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.
