What is EN 10058:2003+A1:2013?

EN 10058:2003+A1:2013 is a technical standard that specifies the general requirements for hot-rolled equal and unequal steel angles for structural purposes. This standard is applicable to angles of width from 20 mm to 250 mm, thicknesses from 3 mm to 40 mm, and steel grades with specified minimum yield strengths between 185 MPa and 450 MPa.

The Purpose and Application

The purpose of EN 10058:2003+A1:2013 is to ensure that steel angles meet the required mechanical properties, tolerances, and dimensions necessary for their structural use. These angles are commonly used in construction, engineering, and manufacturing applications. They provide stability, support, and load-bearing capabilities in various structures such as buildings, bridges, and machinery.

Detailed Specifications

This standard defines the tolerances on dimensions, shape, and mass of hot-rolled equal and unequal steel angles. It specifies the minimum requirements for chemical composition, mechanical properties, and surface quality. The dimensional tolerances outlined in this standard help ensure the correct fit and alignment of the angles during fabrication and construction processes. The chemical composition requirements guarantee the desired strength and corrosion resistance of the steel, while the specified mechanical properties ensure structural integrity and load-bearing capacity.

Compliance and Certification

Manufacturers and suppliers of hot-rolled steel angles must comply with the provisions of EN 10058:2003+A1:2013 to be able to certify their products. Compliance with this standard ensures that the angles meet the necessary requirements for structural use. Certification provides assurance to end-users, designers, and regulatory bodies that the angles have been manufactured according to established standards and are suitable for their intended applications.
