One of the reasons that steel is so prominent in our society is its versatility. This section focuses on the ways that steel can be altered to fit the specific needs of your application. Here we cover some of the basics of welding, coating and storing galvanized steel tube products.

With an ever expanding range of uses, Allied Tube & Conduit®’s in-line galvanized tubing must be versatile. Our capabilities include shapes such as: round, square, rectangle and flat-sized ovals. These shapes come in a number of different wall thicknesses for use in the majority of mechanical and structural applications. Allied tube & Conduit’s tubing is manufactured to ASTM A500. Custom requirements are available to meet your specific needs.


We guarantee a minimum 50 ksi yield and 55 ksi tensile on many of our products with the ability to achieve even higher properties.  Compared to Schedule 40 pipe at 30 ksi, Allied Tube & Conduit®’s tubing provides a variety of higher strength alternatives. Custom steels are available such as HSLA and DS.

Outstanding Corrosion Protection

Allied Tube & Conduit®’s signature in-line galvanizing process exhibits superior corrosion resistance by utilizing a triple layer of protection.  First a 99.99% pure SHG zinc coating is applied to the surface, followed by a conversion coating. The process is completed by adding a clear organic topcoat that seals the surface and produces a smooth shiny finished product unique to Allied Tube & Conduit®.

Weld Friendliness

Due to its 99.99% pure SHG zinc coating, Allied Tube & Conduit® tubing can be easily welded. Contrary to popular belief, all galvanized products do not perform identically in regards to welding suitability. Weld performance is an important feature of the Allied Tube & Conduit®’s tubing product.


Allied Tube & Conduit®’s tubing is also capable of being fabricated using several different methods including hole-punching, cutting, flattening, bending, swage, etc. All of these operations can be performed without cracking, flaking or otherwise damaging the integrity of the coatings. This is one of the unique advantages of Allied’s in-line galvanized process.

Custom Mill Lengths

There is nothing standard about our mill cut lengths. Custom mill lengths from Allied Tube & Conduit® allow you to minimize the scrap generated when having to cut standard lengths of pipe products.
