Hot rolled steel equal flange tees with radiused root and toes - Dimensions and tolerances on shape and dimensions

This European standard specifies requirements for the nominal dimensions and the tolerances on dimensions, shape and mass of hot-rolled steel equal flange tees with radiused root and toes. These requirements do not apply to equal flange tees produced from stainless steel.

Diese Europäische Norm gilt für die Anforderungen an die Nennmaße sowie an die Grenzabmaße, Formtoleranzen und Grenzabweichungen der Masse von warmgewalztem gleichschenkligem T-Stahl mit gerundeten Kanten und Übergängen. Die Anforderungen gelten nicht für warmgewalzten gleichschenkligen T-Stahl aus nichtrostenden Stählen.

Overview

EN 10055:1995 is a European (CEN) standard that defines the nominal dimensions and tolerances for hot-rolled steel equal-flange tees with radiused root and toes. The standard sets out requirements for dimensions, shape and mass for these specific steel profiles produced by hot-rolling processes. It applies to carbon and alloy hot-rolled tees but excludes stainless steel products.

Keywords: EN 10055, hot rolled steel, equal flange tees, radiused root, tolerances, dimensions, steel profiles.

Key topics and requirements

The standard focuses on measurable geometric and production-related parameters for equal-flange tees:

• Nominal dimensions: definition of standard sizes and sectional dimensions for equal-flange tees.
• Dimensional tolerances: permitted deviations from nominal values for width, thickness and other key dimensions.
• Shape tolerances: allowable variation in straightness, squareness, camber and other shape characteristics.
• Mass tolerances: acceptable variation in mass per unit length used for weight and structural calculations.
• Profile features: specification of radiused root and toes as characteristic geometric elements of the tee section.
• Scope limitations: applies only to hot-rolled equal flange tees; stainless steel tees are excluded.

Note: EN 10055 establishes requirements and terminology for manufacturers, purchasers and inspectors but does not prescribe material grades or mechanical property requirements beyond shape and dimensional control.

Applications and who uses this standard

EN 10055 is practical for professionals and organizations involved with steel profile production, procurement and structural design:

• Steel manufacturers and rolling mills - to produce tees that meet common European dimensional and shape tolerances.
• Structural engineers and detailers - to select sections with known dimensional and mass tolerances for design and calculation.
• Fabricators and welders - to assess fit-up and fabrication allowances based on permitted shape and dimensional deviations.
• Quality control and inspection teams - to verify conformance of delivered tees against agreed tolerances.
• Purchasers and specifications writers - to reference a harmonized European standard in procurement documents.

Typical uses include structural framing, connections, bracing elements and other applications where equal-flange tee profiles are required.

Related standards

EN 10055 is part of the family of European steel profile standards. Users often consult other EN standards covering hot-rolled sections, material grades, mechanical properties and testing procedures when specifying or verifying complete structural components. For procurement and design, reference to EN 10055 ensures compatibility and interchangeability of hot-rolled equal-flange tees across suppliers.
