W27x178 A36 w shape structural steel
A36 h type steel beam material characteristics
Material standard
A36 is an American standard carbon structural steel, which complies with ASTM A6 standard. Its chemical composition is mainly iron, with carbon content ≤0.25% and manganese content 0.8-1.2%.
Mechanical properties
It has good strength (yield strength ≥250MPa, tensile strength 400-550MPa) and plasticity (elongation ≥20%), suitable for welding and cold processing.
Performance advantages
Weldability : The welding process has strong adaptability, and heat input needs to be controlled to avoid embrittlement.
Corrosion resistance : Corrosion-resistant under normal environment, and additional anti-corrosion treatment is required in humid or acidic and alkaline environment.
W27x178 h beam wide flange parameters
W27 : Section height 27 inches (about 686mm); x178 : Unit length weight 178 pounds/foot (about 264kg/m).
Typical cross-sectional dimensions
| parameter | Numerical value (estimated) |
|---|---|
| Leg width | ~356mm (14 inches) |
| Web thickness | ~18.4mm |
| Flange thickness | ~30.2mm |
| Cross-sectional area | ~227cm² |
Application of A36 W27x178 w wide flange beam
Architectural structure: used for high-rise building frames and industrial plant support beams to meet large-span load-bearing requirements.
Bridge engineering: suitable for medium-span bridge main beams and bridge deck support structures.
Machinery manufacturing: high-load components such as crane rails and heavy equipment bases.
GNEE manufacturing and processing requirements
Production process
Hot rolling forming is the main method, and the rolling temperature and cooling rate are controlled to ensure mechanical properties.
The surface can be galvanized, painted, and other anti-corrosion treatments to extend the service life.
Quality verification
GNEE can provide a material certificate (MTC), including chemical composition, mechanical properties, and impact toughness test data.
