Masts are exposed to harsh weather conditions, UV radiation, moisture, and pollution, making surface treatment essential to ensure long service life, functionality, and a pleasing appearance. A properly selected and applied surface treatment not only protects against corrosion but also reduces maintenance costs and significantly extends the lifespan of the mast.
Corrosion is one of the greatest threats to steel structures such as masts. Without effective protection, rust can quickly weaken the material, leading to structural deficiencies and increased maintenance expenses. Therefore, it is crucial to choose the appropriate surface treatment based on the mast’s use and the environment in which it is located.
Hot-dip galvanizing involves dipping the steel in molten zinc, creating strong cathodic protection against corrosion. This method is particularly effective in outdoor environments and requires minimal maintenance. Hot-dip galvanizing complies with the DS/EN ISO 1461 standard and is ideal for masts that must withstand harsh weather conditions.
Powder coating is an environmentally friendly and durable method where powdered paint is electrostatically applied and cured at high temperatures. The result is a uniform and impact-resistant surface that resists external influences. Powder coating is available in a wide range of colors and finishes, allowing for aesthetic customization of masts.
Metallizing, also known as thermal spraying, involves applying zinc or aluminum to the steel surface using a spray flame. This method offers effective corrosion protection and is especially suitable for structures exposed to extreme environmental conditions, such as offshore installations.
Wet painting is often used as an additional treatment on top of galvanizing or metallizing. This method provides a smooth and aesthetic finish and can be customized in different colors and gloss levels. Wet painting is well-suited for masts where high visual and corrosion protection standards are required.
It is important to select the correct surface treatment based on the mast’s location and application.
For masts placed in urban environments, powder coating may be beneficial for enhanced aesthetic appeal. For masts used in coastal or industrial areas, special precautions are often necessary to prolong mast longevity. In such cases, it may be appropriate to increase the thickness of the hot-dip galvanizing or apply powder coating.

To ensure high quality and longevity, surface treatments should be carried out in accordance with international standards such as DS/EN ISO 1461 for hot-dip galvanizing and DS/EN ISO 12944 for corrosion protection coating systems. Additionally, it is important to choose suppliers certified according to ISO 9001 (quality management), ISO 14001 (environmental management), and ISO 45001 (occupational health and safety).
A properly chosen and applied surface treatment is crucial for the mast’s durability, safety, and aesthetics. By considering environmental conditions, application, and relevant standards, one can ensure that masts remain functional and maintenance-free for many years.
