Salt or Calcium Chloride
Salt or Calcium Chloride
(OP)
Structural here needs some help
We have many catwalks, scaffolding, walk ways made from painted steel and/or galvanized steel.
The question has come up - Is it better to de-ice these with salt (don't think so) or calcium chloride?
Or is there a better chemical we should be using??
Hair dryers are not accpetable!!
Thanks

The most common salt is calcium chloride because it is has the least problems with freezing. You can also apply it as a liquid. Magnesium chloride is generally applied as liquid.
You will have corrosion problems with all of the salt chemicals. The following link has some information for structural designers:

1. Use of sand is limited, and without proper sieving - you will ensure that some of the road users will be blessing you for the sand blasting and bigger stones hit effects.
2. Application of the chloride-based salts is effcient, and each can be used in liquid form, to avoid above problem.
3. Application of all of the chloride-based salts is related with the corrosion.
4. Before use, check the efficiency (i.e. in Europe there is common policy, that below 10-15C salts are not effective anymore and only one choice is a sand).
