  Third Party Inspection

Agree actual delivered surface before selecting carbon coil for downstream fabrication.

Black or galvanized

The title combines black carbon coil and hot dip galvanizing while the detail provides a zinc mass range. Select actual coating and base designation rather than describing black and galvanized conditions as one verified supplied surface.

Grade and size

The grade field names Q235 and Q355 while the material list uses other carbon references. Confirm actual designation, thickness, usable width and supplied length with dimensional tolerance and skin pass requirements for the intended process.

• Actual carbon designation
• Selected thickness and width
• Supplied length and tolerance
• Black or zinc surface inspection
• Fabrication material tests

Inspection evidence

Third party inspection is named without an attached result. Request actual reports; factory and high strength wording establishes no manufacturer identity, certified strength, coating lifetime or structural load capacity.
