Coltwell Industries

With a large variety of presses available for production Coltwell offers aluminum extrusions in a variety of alloys. Most alloys are available in both hollow and solid shapes:

Welded Tubing provides aluminum tube customers with an alternative to drawn and extruded tube. Welded tube is on average 15% stronger than extrusions and can offer equal and sometimes greater strength at lower gauges. Welded tubing is utilized many applications such as outdoor furniture, healthcare equipment, household fixtures, and athletic accessories. Welded tube has also found its way into applications where steel tubing is traditionally used. Coltwell offers both round and square welded tubing in a variety of alloys and tempers within the 3000 and 5000 series, as well as a variety of sizes:

In addition to standard profiles, we also produce custom shapes that have been specifically designed by our customers for their own product. Enclosures, heat sinks, telescoping tubes, trim molding, lighting fixtures and odd shaped hollows and solids are examples of custom profiles manufactured by Coltwell for our customers. We produce profiles which range in size from mini up to large circle size. To find your circle size, determine the diameter of the smallest circle that will entirely enclose the cross-section of your part. This will be the profile's circle size. Our profiles are available in many hard and soft alloys such as 1000, 2000, 3000, 5000, 6000, 7000 series alloys in various tempers. Aluminum alloys are selected for their unique characteristics including strength, corrosive resistance, machining and versatility. In conjunction with our aluminum profiles, we offer as an additional service to our customers if their product requires it, injection molded plastic components to complement the product. This service provides our customers with the comfort of a finished product with sole source responsibility. Good multi-purpose alloys are found in the 6000 series. The 5000 series offers strong welding characteristics and corrosion resistance in a marine environment. Alloy series 2000 and 7000 are high in strength and widely used in the aircraft industry. The 1000 series is better than 99% pure aluminum and has several applications typically in the electrical and chemical fields. Our profiles are available in several types of finishes. In addition, secondary fabrication is also available to our customers. Prior to designing your profile you should consider the function of the product, the tolerances required, the surface finish and the alloy. Often times, a standard shape can be utilized rather than a custom shape by making slight modifications to your product.

For superior strength, hardness, thin walls, impeccable surface finish, consistent dimensional tolerances, and precise bending capability drawn tubing is the answer. Coltwell has the expertise, machinery and tooling required to make drawn tubes in all shapes and sizes. Coltwell’s superior drawn tube is used for tent poles, antennas, chairs, extension poles, air cylinders, and many other recreational, automotive, marine, and health-care applications. Drawn tubing is also ideal for telescoping tubing. It is ideal for applications that require tight tolerances, thin walls, high structural integrity and predictable performance under pressureMinimums as low as 500lbs Smallest OD at 316” Largest OD at 5.5” 0.028” thinnest wall thickness Shortest lead times in the industry Production in both Porthole Drawn (ASTM B483) and Seamless Drawn (ASTM B210) A variety of alloys including 1000 series, 3000 series, and 6000 series A variety of custom tube sizes can be produced In House Fabrication available (including Tube Bending) Variety of Finishes available (including Anodizing, Powder Coat, Polished and Brushed) A variety of blanket order warehouse and stocking
