What is DIN 4944-05:1989?

DIN 4944-05:1989 is a technical standard that specifies the requirements for corrosion protection of steel

structures by applying metallic or organic coatings. It defines the various methods, properties, and

measurements needed to ensure effective corrosion protection. Let's explore the details of this standard to

gain a better understanding.

DIN 4944-05:1989 Structure and Scope

The DIN 4944-05:1989 standard consists of several sections that cover different aspects of corrosion protection.

These sections include:

Section 1: Introduction, including the purpose and scope of the standard.

Section 2: Terms and definitions used throughout the document.

Section 3: General principles of corrosion protection, including surface preparation and coating application.

Section 4: Metallic coatings, covering requirements for hot-dip galvanizing, electroplating, and sherardizing.

Section 5: Organic coatings, specifying the properties and test methods for paints, varnishes, and powder coatings.

Section 6: Measurement methods for evaluating the quality and durability of the applied coatings.

Why is DIN 4944-05:1989 Important?

Corrosion protection is vital to ensure the longevity and performance of steel structures, as corrosion can

significantly weaken them over time. The application of appropriate coatings helps prevent corrosion by creating

a barrier between the steel surface and environmental factors such as moisture, chemicals, and oxidation.

DIN 4944-05:1989 provides engineers, architects, and manufacturers with standardized guidelines and reference

values for corrosion protection methods. By adhering to this standard, professionals can achieve consistent and

effective corrosion resistance, leading to improved durability and reduced maintenance costs for steel structures.


DIN 4944-05:1989 plays a crucial role in ensuring the long-term reliability and safety of steel structures by

providing comprehensive guidelines for corrosion protection. This technical standard covers different aspects of

surface preparation, coating application, and measurement methods, enabling professionals to attain consistent

and reliable results.

With widespread implementation of DIN 4944-05:1989, we can expect improved protection against corrosion and

enhanced durability of steel structures across various industries.
