Packing & Delivery

ASTM A992 is a primary standard for wide-flange  H-beams in the U.S. construction industry, which is widely used because of its excellent mechanical properties and weldability. It has excellent strength and ductility, and its performance is better than traditional steel grades such as A36 and A572 - 50. 

A992 H steel adopts the W - W-series model naming rule for American - standard wide - flange H - beams, where "W" represents wide flange, the first number refers to the nominal section height in inches, and the latter number stands for the theoretical weight in pounds per foot. Besides the W8x15 you previously learned about, many common models are covering multiple size ranges to meet different load - bearing and structural needs. Here are typical models sorted by nominal section height:

In addition, A992 H - steel can also be matched with HEA, HEB, HEM series sizes specified in DIN standards for production according to project needs (e.g., HEB100, HEB600, etc.), and non - standard models can be customized if required.

1.W8 series (small-sized, suitable for light-load structures) 
This series has a nominal section height of 8 inches and is often used in auxiliary components and small - load - bearing structures. In addition to W8x15, there are models like W8x13 (lighter than W8x15) and W8x18 (heavier, with higher load-bearing capacity).
2.W21 series (medium-sized, for medium-load building frames) 
With a nominal height of 21 inches, it is a common choice for secondary beams of industrial plants and frames of small commercial buildings. A typical model is W21x44, with a section size of approximately 524.76mm×165.1mm, a web thickness of 8.89mm, a flange thickness of 11.43mm, and a weight of 65.79kg/m.

W24 series (medium - large sized, widely used in main building structures) and W27 series (large - sized, for heavy - load structures)
This is a highly versatile series with multiple models for different load requirements. Partial representative models are as follows:

Model	Section Size (mm)	Weight (kg/m)
W24x55	598.68×177.93×10.03×12.83	82.28
W24x104	611.12×323.85×12.7×19.05	155.31
W24x162	635×329.06×17.91×30.99	241.96
W27x84	678.43×252.98×11.68×16.26	125.43
W27x129	701.8×254.25×15.49×27.94	191.71
W27x217	722.12×358.52×21.08×38.1	322.97
