Commonly, fall arrest systems are made of stainless steel and aluminum. Since lifelines are long-life systems, often located in outdoor environments, the most suitable material is stainless steel. However, there are cases where lifeline anchors are manufactured from materials with lower corrosion resistance due to cost reasons. Lifeline systems should have elements that provide line tension and elements that will absorb the energy that will occur in the event of a fall. When evaluating the price between systems, it is necessary to consider the material of the products. There is a significant cost difference between stainless steel material and others.
