Thermal Spraying for Extreme Atmospheric and Mechanical Corrosion Barriers
Advanced Thermal Spraying Solutions for Heavy Industrial Environments
Löfs’ high-capacity thermal spraying production lines execute heavy-duty surface conditioning engineered specifically for massive structural elements requiring unyielding long-term performance. The automated application matrix guarantees uniform zinc thickness and mechanical durability, eliminating supply chain risk for large-scale individual components.
This non-thermal structural execution provides continuous process predictability without the risk of component warping, thermal deformation, or hydrogen embrittlement. Every coating stage operates under certified quality metrics to ensure absolute compliance with the heavy industry’s strictest corrosion specifications.

Thermal spraying
Thermal spraying (thermal coating, spray zinc coating) is a zinc coating method in which molten zinc is sprayed onto a pretreated metal surface using compressed air.
Spray coating produces a remarkably thick (on average 150 μm) protective layer. It provides exceptionally tough protection against both corrosion and mechanical abrasion and wear in heavy-duty industrial structures.

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 Thermal Spraying Process
Pretreatment
A perfect finish always requires a clean surface. We carefully prep metal parts by mechanically or chemically removing contaminants, rust, and mill scale. This ensures maximum and uniform adhesion of the zinc coating.
Coating
The parts are coated on our modern production lines using the selected method. In thermal coating, the correct film thickness—averaging 150 µm—is achieved through a standardized and metered spraying process. This ensures a completely homogeneous and pore-free protective layer that leaves no weak spots in critical structures.
Duplex finish (optional)
We offer a unique advantage: we can finish the galvanizing process by painting over the zinc coating using our own state-of-the-art painting lines. This Duplex treatment provides multiple layers of protection against highly corrosive environments (C4–CX) and allows you to apply your desired accent or brand color over the gray zinc surface.
Quality Assurance and Measurement
We accurately measure the thickness of the finished protective coating using digital film thickness gauges. Monitoring in accordance with our ISO 9001 system ensures that every batch meets the requirements of the standards and the tolerances specified by the customer.

Frequently Asked Questions About Thermal Spraying
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 galvanizing.
In zinc painting, the zinc is already present in the liquid paint itself, so it is applied to the surface just like regular paint. In true thermal spraying, a pure, metallic layer of zinc is formed on the metal surface by mechanically melting and spraying a wire with compressed air. Zinc painting is an excellent repair and priming method, but it does not provide the same mechanical wear resistance as heavy-duty thermal zinc coating.
In our modern production facilities, a large portion of the waste heat generated by our production lines and processes is recovered and used to heat our buildings. This significantly reduces our total energy consumption and carbon footprint. For industrial buyers, this means not only a more responsible supply chain but also greater cost efficiency, as energy waste is minimized through careful planning.
