Agree the actual substrate and mechanical acceptance before ordering this galvanized building material.

Grade and strength

The record lists several steel designations without a numeric strength tied to a selected grade. State the required base material and mechanical tests rather than treating high-strength wording as a verified property.

Thickness and width

A 0.21–0.5 mm request appears with another 0.14–0.8 mm description. Confirm actual thickness, usable width and custom supply requirements instead of assuming every width range represents a stocked size.

• Actual substrate designation
• Mechanical test requirements
• Confirmed thickness and width
• Coating code and surface condition
• Cutting or forming acceptance

Coating evidence

Cold rolled base, hot dipping and a zinc code are described. Agree coating measurement and any additional precoat system; no BIS, JIS, GS or EN certification, outdoor lifetime or finished building performance is established.
