"Hot dipped galvanized vs. electrogalvanized"
2006
Clevis hangers that are to be used to back up piping are available in hot dipped galvanized terminate or Electro- Galvanized. My question is which blanket is the better?

Hi, Graeme. Electrogalvanized but ways zinc electroplated. Either electroplating or hot dipping tin can be used to use the coating of zinc to steel (and there are other methods besides). Zinc electroplating has a definite reward in appearance and for close fitting parts, simply hot dipping will requite much better corrosion resistance because the zinc coating will be about five times thicker.
Very similar questions take been asked and answered many times on this site. So if you need a 2nd opinion, patient application of the search engine volition yield information technology.

I am planning a fence that will incorporate stringer hangers that are either hot dipped galvanized or electro galvanized. Can I apply hot dipped galvanized nails with electro galvanized hangers and visa versa?

Hi, Daniel. "Electro galvanized" means zinc electroplated. I don't know the origin of the term but it may have merely been an invention by a marketing director to endeavor to ride the coattails of the more expensive and more durable finish through obfuscation :-)
There should be no compatibility problem between the two finishes just the electroplated parts may not evidence very durable in outdoor exposure as the protective zinc coating will merely be mayhap a fifth as thick equally the hot dipped coating. In that location is zip intrinsically questionable well-nigh electroplating; it tin can be an outstanding finish. But zinc electroplating is no substitute for galvanizing in outdoor exposure. Good luck.

I am re-roofing my house. The local code calls for 8D ring-shanked roofing nails to re-nail the plywood decking which, in my case, is 1/two inch plywood. The re-roof will be premium material: 30 # standard felt but and then 170 # with 250 # in the valleys and at penetrations. Accordingly, I spec'ed premium nails even though roof will be hot-mopped with premium 170 modified SBS underlayment/250 as in a higher place then tile roof. I wanted Maze of Peru, Illinois, double-hot dipped galvanized 8D nails (Maze production # R107A)but it turns out that Maze smash must be manus-driven and my roofer uses an Hitachi 75 AG nail coil gun. He is proposing to apply Hitachi ring-shanked diamond point "electro-galvanized" nails---made in the United Arab Emirates. Is this excellent or is there a meliorate product out there for my application which can be used with a coil gun? Or is this UAE-manufactured nail a pretty good product? (I recognize information technology is not as corrosion-resistant as double hot-dipped and CORROSION is my prime number quality issue for the nails). Shall I just go with the flow or can I become something REALLY good which works in a gun? The paw-driving volition add together about two man days at $ 55/hour to my price (almost $k) I am told. What should I do?
Thank you VERY MUCH!

Hi, James. As long every bit this plywood is not pressure treated (and it shouldn't exist), and every bit long equally the nails are not exposed, I would retrieve that you can allow the architect use the nails that he must apply for ability tools (hot dip galvanized coatings are probably too thick and drippy to use in these machines). But where y'all take exposed nails, like the top grade of shingles at the acme of the roof, you could inquire him to manus drive hot dip galvanized nails.

Ted,
Great insight on these questions. My visitor works as a manufacturer of custom roofing materials. We have sources for hot-dip galvanizing and electro-galvanizing. Our electro-galvanizer has two types he refers to as yellow zinc and white zinc. The products nosotros industry are of course used for outdoor applications. Can you provide some insight into the dissimilar types of zinc and if one coating is preferred in an outdoor setting.
Thanks

Hello, Jacob. Zinc plated materials are invariably chromate conversion coated to deter white rust. Traditionally these chromates were hexavalent chrome based, and hexavalent chrome is yellow-bister in color. Hence the name "yellow zinc". The color could exist leached out in hot water, or the blanket applied very thin, or trivalent chromate used instead then that it was more than clear or more like "white zinc".
Yellow zinc traditionally had much more hexavalent chrome and offered ameliorate corrosion resistance. Merely today there is pregnant environmental pressure to cease using hexavalent chromates, and in many industries (like the automobile industry) only trivalent chromates are used anymore. Some say today'due south trivalent chromates are the equal of yesteryear'southward hexavalent chromates.
n the auto industry today the trivalent chromates are simply dyed yellow and are otherwise exactly equal to the "white". Pitiful, I don't know whether your yellowish roofing textile is hexavalent chromated or trivalent chromated and dyed, but that's the short term reply anyway. Eventually there will be no more than hexavalent chromium in roofing textile and in that location will exist no functioning difference between yellow and white. Good luck.

Q. I am looking to purchase Galvanized Zinc coated Hexagonal mesh wire (Craven wire) to make fish traps for fishing in the sea/sea.
I would like to know the life expectancy of electro galvanized steel wire versus hot dipped galvanized steel wire versus PVC coated.
I know that hot dipped last longer equally it is thicker only I only need something that will last five-8 months when immersed in salt water and that will not be too expensive.
All-time regards.

A. Hi. PVC volition final "forever" until it is cutting, but information technology will be, then it won't last long. I think electrogalvanizing will be completely worthless in the ocean. Deplorable but your suppliers or even local fishermen will know more near the real world durability than I would.
