Future-ready corrosion protection compliant with Germany’s latest ZTV-ING standard
Hempel’s coating systems are now certified to Blatt 100, delivering long-term durability, sustainability and compliance for bridge and infrastructure projects across Germany.
The new standard for bridge corrosion protection
Blatt 100 is the latest update to ZTV-ING Section 4-3, introduced in February 2025. Developed by BASt and the Federal Ministry for Digital and Transport (BMDV), it replaces multiple legacy corrosion protection standards with one unified framework.
The new regulation simplifies specification processes while setting higher requirements for durability, sustainability and performance in infrastructure projects.

A modular approach to corrosion protection
Blatt 100 defines four system modules tailored to different substrates and project conditions:
-
Module A – Steel (New build & refurbishment)
- High-performance coating systems for abrasive-blasted steel (Sa 2½)
- Service life: up to 50 years
-
Module B – Surface-tolerant steel
- For maintenance projects with limited surface preparation
- Service life: approximately 25 years
- For maintenance projects with limited surface preparation
-
Module C – Hot-dip galvanised steel
- Duplex systems combining galvanizing and coating
- Service life: up to 50 years
-
Module D – Thermal spray zinc
- For metallised steel structures
- Service life: up to 50 years
- For metallised steel structures
Each module defines coating build-up, application requirements and quality control criteria to ensure consistent and verifiable performance.
Supporting sustainable infrastructure
Blatt 100 promotes long-term environmental and economic value by extending maintenance intervals and reducing emissions linked to repainting cycles.

Frequently asked questions about Blatt 100
-
What is Blatt 100?Blatt 100 is a German standard for corrosion protection of steel structures in infrastructure projects. It is part of ZTV-ING Section 4-3 and was introduced in February 2025 to modernise and simplify existing regulations.
-
What does Blatt 100 replace?Blatt 100 replaces several legacy TL standards, including TL Blatt 87, 89, 90, 91, 92, 93, 94, 95 and 97, consolidating them into one unified system.
-
What service life does Blatt 100 require?Blatt 100 is intended to support a bridge design life of 100 years by defining corrosion protection systems that can achieve refurbishment intervals of around 50 years.
This approach reduces lifecycle costs and minimises disruption caused by major maintenance activities. -
What are the four modules in Blatt 100?The standard defines four modules:
- Module A: Steel (new build and refurbishment)
- Module B: Surface-tolerant steel systems
- Module C: Hot-dip galvanised steel (duplex systems)
- Module D: Thermal spray zinc systems
-
How does Blatt 100 improve sustainability?Blatt 100 supports sustainability by extending maintenance intervals, reducing lifecycle emissions, lowering solvent content in coatings and improving long-term durability.
-
Are Hempel coating systems compliant with Blatt 100?Yes, Hempel offers certified coating systems that meet Blatt 100 requirements, helping ensure compliance, durability and performance in infrastructure projects.
-
What are the benefits of using Hempel for Blatt 100 projects?Hempel provides advanced technologies such as Avantguard®, low-VOC coatings, easy application and reliable supply across Europe, supporting efficient project execution and long-term protection.
