EN 10365 Standard

EN 10365:2017 is a European standard that specifies the nominal dimensions and mass of hot-rolled steel sections, including I-beams, H-beams, and channels. Below is a detailed description of the various types of steel sections covered by this standard:

IPE (I-section Parallel Flange European)

• Description:

European standard parallel flange I-beams with equal flange thickness.

Designed for structural beams with optimized weight-to-strength ratio.

• Key Features:

Flange surfaces are parallel (no taper).

Thinner flanges compared to HEA/HEB.

Common in light-to-medium load-bearing structures (e.g., floor beams).

• Example: IPE 300 (300 mm height, 150 mm flange width).

HEA (Light H-beam):

• Wider flanges than IPE but thinner than HEB.
• Used in general construction (beams & columns).
• Example: HEA 200 (200 mm height, 200 mm flange width).

HEB (Medium H-beam):

• Thicker flanges & web than HEA.
• Higher load capacity, used in heavy construction.
• Example: HEB 300 (300 mm height, 300 mm flange width).

HEM (Heavy H-beam):

• Maximum thickness, used in high-load applications (bridges, industrial plants).
• Example: HEM 400 (400 mm height, 400 mm flange width).

HL (Hybrid Light):

• Optimized for lightweight structures with high strength.

HD (Hybrid Deep):

• Deeper web for increased bending resistance.

HP (Bearing Pile):

• Square-shaped (flange width ≈ height), used for piling & foundations.
• Example: HP 360×370 (360 mm height, 370 mm flange width).

• UPE (Parallel Flange Channels): These channels have parallel flanges, making them suitable for a wide range of structural applications.
• PFC (Parallel Flange Channels): Similar to UPE, these channels are also used in various structural applications.
• UPN (Sloped Flange Channels): These channels have sloped flanges, which can provide better load distribution in certain applications.
• U (Sloped Flange Channels): These are another type of sloped flange channels, used in various structural applications.
• CH (Sloped Flange Channels): These channels are also used in structural applications where sloped flanges are required.

• UB (Universal Beams): These are general-purpose I-beams used in a wide range of structural applications.
• UC (Universal Columns): These are general-purpose columns used in building structures.
• IPN (Sloped Flange I-Sections): These I-beams have sloped flanges, which can provide better load distribution in certain applications.
• J (Sloped Flange I-Sections): These are another type of sloped flange I-beams, used in various structural applications.

These steel sections are widely used in construction and engineering projects due to their strength, versatility, and ease of fabrication. The specific type of section chosen depends on the requirements of the project, such as load-bearing capacity, stability, and ease of installation.
