FAQ
Sheet Metal — Common Questions
Grade selection, pricing, HSN codes, and procurement — answered from the production floor.
What is sheet metal?
Sheet metal is flat metal formed by rolling into thin, flat pieces. In India, sheet metal is produced to IS standards — HR IS 2062 for hot rolled structural steel, CR IS 513 for cold rolled precision steel, and GI IS 277 for galvanized zinc-coated sheet. Standard thicknesses range from 0.3mm to 6mm. Sheet metal is used in automotive panels, electrical enclosures, structural fabrication, LED lighting housings, HVAC ducting, and industrial furniture.
What is the HSN code for sheet metal in India?
HSN codes for sheet metal: HR IS 2062 (Hot Rolled flat-rolled steel) HSN 7208, GST 18%; CR IS 513 (Cold Rolled flat-rolled steel) — HSN 7209, GST 18%; GI IS 277 (Galvanized, clad, coated or plated steel) HSN 7210, GST 18%; SS 304/316 (Stainless Steel flat-rolled) — HSN 7219/7220, GST 18%. Fabricated sheet metal components (articles of iron and steel) fall under Chapter 73 — HSN 7308/7326. Confirm with your CA or GST consultant for transaction-specific classification. Aero Enterprises invoices with full HSN compliance on every consignment.
What is the difference between HR and CR sheet metal?
HR (Hot Rolled) sheet is rolled above 900°C — rougher surface, looser thickness tolerance, lower cost. Correct for structural frames, base plates, heavy weldments, and applications where surface finish is secondary to strength. CR (Cold Rolled) sheet is rolled at room temperature after hot rolling — tighter thickness tolerance, smooth scale-free surface, higher formability. Correct for precision components, cosmetic enclosures, deep draw stampings, and powder-coated parts. CR IS 513 costs approximately ₹4–8/kg more than HR IS 2062 depending on gauge and grade.
What is sheet metal price per kg in Vasai and Mumbai?
Indicative sheet metal prices ex-Vasai (subject to mill rate revision): MS HR IS 2062 primary — ₹54–62/kg; CR IS 513 primary — ₹58–68/kg; GI IS 277 primary (120 GSM) — ₹75–90/kg; SS 304 primary — ₹180–220/kg; Secondary MS sheet — ₹45–54/kg. Prices vary by gauge, quantity, and market conditions. Contact Aero Enterprises Unit II Dhumal Nagar for current volume pricing and MTC documentation.
What are the CR IS 513 sub-grades and which should I specify?
CR IS 513 has four sub-grades: CQ (Commercial Quality) — simple bending and holes, most economical; DQ (Drawing Quality) — moderate forming and draw operations; DDQ (Deep Drawing Quality) — deep draw stampings with severe geometry; EDD (Extra Deep Drawing Quality) — extreme stretch forming. Specifying CQ for a DDQ operation produces cracking at the press. Specifying DDQ for a CQ application wastes cost per kilogram. Aero Enterprises performs grade selection review for every new component — contact Unit I for DFM consultation before procurement.
What is sheet metal gauge and how does it convert to mm?
Sheet metal gauge is a legacy number system where higher numbers indicate thinner material. Common mild steel conversions (SWG): 20 gauge = 0.9mm; 18 gauge = 1.2mm; 16 gauge = 1.5mm; 14 gauge = 2.0mm; 12 gauge = 2.5mm; 10 gauge = 3.0mm. In India, IS standards specify thickness in millimetres — commercial supply is quoted in mm. Gauge numbers are used in field reference only.
What is the difference between a sheet and a plate in steel?
In steel supply, sheet refers to flat-rolled steel up to 6mm thick in standard sizes — typically 8×4 ft (2438mm × 1219mm) in India. Plate refers to flat-rolled steel above 6mm, supplied in larger dimensions for heavy structural, pressure vessel, and machinery applications. Sheet is the correct term for fabrication applications below 6mm. Aero Enterprises Unit II supplies sheet in standard 8×4 ft across HR, CR, GI, and SS grades.
What is the difference between primary and secondary sheet metal?
Primary sheet metal is produced directly from iron ore at integrated mills (JSW, TATA, SAIL) with a verifiable Mill Test Certificate traceable to the producing mill — it conforms to IS standard chemical composition and mechanical properties. Secondary sheet is re-rolled from steel scrap — it may look identical but does not have primary mill MTC traceability and may not conform to IS standard mechanical properties. For structural, automotive, and OEM applications requiring grade conformity, primary mill certified material is mandatory. Aero Enterprises Unit II stocks JSW and TATA primary certified material with MTC on every consignment.
What is TATA metal sheet and how is it priced?
TATA metal sheet refers to flat-rolled steel coils and sheets produced at Tata Steel's Jamshedpur and Kalinganagar plants — one of India's primary integrated steel mills. TATA-certified material comes with a Mill Test Certificate confirming IS standard conformity. TATA HR IS 2062 and CR IS 513 are benchmark primary grades for OEM supply chains. Pricing tracks JSW and TATA mill rack rates, revised monthly. Aero Enterprises Unit II Dhumal Nagar, Vasai is a certified TATA and JSW primary stockist. Contact for current pricing.
What types of sheet metal are available at Aero Enterprises Vasai?
Aero Enterprises Unit II Dhumal Nagar, Vasai East stocks: HR IS 2062 (Hot Rolled), CR IS 513 CQ/DQ/DDQ (Cold Rolled), GI IS 277 (Galvanized — 120 to 180 GSM), SS 304 and SS 316 (Stainless Steel), HRPO/PO (Pickled and Oiled), and Mild Steel coils and sheets in primary and secondary grades.
