Product Description

Differences Between European H-beam and Japanese H-beam

1. Basic Standard Systems
European H-beam (HE Series)
Applicable standards: EN 10365, EN 10034, EN 10025, coordinated with European steel structure code Euro code 3 (EN 1993)
Series classification: Divided into HEA (light series), HEB (standard universal series), HEM (heavy series), HL (extra-wide flange series) with clear grading.
Unit of measurement: Fully metric (millimeters).
Japanese H-beam (JIS Series)
Applicable standards: JIS G3192 (dimensions), JIS G3106 (material grades SM steel), designed in compliance with Japan's strict seismic building codes.
Series classification: No HE-type light/heavy grading. Only categorized by height × flange width, including wide-flange, medium-flange and narrow-flange types.
Unit of measurement: Fully metric (millimeters).
2. Model Naming Rules (Most Intuitive Difference)
European HE Nomenclature
Format: HE + number + letter Example: HEB 200
HE = European wide-flange H-beam; B = standard universal type; 200 = nominal section height approx. 200mm.
Web and flange thicknesses are not marked directly on the model and must be obtained from reference tables.
Japanese JIS Nomenclature
Format: H Height × Width × Web thickness × Flange thickness Example: H200×100×5.5×8
Four complete dimensional parameters: H(height) × B(flange width) × t(web thickness) × t(flange thickness).
All dimensions are directly indicated in the model, no lookup table required.
3. Section Geometry & Structural Mechanical Properties (Core Difference)
Flange Profile
European HE sections: Fully parallel flanges with no taper and small fillet radii. Under the same nominal height, flanges are wider with relatively thinner webs. Strength about strong and weak axes is well-balanced, suitable for both axial compression and bending.
Japanese JIS sections: Slightly tapered inner flange surfaces. Overall sections feature thicker webs and narrower, thinner flanges. Material is concentrated in the web, prioritizing strong-axis bending performance while weak-axis stiffness is relatively lower, designed for lightweight material efficiency.
Thickness Ratio & Unit Weight Comparison (same nominal height ≈ 200mm)

Parameter	HEB 200 (European standard)	H200×100×5.5×8 (Japanese standard)	Summary
Height h	200 mm	200 mm	Identical
Flange width b	200 mm	100 mm	European flange is nearly twice as wide
Web thickness t1	9.0 mm	5.5 mm	European web is thicker
Flange thickness t2	15.5 mm	8.0 mm	European flange is thicker
Unit weight	61.3 kg/m	26.6 kg/m	Japanese section is significantly lighter

General Rules
European sections: Thick web + wide & thick flanges, overall heavier weight, large load capacity margin, excellent structural stability.
Japanese sections: Thin web + narrow & thin flanges, lightweight design, steel-saving, optimized for seismic performance.
4. Completely Different Steel Material Systems
European Material Grades (EN 10025)
Main grades: S235JR, S355JR/J0/J2, S460
Yield strengths: 235MPa, 355MPa, 460MPa. Prioritize static load strength, temperature resistance and general structural applications with clear low-temperature impact toughness grading.
Japanese Material Grades (JIS G3106)
Main grades: SM400A/B, SM490A/B, SM520 (structural rolled steel)
Yield strengths: SM400 ≈ 245MPa, SM490 ≈ 325MPa. Specially developed for seismic resistance, with high toughness, low yield ratio and superior seismic energy absorption capacity compared with equivalent-strength European steel.
5. Dimensional Tolerances & Design Philosophy

Dimensional Tolerances

European standard (EN 10034): General and relatively loose tolerances, adapted for long-span industrial buildings, bridges and heavy-duty structures.
Japanese standard (JIS): Tighter and more precise rolling tolerances, suitable for prefabricated steel structures and precision engineering.

Underlying Design Concepts

Eurocode: Larger safety factor, sufficient overload margin, prioritizes permanent static-load structures (industrial plants, bridges, heavy equipment foundations).
Japanese codes: Seismic resilience as top priority, energy dissipation performance, lightweight and steel-efficient construction.

Size Coverage
European: Complete HEA/HEB/HEM range from 100mm to 1000mm, with comprehensive extra-heavy large-size sections.
Japanese: Comprehensive small and medium sizes (H100-H900), far fewer extra-large heavy sections than European standards.
6. Interchangeability & Engineering Replacement

Almost no direct interchangeabilityFlange width, thickness, unit weight, section modulus and bolt hole pitches are all mismatched. Direct substitution is not allowed; structural recalculation is mandatory for any replacement.

Practical selection guidelines

For heavy loads, long spans, heavy columns, bridges and equipment bases: Choose European HEB/HEM sections.
For Japanese-style buildings, seismic high-rises, lightweight factories and Japanese-equipment supporting structures: Choose Japanese JIS H-beams.
