S355K2 Hot Rolled Material H Beam
The "S" in S355K2 H-profile stands for "structural steel", while the "355" indicates that it has a minimum yield strength of 355 MPa (megapascals). The "K2" indicates that the steel has been impact tested at -20°C with a minimum longitudinal Charpy V-notch impact energy of 40 joules, making it suitable for use in colder environments.
GNEE's S355K2 hot rolled steel is typically supplied in the normalized or controlled rolled condition, which enhances its mechanical properties and ensures uniformity.

GNEE produces S355K2 H-beams in a wide range of profiles, each designed for a specific structural use:
HEA (Light Wide Flange Beam): Lightweight, with parallel flanges, in accordance with DIN 1025-3.
HEB (Standard Wide Flange Beam): Stronger, heavier, in accordance with DIN 1025-2.
HEM (Heavy Wide Flange Beam): Thickest, strongest, for heavy-duty applications.
Typical Dimensions
Height (depth): 100 mm to 1000 mm
Flange width: 100 mm to 400 mm
Web thickness: 5 mm to 21 mm
Flange thickness: 8 mm to 36 mm
Length: Standard lengths range from 6 m to 12 m, custom lengths (e.g. 14 m or 18 m) are available on request.
