Q195 Galvanized  Round Steel

Q195 Galvanized Round Steel refers to hot-rolled round bars made of Q195 carbon steel (minimum yield strength 195 MPa) that are subsequently hot-dip galvanized to provide a protective zinc coating against corrosion. It is widely used in applications requiring good formability, moderate strength, and long-term corrosion resistance, such as in light structural components, fencing, fasteners, and various hardware used in construction, utility, and general manufacturing industries. Product name Q195 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 (Q195): Yield Strength ≥ 195 MPa, Tensile Strength: 315-430 MPa (as-rolled). Note: The stated 570-820 MPa is incorrect for Q195. Bar Processing Hot-rolled (as base material). Further processing: peeling, turning, straightening, cutting as required. Application Light structural components, fencing, fasteners, and general hardware in construction, utility, and manufacturing. (The listed precision machining applications are atypical for standard hot-dip galvanized Q195 round bars.)
