NPB Beams
NPB beams (Narrow Parallel Flange Beams, also called IPE beams) are parallel-flange I-sections used in structural framing. Enquire with SIIPL for sections from 100 mm to 600 mm, with dispatch from our Kalamboli stockyard and sales coordination through our Chembur head office. Confirm the exact mill designation and section properties against your design.

FAQ
What is the difference between NPB and IPE?
They are the same section. NPB (Narrow Parallel Beam) is the Indian trade name; IPE is the European designation under EN 10025. Both refer to narrow-flange parallel I-beams.
Can NPB replace ISMB in a structural design?
Often yes, with a structural engineer's check. NPB parallel flanges simplify bolted connections and may reduce weight versus the equivalent ISMB at the same load.
How do I get a price for NPB Beams?
Send the exact size, grade, approved make, quantity and delivery location. Request a dated quotation with validity, taxes, freight and processing charges clearly stated; chart weights are not a price or stock commitment.
Are all listed NPB Beams sizes available immediately?
The size chart is a reference, not a live inventory feed. Confirm the requested size, grade, make, available lengths, minimum order quantity and dispatch schedule with SIIPL before placing an order.
What should I confirm about mill certificates and billed weight?
Include your mill test certificate, material marking and heat-number traceability requirements in the enquiry. Agree whether billing uses actual weighed weight or another stated basis, and request the relevant weight records before order confirmation.
Can I enquire about exporting NPB Beams from India?
Yes. Share the destination country and port, exact product standard and grade, quantity, delivery schedule, packing and inspection requirements. SIIPL reviews export requirements individually; destination compliance and commercial terms must be agreed for the order.
