Straight answers on sizes, thickness, weight, grades, MTC, pricing and ordering — so your enquiry is specification-ready before you send it.
01
What is an NPB beam?
NPB Beams refers to narrow parallel flange beams identified by an exact NPB designation. It is used in space-conscious structural frames, industrial supports and architectural steelwork. The name identifies a profile family, not a safe load rating; final selection must follow the approved drawing, BOQ, project standard and responsible engineer’s calculations.
02
What does narrow parallel flange mean?
The designation identifies a geometry within the NPB Beams family; it is not a material grade, strength class or load rating. Read it only with the applicable dimensional table and project standard, then confirm depth, flange width, web and flange thickness, root radius where relevant, and unit mass.
03
Which NPB sizes, flange widths and weights are published?
The live page shows NPB 100 to NPB 300 in the published chart, with 50 mm to 90 mm flange width and 8.3 kg/m to 41.5 kg/m. These are catalogue values rather than confirmation of ready stock. Quote the exact section designation, dimensional standard, material grade, length and quantity, and verify the selected row against the approved project documents.
04
How is an NPB beam different from a W beam?
NPB Beams has its own dimensional and mass series. A similar nominal depth in another family can have different flange width, thickness, radii, mass and section properties. Compare recognised section tables and approved calculations; never treat related profile names as automatic equivalents.
05
When is an NPB profile considered in a structural design?
An engineer may consider NPB Beams when its documented geometry, section properties, material grade and connection arrangement satisfy the project calculations and specification. Reduced mass, flange width or space efficiency can inform comparison, but cannot replace checks for strength, stability, deflection, buckling and fire requirements.
06
Can an NPB size be identified from depth alone?
State the full NPB Beams designation, dimensional standard, material grade and grade standard, length, piece quantity or tonnage, finish, MTC, inspection and drawing reference. Depth or flange width alone is insufficient because similar headline dimensions can have different thicknesses, radii, mass and section properties.
07
How should NPB web and flange thickness be checked?
No substitution or structural selection should be made from profile name, span, flange width or unit weight alone. Capacity depends on loads, combinations, span, orientation, lateral restraint, buckling, deflection, connections, fire requirements and the design code. Any change from NPB Beams requires revised calculations and written approval.
08
Can an NPB profile be substituted for an IPE beam?
No substitution or structural selection should be made from profile name, span, flange width or unit weight alone. Capacity depends on loads, combinations, span, orientation, lateral restraint, buckling, deflection, connections, fire requirements and the design code. Any change from NPB Beams requires revised calculations and written approval.
09
How is the NPB Beams price per kg calculated?
Do not publish a fixed current NPB Beams price per kg. The rate changes with steel grade, section mass, quantity, length, finish, market date and supply route. Send the exact designation, standard, total tonnage and delivery postcode for a dated quotation, then confirm GST, freight and fabrication inclusions.
10
Can a bulk NPB Beams supplier quote a dated tonne rate?
A current NPB Beams price per tonne can be quoted for a defined requirement. State the exact section, material grade and standard, length, pieces or tonnage, finish, MTC, inspection and destination. Compare offers on the same weight basis and verify tax, freight, cutting, packing and documentation terms.
11
Why may two NPB Beams supplier quotations differ?
The landed cost of NPB Beams depends on grade, section availability, unit mass, order mix, total tonnage, length, cutting, drilling, coating, testing, inspection, packing and transport. An uncommon designation or mixed small quantities may price differently from one repetitive bulk section.
12
How is the minimum order quantity confirmed for NPB Beams?
The live page states a minimum order quantity of 1 tonne. Confirm how MOQ applies when the enquiry mixes sections, grades, special lengths, finishes or inspection requirements. Provide the piece count and calculated tonnage for every line item so commercial feasibility can be reviewed accurately.
13
How should current NPB Beams stock availability be checked?
Do not assume every NPB Beams designation, grade and length is ready stock. Availability should be confirmed against the exact specification, quantity and enquiry date. If timing matters, state the required date and ask whether the quotation is based on stock, incoming material or a reviewed supply requirement.
14
Can heat traceability and an MTC be requested for NPB Beams?
Request the MTC for NPB Beams at the enquiry stage, stating certificate type, grade standard, heat traceability and project format. Check that the certificate matches the supplied markings, dimensions and product form. A generic document does not establish compliance with every structural, toughness or coating requirement.
15
What should third-party inspection cover for NPB Beams?
Inspection for NPB Beams should cover identification, dimensions, web and flange thickness, length, straightness, surface condition, quantity, marking and MTC traceability. For third-party inspection, specify the agency, stage, hold points, acceptance criteria and required reports before ordering.
16
Can fabrication drawings be included with a NPB Beams enquiry?
Cutting, drilling or fabrication of NPB Beams can be reviewed against an approved drawing. Provide cut lengths, hole centres, copes, notches, end plates, weld details, tolerances and piece marks. Connection design, welding procedures and any structural modification remain subject to engineer and fabricator approval.
17
Should hot-rolled or galvanised finish be stated for NPB Beams?
The live page lists hot-rolled, galvanised or customer-specified for NPB Beams. State the required surface condition, coating or galvanising standard, preparation, appearance and inspection. Coating suitability depends on the base material, fabrication sequence and exposure, and galvanised steel is corrosion-resistant rather than permanently rust-proof.
18
Which industries procure NPB Beams?
NPB Beams are considered for space-conscious structural frames, industrial supports and architectural steelwork. Suitability depends on the exact section properties, material grade, exposure, span, restraints, loads, connections and fire requirements. Final use must follow approved calculations, drawings, BOQ and applicable project standards.
19
Does Ferrite review India-wide and export enquiries for NPB Beams?
Ferrite can review NPB Beams requirements for Mumbai, Navi Mumbai, Maharashtra, nearby states, India-wide supply and export enquiries. Availability and logistics depend on section and quantity. Provide the delivery postcode or destination port, Incoterm, unloading constraints and required date for review.
20
Which information prevents delay in a NPB Beams quotation?
For a fast NPB Beams quotation, send the profile and exact designation, dimensions, material grade, material and dimensional standards, length, pieces, tonnage, finish, make preference, MTC and inspection requirements. Add fabrication drawings, delivery postcode or port, Incoterm and required date where applicable.
