Solutions that Support Production
01
Surface Treatment Consulting
We help manufacturing companies identify the best solutions, develop their own surface treatment processes, or plan a new paint shop, including investment calculations.
With over 30 years of practical experience, we optimize material selection, equipment, and production processes (such as OEE monitoring and ERP integrations). Our expert consulting services ensure that you avoid unnecessary costs, quality issues, and production inefficiencies.
02
System Delivieries
We deliver fully integrated and optimized solutions for the handling and assembly of materials and products.
In addition to surface treatment, we source necessary components on your behalf, execute precision assembly, handle final packaging, and manage storage. A comprehensive turnkey solution reduces total cost of ownership and guarantees predictability in the supply chain.
03
Outsourcing Surface Treatment
We analyze whether managing an in-house surface treatment process serves your strategy, or if outsourcing delivers a superior financial and operational outcome.
Partnering with Löfs frees up internal resources, eliminates the need for heavy capital investments, and secures certified, uncompromised quality under all market conditions.
Certified Quality Architecture of the Powder Coating Process
Pretreatment
Careful and proper surface preparation is the foundation of high-quality powder coating. We perform mechanical and chemical pretreatments in accordance with the industry’s strictest standards to ensure perfect adhesion and corrosion protection for the coating.
Painting
The paint is applied to the surface of the workpiece as a fine powder using an electrostatic process. This method produces an even, thick, and extremely durable coating without solvent or VOC emissions.
Hardening
The parts are heated to a high temperature, causing the powder to melt and form a strong bond with the metal surface. This ensures excellent mechanical and chemical wear resistance.
Quality Assurance
Our certified inspectors oversee the process. If necessary, we create a project-specific quality assurance plan, and the surface treatment meets the requirements of the SFS-EN ISO 12944 standards.
Corrosion Classes
Certified Corrosion Protection for the Most Demanding Environments
When deciding on a surface treatment method for a product, it is critical to determine where and under what conditions the product will be used. Löfs performs demanding powder coating projects in accordance with climate exposure classes C1–C5 of the international SFS-EN ISO 12944 standard.
Careful mechanical and/or chemical pretreatment, along with closely monitored processes, ensure that the coating can withstand even the harshest industrial and marine environmental conditions. Our experts are always available to help you select the correct classification and the coating system best suited to your application.
C1 – Very low risk of corrosion
ENVIRONMENT
Heated indoor spaces with dry air and low levels of pollutants (e.g., offices, stores, hotels). Not for outdoor use.
Löfs execution
A cost-effective single-coat painting process that focuses on achieving a clean, even, and visually flawless finish.
C2 – Low risk of corrosion
ENVIRONMENT
Outdoors: a small amount of pollutants (rural environment). Indoors: unheated spaces where temperature and humidity vary (e.g., warehouses and sports halls).
Löfs execution
A single-coat, high-quality powder coating that protects items from weather fluctuations in indoor and sheltered outdoor environments.
C3 – Moderate corrosion risk
ENVIRONMENT
Outdoor urban and industrial air. Indoors, moderate humidity and some pollutants (e.g., breweries, dairies, laundries).
Löfs execution
Careful pretreatment and high-quality powder coating for industrial machinery and equipment components.
C4 – High corrosion risk
ENVIRONMENT
Outdoor industrial and coastal areas with significant levels of pollutants or moderate salt concentrations. Indoor areas with high humidity (e.g., chemical plants, shipyards).
Löfs execution
Coating of demanding applications, such as the body parts of forestry machines and trailers, using a multi-layer system (primer and topcoat).
C5 – Very high risk of corrosion
ENVIRONMENT
Industrial and offshore areas characterized by a harsh climate, high humidity, and high salt content.
Löfs execution
Pre-treatment that meets the highest standards and customized, certified powder coating solutions for extremely harsh environmental conditions.

Frequently Asked Questions About Powder Coating
We serve manufacturers in the metal, machinery, and equipment industries by offering industrial-scale capacity and uncompromising quality. Below, you’ll find answers to the most common questions related to powder coating and Löfs’ services.
Powder coating is at its best in applications where the coating must provide exceptional mechanical durability, weather resistance, and a clean, even finish. Powder coating is ideally suited for a wide range of industrial applications, such as:
For large-scale mass-produced products where the quality and thickness of the coating must remain completely identical from one piece to the next.
Frame and body structures of machinery and equipment, such as parts for agricultural, forestry, and earth-moving machinery
For industrial metal components and castings
For steel structures, profiles, and sheets intended for outdoor use, such as deck railings, fences, and facade elements
For enclosures and cabinets in the electrical and electronics industry
We specialize specifically in powder coating metal parts, such as steel, galvanized steel, and aluminum. The electrical conductivity of metals ensures optimal adhesion of the coating powder and a high-quality finish. With our modern production lines, we can efficiently handle everything from complex castings and large production runs to sturdy and heavy steel structures.
Colors can be chosen with virtually complete freedom. Our in-stock selection covers the most common standard industrial colors, ensuring the fastest and most cost-effective turnaround. If a project requires a custom-made or customer-specific shade, we will order or manufacture the paint separately. For special shades, we’ll include any additional costs directly in the quote to ensure there are no surprises in the supply chain.
When it comes to surface types, we are experts in both completely smooth surfaces and textured surfaces that offer excellent resistance to mechanical wear, depending on the product’s intended use.
Powder coating does not use any solvents at all, which means the process does not produce any harmful VOC emissions. The method is also highly material-efficient: powder paint that falls off the production line is carefully collected and reused, minimizing waste. In addition, at Löfs, we recycle the waste heat generated by our paint ovens directly to heat our own facilities, which further reduces our carbon footprint.
Yes, they do. We perform and document surface treatments in accordance with the international SFS-EN ISO 12944 standard for climate exposure classes C1–C5. Careful mechanical and chemical pretreatment, as well as multi-layer systems (primer + powder coating) when necessary, ensure that the coating withstands even the harshest industrial and marine conditions for a long time.
The cost of powder coating is primarily influenced by the batch size, the geometry and weight of the parts, the required pretreatment (such as blast cleaning or chemical washing), and the corrosion class required for the application. Because we have several modern production lines and high capacity, we are able to flexibly offer our industrial customers a comprehensive solution that always meets their needs. You can submit a request for a quote directly via the form on our website or contact our sales team.
Powder coating, also known as powder painting or thermal spraying, is an industrial surface treatment method in which paint is applied to the surface of a workpiece as a dry powder via electrostatic spraying. After spraying, the parts are transferred to a curing oven, where the paint powder melts at a high temperature and fuses to the metal surface. The result is an extremely hard, flexible protective coating that is resistant to mechanical wear and corrosion, making it ideal for demanding industrial applications.
