Light Gauge Steel (LGS) Sections — C and U Profiles for Steel Framing
Steeling.net supplies light gauge steel (LGS) framing sections from Turkish manufacturers for non-load-bearing partition walls, internal framing, prefabricated building systems, and modular construction. Our LGS range includes cold-formed C sections (studs) and U sections (tracks and runners) designed for drywall, drylining, and light steel frame (LSF) construction.
All profiles are produced from hot-dip galvanized steel coil (Z140–Z275) and meet EN 14195 and EN 1993-1-3 requirements. Custom depths, thicknesses, and lengths available — free quote for project quantities.

LGS Profile Types
LGS C Section (Studs)
Vertical studs for partition and load-bearing stud walls. Standard widths: 50, 70, 100, 150 mm. Thickness: 0.5 – 2.0 mm.
LGS U Section (Tracks)
Floor and ceiling track profiles that accept C studs. Matching widths to C section range. Thickness: 0.5 – 1.5 mm.
LGS Section Specifications
| Profile | Width (Web) | Flange | Thickness | Coating |
|---|---|---|---|---|
| C Stud (light gauge) | 50 / 70 / 100 / 150 mm | 35 – 50 mm | 0.5 – 2.0 mm | Z140 / Z275 galvanized |
| U Track (light gauge) | 50 / 70 / 100 / 150 mm | 30 – 40 mm | 0.5 – 1.5 mm | Z140 / Z275 galvanized |
Applications of Light Gauge Steel Framing
- Non-load-bearing interior partition walls (drywall / drylining systems)
- Ceiling grid framing for suspended plasterboard ceilings
- External wall cladding substrate and insulation carriers
- Prefabricated modular room systems and volumetric construction
- Shaft walls and fire-rated wall assemblies
- Hotel and hospitality fit-out and refurbishment projects
Advantages of Light Gauge Steel vs. Traditional Framing
LGS framing is lightweight, dimensionally stable, and non-combustible — making it the preferred choice in fire-rated assemblies and multi-storey construction. Compared to timber stud framing, LGS does not shrink, warp, or rot; it maintains consistent tolerances and is fully recyclable. For large projects, the factory-produced consistency reduces on-site labour and waste.

Frequently Asked Questions
What is the difference between LGS C and U sections?
C sections (studs) are the vertical members in a stud wall — they have flanges on both sides of the web, giving them structural rigidity in the wall plane. U sections (tracks) are the horizontal top and bottom runners that the C studs slot into — they are open (no return lips) to allow the stud to be inserted and adjusted before fixing. The web width of C and U sections must match for the stud to fit correctly in the track.
What thickness is used for standard partition walls?
For standard non-load-bearing interior partition walls, 0.5–0.6 mm thickness is common in residential applications. Commercial and high-traffic partitions typically use 0.7–1.0 mm. Acoustic or fire-rated walls may require 1.2–2.0 mm studs at closer centres. The correct specification depends on wall height, acoustic rating, and fire resistance class required.
What galvanizing coating is standard?
LGS profiles are most commonly produced from Z140 galvanized coil (140 g/m² zinc, per EN 10346) for interior non-exposed applications. Z275 coating (275 g/m²) is specified for higher-humidity environments such as bathroom enclosures, external wall substrates, or humid climates. Please specify the required coating class in your inquiry.
Can LGS profiles be used for load-bearing walls?
Yes, with appropriate section design. Standard light gauge C sections in thicknesses from 1.0–2.0 mm can be designed as load-bearing studs for low-to-medium-rise construction when calculated to EN 1993-1-3. Structural LGS wall panels are widely used in prefabricated building systems. Please provide your load and height requirements for a structural grade recommendation.
