elevated pipe support

[Structures33]

Hey there - I need to provide a detail for supporting 4 steel pipes laying side by side. The support will be 7' high and outside. I am not familiar with pipe support products beyond stanchion saddle-type supports. The client has provided a sketch of what they envision - a single steel pipe column supporing a platform at the top. What is typically used for the platform supporting the pipes?
Thanks

These are typically called "pipe racks". And I believe there are some codes for them. Search these forms - I have seen it discussed a few times.

Any wide flange shape that meets the deflection and stress requirements, (50 psf minimum for supported area, span times the width of support beam).
