EN 10219 Standard Definition:

The EN 10219 standard specifically addresses cold-formed welded hollow profiles. All square, rectangular, and round hollow profiles manufactured according to EN 10219 are welded pipes (welding processes include HFI/ERW, SAW, etc.). This standard strictly specifies: manufacturing process (cold forming + welding), dimensional tolerances (EN 10219-2), mechanical properties, chemical composition, and surface quality.

If your project requires the use of seamless tubing or hot-rolled hollow profiles, refer to EN 10210 (Hot-rolled Hollow Profiles).

S235JRH Meaning:

S: Structural Steel
235: Minimum yield strength of 235 MPa (applicable to wall thickness ≤ 16 mm)
JR: Impact energy at +20°C ≥ 27 J

H: Hollow Section

△S235JRH vs S235J2H: S235JRH only guarantees room temperature (+20°C) impact toughness (≥27 J), suitable for normal temperature environments and indoor structures; while S235J2H guarantees -20°C impact toughness, suitable for cold regions or winter construction environments.

Core Advantages of S235JRH Square Tubes:

1. Optimal Economic Efficiency
S235JRH is the lowest strength grade of structural steel under the EN 10219 standard, offering the most competitive price. For non-critical load-bearing structures or projects with low strength requirements, S235JRH is the most cost-effective choice.

2. Excellent Weldability
Carbon content ≤ 0.17%, carbon equivalent ≤ 0.35%, far lower than S355 grade steel:

Suitable for all conventional welding processes
Thin-walled specifications require no preheating
Extremely low risk of heat-affected zone cracking
High on-site construction efficiency

3. Good Formability
As a cold-forming product, S235JRH maintains good plasticity and is easy to perform:

Cutting, drilling, stamping
Cold bending, flattening
Flanging, necking

4. CE Certification and Compliance
S235JRH square hollow profiles are available with the following certifications:

●EN 10204 Type 2.2 test report (standard supply)
●EN 10204 Type 3.1 certificate (on demand)
●CE marking (compliant with CPR regulations)
●UKCA marking (UK market)

Applications:

S235JRH Square hollow profiles are suitable for engineering scenarios with medium strength requirements and a focus on economy:

1. Construction Industry: Industrial plant support, warehouse frames, scaffolding, formwork support
2. Mechanical Engineering: Agricultural machinery, truck and trailer manufacturing, cranes, construction machinery
3. Vehicle Manufacturing: Truck body frames, trailer structures, bus manufacturing
4. Renewable Energy: Solar parking sheds, photovoltaic tracking brackets
5. General Steel Structures: Stairs, railings, platform walkways, fences, billboards

Procurement and Application Recommendations:

① Confirm Impact Toughness Requirements
If the project is located in a cold region or involves winter construction, the room temperature impact resistance of S235JRH may be insufficient; S235J2H (-20°C impact guarantee) should be selected.

② Verify Material Certificates
Require suppliers to provide EN 10204 certificates during procurement to verify chemical composition and mechanical property data.

③ Key Points for On-site Inspection: Upon arrival, randomly sample and inspect the side length and wall thickness according to EN 10219-2 tolerance standards:
Side length deviation: ±1% (minimum ±0.5mm)
Wall thickness deviation: ±10% when t≤5mm, ±0.5mm when t>5mm

④ Corrosion Protection Treatment

S235JRH is carbon steel and is not inherently corrosion-resistant. S235JRH is suitable for hot-dip galvanizing (galvanizing category A). When used outdoors or in humid environments, hot-dip galvanizing or coating protection is required.
