When opening aluminum alloy windows, the force should be moderate, and try to keep the speed even when opening and closing. Try to avoid hitting the aluminum alloy window with hard objects or scratching the surface of the profile.
The particles and other debris inside the frame should be cleaned up in time to prevent them from blocking the drainage channel and causing poor drainage and water leakage. When it is found that the opening of the aluminum alloy window is inflexible or other abnormal conditions during use, the cause should be found in time. If the customer cannot solve the fault, he can contact the aluminum alloy door and window manufacturer and supplier so that the fault can be eliminated in time.
