FAQs — ASTM A36 Flat Bars

ASTM A36 Flat Bars: Frequently Asked Questions

Straight answers on sizes, thickness, weight, grades, MTC, pricing and ordering — so your enquiry is specification-ready before you send it.

01
What is ASTM A36 Flat Bars?
ASTM A36 Flat Bars is a carbon structural steel flat bar specified to ASTM A36/A36M. ASTM A36 is a material specification; dimensions and tolerances must be stated separately where the order requires them. Buyers should state the intended application, width, thickness, length, quantity and governing specification so the requirement can be checked without assuming that every flat bar is interchangeable.
02
Which ASTM A36 Flat Bars sizes are shown on the Ferrite page?
The live size chart lists 10 x 10, 12 x 12, 14 x 14, 16 x 16, 17 x 17, 20 x 20, 25 x 25, 32 x 32, 40 x 40, 42 x 42, 50 x 50, 53 x 53, 56 x 56 and 63 x 63 mm. Treat these as the published chart entries, not a guarantee of current stock. Confirm the required width, thickness, length, grade and tonnage at the enquiry stage, particularly where the drawing uses a size outside the chart.
03
How should width and thickness be written when buying ASTM A36 Flat Bars?
Write the flat size as width x thickness in millimetres and add the required length. Avoid sending only one dimension or an ambiguous “size”. For a fast quotation, include ASTM A36 Flat Bars, the full size, grade or standard, number of pieces, total tonnage, finish and delivery postcode.
04
What standard lengths are available for ASTM A36 Flat Bars?
The reviewed page does not publish a fixed standard-length range. Availability should therefore be confirmed for the requested size, grade and quantity. State the exact bar length, permissible length tolerance, whether random lengths are acceptable, and whether cut lengths must follow an approved cutting list or fabrication drawing.
05
How is ASTM A36 Flat Bars weight per metre calculated?
For a rectangular steel flat, theoretical weight in kg/m is approximately width (mm) x thickness (mm) x 0.00785. This uses a nominal steel density and nominal dimensions. Procurement weight should be checked against the applicable standard, permitted rolling tolerance, actual length and the supplier’s documented basis of invoicing.
06
Can I get a ASTM A36 Flat Bars weight chart?
Yes, the product page provides average kg/m and kg/ft entries for its listed sizes. Use the chart for estimation and BOQ planning, then confirm the quotation basis. For an unlisted size, calculate theoretical mass from width and thickness and allow for the applicable dimensional and mass tolerances.
07
What is the ASTM A36 Flat Bars price per kg?
The price per kg is quotation-based rather than a fixed web price. It can change with steel input cost, grade, section size, quantity, finish, testing, cutting, freight and taxes. Send the complete specification and delivery location to obtain a dated, comparable quotation.
08
How is the ASTM A36 Flat Bars price per tonne determined?
Price per tonne depends on ASTM A36/A36M together with the required dimensional specification, size mix, total tonnage, length, finish, documentation, inspection and destination. Ask whether freight, packing, GST, cutting and inspection are included. A useful quotation should identify its validity period and the exact material specification offered.
09
What is the MOQ for ASTM A36 Flat Bars?
The live page states a minimum order quantity of 1 tonne. Actual acceptance remains subject to the requested size, grade, finish and current availability. For mixed-size orders, provide the quantity of each line item so the supplier can review whether the total and individual quantities are workable.
10
Is ASTM A36 Flat Bars available from stock?
Stock must be confirmed for the required size, grade, length, finish and quantity. A product listing or size chart does not prove immediate availability. Buyers should also state any mill or make preference, MTC requirement and required delivery date because these factors may affect sourcing and allocation.
11
Can an MTC be supplied with ASTM A36 Flat Bars?
Request the mill test certificate at the enquiry stage and specify the required certificate type or project format. The document should correspond to the supplied material and state the applicable grade or standard, heat or batch identification and reported test results. Any third-party review must be agreed before order placement.
12
What inspection documents should be requested for ASTM A36 Flat Bars?
The document package should match the contract and may include the MTC, commercial packing details, dimensional inspection records or other agreed certificates. Do not assume every document is standard. State the inspection agency, witness or hold points, acceptance criteria and document submission timing in the purchase enquiry.
13
Can ASTM A36 Flat Bars be replaced with another grade?
Grade substitution should not be made from a web equivalence table alone. Compare the full governing standards, thickness-dependent yield and tensile requirements, chemistry, impact quality, weldability, delivery condition and certification. Any alternative must be approved in writing by the responsible engineer, end user or project authority before supply.
14
Can ASTM A36 Flat Bars be cut, drilled or fabricated?
Cutting, drilling or other fabrication can be reviewed against the drawing and quantity, but capability should be confirmed before ordering. Provide a dimensioned drawing, hole sizes and locations, edge requirements, permissible tolerances, piece identification and whether fabrication must occur before coating. Final structural details require engineer approval.
15
Which industries use ASTM A36 Flat Bars?
Common buyer applications include building frames, brackets, supports, walkways, machinery components and general fabrication. Suitability depends on the selected grade, dimensions, delivery condition, environment and design calculations. The product name alone should not be used as a structural load recommendation; final selection must follow the approved drawing, BOQ and responsible engineer’s approval.
16
Can I buy ASTM A36 Flat Bars from a supplier in Mumbai or Navi Mumbai?
Ferrite Structural Steels Pvt Ltd lists its head office in Mumbai and a facility address at Kalamboli, Navi Mumbai. Buyers in Mumbai, Navi Mumbai and Maharashtra should provide the delivery postcode, unloading constraints, size-wise quantity and required date so logistics and availability can be reviewed accurately.
17
Can ASTM A36 Flat Bars be supplied across India?
The website states nationwide supply. India-wide enquiries should include the destination postcode, consignee details, total tonnage, bar length, packing expectations and delivery schedule. Freight and transit planning can vary materially for long steel products, so compare quotations on the same delivered or ex-works basis.
18
Does Ferrite handle export enquiries for ASTM A36 Flat Bars?
Export requirements can be reviewed against the requested specification and quantity. Provide the destination country and port, Incoterm, packing requirement, grade and standard, length, tonnage, inspection requirement and documentation list. Availability, export packing, shipping terms and delivery programme should be confirmed for the specific enquiry.
19
How should I compare quotations from ASTM A36 Flat Bars suppliers?
Compare the exact grade and standard, dimensions, tolerance basis, length, quantity, finish, make or mill if specified, MTC, inspection, packing, freight, taxes, delivery basis and quotation validity. A lower rate is not comparable if the offered material, documents or logistics scope differs from the BOQ.
20
What information is needed for a fast ASTM A36 Flat Bars quotation?
Send the product name, width x thickness, grade, standard, length, piece quantity and total tonnage. Add finish or coating, make preference, MTC and third-party inspection needs, cutting drawing, delivery postcode or destination port, Incoterm for export and required delivery date. Mention the BOQ item reference where applicable.
