The hardness index is an important indicator reflecting the mechanical performance of forged scaffolding couplers, which determines their wear resistance, load-bearing capacity and service life, and is strictly standardized.
Brinell hardness (HB) is the most commonly used index for forged scaffolding couplers, with a standard range of 120-180 HB. This range balances the couplers’ strength and toughness, preventing brittleness from excessive hardness or deformation from insufficient hardness.
Rockwell hardness (HRB) is another common measurement, with a standard range of 60-80 HRB, which corresponds to the Brinell hardness range and ensures the couplers can withstand repeated assembly, disassembly and heavy loads.
These hardness indexes comply with international and national standards such as EN74 and GB/T 15831-2023, and are affected by the forging and heat treatment processes to ensure adaptability to construction scenarios.
