soppalco beam reinforcement

[odisseo 18]

hi, I made a mezzanine using 80x40 x 2 mm canned iron beams, I realized that the flow is as modest as I could do x spray them and increase the flow rate, loft size 2,70x 3,60 m inter axis beams 90 cm the beams are rested on perforated masonry

to avoid this inconvenience, I wanted to approach a 80x50 mm inequal, but it was too exaggerated, therefore I used the other system, I put on it a beam to u type hat, I thought to have in part remedied to the error, from empirical calculations I found that a beam from 80x40x 2 mm in galvanized it had a load of 190 kg in half-work, with this system design critical appearance thanks
