1. Chemical corrosion resistance: Fiber reinforced polyester materials have good corrosion resistance properties, such as acid, dilute alkali, salt, organic solvents, and seawater, while metal materials are not resistant to acid and seawater.

2. Lightweight and high-strength: Specific strength and modulus are one of the indicators for measuring the bearing capacity of materials. The specific modulus of fiber-reinforced polyester material is comparable to steel, but its specific strength can reach four times that of steel.

3. Good electrical performance: This material not only has excellent electrical insulation, but also maintains good dielectric properties at high frequencies, is not affected by electromagnetic waves, and does not reflect electromagnetic waves. These properties far exceed what metal materials can compare to.

4. Gap sensitivity: When the component is overloaded and a small amount of fibers break, the load quickly distributes on the undamaged fibers, thereby achieving mechanical balance again. This is incomparable to metal components.

5. Good practicality: The tensile strength of fiber-reinforced polyester materials is slightly better than that of steel. Steel and most metal materials have a tensile strength of 40% -50%, while fiber-reinforced composite materials generally have a tensile strength higher than this value, reaching 70% -80%.

6. Low thermal conductivity and small expansion coefficient: When there is a temperature difference, the thermal stress generated is much smaller than that of metals.

7. Flame retardant, smoke-free, and pollution-free: This material is a flame retardant material with a flame retardant rating of FV0, a smoke intensity of 15 under high temperature combustion, pollution-free smoke, and a toxicity level of ZA1.

8. Long service life: It has been proven that its service life is at least 20 years or more; The simulated aging test shows that its service life exceeds 20 years, far exceeding traditional materials such as metals.
