  U&Z&C channel

Use a section drawing and actual material designation to specify channel for a framing project.

Grade and profile

The record names Q235B, Q345B and A36 while also listing U, Z and C forms. Agree one actual grade and profile instead of treating these designations or shapes as interchangeable structural members.

Section dimensions

The actual dimension options are 5#, 8# and custom entries, with broader thickness and length descriptions. Confirm the corresponding section geometry, wall dimensions and usable length; a number sign alone does not provide a complete section drawing.

• Actual material designation
• U, Z or C drawing
• Section dimensions and tolerance
• Finished length and surface
• Framing design acceptance

Fabrication condition

The detail states a black surface and a nonperforated condition despite broader material references. Agree the actual delivery and any fabrication requirements; purlin or framing wording does not establish load capacity or compatibility with a particular building system.
