Sectional garage door cables
Hi,
Yesterday one of the springs broke due to rusting at the bottom loop. Managed to replace it but came to think about using a stainless steel cable instead of galvanized one. Is there any reason we can't use stainless steel cable? Any one knows? Garage door expert out there? |

Can you buy SS cables for a GD? |

Also, stainless steel is much harder than ordinary steel, and so it's much more expensive to fabricate it. This is the primary reason why kitchen sinks will either be made of a relatively soft stainless steel or come with a price tag that gives you sticker shock. Stamping a piece of sheet metal into as radical a shape as a kitchen sink requires that you either use a soft metal or that you do everything you can to prevent the metal from cracking during the stamping process, and that means heating the steel to soften it, and stamping it with a layer of lubricant above and below the metal to minimize friction. If you want a kitchen sink made of a HARD and THICK stainless steel, prepare to pay 500+ dollars for it. Last edited by nestork : April 19th 14 at 04:28 AM |

Usually they are 1/8". eBay shows 1/8" stainless cables with 350 load limit which is more than enough. I could not find ready made stainless cables vs. gal. ones. So I was wondering about it. |

Garage door expert out there? I expect the reason for using ordinary galvanized steel cables is that in MOST instances, those cables don't rust out. They don't want to install stainless steel cables on every garage door they make if it's rare to see one rust out. It's more economic for the customer that finds his cables rusting to replace them with stainless steel cables than it is for the company to use stainless steel cables on every door they make when only a small percentage of the galvanized cables will ever need to be replaced.

Any how I ordered 20' of 7/16 strand of SS cable at 0.99 per foot, little more than twice the price of galv. steel cable. Next time spring or cable breaks, I am ready. Replacing pair of springs/cables took almost a day for a newbie but finished without any problems. Good thing, today(Good Friday) it is snowing again. |

I did have an extension spring go a few years ago. The doors didn't have safety cables, so I upgraded that to avoid getting hit in the head one day. If regular cables are an issue, it's likely only on some doors. Any obvious issues with OP's door that's causing the rusting? |

Page middle: http://www.mechanicsupport.com/galvanize.html Hi, I suspect it goes way beck when original wood sectional door was installled when house was built. Tha light wood panel door did not seal or provide good insulation. After 20 years cable snaped. Now door is steel craft foam core insulated and weather stripping is reinfoprced when door got replaced. Rust or not 20 years is good time for the cable to last. I swapped out both bottom brackets as well today for PM to have peace of mind. Having enough tools make the job little easier 3 vice grip pliers, winding bars I made,etc. |
