Which Material is Better for Engine Guards?

[DeReese]

Engine guards come in the following materials: 1. Hard plastic/resin guards: These are relatively inexpensive and simple to manufacture. They can easily handle erosion from mud and sand, as well as minor scratches and scrapes to the undercarriage. However, their overall strength is inferior to steel plates. While they have some toughness, they can easily shatter under slightly severe impacts, which ironically helps the engine to sink smoothly in the event of a serious accident. It's worth noting that this material is prone to breaking, especially in winter, and once damaged, it cannot be repaired, failing to provide long-term protection. 2. Steel plate guards: The advantage of steel plate material is its strong impact resistance and low cost. In severe accidents, steel plates tend to deform rather than break, but this can interfere with the engine's safe sinking during a collision and may even cause the engine to be damaged first due to the deformation of the steel plate. Therefore, it has both advantages and disadvantages. 3. Aluminum alloy (titanium alloy) guards: The advantage of aluminum alloy (titanium alloy) guards is that they are lighter than steel guards. However, they are more expensive, lack elasticity, can hinder engine sinking, are prone to resonance, and have lower material strength. 4. Alloy plastic-steel guards: The characteristics of alloy plastic-steel material are light weight, high toughness, and strong pressure resistance. They also exhibit excellent physical properties such as rigidity, elasticity, corrosion resistance, and aging resistance.
