S275JR S355JR hot dipped galvanized pipe for Compressed Air

S275JR and S355JR are European standard steel materials, suitable for hot-dip galvanized pipes for compressed air applications. ‌
S275JR and S355JR are both European standard steel materials. They are both low-alloy high-strength structural steels with high yield strength and tensile strength, suitable for various engineering and construction applications. These two materials of hot-dip galvanized pipes are used in compressed air systems to provide good corrosion resistance and mechanical properties, ensuring stable operation and long-term use of the system.
