嵌入式五金系统，与窗框设计浑然天成。304 不锈钢双轨道，强度更高，推拉阻力小，使用更顺畅。高隔热断桥型材，隔热保温双效合一，可单独配置室内室外双色需求。

The embedded hardware system is a natural fit with the window frame design. 304 stainless steel double track, higher strength, low push-pull resistance, smoother use. High-insulation bridge-breaking profile, double-effect of heat insulation and heat preservation, can be separately configured for indoor and outdoor double-color requirements.
