Product Overview – S355 Steel Pipes
S355 Pipes are high-strength structural carbon steel pipes manufactured in accordance with EN 10025 standards for demanding engineering, infrastructure, offshore, oil & gas, construction, and industrial applications. Known for their excellent mechanical strength, superior weldability, and outstanding structural performance, S355 steel pipes are one of the most widely specified materials for heavy-duty projects worldwide.
Available in Seamless, ERW (Electric Resistance Welded), EFW (Electric Fusion Welded), and LSAW welded constructions, S355 pipes provide exceptional durability and reliability under high mechanical loads and challenging operating conditions. Their excellent fabrication characteristics make them ideal for structural steelwork, industrial piping systems, bridges, marine structures, pressure applications, heavy engineering, and renewable energy projects.
We supply and export a complete range of S355 Pipes in grades including S355JR, S355JO, S355J2+N, S355JR+N, S355J2G3, and S355J2, serving EPC contractors, construction companies, engineering consultants, oil & gas operators, and industrial manufacturers throughout the UAE, Saudi Arabia, Qatar, Oman, Kuwait, India, and international markets.
