H-beams are currently widely used in various construction industries, serving as load-bearing structures and reinforcement, among numerous applications. However, H-beams also have their inherent defects. Today, let's discuss the product defects of H-beams, the little all-rounder in the construction industry.

Inclusions: This refers to the distinct layered structure on the cross-section of H-shaped steel, characterized by gray or white impurities, which are usually refractory materials or slag. The primary cause of this phenomenon is the presence of foreign matter in the molten steel during the steelmaking process, or the entry of refractory materials and slag into the molten steel during the casting process. Inclusions significantly compromise the integrity of H-shaped steel, weaken its stiffness and strength, and may even lead to cracking during use. This severe defect in the use of H-shaped steel is unforgivable.

Lamination: Lamination refers to the linear defect pattern on the cross-section of H-shaped steel.

Scabbing: Scabbing refers to the scale-like defects that appear on the surface of steel.

Cracks: Cracks can primarily be categorized into two types: one is the longitudinal cracks found in the waist area, and the other is the transverse cracks located at the leg ends.
