Hello everyone just joined the forum. Started out as a green sheet metal helper 8 years ago and now I pretty much do all aspects of commercial installation. I work for a company that has been established for nearly 50 years and used to be the biggest and best but I'm not too sure about that part nowadays. I have a major dilemma at the moment but I will post that question elsewhere. Anyway I hope to learn some valuable information here and to be able to contribute help from the things I've learned.
