About Guangzhou Ronch Mark Birch


Founded in 2015, Guangzhou Ronch Mark Birch Industry & Trade Co., Ltd. is a vertically integrated manufacturer and global supplier specializing in architectural hardware—namely window rollers, bearings, window locks, and door hinges for modern fenestration solutions.


Since our founding, we have built a reputation for engineering excellence, competitive pricing, and responsive customer service. Backed by a professional in-house team for product design, mold development, and material innovation, we focus on delivering both standard and custom-engineered components that meet the evolving demands of global construction markets.


Our Vision



At Ronch Mark Birch, our vision is to be the preferred choice for global partners seeking exceptional window and door hardware system solutions. We strive to combine systemic innovation, precision craftsmanship, and dedicated OEM/ODM service to engineer hardware systems—including high-performance window rollers, window locks, and door hinges—that not only meet but exceed our customers’ expectations.



Integrated System Craftsmanship


We take immense pride in delivering comprehensive window and door hardware system solutions. Rather than just fabricating individual components, we engineer integrated systems where our aluminum sliding door rollers, high-security UPVC window locks, and heavy-duty door hinges operate in perfect harmony. Every solution is meticulously tested to ensure seamless compatibility, optimal structural performance, and long-lasting durability for the entire fenestration system.



Customization for You


We understand that every architectural project requires a unique, cohesive hardware ecosystem. That’s why we offer end-to-end OEM and ODM system customization. Whether you are developing complex aluminum sliding structures or high-insulation UPVC profiles, we work closely with your technical teams to design and manufacture custom window rollers, window locks, and heavy-duty hinges that form a fully integrated hardware configuration matching your exact local building standards.



Innovative System Architecture


At Ronch Mark Birch, we are shifting the boundaries from single-part manufacturing to complete system architecture. Our in-house engineers consistently innovate to bring cutting-edge load-bearing technologies to our sliding door rollers and advanced security mechanisms to our UPVC window locks. By treating these components as a unified building envelope system, we maximize the lifecycle cost optimization and safety of your complete door and window installations.



Comprehensive System Portfolio


Our portfolio is structured around high-performance, ready-to-install hardware packages for various building techniques. By offering a complete range of aluminum sliding door rollers, window locks, and heavy-duty door hinges under one roof, we eliminate the hassle of multi-vendor sourcing. We provide fully compatible system solutions, serving as a single, accountable partner for profile integrators, project contractors, and global OEM brands worldwide.



Global Reach & Value-Added Partnerships


We emphasize material performance, precision manufacturing, and lifecycle cost optimization. Whether serving OEM clients, project contractors, or distributors, we are committed to reliability, consistency, and value-added partnerships. With a strong footprint across Europe, Southeast Asia, the Middle East, and Latin America, Ronch Mark Birch is positioned as a trusted partner for durable, high-performance window hardware at scale.
