Yesterday, we had the pleasure of welcoming our valued customer to the factory for an in-depth visit and discussion. It was a great opportunity for both sides to communicate face-to-face and further strengthen our cooperation. During the visit, our team guided the customer through our production workshop, showing the full process of manufacturing windows and doors—from raw material selection to final assembly and quality inspection. The customer showed strong interest in our product structure, especially our aluminum systems, as well as our fire-rated door solutions. We also arranged a detailed meeting to discuss project requirements. Topics included product specifications, glass configurations, hardware options, and certification standards. Our technical team provided professional suggestions to ensure the products meet both performance requirements and local regulations. The discussion was productive and efficient. We carefully reviewed drawings, confirmed key dimensions, and clarified several important technical points. This direct communication helped avoid misunderstandings and ensured a smoother process for the next steps. In addition, the customer expressed satisfaction with our manufacturing capabilities, quality control system, and overall factory management.

We are excited to share the highlights of our successful participation in the 2026 International Builders’ Show (IBS) in Orlando, Florida. The event was a fantastic platform for connecting with builders, contractors, and distributors from across the United States. During the show, we presented our complete range of windows and doors, featuring PVC, aluminum, steel, and fire-rated models. By showcasing the actual products, we invite visitors to directly experience the quality, durability, and clean, modern design that define the KDSBuilding brand. A major point of interest was our commitment to certification and safety. All our products undergo NFRC testing, and we have actively applied for official NFRC certification as well as Florida Product Approvals. This proactive step demonstrates our dedication to meeting rigorous North American standards for energy efficiency, proving that our solutions are built to perform and comply with local regulations. Also, our fire rated doors get UL certification to meet International Standards. Our team enjoyed in-depth discussions about product specifications, the certification process, and the wide range of customization options we offer. The feedback was overwhelmingly positive. Many attendees specifically praised the energy efficiency, fire safety ratings, and the smooth, reliable operation of our hardware. And many visitors from construction side discuss the details of price for shipping. This show reaffirmed our mission: to deliver high-quality, certified, and reliable door and window solutions for both residential and commercial projects.
