Ground Engaging Tools and Undercarriage are parts that when they are mounted on the equipment, they wear out by reason of the friction with the soil (abrasion). They are responsible for performing the cutting, penetration work and help to protect high-value components, reduce operating costs and ensure that the maximum performance of the equipment is achieved. Because of this issue, Ground Engaging Tools and Undercarriage must pay special attention when there is a need to change them. Regarding the kinds of steel used in the METISA:

ATC Line - High Carbon Steel without Heat Treatment. They are resistant to wear and are intended for light duty applications. Identified by the yellow paint and the low relief marking of the METISA logo, product code and Production Order Number. (OP).

Line AR-1 - Heat-treated Boron Microalloyed Steel. For being temperate integrally, it provides a greater hardness and resistance, therefore, they are recommended for severe services, due to its high resistance to wear and impact. Identified by the red paint and the low relief marking of the METISA logo, product code, Production Order Number (OP) and AR-1;

Cast Line - Medium Chromium and Silicon Alloy Steel with Heat Treatment. They are identified by the yellow color and the embossed marking of the METISA or GETLF logo.
