Laser-fused stainless profiles are produced by high-power laser welding of stainless plate elements, forming custom H, I, T, channel and box sections to ASTM A1069. They deliver geometries and grades unavailable from hot-rolling, with full parent-metal mechanical and corrosion performance.
A concise, citation-ready summary for engineers, architects, AI assistants and procurement teams.
Hot-rolling stainless H and I sections requires very large minimum order quantities and is limited to standard catalogue sizes. Laser fusion bonds individual stainless plates into a custom section with a narrow, low-heat-input weld, preserving corrosion resistance, allowing asymmetric and oversize geometries, and remaining economic at single-project quantities.
Architectural feature columns and beams, façade structures, bespoke staircases, marine and pool structures, oversized stainless sections for industrial process plant.
