Railings & Brackets

Request for Quote

Roll Formed Railings are made up of Open Seam: Square, Round, Rectangular and Special Shaped Tubing, Flanged Seam Tubing. Framing, C-Channels, Box Channels, and Strut-Channels also make good Railings. Railings can also be plain U-Channels with Legs equal to, and taller than the dimension of the Web. Legs shorter than the web dimension can be used, however the shorter the legs get, the weaker the Railings become. Even Angles can be used as Railings. Open Seam Rectangular Tubing, Strut Channels, and Framing, with the opening on the short side, can offer a lot of extra strength and are common Railing styles. This is due to extra work hardening and formed surfaces. Round Open Seam and Flanged Seam Tubing are also common styles and perhaps the most economical. This is because Round, Semi-Round, Hex and other Special Shaped Tubing offer the best opportunity for forming with a Prefinish such as a Prepolished finish (that can be Prelaquered if necessary) with a Strippable-PVC covering, and many other Prefinishes. Other Unusually Shaped Open Seam Tubing can be designed and produced to match unusual architectural, insert, or bracket needs. Railings should not be confused with Rails, as Railings are specifically used for safety barriers and grab bars for stairs, walkways, mezzanines, lofts, guards, crowd movement and traffic control, hallways and other barrier uses. They can help protect, support and guide people or protect fixed objects and structures from moving things. Rails are used for much more than this. Railings, by necessity, are required to be strong, so thicker materials are used up to .125" thick and rarely below .048" thick. Roll Formed Railings offer advantages over other Railing styles through inline fabricating of: Holes, Slots, Notching, Perforating, Embossing, Shear Forms, Tabs, Cutouts, K/O's, End Fabricating and Cut-to-Length. Radius bends can also be done inline if the radius is large enough and the ends are not straight. Prefinished Materials are difficult to use on thicker materials. The thinner a Railing can be, the easier it is to use an inexpensive Prefinish. Some companies will use a Prefinished thinner wall Cladding to slide over the stronger Railing beneath, which can be made from a less expensive, thicker base metal, that is unfinished. Prefinishes used on thinner Railings, and Cladding to go over Railings, are: Prepolished, Preplated, Prelaquered, Strippable-PVC coating, Preanodized, Prelaminated Vinyl and Prepainted. It is rare that an .060" thickness can have these Prefinishes on simpler round Railings. Thicker than .060" is close to impossible. For thicker parts that cannot have these prefinishes, Post Finishing at extra expense, can be supplied, but Prefinished Cladding can be much less expensive. Thicker Railings up to .125" thickness can be produced with some Prefinishes that are not as decorative, but are less expensive, such as: Galvanized-(G30, G60, G90, G210, Electro, Bonderized, and Smooth-Brite), Aluminized, Galvanneal, Galvalume but the closer to .125" thickness, the more surface imperfections can appear during forming. These less expensive, and less decorative, Prefinishes can be a good economical choice for thinner Railings as well. Materials used for Roll Formed Railings are: Steel, Stainless, Brass, Bronze, Alloys, Copper, High Strength, Clad and Aluminum. Lengths can be as short 12" or as long as 40 feet. U-Channel & Angle Railings generally have Existing Tooling. There are many sizes of Open Seam Tubing that are also already tooled. Tooling on other shapes can be donated on high volume blanket orders but new die costs are often required. Some Existing Tooling is shown on our print examples link, and Tube size range chart. These are by no means a complete list of Railings we can produce.

Roll Formed Brackets: are generally not made for our railings but for uses in all industries as metal: Supports, Hangers, Reinforcements, Tracks, Slides, Connectors, Tube Joint Splicing and Bushings, and many other uses. Sections that are used as brackets are: Channels, Slats, Battens, Open Seam, Flanged Seam, Finned Seam & Lock Seam Tubing, Framing, Angles, Profiles, Special Shapes, Rails, Tracks, Slides, Zees, Louvers, Panels and others. Many Sections are the same as those used as Railings. Some customers also prefer to call certain Clamp Ring styles as Brackets. Please see our Rings & Clamps Section if that is your interest. Inline Fabricating is very common on Brackets, especially End Fabricating, Holes, Slots, Etc. Inline fabricating, Metals used, Thickness and Length capability, and Prefinishes used are the same as with Railings above. Tooling is Existing for many sections such as Channels, Angles, Open Seam and Lock Seam Tubing, and many other shapes. Other shapes can have new tooling designed and built for them.
