dimensions, but with a thinner web. As you have been advised here, you
should consult a structural engineer to determine the SWL that the beam is
required carry, & also the type of foundation that is needed to carry both
beam & load. There is no point in using a beam that can support 20 tons,
if the foundation that supports the beam & the load can only support 5
tons. Foundations have a bearing on loads.

.You do realize you need a structural engineer to give you calculations
for the beam to ensure it is strong enough for the purpose this is not
just a nice thing to have it is part of building regulations when removing
walls & replacing with steels.Also do you plan to add anything above the
beam in the future such as an extension etc.

Well it depends on what it`s holding up.

The difference is obvious.The one is bigger and will hold more weight.
