Mark Steel Corporation


For 45 years, Mark Steel has manufactured vessels, plate steel, and structural steel under ASME Section 8, Division 1 and AISC’s specifications, codes and standards.  If an industry requires this work and is located in Western North America, then, more than likely, we have fabricated steel for it.

In our recent history, our work has been placed into service in refineries, mines, oil and gas production, mid-stream operations, oil shale processing, cement kilns, power plants, aerospace, fertilizer plants, ammonia plants, radioactive waste facilities, smelting, and chemical processing.  Our work is destined for demanding, extreme conditions and serious uses.  We take pride in serving these industries with our quality work.
