Manufacturing standards

EN 10219 – Cold formed structural tubes

Suitable for most standard structural applications, including:

• industrial metal fabrication

• light to medium steel structures

• industrial and commercial buildings

This is the most commonly used solution, offering a strong balance between performance, availability and cost.

EN 10210 – Hot finished structural tubes

Recommended for applications with higher structural requirements, such as:

• heavily loaded structures

• projects with specific engineering requirements

• demanding industrial applications

The use of this standard is normally project-driven.

Steel grade

We mainly work with structural steel grade S355, in accordance with EN 10219 and EN 10210, and can evaluate other structural grades depending on project requirements.

Commonly considered qualities include:

• S355 JR – standard structural applications

• S355 J0 – applications with additional impact requirements

• S355 J2 – more demanding structural applications

The steel grade is assessed case by case, based on the application, technical specification and service conditions

Section types

Square hollow sections (SHS)

Defined by side × side × thickness.

Typical sizes:

• 40 × 40 × 2 mm

• 60 × 60 × 3 mm

• 80 × 80 × 3 mm

• 100 × 100 × 4 mm

Typical applications:

• columns and posts

• vertical structural elements

• frames and load-bearing structures

Square sections are commonly used where uniform load distribution and structural symmetry are required.

Rectangular hollow sections (RHS)

Defined by width × height × thickness.

Typical sizes:

• 60 × 40 × 2 mm

• 80 × 40 × 3 mm

• 100 × 50 × 4 mm

• 120 × 60 × 5 mm

Typical applications:

• beams and girders

• horizontal structural elements

• frames and secondary steel structures

Rectangular sections are preferred when directional strength and bending resistance are required.

Circular hollow sections (CHS)

Defined by outside diameter × thickness.

Typical sizes:

• Ø48 × 2 mm

• Ø60 × 3 mm

• Ø76 × 3 mm

• Ø114 × 4 mm

Typical applications:

• tubular steel structures

• industrial equipment

• architectural and technical applications

Circular sections are often selected for torsional resistance, uniform stress distribution and aesthetic considerations.

Thickness range

We typically supply structural steel tubes with thicknesses ranging from 1.5 mm to 6.0 mm, depending on the section, standard and application.

Commonly supplied thicknesses include:

• 2.0 mm

• 2.5 mm

• 3.0 mm

• 4.0 mm

• 5.0 mm

The selected thickness is determined by the structural function, load requirements and project specification, and is assessed on a case-by-case basis.

Lengths

Standard lengths

Structural steel tubes are commonly supplied in the following standard lengths:

• 6 metres

• 12 metres

Non-standard lengths

We also supply:

• intermediate lengths

• project-specific lengths

• cut-to-length solutions

This flexibility allows customers to:

• reduce material waste

• simplify fabrication and assembly

• optimise overall project costs

Non-standard lengths are frequently used in project-based supply and small to medium series.

Supply model

Our supply model is designed to meet the requirements of industrial B2B customers, with a focus on flexibility, clarity and execution reliability.

• Supply of small and medium series

• Project-based sourcing and delivery

• Purchase and sale strictly within the European Union

• Logistics adapted to the agreed delivery lead time

• Each supply analysed individually according to technical and logistical requirements

This approach enables a controlled, predictable and reliable supply process, aligned with real project needs.

Request for quotation

For an accurate and technically correct quotation, we kindly ask that your enquiry includes the following information whenever possible:

• section type (square, rectangular or circular)

• dimensions

• thickness

• applicable standard (EN 10219 or EN 10210)

• steel grade (e.g. S355 JR / J0 / J2, when applicable)

• quantity

• length (standard or cut to length)

• required delivery lead time

• delivery location

Providing complete technical information allows us to evaluate the most suitable supply solution and issue a clear and objective quotation aligned with your project requirements.
