Sat hours are 8:00am - 12:00pm.

Steel is produced through a variety of ways using iron ore and various types of scrap metals. Through the steel making process impurities are removed from the iron such as silicon, nitrogen, phosphorus, sulfur and carbon. Differing elements like manganese, nickel and chromium are then added to the iron to create a wide range of steel products.


Steel Applications

Steel products are utilized in nearly every industry imaginable. The use of steel is so widespread that it would be tough to imagine a world without it. Some of the larger industries that regularly utilize steel production, include:
  • Construction
  • Automotive
  • Machinery
  • Metal Products
  • Energy
  • Appliance Manufacturing

Steel Benefits

Steel is one of the most trusted and versatile manufacturing materials available. This premium material is reliable and regularly used in a bevy of industries. The benefits of steel products include:
  • Design Flexibility
  • Durability
  • Quality
  • Cost Efficiency
  • Recyclability
  • Low Emissions

Advanced Steel Products

We carry numerous types of steel, along with a wide selection of shapes and sizes to cater to all your steel production needs. Each specific type of steel has its own unique qualities that make it ideal for its given application. The types of steel products we carry are listed below.


ASTM A36 is one of the most widely used structural steel alloys. A36 is a type of steel that is available in a wide range of shapes including: plates, bars, angles, beams, channels, and rounds. A36 steel is commonly used when you want to weld or bend the steel. Lately, designers and architects have used A36 steel in non-structural ways. A36 steel maintains a dark and grainy look, and when stained, it can look like a modern art painting. If you are in the Los Angeles area and you want to see our A36 steel distribution center, feel free to stop by, we appreciate visitors to our steel production facility.


Galvanized steel, per ASTM A653, is a material where zinc is applied to steel sheets through electroplating. By coating the sheets with zinc, it makes the metal much more resistant to corrosion. Although you can paint the steel to prevent it from rusting, the coating won’t be nearly as thick nor as protective as galvanized steel. There are different thicknesses of zinc coating that can be applied to the steel but, G60 or G90 are the two most common.
Additionally, not all galvanized steel looks the same. The size of the crystallites in the galvanized coating is called “spangle” and it will greatly alter the appearance of the galvanized sheets. Some galvanized sheets look uniform and this is called minimum spangle, whereas some crystallite can be ¼” – ½” in size.

ERW Tubing 

Electric Resistance Welded Tubing is the most common type of tubing out there. It starts with a strip of steel that is formed and then welded. ERW tubing is measured on the OD (unlike pipe which is measured on the ID). Among the different types of steel tubing, ERW tubing is the least expensive, but also the weakest of all the steel tubing varieties.

DOM Tubing 

DOM tubing, or drawn over mandrel tubing, is also called “seamless” tubing because it is virtually seamless. Like regular welded tubing, it begins with a strip of steel that is formed and welded. It is then drawn over a mandrel (hence the name DOM) which causes the tube to be virtually seamless. It also makes the tube more concentric, have closer tolerances, and stronger, by as much as 20%. It is more expensive than ERW tubing but not as expensive as chromoly tubing.

Chromoly Steel Tubing

As you probably guessed, Chromoly Steel tubing is a type tubing that is constructed from Chromoly steel. Chromoly steel is alloyed steel that has small amounts of chromium and molybdenum mixed in it, which makes the tube stiffer and stronger than ERW and DOM tubing. Chromoly steel tubing is usually available in the 4130 grade and can be heat-treated to make it even stronger. Although Chromoly tubing weighs the same as ERW tubing and DOM tubing, you can usually get away with using a slightly thinner wall versus ERW and DOM tubing.

Physical Properties of Steel

Steel products derive their mechanical properties from a combination of chemical composition, heat treatment and manufacturing processes. While the major constituent of steel is iron, the addition of very small quantities of other elements can have a marked effect upon the properties of the steel. The type of alloy added to the steel will determine the strength of the steel and affect other properties of the steel including ductility, toughness and weldability.
