Supplied in small bags, Hallstone De-icing Salt is Brown Rock Salt, which does not have any grit or sand added, meaning it will naturally disperse over time unlike some salt substitutes; it contains only a very small amount of anti-caking agent to allow prolonged storage (less than 30mg perkg approx.) Our De-icing Salt complies with British Standard BS3247:2011 & is Approx. 6mm in size, which is ideal to be used in spreaders. If 20 bags is slightly more than you require, why not split the cost & pallet with your neighbours?
