What are the materials of engine guards? What are the pros and cons of each?

[GenesisAnn]

There are four types of materials for engine guards: steel plate, reinforced resin, plastic, and aluminum alloy. Below are the pros and cons of each material: 1. Steel plate is currently the most popular among car owners due to its low cost and hard texture, providing the best protection for the engine. However, it is heavy, affects the chassis balance, and may interfere with the engine's safety drop in severe accidents. 2. Reinforced resin is much lighter than steel plate and can easily handle minor scratches and erosion from mud and sand. However, its overall strength is inferior to steel plate. 3. Plastic guards are low-cost and lightweight, but they are very thin and have poor strength. Even minor scratches can cause them to break, making them the lowest-grade product. Many low-end cars come with plastic guards as standard. 4. Aluminum alloy guards are lightweight, high-strength, and aesthetically pleasing, but they are also more expensive.
