BS EN 10219:Cold Formed Welded Structural Hollow Sections of Non-Alloy And Fine Grain Steels

Cold formed welded structural hollow sections conforming to BS EN 10219 are widely used in various applications due to their versatility and advantageous properties. One significant application is in the construction industry, where these sections are utilized as structural members, columns, and beams in buildings, bridges, and other large-scale projects. Their high strength-to-weight ratio and resistance to corrosion make them suitable for load-bearing components exposed to harsh environments.

In addition to construction, these hollow sections find applications in the automotive industry for vehicle frames, chassis components, and exhaust systems due to their durability and weight reduction potential. They are also employed in the manufacturing of machinery, equipment, and wind turbines, where their structural integrity and resistance to fatigue are crucial. Moreover, the hollow sections can be used in furniture, handrails, and decorative elements owing to their aesthetic appeal and formability.

Purchasing Recommendations: When selecting cold formed welded structural hollow sections according to BS EN 10219,consider the following factors:

1. Grade Selection: Choose the appropriate steel grade based on the required mechanical properties and intended application. Non-alloy steels offer good weldability and formability, while fine grain steels provide enhanced strength and toughness.

2. Quality Certification: Ensure that the hollow sections are accompanied by quality certifications and test reports, verifying compliance with BS EN 10219 standards. This documentation guarantees that the products meet specified chemical composition, mechanical properties, and dimensional tolerances.

3. Supplier Reputation: Source hollow sections from reputable suppliers with a proven track record of supplying quality products consistent with BS EN 10219. Request references, client testimonials, and product samples to assess their reliability and performance.

4. Cost-Effectiveness: Compare prices from multiple suppliers while considering factors like transportation, handling, and order quantities. Strike a balance between cost-effectiveness and quality to ensure value for money without compromising on safety and performance.

5. Technical Support: Inquire about the supplier's technical support capabilities, including assistance with product selection, design recommendations, and compliance issues. A responsive and knowledgeable technical support team can help streamline the procurement and application processes.

6. Delivery and Logistics: Discuss delivery lead times, transportation options, and packaging methods with suppliers to ensure timely and secure receipt of the hollow sections. Plan for any additional logistics requirements, such as storage or special handling, to maintain product quality and integrity.

By considering these factors, buyers can make informed purchasing decisions, ensuring that the cold formed welded structural hollow sections meet BS EN 10219 standards, satisfy project requirements, and offer optimal performance in various applications.

Manufacturing Process: Cold formed welded structural hollow sections are produced through a combination of cold forming and welding techniques. The steel strips or plates are shaped into tubular sections at room temperature without heating, followed by electric resistance welding or high-frequency induction welding to join the edges. This process ensures consistent quality and dimensional accuracy while maintaining favorable mechanical properties.

Dimensional Tolerances: BS EN 10219 specifies tolerance limits for dimensions such as outer diameter, wall thickness, length, and ovality. These tolerances vary depending on the grade and dimensions of the hollow sections, ensuring proper fitment and structural integrity in applications. Manufacturers must adhere to these tolerances to comply with the standard and maintain quality control.
