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.
