structure steel h profile W27*178 A36 A992
Specifications of W27×178 material h beam
W: Wide flange H-beam steel.
27: Nominal height of the steel, in inches, about 686 mm.
178: Weight per foot, in pounds per foot (lb/ft), about 265 kg/m (weight per meter).
Height: about 686 mm (27 inches).
Flange width: about 356 mm (14 inches).
Web thickness: about 17.3 mm (0.68 inches).
Flange thickness: about 30.2 mm (1.19 inches).
Cross-sectional area: about 338 cm² (52.3 in²).
W27×178 H-beam can be produced with A36 or A992 materials. Both materials meet ASTM (American Society for Testing and Materials) standards, but their performance and uses are different.

Features of W27×178 material h beam
Sectional characteristics: W27×178 steel beam h is a wide flange H-beam with optimized cross-sectional area distribution and a high strength-to-weight ratio. The flange is wide and the web is thin, which is suitable for bearing large bending moments and shear forces.
Bending capacity: Since the flange and web are arranged at right angles, W27×178 has excellent bending resistance in all directions.
Weight: About 265 kg per meter, it is a heavier model in the W27 series and is suitable for scenes requiring high load-bearing capacity.
A36 A992 H Steel Profile Application Comparison
A36 W27×178 h profile steel: suitable for general civil and industrial building structures, such as factories and warehouses; used in scenes where strength requirements are not particularly high, such as bridges and mechanical equipment frames.
A992 W27×178 h beam profile: widely used in large-span buildings (such as high-rise buildings and gymnasiums); suitable for structures that require high strength and durability, such as bridges, offshore platforms, and heavy equipment supports.
Performs better in earthquake-prone areas or high-temperature working environments.
