Steel structures in industrial plants are exposed to constant stresses such as chemical vapours, temperature fluctuations and mechanical wear. Stair towers, access bridges and load-bearing frames form the functional frame of the plant. Their condition has a direct impact on safety at work and the lifetime of the site. Maintenance painting is a technical investment to stop the progress of corrosion. If the steel is allowed to corrode freely, the load-bearing capacity of the structure is reduced. This ultimately leads to costly demolition and rebuilding that could be prevented by timely maintenance. <\/p>\n

Professional industrial painting is based on standardised processes and a careful choice of materials. Predictive maintenance painting has been proven to be the most economically efficient way to manage industrial real estate mass. Data collected by NACE International, for example, shows that uncontrolled corrosion is a huge cost to industry. A significant proportion of these costs can be avoided with the right surface treatment. In Finland’s demanding conditions, such as the maritime climate or chemical exposure, the requirements for coating durability are exceptionally high. <\/p>\n

Corrosion protection and structural integrity of steel structures<\/h2>\n

Corrosion of steel is an electrochemical process. It requires oxygen and moisture to occur. In industrial environments, this process is often accelerated by chemical residues, salts and large temperature differences. The purpose of the surface treatment is to form a tight protective layer between the steel and the outside air. In demanding environments, multi-stage coating systems are used. The primer, intermediate and topcoat each play their own technical role in ensuring the durability of the whole. <\/p>\n

\n

Corrosion classes and requirements (ISO 12944)<\/h4>\n
C3 (Moderate)Urban and industrial environments<\/strong><\/div>\n
C4 (Ankara)Industrial and coastal areas<\/strong><\/div>\n
C5 (Very harsh)Aggressive chemical environments<\/strong><\/div>\n<\/div>\n

The ISO 12944 standard guides the quality of industrial painting. In practice, when specifying C5 protection for an object, it requires a very thick and chemically resistant coating layer. Such a coating protects the steel even under direct chemical stress. Maintaining the correct classification prevents premature flaking or bubbling of the coating. This ensures a long service life and reduces the need for production-disrupting repairs. <\/p>\n

Careful pre-treatment is the basis for quality. In industrial maintenance painting, this often means spray cleaning to at least Sa 2\u00bd. This method removes old paint, rust and contaminants. Without a clean and sufficiently rough surface, the paint will not adhere reliably. Poor adhesion allows moisture to penetrate beneath the coating, allowing corrosion to continue invisibly within the structure. <\/p>\n

Stair towers and treatment platforms: safety and mechanical durability<\/h2>\n

Stairwells and service platforms are critical access routes for industry. Their condition has a direct impact on day-to-day occupational safety. Surfaces must be able to withstand constant mechanical wear and tear, such as footsteps and impacts from machine tools. A worn or rusty step is a risk factor that can lead to slips or structural failure. Kotek Factory Service Ltd carries out these demanding jobs with professionalism.

Epoxy systems are typically used for painting stair towers due to their good adhesion and hardness. For exteriors, polyurethane paint is often chosen as a topcoat to protect the surface from UV radiation. Polyurethane prevents surface chalking and colour fading. It keeps the protective layer flexible for longer than epoxy alone. This extends the service life and significantly reduces the life cycle cost of the structure. <\/p>\n

Particular attention should be paid to joints, bolts and weld seams. These are often the points where corrosion starts. A good quality industrial paint job includes a stripe coat on these areas with a brush. This ensures adequate film strength in sharp edges and crevices before spray painting. This technical step is crucial when aiming for a lifetime of decades. <\/p>\n

Strategic maintenance and economic benefits<\/h2>\n

In maintenance planning, the economy drives decisions. Maintenance painting of steel structures and stair towers is part of life cycle management. The aim is to maximise the service life of the structure and minimise the repair debt. Studies show that the cost of corrosion in industrialised countries is equivalent to around 3-4% of GDP. A large part of this amount can be controlled by timely surface treatment. <\/p>\n

The timing of the maintenance painting is crucial. If coating damage progresses too far (for example to the corrosion level Ri3), the cost of pre-treatment will increase significantly. In such cases, patch painting is no longer sufficient and the entire structure must be cleaned down to the clean metal by spray blasting. Proactive industrial painting saves labour costs and prevents production stoppages due to structural defects. <\/p>\n

\n

Paint system durability classes (ISO 12944-1)<\/h4>\n
L (Low)up to 7 years<\/strong><\/div>\n
M (Intermediate)7 – 15 years<\/strong><\/div>\n
H (High)15 – 25 years<\/strong><\/div>\n
VH (Very High) over 25 years<\/strong><\/div>\n<\/div>\n

When aiming for a very long service life (H or VH), the Dry Film Thickness (DFT) of the coating becomes more important. The protective film must be thick enough to prevent water vapour and ions from entering the steel surface for decades. In professional work, the thickness of each layer is verified by electronic gauges. This ensures that the technical plan is accurately implemented at every point. <\/p>\n

Special coatings for challenging industrial environments<\/h2>\n

Not all sites are the same. The chemical industry, sewage treatment plants and food processing plants have requirements for coatings that cannot be met by conventional paints. For these applications, special materials such as polyurea or ARC composite coatings are used. High-quality metallic coatings<\/a> ensure that parts are resistant to acids, alkalis and abrasive wear. <\/p>\n

\n
\n
ARC composites<\/h5>\n

Chemical resistance and protection against erosion in demanding tanks and pumps.<\/p>\n<\/div>\n

\n
Polyurea coatings<\/h5>\n

An elastic and fast-drying surface that is resistant to temperature fluctuations and vibrations.<\/p>\n<\/div>\n

\n
Epoxy systems<\/h5>\n

Mechanical hardness and excellent adhesion to steel structures indoors.<\/p>\n<\/div>\n<\/div>\n

Our versatile industrial paint shop services<\/a> also allow you to handle components under controlled conditions. Removable treatment platforms and handrails can be treated in the paint shop. This ensures the best quality without the risks of weather conditions or dust on site. On-site work emphasises the specialist’s ability to control conditions such as dew point to ensure optimum adhesion of the coating. <\/p>\n

Maintenance painting of steel structures is a combination of technical expertise, precise pre-treatment and quality assurance. It is an investment that pays for itself in terms of extended service life and controlled costs. For demanding industrial plants and critical steel structures, compromising on quality is an economic risk. A competent partner ensures that the project is completed on time and to technical standards. <\/p>\n
