Product Overview

EN 10219 426×8.5 S275J0H is a high-quality cold-formed welded circular hollow section (CHS), designed in full compliance with European EN 10219 standards. The grade S275J0H features reliable medium structural strength, good weldability, and stable impact toughness at 0°C - the "J0" suffix indicates the material meets impact test requirements at 0°C, while "H" denotes the hollow section quality grade, specifically optimized for structural load-bearing scenarios suitable for medium-strength applications.

Our 426×8.5 mm hollow section is manufactured with strict quality control, ensuring uniform wall thickness, precise dimensions, and stable mechanical properties. It is an ideal choice for medium-load structural applications, suitable for both onshore and general industrial projects that require compliance with European standards, balancing performance and cost-effectiveness.

Raw Material: Hot-rolled steel coils complying with EN 10025 standard (non-alloy structural steel)

Processing Steps: Uncoiling → Leveling → Cutting → Forming → Welding → Deburring → Straightening → Sizing → Inspection → Surface Treatment

Surface Treatment:

Standard: Anti-rust oil coating, black oxide finish (free of scale)

Optional: Shot blasting (Sa2.5 grade), zinc plating, epoxy coating, painting (customizable per customer request)

Optional Processing: Cutting to length, drilling, bending, welding fabrication, and custom end treatments

Quality & Inspection

All products fully comply with EN 10219-1/EN 10219-2 standards, with strict quality control throughout the production process:

Visual Inspection: Check surface quality, weld appearance, and dimensional consistency

Dimensional Inspection: Verify outside diameter, wall thickness, length, and roundness

Mechanical Tests: Tensile test, elongation test, Charpy V-notch impact test (0°C), hardness test

Weld Inspection: Ultrasonic Testing (UT) for weld integrity (100% inspection optional), flattening test, bending test

Certificates: Mill Test Report (MTR) per EN 10204 3.1/B, material traceability, and third-party inspection report (optional, e.g., TÜV, BV)

Typical Applications

Suitable for European standard projects and medium-strength structural applications requiring reliability and cost-effectiveness:

Building steel structures (columns, beams, trusses, frameworks for small and medium-sized buildings)

Bridge components (railings, auxiliary supports, non-main load-bearing parts)

Machinery and equipment (light-duty chassis, frames, supports)

Construction accessories (stairs, railings, handrails)

Transmission towers, light-duty power engineering structures

Industrial pipelines, ventilation systems, and general structural supports

Onshore engineering, prefabricated steel structures, non-load-bearing components
