PRODUCT DETAILS
Q235 Galvanized Round Steel refers to hot-rolled round bars made of Q235 carbon steel (minimum yield strength 235 MPa) that are subsequently hot-dip galvanized to provide a protective zinc coating against corrosion. This process significantly extends the service life of the steel in exposed environments.
It is widely used in applications requiring both structural strength and long-term corrosion resistance, such as in power transmission towers, communication towers, highway guardrails, street light poles, marine components, and various structural fasteners and components in construction and utility industries.
Q235 Hot-Dip Galvanized Round Steel Bar Specifications
| Product name | Q235 Hot-Dip Galvanized Round Steel Bar |
| Diameter | 6-250mm or Customized |
| Length | Customized |
| Advantages | Standard tolerance as hot-rolled round bar (e.g., h11, h12 per ISO). Cold drawn available for tighter tolerances (e.g., h8, h9). |
| Finish Line | Straightening, cutting, surface inspection, anti-mixing control, packaging and marking. |
| Standard | GB/T 699 (for base steel), GB/T 342 (for hot-rolled round bar). Hot-dip galvanizing per relevant coating standards. |
| Surface Treatment | Hot-Dip Galvanized |
| Mechanical Property | Base Steel (Q235): Yield Strength ≥ 235 MPa, Tensile Strength: 370-500 MPa (as-rolled). Note: The stated 570-820 MPa is incorrect for Q235. |
| Bar Processing | Hot-rolled (as base material). Further processing: peeling, turning, straightening, cutting as required. |
| Application | Structural components, bolts, shafts, studs, and fasteners in construction, utility, marine, and industrial sectors requiring corrosion protection. (The listed applications for precision machining are more typical of bright or cold-drawn bars, not standard hot-dip galvanized round bars.) |
Packing and shipping
Our company has passed ISO9001 quality management system certification, Our Mill product with CE/EN10204 / ASTM/Classification society certificate/CASO/BIS etc certificate.All the customers give good appreciation to our products.We are glad to be your good partner.
Application Areas
Steel is widely used in steel structure workshops, bridge frames, main structures of high-rise buildings, and infrastructure construction (such as highways, oil and gas pipelines). Its high strength properties ensure load-bearing stability and seismic performance. In ship manufacturing, steel is used to build hull structures, decks, and internal components. Hot-rolled coils rely on their load-bearing capacity to adapt to harsh environments.
