Aluminum Spiral Flex versus Steel Spiral Flex
Trying to understand the difference between aluminum spiral flex and steel spiral flex.
Is 3/8 inch aluminum flex suitable for stud notching applications?
Is 3/8 inch steel flex suitable for stud notching applications?
Is there a price difference? When would one be used versus the other?
I am pretty sure aluminum flex was used in my kitchen. The studs were notched and the flex was put in, held in place with a bracket.
How can I tell if it is aluminum or steel and does it even matter???
