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 Square Bar?
ASTM A36 Square Bar are carbon structural steel square bar ordered to ASTM A36/A36M. The exact side size, grade, standard, supply condition and intended use must be stated because the commercial product name alone does not establish chemical, mechanical, dimensional or heat-treatment requirements.
02
What are the main applications of ASTM A36 Square Bar?
Common applications include structural work, brackets, supports, frames and general fabrication. Suitability depends on the component design, loads, environment, machining allowance, heat treatment and governing code. Final selection must follow the approved drawing, BOQ, end-user specification and responsible engineer’s approval.
03
Which side sizes are listed for ASTM A36 Square Bar?
The live square-bar 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. These published entries are not a guarantee of current stock. Confirm the exact side dimension, grade, length, condition and quantity, particularly when a machining drawing requires an unlisted size or minimum clean-up allowance.
04
How should I specify the size and tolerance for ASTM A36 Square Bar?
State the nominal side dimension in millimetres, across-flat tolerance, corner profile, squareness, straightness and surface condition. For machined parts, add the finished component size and machining allowance. Bright and hot-rolled square bars may have different dimensional expectations.
05
What standard lengths are available for ASTM A36 Square Bar?
The reviewed page does not publish a fixed length range. Availability should be confirmed for the requested square size, grade and quantity. State exact or random length, permissible tolerance, cut-length schedule, end condition and whether each piece must be identified to a drawing item.
06
How is ASTM A36 Square Bar weight per metre calculated?
For a solid steel square bar, theoretical weight in kg/m is approximately side in millimetres squared x 0.00785, using nominal dimensions and a typical steel density. Actual or invoiced weight may differ because of dimensional tolerance, density, scale, length and the agreed commercial basis.
07
Can I get a ASTM A36 Square Bar weight chart?
Yes. The live page provides average kg/m and kg/ft values for listed square sizes. Use them for estimation, then confirm the quotation basis and applicable dimensional tolerances. For engineering-grade or special-condition material, ask whether the supplier uses theoretical or actual weighment.
08
What is the ASTM A36 Square Bar price per kg?
The price per kg requires a dated quotation and varies with grade, square size, quantity, supply condition, finish, testing, cutting, packing, freight and taxes. Heat-treatment condition can be important for engineering grades. Send a complete specification for a comparable rate.
09
How is the ASTM A36 Square Bar price per tonne determined?
Price per tonne depends on the exact grade and standard, size mix, bar length, total tonnage, condition, certification, inspection and destination. Confirm whether cutting, heat treatment, testing, packing, freight and GST are included and check the quotation validity.
10
What is the MOQ for ASTM A36 Square Bar?
The live page states a minimum order quantity of 1 tonne. Actual order acceptance remains subject to the required size, grade, condition and availability. For mixed-size orders, give the piece count or weight for each line item so every size can be reviewed.
11
Is ASTM A36 Square Bar available from ready stock?
Stock must be confirmed for the exact side dimension, grade, standard, length, finish, condition and quantity. A live product page or size chart does not establish immediate availability. State any mill or make preference, MTC requirement, inspection plan and required delivery date.
12
Can an MTC be supplied with ASTM A36 Square Bar?
Request the mill test certificate at enquiry stage and state the required document type. It should identify the material, heat or batch, grade, standard and reported chemistry and mechanical results where applicable. Heat-treatment condition, hardness and traceability requirements should be agreed before ordering.
13
What grade and impact-quality details must be checked for ASTM A36 Square Bar?
Confirm the complete grade, governing standard, section-dependent mechanical requirements, impact-quality suffix where applicable and MTC. Astm a36 is a material specification; dimensional tolerances must be stated separately. Grade substitution or omission of a quality suffix requires engineer and end-user approval.
14
Can ASTM A36 Square Bar be cut, machined, threaded or heat treated?
Processing can be reviewed against the drawing, grade, condition and quantity. Provide cut lengths, tolerances, thread details, machining allowance and required heat treatment or hardness. Final component properties cannot be guaranteed from the bar designation alone; the approved manufacturing route controls the result.
15
Can ASTM A36 Square Bar be replaced with an equivalent grade?
Do not substitute from a web equivalence table alone. Compare full chemistry limits, mechanical properties, section-dependent requirements, delivery condition, hardenability, impact quality, heat treatment and certification. Any alternative requires written approval from the responsible engineer or end user before supply.
16
Can I buy ASTM A36 Square Bar from a supplier in Mumbai or Navi Mumbai?
Ferrite lists its head office in Mumbai and a facility address at Kalamboli, Navi Mumbai. Provide delivery postcode, longest length, total tonnage, unloading constraints and required date so availability and logistics can be reviewed for Mumbai, Navi Mumbai and Maharashtra.
17
Can ASTM A36 Square Bar be supplied across India?
The website states nationwide supply. India-wide enquiries should include the consignee postcode, grade, side size, length, tonnage, packing and delivery schedule. Long-bar freight can materially affect landed price, so compare offers on the same ex-works or delivered basis.
18
Does Ferrite handle export enquiries for ASTM A36 Square Bar?
Export requirements can be reviewed against the requested specification and quantity. Provide destination port and country, Incoterm, grade, standard, side size, length, tonnage, condition, packing, MTC and inspection requirements. Shipping programme and documentation must be confirmed for the specific order.
19
How should quotations from ASTM A36 Square Bar suppliers be compared?
Compare the exact grade, standard, size tolerance, corner condition, length, condition, origin or make if specified, MTC, inspection, cutting, packing, freight, taxes and delivery basis. A lower rate is not comparable if the offered condition, certification or heat-treatment scope differs.
20
What details are needed for a fast ASTM A36 Square Bar quotation?
Send product name, complete grade and standard, square side size, length, piece quantity and total tonnage. Add finish and delivery condition, tolerance, make preference, MTC, inspection or testing, cutting drawing, delivery postcode or destination port, Incoterm and required delivery date.
