What size I beam?

[Ken Fitzgerald]

Jaromir,

Contact the company from whom you plan on buying the I-beam. They can contact a structural engineer with the manufacturing company. He can suggest the proper I-beam.

When I needed to replace an existing header on my carport with a glue-lam, the lumberyard where I ordered it called the manufacturer. A structural engineer employed by the manufacturer asked me a few questions about the roof over it and span. He then made a recommendation.

[Peter Aeschliman]

Agreed. Definitely not the sort of thing you should trust to strangers on the internet.

[Jaromir Svoboda]

Thanks, good idea.
