Load-bearing walls
Vertical studs and panel tracks, selected for loads, openings and wall height.
LGS profiles
LGS profiles
From C50 to C250, every section is engineered, punched, cut and marked for its structural function.
zinc-magnesium coating · S350GD
The steel behind our profiles
Cold-formed S350GD steel protected by a zinc-aluminium-magnesium zinc-magnesium coating coating. Grade, thickness and coating are selected from the structural design and exposure.

One profile family, three structural functions.
C150 · C200 · C250
Floors
Horizontal joists engineered for span, permanent and imposed loads, and deflection.
C89
Roof trusses
Profiles assembled as trusses to span between supports and resist snow, wind and roofing loads.
Production details
Digitally controlled operations
Operations come directly from the production file to speed assembly, route services and avoid manual rework.
Screw Hole
Accurate connection with limited build-up around the screw.
Service Hole
35 × 70 mm opening for electrical and data cables.
Index Hole
13 mm hole to bolt two profiles back-to-back.
Web Notch
Web opening allowing another profile to pass through.
Lip Notch
Local lip cut to fit two profiles together.
Utility Service Hole
120 × 140 mm opening for ducts and conduits on C200 and C250 profiles.
Engineering data
