Using highest-quality 1006/1008 and 1010 cold-rolled steel, we produce an array of tight-tolerance welded annealed tubing for a diverse set of applications.

Most commonly used in heat transfer and refrigeration applications, our copper-electroplated steel tubing is available in a broad range of sizes and lengths.

Markin offers precision steel tubing with a copper coating on the inside diameter for strong protection against corrosion from caustic fluids.

We are proud to produce a range of steel tubing with a nickel coating on the inside diameter to handle fuels and other potentially-corrosive fluids.

Enhanced Galfan®-coating techniques yield our G2 coating, which is proven to deliver superior corrosion resistance in the most challenging environments.

Our proprietary Galfan® coating delivers outstanding corrosion resistance in accordance with ASTM B117, representing a cost-effective solution.
