Exterior Tank Coatings
Exterior Tank Coatings
Protecting Storage Tanks From the Outside In
A storage tank’s exterior is its first line of defense against the surrounding environment. Sunlight, rain, humidity, temperature swings, airborne chemicals, and industrial pollutants can gradually break down protective finishes and expose the steel beneath. Once corrosion begins spreading across the shell, roof, structural components, or fittings, it can become a larger maintenance concern. External tank coatings help provide a durable protective layer designed specifically for outdoor exposure.
Metercheck provides exterior coating services for storage tanks where maintaining the outside surface is an important part of asset upkeep. We look at the tank as a complete structure rather than treating coating as a simple painting project. The condition of the existing finish, areas of corrosion, accessibility, weather conditions, and the tank’s operating environment all influence how the work is approached.
More Than a Fresh Coat of Paint
Exterior tank coating serves a functional purpose beyond improving appearance. A properly selected coating system helps separate the tank’s steel from moisture and other environmental elements that can contribute to corrosion. It can also give operators a uniform surface that makes future visual inspections and maintenance easier.
Before work begins, the tank exterior is examined for signs of coating failure, rust, peeling, cracking, blistering, and other surface conditions. This assessment helps identify areas that may require additional preparation or attention before a new coating is installed.
For tanks that have spent years exposed to the elements, simply applying another layer over an aging finish may not provide the desired result. Removing unsound material and preparing the substrate correctly gives the new coating a better foundation.
Coating Large and Hard-to-Reach Areas
Storage tanks can have extensive exterior surfaces, including curved shells, roofs, stairways, platforms, nozzles, supports, and other components. Working around these features requires careful planning to achieve complete and consistent coverage.
Metercheck organizes the coating process around the physical characteristics of the tank and the requirements of the facility. Access equipment, work zones, surface preparation, and application methods are considered before the project gets underway.
Particular attention is given to locations where water, dirt, or contaminants can collect. Welded areas, connections, roof sections, and other exposed components may require additional preparation to help prevent premature coating failure.
Built for Outdoor Exposure
Different storage facilities face different environmental challenges. A tank located in a dry climate may experience intense ultraviolet exposure and temperature fluctuations, while a tank in a humid or coastal environment may face significantly greater moisture exposure.
The coating system needs to match those conditions. Metercheck considers the tank’s surroundings and service requirements when determining the appropriate approach to External tank coatings. The objective is to establish a protective finish that can withstand the environment rather than selecting a coating based solely on appearance.
Application conditions matter as well. Weather and surface conditions can affect how coatings bond, cure, and perform. Our team accounts for these factors when scheduling and carrying out exterior coating work.
Keeping Corrosion From Becoming a Bigger Problem
Exterior corrosion can develop gradually, making routine maintenance valuable for identifying deterioration before it becomes more extensive. Maintaining the protective coating can help limit direct environmental exposure to the steel and support an ongoing corrosion-management strategy.
Exterior coating work may be performed as part of a larger tank maintenance project or during a planned refurbishment. Addressing deteriorated coating and surface corrosion at the appropriate time can help operators maintain the tank’s exterior condition and avoid allowing small coating failures to spread.
Metercheck brings together surface preparation, coating application, project planning, and safety practices to help deliver dependable exterior tank coating work. With properly maintained External tank coatings, storage tank owners can give their equipment an added layer of protection against the demanding conditions found around industrial facilities.
