What is BS EN 1993-4-2:2010?

BS EN 1993-4-2:2010, also known as Eurocode 3 - Design of steel structures - Part 4-2: Tanks, is a European standard that provides guidance for the design and construction of steel storage tanks. It covers various aspects such as materials, structural analysis, stability, and integrity requirements.

Why is it important?

Steel storage tanks are widely used in industries for storing various liquids, including water, oil, chemicals, and fuels. The safe and reliable design of these tanks is crucial to prevent leakage, structural failures, and environmental hazards. BS EN 1993-4-2:2010 plays a vital role in ensuring the structural integrity and safety of steel tanks.

Key provisions of BS EN 1993-4-2:2010

1. Materials: The standard specifies the requirements for the selection and quality control of steel materials used in tank construction. It covers both the base material and the welds.

2. Structural analysis: BS EN 1993-4-2:2010 provides guidelines for the structural analysis of tanks under various load conditions. It considers factors such as dead load, live load, wind load, and seismic load.

3. Stability: The standard addresses the stability requirements for different types of tanks, such as vertical cylindrical tanks, rectangular tanks, and elevated tanks. It includes provisions for the prevention of buckling, overturning, and sliding.

4. Integrity requirements: BS EN 1993-4-2:2010 outlines the criteria for assessing the integrity of tanks, including leakage prevention, corrosion protection, and inspection procedures.


BS EN 1993-4-2:2010 is a crucial standard that provides comprehensive guidelines for the design and construction of steel storage tanks. It ensures the structural integrity, stability, and safety of these tanks, minimizing the risk of leakage, failures, and environmental contamination. Adhering to this standard is essential for industries that rely on steel tanks to store liquids safely and efficiently.
