Q235 Galvanized  Round Steel

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.

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.

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.)
