EN 10219-UNIASEN-PILING PIPE

EN 10219

EN 10219 specifies the requirements for cold-formed welded structural hollow sections of cold-formed, non-alloy, and fine-grain steel tubes.

The standard is divided into 3 parts. The first part includes the technical delivery requirements of EN 10219 tubes. Part 1 covers the tolerances, dimensions, and cross-sectional properties of EN 10219 tubes. Part 3 is the technical delivery conditions of EN 10219 tubes for high-strength and weathering steel.

This standard is commonly used in the construction of steel structures, civil engineering, and the installation of oil, gas, water or electricity pipelines.
