Yes, most of them do advertise in the magazines or on this site.
MK Metals did, and it was customers who found them wanting. You can also find others by diligent Internet-hunting.

It is becoming harder for companies to sell to individuals what is normally only bought by industry, but I’d not have thought metals would come under legislation like product safety. Yet many building-trade suppliers sell to the public, sizeable quantities of lime and cement (corrosive), timber-preservatives (potential harm to the skin), fibre-glass insulation (irritant), heavy materials (manual-handling hazard), power-tools (all sorts of dangers), edge-tools (sharp!)…
Regarding servicing, are there smaller, independent companies who can do this?
I suspect the most likely reason for refusal is still simply not wanting small, ad-hoc purchases, as a full trade account brings bigger and regular cash-flow (provided the customers pay) and proportionately far less administration. In that regard though, the private buyer is safer for the seller as the transaction is normally c.w.o.
Though these days there are characters about who seem to be paid to declare anything “hazardous”. My local paper today carries a curious tale of the emergency services removing “a hazardous material” from a flat, without saying what it was! Nor how they knew it was there – but as this was a flat perhaps a nervous new occupier found it.
