Premium Material Construction and Durability
Half marathon medals distinguish themselves through their exceptional material composition and construction techniques. The primary material, typically a zinc alloy or brass base, undergoes rigorous quality control to ensure optimal weight distribution and structural integrity. This foundation is enhanced through a multi-layer plating process that not only provides the desired finish but also creates a protective barrier against environmental factors. The plating process includes anti-tarnish treatments that maintain the medal's luster even after years of display or handling. The die-casting process employs high-pressure techniques that capture intricate design details while eliminating common defects like air pockets or surface inconsistencies.
