Quick assembly: Lightweight components are easy to cut on-site, and the screw-fastened or clip-on connections eliminate wet trades, shortening schedules.

Dimensional stability: Galvanized coating resists moisture warping, keeping ceilings and partition lines true over time.  

Service integration: Open-web sections allow ducts, conduit and piping to pass through without extra notching, saving headroom.  

Fire & acoustic upgrades: When paired with mineral wool and multiple layers of fire-rated board, 60–120 min fire resistance and 45–55 dB sound reduction are readily achieved.  

Typical Section Properties (common U-C profiles)

Finishing Compatibility  

Gypsum plasterboard, fibre-cement board, calcium-silicate board, magnesium-oxide board, plywood, MDF, decorative metal panels, stretch-fabric membranes.  

Corrosion & Coating Options  

• Standard: Z120–Z275 g/m² hot-dip zinc (G40–G90).  

• Enhanced: Zn-Al-Mg alloy coating (150–200 g/m²) for coastal or high-humidity zones.  

• Optional colour-coated polyester or PVDF top coat for exposed grid applications.  

Sustainability Credentials  

• 100 % recyclable steel; typical recycled content 25–30 %.  

• Factory roll-forming generates <2 % scrap, all of which is re-melted.  

• Light weight reduces transport energy and structural load, allowing smaller concrete/steel primary frames.  

Design Codes & Testing  

• EN 14195:2005 (EU), ASTM C645 & C754 (US), GB/T 11981-2020 (CN).  

• Load-span tables verified by third-party tests for 1/240 deflection limit at 1.5 × design load.  

• Seismic tested per ICC-ES AC 261, suitable for S_DS up to 2.0 g.  

Packing & Logistics  

• Bundled in 3 000 mm lengths (custom 2 400–6 000 mm), 10-piece shrink-wrapped packs, 50–60 bundles per pallet.  

• One 40 ft HC container loads ≈ 25 t (≈ 22 km of UC50 stud), enough for 4 000–5 000 m² of partition.  

Installation Tips  

1. Maintain 300–400 mm end-bearing on tracks; use acoustic isolating pads where partitions meet structural slabs.  

2. Stagger board joints on opposite sides by ≥ 600 mm; leave 3 mm perimeter gap filled with acoustic sealant.  

3. For heavy fixtures (basins, TVs), back-to-back double studs or timber noggins should be pre-installed before boarding.  

Future Trends  

• Prefabricated “cassettes” with factory-fixed boards and pre-routed service holes cut site labour by 30 %.  

• 3-D roll-forming machines now produce variable-depth studs (deeper at mid-span) to save 8–12 % steel weight.  

• BIM-embedded libraries allow direct export of cut lists and CNC roll-forming files, reducing detailing errors to near zero.
