Provide a section and hole drawing when requesting galvanized C channel for a roof system.

Actual section

The record names several carbon steel grades and describes cold bending. Select one actual designation and C profile, then clarify the units and geometry of the listed dimension range instead of deriving a complete section from model numbers.

Perforation layout

This item is described as perforated, but hole dimensions and spacing are not supplied. Agree the hole arrangement, edge distances and finished length with the connection design before choosing the delivered channel.

• Actual steel designation
• C section drawing and units
• Hole size and spacing
• Finished length and tolerance
• Zinc and roof system inspection

Assembly acceptance

The title requests galvanizing without a confirmed coating basis in the dimensions. Agree actual zinc inspection and installation criteria; purlin wording does not establish a roof load rating, connection compatibility or certification of an assembled building system.
