Rolled Cylinders Fabrication
Precision Formed Cylinders for Industrial Applications
At Openex, we specialize in the precision rolling and fabrication of steel cylinders and seamless shells used across a wide range of heavy industries — including energy, petrochemicals, pressure vessels, construction, marine, and bulk storage. With more than ten state-of-the-art plate rolling machines in operation, we offer one of the most diverse forming capacities in the region.
Our rolled cylinders are used as standalone parts or as structural bases for vessels, silos, tanks, hoppers, pipelines, and mechanical assemblies. We can deliver shell segments with or without welding depending on your requirements for material integrity and assembly.
