Hot rolled beams HEB Hot rolled beams HEB700
HEB700 h-shaped iron beam basic dimensions
Height (h): 700 mm
Width (b): 300 mm
Web thickness (waist thickness): 17 mm (some standards are 14 mm)
Flange thickness (leg thickness): 32 mm
Theoretical weight: about 168.6 kg/m1, some specification tables show 241 kg/m (note that there may be differences in different standards or production batches).
Sectional characteristics
The cross-section is symmetrical H-shaped, with a large moment of inertia and excellent lateral bending resistance, suitable for large-span structures.
HEB700 h-shaped beam common materials
S355JR/J0/J2 h beam material: European standard low-carbon steel, with high yield strength (420-490MPa), good weldability and corrosion resistance, suitable for complex stress environments.
S275JR/S235JR h beam steel structure material: economical steel, suitable for conventional load-bearing scenarios.
HEB700 structural steel h beam application areas
Construction engineering: large industrial plant beams, high-rise building frames, earthquake-resistant structures.
Infrastructure: bridge supports, highway guardrails, ship frames.
Machinery manufacturing: heavy equipment frames, mine supports, large machinery bases.
HEB700 structural h beam implementation standards
European standards: EN10025-2 (chemical composition), EN10034 (tolerance), EN10056-2 (dimensional inspection).
American standard/Japanese standard: ASTM A36, JIS G3101 (customizable for some companies).
Quality control: ensure material consistency through metallographic analysis, mechanical property testing and non-destructive testing (ultrasonic flaw detection).
HEB700 h section beam advantages and characteristics
Structural advantages: large width-to-thickness ratio, strong stability, and can reduce the need for additional reinforcement.
Convenience of construction: regular cross-sections are easy to cut and weld, shortening the construction period.
Economical: Save 30%-40% of steel compared to traditional I-beams, reducing overall costs.
