Hot galvanized steel pipe refers to hot-dip galvanized steel pipe, which is galvanized on the surface of ordinary steel pipe to form a zinc layer, which can protect the steel pipe from corrosion and extend the service life of the steel pipe.
Hot dip zinc coated steel pipe is made of Q195, Q235, Q345, etc., with a thickness between 2.75mm - 6mm, and a length of 12m, 6m, 6.4m, etc. The length can also be customized. The surface is galvanized, and the galvanized layer can provide good anti-corrosion protection for the steel pipe.
Q235B and Q355B are two common steel grades. Their applications in galvanized steel pipes have different characteristics and uses. If higher strength and better mechanical properties are required, Q355B is a better choice; if the strength requirements are not high and cost considerations are more, Q235B is more economical and applicable.
A36 A53 GradeB Galvanized steel pipe is a galvanized steel pipe that meets specific standards. Among them, A36 is a common carbon structural steel standard with good strength and toughness; A53 GradeB is a standard for seamless and welded steel pipes established by the American Society for Testing and Materials (ASTM). GradeB means that the grade of the steel pipe is B, which usually has higher quality and performance. This steel pipe is galvanized to form a layer of zinc coating on the surface, which can effectively prevent the steel pipe from rusting and corrosion and extend its service life.
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.
