Production of standard emblem in repeated experimental practice to draw the conclusion:
1. Production of national emblem with glass fiber reinforced plastic, the advantages: the emblem lighter, easy to install. Disadvantages: With the passage of time, FRP emblem easy to aging deformation.
2. Production of national emblem with iron, the advantages: the emblem is not easy to deformation. Disadvantages: With the passage of time, iron easily oxidized rust, rust water will be infected with the wall, affecting the appearance.
3. Production of national emblem with brass, advantages: the emblem is not easy to deformation, corrosion resistance, long service life. Disadvantages: brass expensive, emblem heavier. The state advocates moderate consumption and green consumption, saving resources.
4. Aluminum alloy production emblem, advantages: the emblem is not easy to deformation, corrosion resistance, long life, easy aging deformation, in the outdoors will not rust, the surface of high temperature paint, bright colors lasting, cheaper prices more affordable, according to the above characteristics , The national standard emblem is generally made of aluminum alloy cast, paste the national emblem service life longer.
