    Stainless steel or brass for Anchors

    Hi all

    I have read that with SWG a brass anchors is better than Stainless steel, galvanised or other materials which will not corrode easily. Is that true.

    What are the anchors for? Brass is a great choice and will basically not corrode. Brass is a bit softer than SS, however, so it's kind of a trade off.

    If there is not a lot of force involved (are you talking about anchors for ladders?) then I think brass is your best choice.

    FYI Almost all the pool parts that that we think of as made from brass are actually bronze. Bronze is preferred for salt water and acidic environments. There are salt water resistant brasses however most brass plumbing and hardware parts are made of standard free machining brass. On the other hand the metal used for pool junction boxes, some light niches, pump bodies and ladder clinches is bronze.

    Since the salt water in a pool is many times less corrosive than seawater and since the anchors will not be constantly immersed the distinction between brass and bronze may not be anything to worry about, but thought you'd like to know there is a difference.
