Price: The price of UPVC is relatively low, while the price of aluminum alloy is relatively high.
Performance: The strength and hardness of UPVC are relatively low, while the strength and hardness of aluminum alloy are relatively high.
Corrosion resistance: UPVC performs poorly in corrosion resistance, while stainless steel performs better in corrosion resistance.
In summary, UPVC profiles and aluminum alloy profiles each have their own advantages and disadvantages, and they need to be considered according to specific needs and conditions when choosing to use them.
