detail


Generally speaking, high-performance aluminum alloy doors and windows are usually more expensive than steel model aluminum folding sliding doors, but from long-term consideration, although high-performance aluminum alloy doors and windows are expensive, but because of the strength and elastic modulus of material and wear-resisting performance difference is larger, so high-performance aluminum alloy doors and windows can use longer time, is a preferential choice.
