Galvanized steel pipe is a steel pipe that has been treated with zinc and has good corrosion resistance. SS400, SS490 and SS540 are steel grades specified in the Japanese Industrial Standard (JIS), representing different tensile strength grades.
S235JR, S275JR, and S355JR are all structural steel grades in the European standard (EN10025). After being galvanized into steel pipes, they have the characteristics of structural steel itself and the anti-corrosion advantages brought by the galvanized layer.
A500 Grade B, C, D Galvanized Steel Pipe is a high-quality square tube produced according to the American Standards Association (ASTM) A500 standard and is widely used in building structures, machinery manufacturing and other fields.
Q235B and Q355B galvanized round pipes are two commonly used types of steel, which differ in composition, mechanical properties and application areas.
A36 A53 Grade B Galvanized Round Pipe is a round steel pipe that has been hot-dip galvanized.A36 and A53 Grade B are two common steel grades. A36 is a low carbon steel with good mechanical properties and welding properties. A53 Grade B is a seamless steel pipe suitable for conveying gases and liquids. These steel pipes usually meet ASTM (American Society for Testing and Materials) standards, such as ASTM A36 and ASTM A53.
SS400, SS490 and SS540 are carbon structural steels of different strength levels, which are widely used in construction, bridges, machinery manufacturing and other fields. Galvanized round pipes are round pipes made of these steels after galvanizing, which have good corrosion resistance.
