What is ISO 14713?

ISO 14713 is officially titled:

"Zinc coatings — Guidelines and recommendations for the protection against corrosion of iron and steel in structures"

This standard is divided into three parts:

  1. ISO 14713-1:2017General principles of design and corrosion resistance
  2. ISO 14713-2:2019Hot dip galvanizing (after fabrication)
  3. ISO 14713-3:2017Electroplated and other zinc coatings

ISO 14713 serves as a comprehensive guide for selecting and applying zinc coatings based on:

⚙️ Environmental conditions

🔩 Type of steel structure or component

🧱 Design considerations to enhance corrosion resistance

🧪 Service life expectations and maintenance planning

This standard is widely used in construction, oil and gas, marine, agriculture, and automotive industries.

Why is ISO 14713 important?

Steel corrodes rapidly without protective coatings, especially in outdoor, coastal, marine, or industrial environments. Zinc coatings offer sacrificial protection, meaning they corrode in place of the steel, drastically extending the life of components.

ISO 14713 is essential because it:

✅ Helps select the right type of zinc coating for specific applications

✅ Defines design practices to improve coating performance

✅ Supports corrosion protection planning for long-term projects


What are the benefits of ISO 14713?

Implementing ISO 14713-compliant practices ensures better corrosion control and quality:

🛡️ Optimized Corrosion Protection

Matches coating type and thickness to environmental exposure.

📏 Improved Design for Durability

Offers structural design tips to prevent corrosion hotspots (e.g., avoiding water traps, sharp corners).

🔩 Standardized Galvanizing Processes

Covers both post-fabrication hot dip galvanizing and electroplating.

♻️ Eco-Friendly and Long-Lasting Solutions

Reduces need for repainting and maintenance, supporting sustainability.

🌍 Global Compliance and Market Acceptance

Accepted by contractors, OEMs, and regulators across global markets.
