Confirm the actual pipe material before using broad galvanized grade references in an order.
Grade scope
The title lists several coated-steel designations while the detailed material list names carbon pipe references. Select one actual pipe designation and applicable standard instead of treating the full title list as interchangeable certified pipe grades.
Geometry and zinc
The actual wall option and detailed wall range differ, and the OD fields give separate scopes. Agree compatible measured OD, wall and 6 or 12 m length, then clarify the zinc layer field written in millimeters without silently changing its meaning.
- Actual pipe designation
- Outside diameter and wall
- Finished length and tolerance
- Zinc layer measurement basis
- Non-oiled surface inspection
Application acceptance
Fluid, boiler and structural labels provide no engineering rating. Request actual material and design records; the listing establishes no pressure capability, certified grade compliance or guaranteed corrosion lifetime.
