Key Features
- Uniform zero / minimized spangle — this is the selection-defining characteristic of this listing, alongside the family option list below.
Key Features
- 55% Al-Zn alloy coating — enhanced corrosion resistance and heat reflectivity versus plain zinc coating, suited to exposed roofing and cladding.
- Grade range for different end uses — DX51D+AZ for general forming; S350GD+AZ and higher structural grades for load-bearing profiles, purlins and decking.
- Flexible coating mass — AZ80 to AZ150 to match the service environment and expected lifespan.
- Clear surface specification — spangle (zero / minimized / regular) and surface treatment (oiled / dry / chromated / non-chromated / anti-fingerprint) specified separately.
- Slitting & cut-to-length — supplied to your exact width and length, reducing additional handling before roll forming.
- Traceable material — mill test certificates and batch identification available according to order requirements.
Applications
- Primary: Uniform-clad appearance and paint base.
Applications
- Metal roofing sheet and corrugated roofing production
- Wall cladding and liner panels
- Roll-formed building and structural profiles
- C and Z purlins using suitable structural grades (S350GD+AZ / S550GD+AZ)
- Decking and floor deck profiles
- Photovoltaic mounting and support components
