铝合金门窗较之木质装饰门窗以及渐被淘 汰的普通空腹或实腹钢门窗具有突出的使用性能，其风压强度性能、空气渗透性能、雨水渗漏性能、空气声隔声性能、隔热保温性能及启闭性能等，均达到的国家标准规定；且由于铝合金材质的特点，使其加工制作、铝型材装配JDG金属穿线管 不锈钢链板 隔离墩模具 检查井钢模具 流水槽模具 阶梯护坡模具 护坡砖模具 遮板模具 及制品安装可以达到较高的精度，为建筑围护结构的节能设计及使用安全等标准要求提供了重要和必要的条件。
Compared with wooden doors and windows, aluminum alloy doors and windows are gradually being washed out The ordinary open web or solid web steel doors and windows have outstanding performance, its wind pressure strength performance, air permeability, rain water leakage performance, air sound insulation performance, heat insulation performance and opening and closing performance meet the national standards; and due to the characteristics of aluminum alloy material, its processing, aluminum profile assembly and product installation can achieve high precision The energy-saving design and safety standards of building envelope provide important and necessary conditions.
