EN 10219 S235JRH / S275JRH / S355JRH SHS – Main Applications
Manufactured to the EN 10219 standard, S235JRH, S275JRH and S355JRH square hollow sections (SHS) feature stable dimensional accuracy, reliable weldability and balanced structural performance. These versatile structural steel profiles are widely adopted across civil construction, industrial engineering, infrastructure and mechanical fabrication projects worldwide.
Building & Commercial Construction
Ideal for core structural frameworks of residential and commercial buildings, multi-storey steel structures and prefabricated building systems. The consistent mechanical properties make these SHS sections a dependable choice for general building framing and load-bearing structures.
Industrial Facilities
Commonly used for factory main frames, workshop steel structures, warehouse skeletons and logistics facility frameworks. Suitable for both light and medium heavy-duty industrial buildings, delivering outstanding structural stability for long-term service.
Public & Transportation Infrastructure
Widely applied in bridge auxiliary components, highway and railway support structures, tunnel engineering and municipal public infrastructure. The excellent toughness and impact resistance adapt to complex outdoor and underground construction environments.
Mechanical & Equipment Fabrication
Perfect for manufacturing machine frames, equipment support bases, structural platforms, mounting brackets and conveyor system structures. The uniform section size simplifies machining, welding and assembly processes for mechanical engineering projects.
New Energy & Power Engineering
A preferred material for solar panel mounting frames, wind power auxiliary support structures, power plant steel frameworks and substation structural components, meeting the durable and weather-resistant requirements of new energy projects.
Agricultural & Storage Structures
Extensively used for agricultural greenhouses, farm shelters, storage sheds and grain storage facility frames. Cost-effective and adaptable for lightweight structural applications in agricultural and warehousing scenarios.
Architectural & Exterior Decoration
Applied in architectural modeling structures, building facade support systems, outdoor landscape steel structures and modern decorative steel frameworks, balancing structural strength and neat appearance for architectural engineering projects.

1. What is the difference between S235JRH, S275JRH, and S355JRH?
These three grades differ in strength and application scenarios for EN 10219 SHS:
S235JRH: Economical mild steel for light structural applications.
S275JRH: Medium-strength steel for general structural projects.
S355JRH: High-strength steel, the most popular grade for heavy-duty construction.
Higher steel grades feature higher yield strength and better load-bearing capacity.
2. Can you customize size and length?
Yes, full customization and secondary processing are available for EN 10219 SHS.
Custom Specifications
Size: 20×20mm – 500×500mm (custom larger sizes available)
Wall thickness: 1.5mm – 20mm+
Length: Standard 6/9/12m, custom cut-to-size lengths
We also provide cutting, beveling, drilling, oiling, priming and hot-dip galvanizing services.
3. What is the difference between EN 10219 and EN 10210?
The two standards apply to different production techniques and project requirements:
EN 10219 (Cold-formed): Cost-effective welded hollow sections for general construction and standard load-bearing structures.
EN 10210 (Hot-finished): High-performance sections with superior toughness and impact resistance, for critical heavy-duty engineering projects.
4. What certificates can you provide?
We offer complete certified documents for global engineering and customs clearance:
- EN 10204 3.1 MTC/MTR
- Chemical & mechanical test reports
- CE Certificate (EU market)
- ISO 9001 Quality Certificate
All products are fully traceable with strict factory quality control.
5. What are the main applications of EN 10219 SHS?
EN 10219 SHS is widely used in global construction and industrial fields:
- Steel building frames & prefabricated structures
- Workshops, warehouses & logistics buildings
- Municipal infrastructure & bridge auxiliary structures
- Solar mounting & new energy support systems
- Mechanical equipment support frames
