Overview
Galvanized Round Steel G550 belongs to high-strength series galvanized sheet, with high requirements for tensile strength and yield strength. Its minimum yield strength is 560Mpa, minimum tensile strength is 650Mpa, and zinc layer thickness is 275g/m2. It has strong corrosion resistance and is mainly used for building structures with high strength requirements, such as Z-shaped steel, C-shaped steel, floor bearing plate, etc. Galvanized round steel is a geometric object made of iron or materials with certain strength and toughness by rolling, extruding, casting, hot galvanizing anti-corrosion profile surface and other processes. Hot dip galvanized round steel is produced by advanced galvanizing process, and its surface is glossy and durable. Galvanized round steel products have been used in many fields. The advantage of hot-dip galvanized round steel is that it has a long anti-corrosion life and has been a popular anti-corrosion treatment method to adapt to a wide range of environments. It is widely used in electric power tower, communication tower, railway, highway protection, street light pole, marine components, building steel structure components, substation ancillary facilities, light industry, etc. Product name G550 Galvanized Round Steel Diameter 16-250mm or Customized Length Customized Advantages Dia 10.00 mm, cold drawn, on request also ground; ISO h9 Tighter tolerances on request Out of roundness standard: ½ of diameter tolerance Finish Line Straightening machines Milling and chamfering devices Surface control (Circograph, Circoflux) Ultrasonic control device Antimixing control - spectrotest devices Packaging, marking Standard AiSi, ASTM, BS, GB, JIS, EN,AS ETC.
