Q195 is a widely used low-carbon structural steel grade in the Chinese GB/T700 standard system. Its mechanical properties, chemical composition, and manufacturing purpose make it comparable—but not identical—to several international steel grades. Here’s how Q195 aligns with equivalents in other standards:
| Standard | Equivalent Grade | Notes |
| ASTM (USA) | A1008 (Commercial Quality – CS Type A) | Closest in application and carbon content. However, A1008 is typically used for cold-formed steel, and detailed specs may differ. |
| JIS (Japan) | SPCC (Commercial Cold Rolled Steel) | SPCC and Q195 are commonly used interchangeably for low-strength, non-critical applications like stamping, household appliances, and automotive panels. |
| EN (Europe) | DC01 (EN 10130) | A cold-rolled low-carbon steel grade used for forming applications. Similar tensile strength and yield point to Q195. |
Note: Although these grades are functionally similar, always verify mechanical properties and chemical composition before substitution.
| Element | Q195 | SPCC | DC01 |
| C | ≤ 0.06% | ≤ 0.08% | ≤ 0.12% |
| Mn | ≤ 0.35% | ≤ 0.45% | ≤ 0.60% |
| P | ≤ 0.035% | ≤ 0.030% | ≤ 0.045% |
| S | ≤ 0.035% | ≤ 0.030% | ≤ 0.045% |
Q195 has the lowest carbon and manganese content, making it softer and more formable—ideal for cold rolling and stamping.
| Property | Q195 | SPCC | DC01 |
| Yield Strength (MPa) | ≥195 | ≥205 | 140–280 |
| Tensile Strength (MPa) | 315–430 | 270–410 | 270–410 |
| Elongation (%) | ≥33 (t≤1.2mm) | ≥28 | 28–36 |
Though Q195 and Q235 are both part of the GB/T 700 standard, there are key differences in chemical composition, mechanical properties, and typical applications.
| Element | Q195 (max) | Q235 (max) |
| C (Carbon) | 0.06–0.12% | 0.12–0.20% |
| Mn (Manganese) | 0.25–0.50% | 0.30–0.70% |
| Si (Silicon) | ≤0.30% | ≤0.30% |
| S, P (Impurities) | ≤0.050% | ≤0.045% |
Summary: Q195 has lower carbon and manganese content, which gives it better ductility but slightly lower strength.
| Property | Q195 | Q235 |
| Yield Strength (MPa) | ≥195 | ≥235 |
| Tensile Strength (MPa) | 315–430 | 375–500 |
| Elongation (%) | ≥33 | ≥26 |
Summary:
| Grade | Typical Uses |
| Q195 | Furniture parts, low-pressure pipelines, wire drawing, cold stamping |
| Q235 | Bridges, structural steel parts, heavy machinery components |
Conclusion: Choose Q195 if you prioritize cold formability and cost; choose Q235 for stronger mechanical performance.
Q195 galvanized sheet refers to Q195 cold rolled steel that has been coated with a layer of zinc via hot-dip galvanizing or electro-galvanizing. The zinc coating improves corrosion resistance, extending the material’s service life.
| Industry | Use Case |
| Construction | Roofing sheets, wall cladding, ducting |
| HVAC | Air ducts, ventilation pipes |
| Furniture | Steel cabinets, enclosures, bed frames |
| Automotive | Inner panel structures, support frames |
| Agriculture | Grain silos, steel fencing, sheds |
Galvanized Q195 combines the formability of low carbon steel with the durability of a zinc finish, making it ideal for both indoor and outdoor usage.

Both Q195 cold rolled coil and Q195 sheet refer to the same material in different packaging formats. Here’s a quick comparison:
| Format | Description | Use Case |
|---|---|---|
| Coil | Continuous roll, easier to process in factories | Mass production, slitting, stamping |
| Sheet | Flat cut-to-length piece | Small batch, manual fabrication, retail |
If you’re buying in bulk for production lines, Q195 steel coil is more economical and efficient. For lower-volume or custom-size needs, Q195 sheet is the better choice.
Q195 steel offers the perfect balance between cost, cold formability, and weldability, making it an excellent option for a wide range of low-stress applications. Its global equivalents make it adaptable across industries, while the galvanized version extends its utility in corrosive environments.
