Profile pages

The profiles in this family each have a page with sizes, kg/m and fixing guides: omega / hat profiles for cladding sub-frames, roof battens and solar rails, and M profiles / furring channels for ceilings and wall lining. Structural roof members are the C purlins and Z purlins.

Material and coating

DX51D+Z140 for non-structural battens and ceilings; S280GD / S350GD+Z275 for load-bearing studs, purlins and sigma sections (EN 1993-1-3 design uses the guaranteed yield); ZM250–ZM310 for solar rails, coastal cladding sub-frames and 25-year warranties; pre-painted +Z for visible battens. Thickness tolerance per EN 10143, profile per EN 10162.

Custom profiles

Beyond the standard sections we build tooling for customer profiles — special hats, cladding rails with clip slots, solar rails, shelving uprights, door frames, trailer and container parts — from 5 t per section; tooling cost is quoted separately or amortised. Lead time for new tooling 3–5 weeks, then 7–12 working days per run. See also oval and custom profiles.

Applications

  • Ventilated façade sub-frames (omega, L, M) behind ACM, fibre-cement, stone and metal cladding
  • Roof battens for tile, standing-seam and sandwich-panel systems
  • Light-gauge steel houses, villas, site camps, extensions (C/U framing kits)
  • Drywall partitions and suspended ceilings (EN 14195 studs, tracks, furring)
  • Solar-panel mounting rails (omega / hat in ZM)
  • Mezzanine floors and purlins (sigma, C 250–300)

Price per ton and per metre

Priced per ton from the galvanized strip band plus roll-forming, punching and cutting, or per metre for standard sections; thin (0.5–0.8 mm) and small profiles cost more per ton than heavy ones. As a guide, standard omega and LGS sections sit 15–25% above the pre-galvanized hollow-section band. Firm price per section list within one working day.

Frequently asked questions

What is an omega profile used for?

As a batten or rail: it fixes cladding, roofing and solar panels to the structure while leaving a ventilated gap; the two feet screw to the support and the hat carries the cladding. 40×40×1.0 Z275 is the most ordered size.

What is light-gauge steel framing?

Structural framing from cold-formed galvanized C studs and U tracks (0.75–2.0 mm, S350GD) assembled into wall panels, floor joists and roof trusses — for houses, villas, camps, extensions and mezzanines. Designed to EN 1993-1-3 or AISI S100.

Can you supply LGS profiles punched for framing machines?

Yes — service holes, dimples, notches and flange holes to the machine's or the engineer's pattern; or plain profiles for site assembly.

What thickness for load-bearing studs?

1.0–1.5 mm S350GD for one- and two-storey walls (C89/C100), 1.5–2.0 mm for floor joists (C150–C200); non-load-bearing partitions 0.5–0.75 mm.

Do you make custom profiles?

Yes — tooling for your section from 5 t per run, 3–5 weeks for tooling, then 7–12 working days per order.

How are prices quoted?

Per ton or per metre from the galvanized strip band plus forming and punching; thin small profiles are dearer per ton. Firm price per section list within one working day.
