Specify the actual wave profile and thickness before selecting a roofing sheet size.

Gauge and profile

The title requests 18, 20 and 22 gauge, while the description gives a millimetre thickness range. Agree the applicable gauge convention and profile drawing instead of converting the gauge labels without evidence.

Width and length

The selectable width spans 665–1100 mm with four length ranges. Confirm whether width means overall sheet or effective coverage, and select one actual cut length with overlap requirements defined.

• Base steel and actual thickness
• Wave profile and coverage
• Cut length and overlap
• Zinc and colour coating system
• Roof design and inspection criteria

Coating acceptance

Galvanized, copper coated and colour coated wording appears as alternatives. Agree the supplied system and sample; no weathering life, wind load, waterproof installation performance or certification is established by the roofing description.
