For the past 45 years Mark Steel has fabricated structural steel in accordance with
AWS and AISC specifications, Tanks per API and AWWA specifications, and
pressure vessels in accordance with ASME VIII. 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.
