Agree the actual outside section and wall before requesting galvanized hollow tube.

Side dimensions

The detail identifies square ERW tube while the title also names rectangular pipe and 2.5 inch. Confirm shape and dimension convention with actual sides rather than treating the title as a verified outside size or a complete rectangle drawing.

Wall and length

The actual wall range differs from the detailed wall scope, and length options include 6, 6.4 and 12 m. Select a compatible wall and finished length for the requested section with dimensional acceptance and non-oiled surface criteria.

• Actual steel designation
• Outside side drawing and units
• Compatible wall and tolerance
• Finished length and surface
• Zinc layer inspection

Application evidence

The zinc layer range needs actual order measurement. Request material and project records; fluid and construction wording establishes no pressure capability, structural capacity or certified ASTM compliance.
