SIST EN 10279:2000

Overview

SIST EN 10279:2000 is a European Standard developed by CEN that defines the tolerances on shape, dimensions, and mass of hot rolled steel channels. These channels may have either tapered flanges or parallel flanges, and the standard ensures consistent quality and dimensional accuracy in their production. It specifically applies to hot-rolled steel channels excluding those manufactured from stainless steel. The standard aims to provide clear guidance on permissible variations during manufacturing to guarantee reliable performance in construction and engineering applications.

Key Topics

• Scope of Application
  SIST EN 10279:2000 covers hot rolled steel channels that are commonly used as structural elements. It standardizes expectations regarding their geometric and mass characteristics but excludes stainless steel variants.

• Dimension and Shape Tolerances
  The standard specifies allowable ranges for dimensions such as flange width, web height, and thickness. It also details permissible deviations in shape, ensuring channels maintain proper alignment and symmetry essential for structural integrity.

• Mass Tolerances
  The document defines acceptable variances in mass per unit length. Accurate mass tolerances are critical for cost estimation, load calculations, and transportation considerations.

• Channel Flange Types
  The tolerance requirements are applicable for channels with both tapered and parallel flanges, providing flexibility for different design needs while maintaining quality.

Applications

• Structural Engineering
  Hot rolled steel channels conforming to SIST EN 10279:2000 are extensively used in frameworks for buildings, bridges, and other infrastructures due to their strength and uniformity.

• Construction Industry
  The standardized tolerances ensure that steel channels fit precisely in prefabricated assemblies, reducing installation errors and improving project timelines.

• Manufacturing and Fabrication
  Steel processors and fabricators rely on EN 10279 to control quality during rolling and shaping processes. Maintaining dimensional and mass tolerances minimizes waste and material inconsistencies.

• Quality Assurance and Compliance
  Manufacturers offering hot rolled steel channels implement EN 10279 to demonstrate compliance with European market regulations, facilitating trade and customer confidence.
