Definition - What does Field Coat mean?
Field coat is the protective layer applied at the site of installation or erection on structural steel and other materials to prevent corrosion. Field coats provide a boundary between the immediate material that is prone to corrosion and outer environmental or location elements that can facilitate corrosion.
Corrosionpedia explains Field Coat
When applying or choosing a field coat, it is vital to review all governing practices and supporting documentation that relate to the coat. Practices often lend detailed information about operational characteristics such as temperature, pressure and timing restraints that are best for optimal finish coat performance.
