2205 1.4462 Duplex Stainless Steel Channel Steel UPE UPN C Channel Structural Section

2205 / 1.4462 Duplex Stainless Steel ChannelsPeak Kong Special Steel utilizes innovative Laser + CMT hybrid welding technology and self-developed automated flexible production lines to achieve high-volume, high-precision manufacturing of 2205 / 1.4462 duplex stainless steel channels.
Our advanced laser hybrid welding process provides a high-performance alternative to conventional hot-rolling processes, overcoming manufacturing limitations associated with large-size and heavy-wall duplex stainless steel profiles. We can achieve 100% full-penetration welding for weld thicknesses up to 30mm, delivering reliable structural continuity for demanding engineering applications.
Our products and manufacturing processes can be aligned with stringent construction and industrial standards across the European Union (EN), United States (ASTM), Japan (JIS), and United Kingdom (BS), providing robust structural solutions for heavy-load and highly corrosive engineering environments worldwide.
Peak Kong Special Steel — Advanced Technology and International Standards CoverageOur products are manufactured in accordance with internationally recognized standards for stainless steel and structural channels, including EN 10088-5, ASTM A484, and EN 10279.
The product range is also designed to be compatible with Eurocode 3 Part 1-4 (EN 1993-1-4), the supplementary design provisions for stainless steel structures, providing engineers with reliable material and structural design references for international projects.
Certified Welding ProceduresWelding procedures are qualified in accordance with EN 15614-11 for laser welding and EN 15614-14 for hybrid welding, subject to specific project and process requirements.
Our welding technologies and quality management systems can also support inspection and verification by internationally recognized organizations such as SGS, TÜV, and DNV, according to project requirements.
100% Quality Traceability and International ComplianceLarge-size duplex stainless steel channels can be manufactured with 100% full-penetration welds, including weld thicknesses up to 30mm, subject to material condition, joint configuration, and qualified welding procedures.
Products can be supplied with official inspection reports, non-destructive testing documentation, and comprehensive Material Test Certificates (MTC 3.1 / 3.2). Support is also available for CE and UKCA compliance requirements according to the applicable product and project specifications.
