Who are we?
We are a leading high-quality supplier specializing in engineering doors and windows, with 25 years of profound industry experience, rooted in Hangzhou, Zhejiang Province.
Are your slim frame sliding doors certified for energy efficiency and weather resistance?
Yes, our multi-slide patio doors are NFRC-rated (National Fenestration Rating Council) and fully compliant with high energy-efficiency standards. They feature state-of-the-art thermal break aluminum profiles and high-specification fully tempered double/triple glazing (e.g., 5mm+12Ar+5mm) with advanced Low-E coating and insulating argon gas filling. This ensures outstanding thermal insulation, massive energy savings, and excellent acoustic soundproofing.
Can the bottom floor track be completely flush and hidden with our flooring?
Absolutely! We specialize in minimalist architectural aesthetics and offer two advanced threshold track options: Integrated Floor-Insert Track (allowing floorings to be embedded directly into track gaps for a 100% seamless look) and Flat Aluminum Alloy Cover Plates (preventing dust accumulation and providing a barrier-free walkway).
What is the maximum customizable height and width for these patio doors?
We possess industry-leading structural engineering capabilities and can customize floor-to-ceiling sliding glass walls up to a maximum height of 9 meters (approx. 29.5 feet). The system supports 2-track, 3-track, 4-track, and virtually unlimited track configurations with multi-panel linkages, as well as 90-degree column-free corner pocket designs.
How do you guarantee security and anti-theft performance with such thin frames?
Security is our top priority. Our ultra-slim slide doors are equipped with premium German-imported heavy-duty multi-point interlocking systems. Heavy-duty L-shaped mechanical lock hooks engage seamlessly into hidden catch points, and standard fully tempered safety glass ensures exceptional anti-forced entry and wind-load performance compliant with PAS 24 security standards.
Can we customize the frame colors and what surface treatment is used?
Yes, we offer 100% custom colors using premium AkzoNobel architectural powder coating supporting the entire RAL chart. The coating provides exceptional resistance against UV rays, salt spray, and extreme temperatures, ensuring a durable, fade-free, and peel-free service life.
