How We Hold Quality
A heat treatment system is located inside our factory to improve the strength and stability of the metal structure. Heating temperature, holding time, and cooling speed are controlled during the process. These steps help maintain the required nodularity rate and impact resistance. Workers check the nodularity rate, tensile strength, and elongation rate of each batch. These inspections help ensure that the covers meet the required heavy-load performance.
