Stainless steel omega profile is a cold roll-formed stainless steel section with an Ω (omega)-shaped cross-section, featuring a flat web with two flanged legs that curve outward before returning flat, providing a mechanical self-locking or snap-fit engagement capability. Manufactured from 304 or 316 grade stainless steel, omega profiles deliver structural rigidity combined with ease of installation in modular systems.
Stainless steel omega profiles are used as concealed panel mounting systems, suspended ceiling grid runners, wall cladding support rails, facade bracket clips, skirting board fixings, and as structural trim in modular partition and cladding systems in commercial, hospitality, and healthcare interiors where hidden fixing is preferred.
