EN 10025 hot rolled structural steel products: production lines and available specifications

Product Overview

Hot rolled structural steel products are widely used in steel structures, bridges, machinery manufacturing, offshore engineering, and industrial construction.

At Union Steel Industry, structural steel products are supplied according to European standards such as EN 10025-2, EN 10025-3, and EN 10025-4, covering a wide range of H beams, I beams, channel steel, angle steel, flat bars, and steel round bars.

This article summarizes the certified production scope and available specifications covered under the EN 10025 structural steel system.

EN 10025 Standard Overview

The EN 10025 standard specifies technical delivery conditions for hot rolled structural steels.

Different parts of the standard correspond to different performance requirements:

EN 10025-2: Non-alloy structural steels

EN 10025-3: Normalized / normalized rolled weldable fine grain steels

EN 10025-4: Thermomechanically rolled weldable fine grain steels

These standards are commonly used in European structural engineering projects requiring stable mechanical properties and reliable weldability.

1. Hot Rolling Shaped Section Line

The hot rolling shaped section production line covers multiple structural profiles under different EN 10025 standards.

Under EN 10025-2:2019, the production scope includes S355J2 steel grade flat bars. The maximum specification for bulb flat steel reaches a width of 440 mm with thickness ranging from 7 mm to 12 mm.

Under EN 10025-3:2019, available steel grades include:

S275N / NL

S355N / NL

The products mainly include:

L sections up to 250 × 250 mm

C channels up to 400 × 200 mm

Under EN 10025-4:2019, thermomechanically rolled grades include:

S275M / ML

S355M / ML

The available section dimensions remain similar to those under EN 10025-3.

These structural profiles are commonly used in:

Building structures

Industrial platforms

Bridge support systems

Machinery frameworks

2. H Beam and I Beam Production Lines

Heavy H Beam Production Line

The heavy section production line is designed for large structural applications with high load-bearing requirements.

The production capability includes:

H beams up to 1000 × 302 mm

Thickness range from 12 mm to 40 mm

I beams up to 630 × 180 mm

Thickness range from 11.5 mm to 17 mm

Large-size H beams are widely used in:

High-rise steel structures

Shipbuilding projects

Heavy industrial workshops

Infrastructure construction

Medium H Beam Production Line

The medium-size production line covers:

H beams up to 400 × 200 mm

I beams

C channels

L sections

These products are suitable for medium-load structural systems and general steel fabrication projects.

Light H Beam Production Line

The light section line mainly produces:

H beams up to 200 × 100 mm

I beams

C channels

L sections

This production line also includes weather-resistant steel grades such as S355J0W, which are commonly used in outdoor structural environments requiring improved atmospheric corrosion resistance.

3. Steel Round Bar Production Lines

The steel round bar production system includes multiple rolling lines dedicated to special steel products.

Available Diameter Range

16 mm to 320 mm

Main Standards

EN10025-2:2019

Common Steel Grades

S355JR

S355J0

S355J2

Steel round bars in these grades are widely used for:

Mechanical components

Structural connections

Forging applications

Engineering equipment manufacturing

The wide diameter range allows the products to meet both light-duty and heavy-duty industrial requirements.

Production Capability and Project Applications

The certified production scope demonstrates the capability to supply multiple categories of structural steel products under unified European standards.

For engineering buyers, this provides several advantages:

Stable material traceability

Standardized mechanical performance

Multi-size project supply capability

Compatibility with European construction specifications

In practical projects, combining H beams, channels, angles, and round bars within the same standard system helps improve procurement efficiency and structural compatibility.
