Fabricated Steel Beams For Chernobyl Nuclear Reactor Clean-up
As discussed in several of our 2012 steel fabrication blog posts, J & J has played an essential role in the manufacture of the Main Crane System that will eventually be used to aid in the safe cleanup of the contaminated nuclear reactor site in Chernobyl, Ukraine.
The photo below shows the North and South Runway Beams that were installed in the building where components of the Main Crane System are being assembled. These steel fabrications were constructed with ASTM A572 steel plate and ASTM A992 structural steel. Each beam weighs over 11,000 pounds and measures 25” high x 47” wide x 665” long.

J & J Burning and Fabricating produced this Die Table for the Aerospace Industry. This stretch forming press weighs over 40,000 pounds and will be part of a steel stretch forming machine.
Stretch forming is a process in which steel sheets are formed into profiles wrapped around dies to make parts into simple or complex contoured curves. The Aerospace Industry utilizes these very accurate and repeatable stretch forming presses to manufacture critical fuselage skins for commercial and business aircraft. The stretch forming presses are also used to create the curved profiles that comprise the aircraft’s frame.
J & J Burning and Fabricating Company is excited to announce the addition of a new generation high definition plasma cutting machine.
Utilizing this superior technology, J & J is able to greatly reduce cutting time while producing high quality parts that are ready for assembly with no clean up required. We have achieved cutting speeds 7x faster than can be performed on standard burning machines. Parts from 10 gage to 3” thick have clean edges and a very tight tolerance of .030” with less than a 1 degree draft. The expertise associated with this equipment has truly revolutionized the metal cutting industry.
In addition to our new plasma cutting equipment, we have rebuilt two of our burning machines and upgraded to the latest designs for CNC technology. The rebuilt plasma machine can cut up to 1 1/4” thick mild steel, stainless steel and aluminum with its new Hypertherm torch. The oxy-fuel machine can burn up to 16” thick mild steel. Both of these machines are now outfitted with state of the art computers that run up to 8x faster allowing for better utilization of the material and reduced processing times.
