Materials and performance
Core material: mainly A572GR50 or A992 steel3, yield strength ≥345MPa, tensile strength ≥450MPa; elongation ≥18%, meet ASTM A6/A6M toughness requirements.
Process characteristics
Weldability: suitable for arc welding and gas shielded welding, preheating to 120-150℃ to reduce cold crack wind.
Cold bending processing: cold bending forming with radius ≥2 times thickness is allowed.
Engineering application of w12x14 w12x16 w12x19 wide flange beam
Building structure
Light frame: W12x14 steel wide flange beam is used for secondary beams of light factory floor.
Load-bearing system: W12x16/W12x19 is used as main beam or column to support industrial factory with a span of 20-30m.
Bridges and Transportation
W12x19 metal beam structure is used for small and medium span bridge beams to carry dynamic loads (such as vehicle traffic).
W12x163 h section column is preferred in subway platform ceiling support structure.
Machinery Manufacturing
Crane track beam (W12x19 w flange beam), conveyor bracket (W12x14 w shape beam).
Heavy equipment base (needs to be used with W12x16 h beam wide flange to enhance torsion resistance).
Selection suggestions
| Scenario | Recommended models | Advantages |
|---|---|---|
| Light warehouse/commercial building | W12x14 h beam wide flange | Light weight, reducing foundation costs |
| Medium-sized factory/multi-storey garage | W12x16 h beam wide flange | High cost performance and balanced load |
| Heavy Industrial/Long Span Bridges | W12x19 wf steel beam | High load tolerance and strong fatigue resistance |
