Like some others I ordered this back when the description was read to make you think it was copper now it says 'corrosion resistant' or something. But make no mistake, it's just scrap steel! The "cover" failed and it got rusty just when it was hanging in my bag on a nail in the garage. Thank god I never made it to the project I bought it for because I'd be really pissed if I did all the work to cut the torch and do all the assembly only to find out how quickly and easily it rusts. If he does it outside, he'll do it the same way inside, maybe even worse! I know we all want to save money, but come on, do you really care so little about your specific project that you'd waste your time on something like this? I will not. Lesson learned. This roll goes in the trash. You shouldn't be allowed to sell things like that.
