What is 41kg standard rail used for?
41kg standard rail is used for industrial sidings, underground mining rail systems, workshop overhead crane runways and plant-level transport corridors.

What is the difference between 41kg and 47kg rail?
The 47kg profile is heavier and has a larger cross-section than the 41kg, giving it higher load capacity and greater rigidity for more demanding applications.
