Define actual scaffold tube dimensions and design requirements before accepting galvanized pipe.
OD and material
The title requests 48.3 and 60.3 mm with Q235B or Q355B, while the detailed material and diameter fields have different scope. Confirm actual designation and OD with evidence rather than assuming every titled size is supplied.
Wall and route
The actual thickness choice spans 0.5–27 mm with a12 m length. Agree a physically compatible wall and verify the requested ERW construction and end condition for the intended scaffold system.
- Actual steel designation
- Measured OD and wall
- ERW manufacturing evidence
- Supply length and end details
- Zinc and scaffold inspection
Design acceptance
The zinc layer is written as 0.8–4.0 mm. Clarify its intended meaning and units; certificate and scaffolding wording does not establish load capacity, connection compatibility, corrosion lifetime or approval of an assembled scaffold.
