Who We Are


Productivity means fast turn around on parts, and significant cost savings

Since 1999, Great Denver Iron has provided structural steel welding and fabrication for the commercial, industrial, manufacturing, and government sectors.

We operate out of one location in Denver near I-70 and Colorado Blvd. on 4975 Jackson St. We have a total of 20,000 sq feet of shop space. Our shop is fully automated with the addition of a six axis robotic plasma fabrication machine. It does the work of seven machines, faster than ever thought possible. It is extremely productive!

AISC Certified

Only 5% of all steel fabricators in the entire Western U.S. hold this certification!

Steel Fabrication

In-House Detailing & Fabrication of All Structural & Architectural Steel Elements.

Innovative & Accurate

Maintaining tolerances up to 1/32 of an inch, yet Steel Erectors can install 25% faster than historical rates.

The machine produces quality bolt holes approved for structural joints. The maximum hole diameter is 24” +. It can cut up to and including 1.25 inch thickness. It produces layout marks so there is no need for fit up for parts like clips and stiffners. It takes direct download from design software (X-Steel, SDS2, AutoCad and more). It cuts to length, copes with CNC accuracy, cuts slots, makes cutouts for bracing and knife connections, scribes text and piece marks, miter cuts, weld prep bevel cuts, rib I-Beams into T-Beams, cuts out any shape. This machine cuts parts to within 1/32 inch tolerance over the length of the part. The actual part tolerance is often tighter, as positioned repeatability of the cutting robot is 12 times more precise at 0.0026 inch accuracy.

We offer true 3-D fabrication capability to process beams, channels, HSS, angle, bar and plate on one single machine. This machine saves countless hours of material handling, since all operations on a piece are done in one place. All facets of processing are fully automatic. Our annual capacity can reach 10,000 tons annually.

We provide welding and fabrication for small and large sub assemblies and assemblies.

Along with standard structural items such as beams, columns, braces, base plates and connection plates, we can provide fabrication of most miscellaneous steel items. Stairs, railings, trash gates, bollards, ships ladders, steel supports for mechanical and electrical equipment. We also provide steel for Industrial apllications such as platforms, gratings, gates, rails, and ladders. We can handle large or small complex Industrial and Manufacturing parts fabriction.

All coating operations take place on site. We have the AISC Sophisticated Paint Endorsement P1, 2 and 3. We do on site sandblasting for pieces small and large (SP 6, or SP10). We have experience with all types of coatings from red oxide primer to 2 part epoxies. We can provide finished coat painting as well. We are less than 2 miles from the only Galvanizer in Colorado and through them we can easily provide galvanizing to our finished products.

Our experience, automation, and our understanding of the economics of a fabriction shop allow us to pass along significant savings to our customers.

Productivity means fast turn around on parts, and significant cost savings.
