The folding opening mechanism features a postless corner design for maximum opening space, offering an uninterrupted, expansive view. Concealed hinges and roller components contribute to a stylish, elegant, and sophisticated appearance.The middle mullion is reinforced to enhance wind resistance, ensuring balanced stress distribution across the entire door panel to prevent sagging. The upper part of the door panel incorporates a spring-damped sliding wheel, while the lower part uses a support-type multi-roller design paired with stainless steel tracks. This ensures that folding and sliding operations are lightweight, smooth, and efficient.
