Global Procurement Q&A

What are the primary advantages of Top Hung Casement Windows over Side-Hung? +
Top hung windows allow for ventilation even during light rain, as the sash acts as a natural awning. They also offer better safety in high-rise buildings and don't occupy interior space when opened.
How does Suozhe ensure the durability of the hardware? +
We partner with global hardware leaders (like Siegenia or Hoppe) and subject our systems to 50,000+ cycle tests in our R&D center, ensuring decades of smooth operation.
Can these windows meet local building codes in Europe or North America? +
Yes. With ISO 9001 and our focus on high-performance insulation, our windows are engineered to meet and exceed international standards for thermal efficiency and wind load resistance.
What is the lead time for large-scale industrial orders? +
Thanks to our 60,000 sqm intelligent production base, we typically offer lead times of 25-45 days, depending on the customization level and order volume.
