How do your bins compare with Westeel regarding gauge and features?

Gauge to gauge, with the exception of a few models are bins are heavier as we have updated our current designs giving them more steel where required so they can handle higher stress loads. Darmani does offer many value-added features. Click a link below for more details.

If I extend my bins, what do I do with existing stiffeners?

You can either add more Westeel type angle iron stiffeners or it is recommended to go to a heavier Darmani style stiffener and mount on outside making it both stronger and easier to clean out with no hang-ups.

Can I add a tier to my bins and then put them onto these DARMANI cones?

Yes, but that will be determined by the size and style of bin you are starting with. DARMANI manufactures the bin sheets and stiffeners required to extend your bins so that they are stronger than originally manufactured.

Do you I have to replace door with door filler sheets?

Yes, as the doors are meant for Flat bottom bins and the stress loads on Hopper bins increases and so it would be necessary to prevent any future damage that could occur.
