Beam online calculations
From your descrlption, it does not seem that your beams are standard S or W type beams, as those numbers do not match any of the standard beam specs.
When it comes to beam bending, the single most important factor is the area moment of inertia of the cross section area of the beam (I) about the neutral axis. If possible at all, please email us (firstname.lastname@example.org) the drawings of your beams' geometry and we'll take a look. Even a simple scanned hand sketch helps a lot.
