4. wind pressure resistance: in the independent plastic cavity, 1.5~3mm thick steel lining can be added to enhance the wind pressure resistance.
5. Corrosion resistance: plastic steel profile has a unique formula and good corrosion resistance, long service life.
6. Weather resistance: plastic steel profiles can be used for a long time in a large temperature difference environment, sun exposure, moisture will not make it appear deterioration, aging, embrittlement and other phenomena.
In addition, plastic steel profiles also have the advantages of light weight, high specific strength, good processing performance, rich colors, and low cost.
