Steel plants operate in very harsh environments, requiring cable and wire to withstand high heat and a lot of oil. At Marmon IEI, we understand the need for steel and aluminum manufacturers to rely on high quality thermocouple cables to keep production facilities running. We manufacture specialty cables for applications including heat treatment, component testing, furnace surveys and metal production. Our cables are engineered and constructed to withstand extreme heat, oil and molten metal that is found in such a highly abusive environment.
