DETAILED INFORMATION
EN 39 Hollow Section is a steel pipe material conforming to the European standard EN 39, which is commonly used in construction, temporary structures and other fields.
Peculiarity of EN 39 HOLLOW SECTION
High strength:
The EN 39 Hollow Section has high tensile strength and yield strength and can withstand large loads.
For example, S235GT grade steel pipe yield strength of 235 MPa, tensile strength of 340-520 MPa.
Good structural integrity:
The material's dimensional consistency and tight tolerance controls ensure rapid assembly and disassembly during construction.
Durability:
EN 39 steel pipes are usually hot-dip galvanized and have good corrosion resistance, suitable for use in harsh environments.
Easy to install:
High dimensional consistency, good welding performance, easy to quickly assemble on site.
Cost effectiveness:
Due to its durability and reusability, long-term use costs are low.
Environmental protection:
Steel can be recycled and is an environmentally friendly material.
Application fields
Scaffolding system:
It is used for building construction, maintenance and repair projects to build safe and stable high-altitude working platforms.
Including ordinary scaffolding, cantilever scaffolding, etc.
Support system:
It is used to support the wall in the excavation of foundation pit to prevent collapse.
Formwork support for concrete structures to ensure stability during pouring and curing.
Temporary structure:
For the construction of event stage, stands, tents and other temporary facilities.
In case of emergency, it can be used to quickly set up temporary shelters.
Demolition works:
During the demolition process, it is used to build temporary support structures to ensure the safety and efficiency of the demolition work.
Transportation and Logistics:
Used to build temporary loading platforms and ramps.
Marine and offshore applications:
Scaffolding systems for shipbuilding, ship repair and offshore platforms.
