SG295 Steel Coil – Manufactured to JIS G3116 Standard for Safe Gas Cylinder Production
Are you manufacturing LPG, CNG, or industrial gas cylinders for markets like Pakistan or the Middle East? You need a reliable steel coil that meets JIS G3116 SG295 standards with guaranteed mechanical properties and complete import documentation.
We supply SG295 hot-rolled coils with full mill test certificates (MTC), designed specifically for welded gas cylinders up to 500 liters.
Why SG295 for Gas Cylinders? And Why Source from Us?
SG295 is a hot-rolled steel grade specified under JIS G3116, the Japanese standard for steel sheets, plates, and strips used in welded gas cylinders . With minimum yield strength of 295 MPa and tensile strength of 440 MPa, it offers the ideal balance of strength and formability for manufacturing LPG, CNG, and industrial gas cylinders up to 500 liters .
Over the past decade, we've specialized in gas cylinder steels, supplying to manufacturers across Asia, the Middle East, and specifically Pakistan. We know that importing gas cylinder materials into Pakistan requires more than just good steel – it requires complete documentation for DOE licensing, third-party inspection readiness, and clear communication with Pakistani regulators . That's exactly what we deliver.
Technical Specifications – JIS G3116 SG295
| Parameters | Numerical value | Characteristics |
| Yield strength | ≥295 MPa | Ensures that the gas cylinder can withstand the rated working pressure and has sufficient safety margin |
| Tensile strength | ≥440 MPa | Provides sufficient strength reserve to cope with unexpected pressure fluctuations |
| Elongation | ≥26% | Ensures the cold processing forming performance, and the gas cylinder head stamping is less likely to crack |
| Carbon content | ≤0.20% | Excellent welding performance, reducing the risk of weld crack |
| Manganese content | ≤1.00% | Ensures strength while maintaining good toughness |
| Phosphorus and sulfur content | ≤0.030% | High purity, avoiding hot brittleness and cold brittleness |
Flexible Supply – From Stock to Custom Orders
Stock availability: Regularly stocked with ready-to-use thicknesses (3.0 - 6.0mm) and widths (1000 - 1500mm), sufficient to meet urgent orders
Custom production: Special thickness (1.2 - 12.0mm) can be customized through rolling. The production cycle is 20 - 25 days.
Flexible weight: Acceptable for small batch trial orders (1-2 rolls), and also supports bulk purchase of the entire furnace.
Packaging specialty: Standard export ocean shipping packaging - bare coil bundling + anti-rust oil + waterproof lining + steel band reinforcement, ensuring no rust during long-distance ocean shipping.
SG295 vs SG255 vs SG325: Which Steel Grade is Right for Your Gas Cylinder?
| Grade | Min. Yield Strength (MPa) | Min. Tensile Strength (MPa) | Typical Application | Our Recommendation |
|---|---|---|---|---|
| JIS G3116 SG255 | ≥255 | ≥400 | Small, low-pressure cylinders (fire extinguishers, portable tanks) | Cost-sensitive projects with lower working pressure. |
| JIS G3116 SG295 | ≥295 | ≥440 | Standard LPG, CNG, and industrial gas cylinders (Most popular) | Best balance of strength, formability, and value. |
| JIS G3116 SG325 | ≥325 | ≥490 | High-pressure, large-capacity, or severe service cylinders | Applications requiring a higher safety margin or special approvals. |
How to Arrange PSI Inspection (SGS/BV) for Your SG295 Steel Coils
For imports requiring Pre-Shipment Inspection (e.g., Pakistan, Kenya), we simplify the entire process with major inspection agencies.
We fully cooperate with SGS, Bureau Veritas (BV), or Intertek for a seamless PSI process:
Notify at Order: Mention "PSI inspection required" in your inquiry or contract.
Agency Confirmation: Your local SGS/BV office contacts our local office in China.
Factory Inspection: The inspector visits our facility to:
Check visual appearance and dimensions.
Take samples on-site.
Witness mechanical property tests.
Report Issued: The agency issues the official PSI report for your customs clearance and DOE (Department of Explosives) license.

| Pakistan | 7208.3890 | Other hot-rolled iron/non-alloy steel coil, thickness ≥4.75mm | Certificate of Origin, MTC, PSI report (usually required) |
| India | 7208.2710 | Hot-rolled coil, not clad, plated or coated | BIS certification (specific cases), COO |
| UAE | 7208.3990 | Other hot-rolled iron/non-alloy steel coil | COC (Certificate of Conformity), MTC |
| Vietnam | 7208.2799 | Flat-rolled, hot-rolled, not in coils | Form E (AFTA), MTC |
SG295 Minimum Order Quantity (MOQ), Samples & Lead Time
| Order Type | MOQ | Lead Time (after deposit) | Best For |
|---|---|---|---|
| Stock / Sample Order | 1 coil (approx. 3-5 tons) | 3-5 working days | Emergency restocking, material testing, small batch trial |
| Custom Rolling Order | 20 tons (one furnace batch) | 20-25 days | Non-standard thickness (1.2 - 12.0mm), batch production |
| Full Furnace Bulk | Negotiate per furnace lot | Priority scheduling | Large manufacturers, long-term supply |
