Bulk feed Bin Suppliers

[welger rp 220]

I'm looking at purchasing a new 12 or 15 tonne feed bin..Who supplies these?
Is there much difference to the fibreglass ones to the steel ones as in storing the feed would it stick or go damp in a galv steel bin ?

Bildabin silos are decent fibreglass,but they lack enough viewing windows, depends on your ordering system,
The cone is unpainted and translucent ,but the main body is painted and gives no clue

Collinson bins have more viewing windows better for frequent deliveries
