In the evolving landscape of modern architecture, fold and slide doors—often referred to as bi-fold or multi-slide systems—have become the hallmark of indoor-outdoor living. As a premier China manufacturer and factory, we specialize in producing the high-precision aluminum extrusions that serve as the backbone of these structural wonders. Our commitment to quality, backed by ISO9001 and IATF16949 certifications, ensures that every profile meets the rigorous demands of global construction projects.
Aluminum is the superior choice for fold and slide door systems due to its high strength-to-weight ratio, durability, and resistance to environmental factors. Unlike wood or PVC, our 6063 and 6061 aluminum alloys offer the structural integrity required to support massive glass panels while maintaining a slim profile that maximizes aesthetic appeal and daylight penetration. Our expertise in surface treatment—including anodizing and powder coating—ensures that these doors withstand harsh weather conditions, making them ideal for both high-end residential estates and heavy-duty industrial applications.
Qingdao Kangjian Aluminum Industry Technology Co., Ltd. sits at the heart of this manufacturing prowess. With a production base covering 80,000 square meters and an annual capacity of 15,000 tons, we leverage economies of scale and cutting-edge technology to deliver cost-effective, premium-grade profiles. From 1450T to 2500T extrusion units, our machinery allows for intricate designs, customized mechanical structures, and rapid prototyping that aligns with the speed of global markets.
Located in Jimo District, Qingdao, we have established ourselves as a global leader in aluminum profile manufacturing. Since 2022, we have expanded from a local powerhouse to an international exporter. Our "dual-sea layout"—utilizing Qingdao's port advantages—allows us to seamlessly supply markets in South Korea, Japan, the United States, and Europe.
Core Capabilities:
Global demand for aluminum profiles is shifting toward sustainability and high energy efficiency. Our thermal break technology and eco-friendly finishing processes are helping builders meet new green building standards. When sourcing from a China factory, procurement managers look for three things: Reliability, Precision, and Logistics.
Our profiles are engineered for high-frequency use. Using T5/T6 heat treatment, we ensure the aluminum maintains its shape over decades, even in heavy-traffic environments.
Yes, we offer full-service customization. From drawing approval to prototype and mass production, we act as an extension of your own manufacturing team.
Being based in Qingdao, we have direct access to major international shipping routes, ensuring efficient logistics and reduced lead times for global clients.
