Tianjin Kross Window & Door Technology Co., Ltd. has evolved into a cornerstone of global facade engineering since 2015. With a 35,000 sqm facility and an annual export value exceeding $31M, we redefine the "China Wholesale" model through R&D-driven manufacturing. We provide more than just products; we provide climate-specific architectural solutions, adhering strictly to international building codes like NFRC, Miami-Dade Hurricane standards, and Euro-norm thermal requirements.
The global construction market is witnessing a paradigm shift. Procurement officers are no longer just looking for "cheap aluminum." The current demand is for **Energy Efficiency** (thermal break systems), **Biophilic Design** (large-span glass panels), and **Smart Automation**. As a leader in the segment, OUNA leverages high-precision CNC manufacturing and rigorous QC (42 technicians) to guarantee structural integrity that meets the strictest international environmental standards.
E-E-A-T is not just a buzzword; it is our operational backbone. With 11 years of industry experience, we understand the regulatory friction in North American, European, and Australian markets. From fireproofing to acoustic insulation and hurricane-rated impact resistance, our 58-person R&D team ensures every batch of aluminum doors and windows is compliant with local site conditions, ensuring seamless installation for facade contractors.
