What Material is Used for Engine Guards?

Engine guards are typically made of hard plastic, resin, iron, or aluminum alloy. The benefits of installing an engine guard include: 1. Preventing scratches from gravel and debris: Similar to the function of a protective film (like paint), it acts as a shield, much like a phone case, making it easy to understand. 2. Moisture protection: Rust is one of the major threats to the chassis, especially in rainy southern regions where acidic substances in rainwater can damage the chassis. Therefore, corrosion resistance (or rust prevention) is a crucial feature. 3. Noise reduction: When gravel or foreign objects hit the undercarriage, the noise can be loud. A chassis guard provides some sound insulation. Temperature control is another benefit, as car air conditioning airflow usually moves from bottom to top, and the chassis guard offers some insulation. 4. Reducing undercarriage damage: "Scraping the bottom" often occurs when going over speed bumps, which many drivers have experienced. Poorly designed speed bumps can cause loud, jarring noises, significantly impacting the undercarriage. In such cases, a chassis guard provides effective protection.
