Define the actual substrate and coating before selecting coil for cutting or forming.

Thickness and width

The title requests 0.21–0.5 mm, while the description also gives a broader 0.14–0.8 mm range. Agree actual thickness and one usable width within the four selectable range labels.

Coating and base grade

The record identifies galvanized coil and a Z30–Z40 code, without a coating measurement basis. Choose the actual base steel designation and clarify whether any additional precoat system is required.

• Actual base steel grade
• Confirmed thickness and width
• Coil or cut sheet delivery
• Zinc designation and test basis
• Surface and forming acceptance

Building requirements

Skin pass, non-oiled and hot dipped processing are described. Agree surface and cutting requirements; BIS, JIS, GS and EN references do not establish certification, outdoor durability or performance of a completed building system.
