Duplex 2205 (1.4462) is a high-strength stainless steel that combines roughly double the proof strength of 304 with outstanding chloride and stress-corrosion resistance. Its dual austenitic-ferritic microstructure makes it the grade for marine, chemical and high-load structures where 316L is not enough. ULAMEX supplies duplex 2205 in sheet, plate, bar, profile and pipe, to EN…

304 and 316 are the two most specified stainless steel grades, and the choice between them comes down to corrosion environment. 304 (1.4301) is the general-purpose grade; 316 (1.4404) adds molybdenum for chlorides, marine and chemical exposure. ULAMEX stocks both, plus 304L, 316Ti, ferritic 430 and duplex 2205, as profiles, sheet, rods and pipes, to…

EN 10219 is the European standard for cold-formed welded structural hollow sections. It covers rectangular (RHS), square (SHS) and circular (CHS) hollow sections in weldable structural grades such as S235JRH, S275J2H and S355J2H. This guide explains what EN 10219 covers, the section types and grades, the mechanical and impact properties, how it differs from the…

Aluminium profiles are extruded sections used as the structural and architectural building blocks of fabrication. ULAMEX supplies the full range of standard profiles, angle, channel, T-slot, flat bar, T-bar, gate profiles and tube, in the EN AW-6060, 6063 and 6082 alloys, in standard 3,000 and 6,000 mm lengths. This guide covers the profile types, the…

EN AW is the European designation system for wrought aluminium alloys under EN 573-3. The four-digit number after it identifies the alloy and its main alloying elements. ULAMEX stocks the most widely specified EN AW grades for industry and construction: 6060, 6063 and 6082 for profiles and structural sections, 5083 and 5754 for marine and…
