Specify the gauge convention and actual roofing profile before selecting galvanized zinc sheet.

Gauge and base

The title requests 18, 20 and 22 gauge while the detail states a millimeter thickness range. Confirm actual gauge system, measured thickness and one supplied steel designation rather than assuming a direct conversion or all-grade stock.

Wave and paint

The record describes wave tile and several color or coating alternatives. Agree profile drawing, effective cover width, finished length and actual paint system, clarifying the Z30–Z40 coating code and any copper-coated wording for the order.

• Gauge system and thickness
• Actual substrate designation
• Wave drawing and cover width
• Color and coating inspection
• Cut length and fixing criteria

Roofing acceptance

Actual width and length choices are ranges. Request delivered material and installation tests; roofing and wear-resistant labels establish no roof load rating, waterproof system approval or weathering lifetime.
