Define the actual substrate and corrugated profile before selecting a painted roofing sheet.

Coating system

The title combines galvanized and galvalume, while the detail lists several surface treatments and paint chemistries. Agree zinc versus aluminium-zinc substrate and one actual PE, SMP, HDP or PVDF system rather than treating them as interchangeable coatings.

Profile and dimensions

The actual width and length choices are ranges. Confirm whether width is overall or effective coverage, then specify corrugation geometry, thickness and a finished cut length.

• Actual substrate and base grade
• Profile drawing and coverage
• Thickness and cut dimensions
• Paint and back coating scope
• Colour sample and inspection

Roof requirements

A back coating range is described without a complete paint specification. Agree measurement and installation acceptance; no wind rating, water tightness, weathering life or roof system approval is established by the broad application description.
