We deal in a wide range of Narrow Parallel Flange Beams (NPB) as per Indian standards. NPBs are constructed to withstand and carry more transverse loads while using 15-20% less material than other beams. They are available in various sizes and grades of mild steel from 16 metric tons in quantity and can be used for construction work and increasing infrastructure strength and lifespan.

1. NPB
We deal in a wide range of best quality NPB (Narrow Parallel
Flange Beams), which are also used as beams where inside flange
surfaces are parallel. As per standard, flange of the Beam are
lower than its depth. NPBs are so constructed that they can
withstand and carry more transverse load. The advantage of NPBs
is, that they help in saving 15-20% of the materials used. We deal
in NPB, prepared as per the industrial standards and are available
in various sizes and are offered at discounted prices.
