We offer three types of professional packaging to ensure product safety during transit: bubble bags, bubble bags with wooden frames, and bubble bags with wooden cases. For full container loads, bubble bags are recommended to maximize space efficiency. For bulk cargo or specific international standards (USA, Australia, Europe), wooden cases provide the ultimate protection for high-value windows and doors.
With over 15 years of manufacturing expertise, we operate a 10,000 square meter facility with an annual production capacity reaching 100,000 square meters. We specialize in high-end aluminum and UPVC windows, energy-saving passive house systems, and customized glass solutions for global markets including North America, Europe, and Australia.
Quality Assurance: We utilize German-imported Renolit films designed to prevent fading and peeling for up to 30 years, ensuring your investment remains aesthetically pleasing and functionally superior for decades.
