Hollaender's® lines of modular pipe fittings - Speed-Rail® slip-on fittings and Interna-Rail® internal fittings - are the broadest line of aluminum pipe fittings available - ANYWHERE!

Hollaender® pipe fittings are made of high tensile strength, aluminum/magnesium alloy 535 with physical strength characteristics comparable to that of malleable iron at only one-third the weight. This alloy can be used with any other metal, including carbon or stainless steel, without fear of electrolytic (dissimilar metal) corrosion. We also carry major inventories of aluminum pipe in all IPS sizes, in both anodized and architectural mill finish, for use in any structural application required.
