screwing into aluminum channel

Can you screw into aluminum that is 1/8" thick? *I know you can screw into sheet metal, but I wonder if 1/8" thick aluminum would just strip screws. I found some aluminum channel online that is 1.5" deep and 1.5" wide, with 1/8" thick metal, online and I'm wondering if this would work as channel to attach drywall to. If these aluminum channels don't work, perhaps I could use PVC. *I found PVC "1x4" planks at Lowe's, and two of these would give me the 1.5" thickness, at about the same cost as the aluminum channel. *Or maybe there are PVC "2x2" strips available somewhere. *It's in a situation where I don't want to use wood. Laura They do make some PVC trim that measures 1 1/2" x 3/4". As long as you can aim your screws into the 3/4" face, that would give you the 1/5" spacing you want, or you could use Super Glue and make your own 2 x 2's Of course, PVC is pretty flexible so keeping it straight from floor to ceiling is going to be an issue. 2 questions: 1 - Where are you willing to use drywall but not wooden studs? 2 - Is the 1 1/2" a firm requirement? PVC trim comes in all sorts of sizes that might work if you have some leeway. |

Yes, the 1.5" thickness is a rigid requirement. *+- no more than about 1/8". So to recap: *I'm thinking of using some aluminum channel, 1.5" deep, 1.5" wide, 1/8" thick metal, to mount drywall on a concrete block wall. Could I screw into aluminum with deck screws? *I would make pilot holes. Apparently aluminum may corrode if it's in contact with stainless steel. *Someone suggested deck screws because they're painted, so perhaps there wouldn't be aluminum/other metal contact. *I read online about a solution that you would paint the aluminum with before screwing into it. For the wall the best thing so far seems to be DensArmor Plus, a kind of drywall with fiberglass facing rather than paper. Laura I use SS clamps wit aluminum tubing out doors and have had no problem. Some of this has been exposed to the wx for 10 years or more. Jimmie |

Laura I know it's none of our business, but since you asked for our help, I feel we have the right to ask (again)... Why are you not willing to use wood as your studs? In addition...a new question that I don't think has been asked befo How are you planning on supporting the aluminum channel, or whatever stud material you choose? Will it be attached to the floor and ceiling joists or attached to the block itself? You seem to be concerned about the types of screws to use for the drywall, but what about the anchoring screws for your framing? "Could I screw into aluminum with deck screws? I would make pilot holes." 1 - How will you find the pilot holes after you stand the drywall up against the channel? 2 - I've never tried deck screws in 1/8" aluminum, with or without pilot holes. Obviously the pilot holes would have to be small enough so that the screws bit into the channel. I'm not sure how well that would work...certainly worth a few test runs. You'd have to ensure that you used screws that had threads high enough up the shaft so that the threads were still biting into the aluminum when tight. |

Laura Why, oh why won't you respond to the numerous inquires as to why you don't want to use wood? At least 3 different peple have asked, you've responded to other parts of their posts (including mine) but you never address the "Why not wood?" question. Why is that? |

Why is that?- Hide quoted text - - Show quoted text - The other thing to consider is how many basements with cement block walls are finished everyday with drywall without having to come up with novel mounting methods. I'd do some googling on the subject and I think the results will be that wood is typically used without problems. An alternate way of looking at it is if it's so wet that wood can't be used, then I think he's got bigger problems than the fastening method. |

Two dissimilar metals + moisture = galvanic corrosion. Or maybe I could use galvanized steel channels? *I'm not sure if those are available in the right size. Use steel studs. They're far better suited than aluminum. Or use pressure-treated lumber. It's made for this kind of thing. To attach drywall to the channels, I need to use screws with a flat head, like deck screws or drywall screws. *The metal screws I saw didn't have flat heads. If anything 1/8" aluminum is TOO THICK if you want to drive drywall screws into it. Even with pilot holes, the screws will either strip out or jam and snap off. |

Because, our friend "Laura" here has it in her head that what she is trying to do has never been done before, and that the only way to do it is the most unconventional, expensive, complicated, asinine, and cockamaime way known to man. She will make eleventy-dozen excuses why normal, accepted methods and materials won't work because hers is a "special" situation. For certain, it's a wet basement. Oh, but she can't fix the water intrusion problem properly for eleventy-dozen reasons, but she's got magic paint that's just as good. Oh and she absolutely HAS to have a finished basement... Normal corner-cutters would simply fir out the wall with pressure- treated lumber. Oh, but not our friend Laura. She's got some "thing" about the chemicals they use in pressure-treated lumber. It's all for the children. Doesn't matter that the mold and mildew that's growing behind the drywall is going to kill her kids long before the trace amounts of arsenic will. There's arsenic in her bottled water and arsenic in the kids juice drinks, but that's okay. The boards buried behind the drywall are DEADLY! We can't use steel studs because of the moisture. Steel rusts, right? Hmm, what can our friend Laura use... Wait, aluminum isn't steel, and if it's not steel it doesn't rust right? Aluminum is the answer! WRONG: Alumium studs + steel screws + moisture = battery There won't be anything left under the drywall in 6 months, except mold and mildew. |
