The applicaitons of EN 39 S235GT
1. Scaffold system:
- EN39 S235GT steel pipe is the ideal material for the manufacture of scaffolding, especially in construction and maintenance projects. They are used to build safe and stable platforms for workers working at high altitudes.
2. Temporary working platform:
- These steel pipes are used to construct scaffolding, providing a safe and stable platform for workers working at altitude in construction, maintenance and repair projects.
3. Support system:
- EN39 S235GT steel pipes are used to support the walls of excavation operations to prevent collapse and ensure worker safety.
4. Template support:
- These steel tubes are used to create support systems that support the formwork of the concrete structure, ensuring that the formwork remains stable during the pouring and curing process.
5. Temporary structure:
- EN39 S235GT steel pipe is often used in the construction of temporary structures such as event stages, stands and tents, and its strength and versatility make it suitable for creating stable and reliable frames.
6. Temporary shelter in case of emergency:
- In emergency situations, EN39 S235GT steel pipes can be used to quickly construct temporary shelters and housing, providing a fast and reliable solution for disaster areas.
7. Demolition work:
- EN39 S235GT Scaffolding tubes are used to create temporary structures to support a building or part of a building during demolition, ensuring that the demolition work is carried out safely and efficiently.
8. Transportation and Logistics:
- EN39 S235GT scaffolding tubes are used to construct temporary loading platforms and ramps to provide access to loading and unloading materials for transport and logistics operations.
9. Marine and offshore applications:
- EN39 S235GT steel pipes are also used in scaffolding systems for ship construction and maintenance, as well as scaffolding systems for offshore oil RIGS, where safe access to high places is required.
