1. H-beam specification table (part)
model | Height (mm) | Flange width (mm) | Web thickness (mm) | Theoretical weight (kg/m) |
HW100×100×6×8 | 100 | 100 | 6 | 17.2 |
HN200×100×5.5×8 | 200 | 100 | 5.5 | 21.7 |
HW300×300×10×15 | 300 | 300 | 10 | 94.5 |
2. Load-bearing calculation method
Formula:
M=f×W/1.05
M: maximum bending moment (kN·m); f: steel yield strength (Q235 is 235N/mm²); W: section modulus (cm³).
Example:
For HW300×300 with a span of 6 meters and a single-point load of 10 tons, it is necessary to calculate whether the deflection exceeds the limit (L/250).
3. Industry application cases
A logistics warehouse: Using HN400×200×8×13, saving 20% of steel and shortening the construction period by 15 days.
Conclusion: The selection of H-shaped steel needs to be combined with mechanical calculation and economy. It is recommended to use BIM software to simulate the construction plan.
Latest News
There is no absolute advantage or disadvantage between hot-dip galvanizing and electrogalvanizing. The key lies in scene adaptation: Choose hot-dip galvanizing: heavy anti-corrosion, long life, high load scene. Choose electrogalvanizing: low cost, high precision, short-term application.
