Bochumer Eisenhütte 
Bumaco has an exclusive partnership with Bochumer Eisenhütte, with a special focus on offshore hollow sections and pipes. Thanks to this collaboration, we can offer our customers high-quality products that meet the strictest requirements within the offshore industry.
Bochumer Eisenhütte is especially known as a leading supplier of profiles for both the mining and tunneling sectors. With decades of experience and in-depth material knowledge, they have built a strong international reputation, also within the on- and offshore sectors.
What distinguishes Bochumer Eisenhütte is their advanced heat treatment technology of profiles and pipes. Because Bumaco supplies the raw material, they can quickly and efficiently produce hollow sections according to offshore standards and quality, including testing and associated 3.1 or 3.2 certificate with CE marking.

a different standard
EN 10210 / EN10219: Standard for seamless and welded construction tubes of non-alloy and fine-grain steel
The EN 10210-1/2 standard is a European standard that sets requirements for hot-formed, welded, and seamless steel tube profiles for construction purposes of non-alloy and fine-grain steel types.
The EN 10219-1/2 standard is a European standard that describes the technical requirements for cold-formed welded steel tube profiles for construction purposes of non-alloy and fine-grain steel types.
Both standards were established by the European Committee for Standardization (CEN) and consist of two parts:
- Part 1 covers the technical delivery conditions.
- Part 2 specifies the tolerances, dimensions, and shape properties.
Tubes according to the EN 10210 standard are hot manufactured, resulting in improved mechanical properties, higher structural integrity, and better performance under heavy loads or low temperatures. EN 10210 tubes are particularly suitable for load-bearing structures where reliability is essential.
In cold forming according to the EN 10219 standard, the steel is formed into tube profiles without heat, resulting in sharp corners and precise dimensions. These tubes are widely used in situations where light weight, tight tolerances, and economic efficiency are important.
Application areas for which EN 10210 and EN 10219 pipes are intended:
EN 10210 and EN 10219 construction tubes are designed for construction applications where strength, dimensional accuracy, and weldability are essential, and are widely used in modern steel construction, mechanical engineering, and infrastructure projects.
Bridges and civil engineering structures
In bridge girders, support structures, portals, and masts due to the high strength-to-weight ratio and modular processability.
Offshore and maritime constructions
For parts of offshore wind turbines, platforms, and support structures where strength is important.
Machine construction and industrial installations
For frames, foundations, and support structures of machines, conveyors, and installations in industrial environments.
Infrastructure and urban applications
For applications such as traffic portals, light poles, noise barriers, and station constructions.
Architectural and aesthetic steel applications
Due to the sleek design of tube profiles, they are often used in visible work such as facade structures, stairs, canopies, and coverings.
