Technical specifications and applications of steel tubes according to the EN 39 standard
The European standard EN 39 regulates the production and supply of precision non-alloy steel tubes, optimized for use in scaffolding and formwork systems. Products supplied by EV Group China fully comply with the established standards for geometry and mechanical properties, ensuring high load-bearing capacity of structures.
The standard specifies requirements for tubes with the following wall thickness parameters:
- 3.2 mm
- 4.0 mm
This type of metal product is intended for use in conjunction with connectors (couplers) certified according to the EN 74 standard. This ensures the reliability of connection points when erecting temporary load-bearing structures of any complexity.
Operational features and standardization
EN 39 standard tubes with an outer diameter of 48.3 mm are the industry safety standard. Specialists at EV Group China highlight the following important aspects of their application:
- Versatility: Products can be integrated into prefabricated frame systems together with other sizes of non-alloy steel tubes, which expands the design possibilities for construction scaffolding.
- Regulatory framework: The use of tubes must strictly comply with current international regulations, including the requirements of the EN 12811 and EN 12812 series standards, which regulate the safety of temporary construction structures.
EV Group China ensures complete quality control during the stages of marking, acceptance testing, and laboratory testing, which is confirmed by the relevant technical documentation for each batch of metal products.
