W40×149 -211 W-shaped steel, ASTM A992 hot-rolled W beam
The W40 series wide-flange beams belong to the American standard heavy-duty hot-rolled W-shaped steel. They have a large cross-sectional height and excellent bending resistance, and are commonly used as deep beams in highway bridges. They are often used as the main beams of bridges to bear the bridge deck loads, suitable for large-span structures, and comply with the ASTM A992 standard. They are widely used in the highway engineering in the central and western regions of the United States and can also be used in large factories, heavy-load frames, and other projects with high requirements for vertical bearing capacity.
