, fittings, fasteners, valves and custom fabrications, which can be ordered with it.
