ISO 4950
ISO 4950:2021 is the latest international standard that classifies hot-rolled steel plates, wide flats, and sections for structural uses, especially in construction and general engineering applications. Developed by the International Organization for Standardization, this standard ensures consistent quality and performance in non-alloy structural steel products. As industries grow more quality-conscious, adherence to ISO 4950 becomes essential for manufacturers and suppliers catering to infrastructure, fabrication, and engineering markets.
At Quality Asia Certification, we support organizations in obtaining ISO 4950:2021 certification, helping them meet global steel quality expectations with compliance and confidence.

What is ISO 4950?
ISO 4950:2021 – Hot-Rolled Steel Plates, Wide Flats, and Sections for Structural Purposes
This ISO standard sets out technical delivery conditions for non-alloy structural steel used in various construction and fabrication applications. It specifies chemical composition, mechanical properties, tolerances, testing methods, and designation systems. The standard is primarily used by steel manufacturers, structural fabricators, and quality control departments to maintain product reliability and ensure regulatory alignment with international steel classifications.
Why is ISO 4950 important?
In an increasingly regulated and competitive industrial environment, compliance with ISO 4950:2021 helps organizations prove their product reliability and structural consistency. It reduces the risk of material failure, improves buyer confidence, and enhances product traceability in global markets.
Whether you're supplying steel for bridges, buildings, or machinery components, ISO 4950 assures your clients that your materials are manufactured to globally recognized benchmarks. Choosing this certification ensures you're aligned with modern structural performance requirements and international procurement standards.
What are the benefits of ISO 4950?
- Defines quality grades (S185, S235, S275, S355) for better product selection and customer communication
- Improves standardization in manufacturing hot-rolled steel products
- Ensures mechanical property reliability for critical load-bearing structures
