General Information

Overview
EN 10058:2018 is a comprehensive European standard developed by CEN that defines the nominal dimensions and tolerances for hot rolled flat steel bars and steel wide flats used for general purposes. This standard ensures uniformity and quality in the manufacturing and supply of these steel products by specifying clear guidelines for their dimensions, shape, and permissible deviations. It applies to a wide range of flat steel bars and wide flats but excludes specialized products such as spring leaves, which fall under a different standard (EN 10092-1).
Updated in 2018, EN 10058 replaces the previous version from 2003, incorporating additional widths for flat bars and introducing wide flats with specified thickness variation limits, reflecting industry advances and practical manufacturing requirements.
Key Topics
Dimensions and Designation
- Nominal dimensions: Width, thickness, and length are standardized, with preferred sizes detailed in the document.
- Range: Includes widths from 10 mm up to wide flats of 200 mm, and thicknesses from 4 to 80 mm.
- Designation format: Product type (“flat bar” or “wide flat”), standard number (EN 10058), dimensions in mm (width x thickness x length), length type (M, F, or E), and steel grade.
Tolerances on Dimensions and Shape
- Thickness and Width: Specific limit deviations depending on the nominal dimensions, e.g., ±0.75 mm for widths between 10-40 mm.
- Length: Tolerance varies by length type - Manufacturing length (M), Fixed length (F), and Exact length (E).
- Straightness: Defined maximum allowable deviation relative to the bar length, ensuring reliable flatness and usability.
- Out-of-squareness: Maximum angle deviation allowed between width and thickness planes to maintain geometric accuracy.
- Thickness Variation (Wide Flats): Maximum permissible thickness variation across the width is 0.5 mm for widths greater than 150 mm.
Measurement Methods
- Measurement points for width and thickness must be at least 100 mm from bar ends to avoid inaccuracies from cold shearing.
- Length is measured as the longest point on the bar.
- Straightness is evaluated over the full length.
- Thickness variation across wide flats is measured perpendicular to the length axis, with specific exclusion zones near edges and ends.
Applications
EN 10058:2018 flat steel bars and wide flats are widely used in:
- General steel fabrication - construction frameworks, machinery parts, and structural components.
- Manufacturing industries requiring standardized steel flat products with reliable mechanical performance.
- Metalworking and tooling applications where dimensional precision and shape tolerance are critical.
- Automotive, engineering, and infrastructure sectors that require hot rolled steel with guaranteed compliance to European dimensional standards.
Adherence to this standard ensures product interchangeability, optimized manufacturing processes, and improved quality control.
Related Standards
- EN 10092-1: Specifies dimensions and tolerances for hot rolled spring steel flat bars (spring leaves), not covered by EN 10058.
- EN 10079: Provides definitions for steel products, ensuring common terminology and classification.
- EN 10088-1: Lists stainless steel grades relevant for mass calculations and steel selection when stainless steel variants are used.
Summary
EN 10058:2018 delivers critical guidelines for the dimensions and tolerances of hot rolled steel flat bars and wide flats, supporting consistent production and quality assurance across European markets. This standard is key for suppliers, fabricators, engineers, and quality inspectors involved with hot rolled flat steel products, providing clear measurement criteria and tolerance limits essential for reliable and standardized steel components in diverse industries.
