Slander Door
In the era of sustainable urban development, insulated glass doors have transitioned from a luxury component to a mandatory architectural requirement. As a premier OEM/ODM exporter, we leverage advanced thermal-break technology and Low-E glazing to address the global demand for energy-efficient building envelopes. Our systems are engineered to provide more than just entryways—they are sophisticated thermal barriers designed to minimize Carbon Footprints while maximizing aesthetic transparency.
Our Insulated Glass Units (IGU) utilize Argon-filled cavities and warm-edge spacers to reduce U-factors by up to 45%, significantly lowering HVAC costs for commercial and residential projects.
We provide full-spectrum customization—from profile extrusion and powder coating to bespoke hardware integration, ensuring that your unique architectural vision is realized with precision.
Adhering to EU No 305/2011 and CE standards, our manufacturing processes ensure that every door exported meets the rigorous safety and performance benchmarks of North American and European markets.
Zhejiang Slander Door Co., Ltd. is the leader in the garage door and rolling shutter door industry in China. Founded in 1994, Slander has established itself as a pioneer in the customized manufacturing of door systems, specializing in delivering top-quality products tailored to the specific needs of our customers.
We offer a wide range of solutions, including garage doors, rolling shutter doors, folding doors, aluminum-clad wood doors, sunrooms, wrought iron gates, fence railings, and more. Our R&D team continuously integrates cutting-edge designs like container houses and high-rise building curtain walls into our portfolio.
Based in the heart of China's industrial zone, we have direct access to high-grade aluminum and specialized glass suppliers, allowing us to maintain competitive pricing without compromising quality.
We invest 15% of our annual revenue into material science, focusing on vacuum glazing and smart-glass integration that responds to light and temperature automatically.
Our experienced export team handles everything from custom crating to international shipping logistics, ensuring that our insulated glass doors arrive on-site, damage-free and ready for installation.
The industry is moving towards Minimalist Framing (Slim Frames) and Zero-Threshold Designs. We are at the forefront of this movement, developing thermal-break systems that allow for floor-to-ceiling glass expanses while maintaining a structural integrity that withstands high wind loads in coastal regions. Furthermore, the integration of AI-controlled automation—as seen in our radar-sensor series—is becoming standard in high-end residential and commercial sectors.
Providing robust, high-traffic insulated glass doors for shopping malls, airports, and office towers. Our focus is on durability and the "Safety Beam" technology which prevents accidents in high-occupancy environments.
Designing "Four Seasons" conservatories and bi-folding patio doors that blend indoor and outdoor living. Our Wood-Texture Aluminium finishes provide the aesthetic of timber with the lifespan of metal.
Our thermal-insulated overhead doors are specifically designed for logistics hubs and climate-controlled warehouses, where maintaining temperature stability is critical to operational success.
Developing solar-ready glass solutions and recycled-aluminum profiles to meet the LEED and BREEAM certification requirements of modern green buildings.
Procuring door systems internationally requires a partner who understands more than just manufacturing. At Zhejiang Slander, we act as architectural consultants, providing detailed CAD drawings, BIM models, and structural calculations to ensure our products fit perfectly into your project's technical framework.
For standard custom glass door configurations, our production lead time is 25-35 days from the confirmation of technical drawings. High-volume ODM projects may vary based on material availability.
We utilize dual-seal technology (PIB and Silicone) and perform Argon gas concentration tests on every batch. Our IGUs are tested for dew-point and thermal transmittance (U-value) before shipping.
Yes. We offer a wide range of hardware brands (including ROTO, GU, and our proprietary high-performance systems) to ensure compliance with ADA, fire safety, and emergency egress codes in different countries.
We provide comprehensive 3D installation manuals and video guides. For large-scale commercial projects, we can arrange for a technical supervisor to provide on-site training for your local installation team.
Our products are fully compliant with EU No 305/2011 and Directive 89/106/EEC (CPD), covering everything from wind resistance and water tightness to mechanical strength.
We use fumigated plywood crates with shock-absorbing foam and vacuum sealing to prevent oxidation of metal parts and breakage of glass during long-distance maritime transport.
