Bulk road salt store

[Hilti]

Currently tipped out side on concrete pad & soon turns to turd .

looking to alter a bay of existing shed to store 100 - 120 t of road salt .
Any tips on getting it sealed up so salt doesn't eat everything.
block wall between stanchions 1 side , other sides be done with panels & pour floor . Will the z purlins be ok ?

thanks

Panels would be ok if they are mastic sealed perfectly, but if they aren’t then the steel work could be corroding without you knowing about it. If it was mine I would pour an RC wall to the heap height and rise the the roof structure of that.

definitely not z purlins, use timber
