EN 10056-1 Standard: Geometric parameters for hot-rolled equal and unequal angles
The EN 10056-1 standard establishes mandatory requirements for the nominal dimensions of hot-rolled angles manufactured from structural steel grades. Using these specifications ensures the accuracy of structural steel design and compliance of products with international engineering standards.
It is important to note that this standard does not apply to:
- Profiles manufactured from square billets.
- Angles produced from corrosion-resistant (stainless) steels.
To determine the limit deviations for the shape and mass of rolled products, EV Group China specialists recommend using the provisions of the EN 10056-2 standard.
EN 10056-2 Standard: Tolerances on shape, dimensions, and mass for structural angles
The EN 10056-2 technical specifications define the permissible deviations for hot-rolled angles regulated by the first part of the standard. Compliance with these tolerances is critical for ensuring the load-bearing capacity of building frames and engineering structures.
Key aspects of applying the standard:
- Regulation of deviations for leg width, wall thickness, and opening angle.
- Limitations on curvature and twisting of the profile.
- The standard does not cover stainless steel products.
EV Group China experts emphasize that these requirements are fundamental for the production and quality control of rolled metal supplied for critical construction projects.
