Smallest beams

[onthehoof]

Want to put a retaining wall up using 4inch concrete panels and slot them into upright steel rsj’s but struggling to find any right size i.e. about 5inches wide does anyone make that size?

We made a whole crop bunker using 6" panels. Erector used 2 chanels welded back to back to slot the panels into. Will have to look up the size

Size - PFC 180mm x 75mm Nice snug fit

127x76 U beam has 7.6mm flange so about 111mm gap, but quite a light beam might be better with two channels back to back as above? 126x65 channel has 9.5mm flange so gap would be 107mm.

As the above. For 100mm panels the best way is to use channel welded to form a H shape column
