Slander Door
Explore our precision-engineered entrance solutions, featuring top-grade timber, structural aluminum profiles, and automated heavy-duty systems for global modern constructions.
Modern commercial and residential architectural designs increasingly demand high-span exterior folding door solutions. These doors transition smoothly between interior and exterior spaces, opening up wide panoramas while remaining highly resilient to atmospheric variables. At Zhejiang Slander Door Co., Ltd., we combine state-of-the-art aluminum extrusion technologies with premium components to deliver high-performance folding door systems that satisfy strict mechanical and thermal regulations.
Utilizing high-performance PA66 GF25 polyamide thermal barriers, our systems mitigate thermal bridging, delivering exceptionally low U-values (down to 1.4 W/m²K). This satisfies green building standards and minimizes HVAC loads in cold and extreme heat climates.
Our folding door profiles are extruded from high-tensile 6063-T5 or T6 grade aluminum alloys, engineered to endure heavy wind loads (up to 5000 Pa). This structural security makes them suitable for high-rise balconies and coastal installations.
Equipped with dual or triple EPDM weatherstripping gaskets and top-hung heavy-duty roller systems, these doors operate smoothly. Multiple locking systems offer robust burglar resistance (WK2/RC2 security levels).
Established in 1994, Zhejiang Slander Door Co., Ltd. is a leading enterprise in the high-end architectural door and window manufacturing sector in China. Over the past decades, Slander has pioneered the customized manufacturing of complete door systems, building a solid reputation for delivering custom, premium products tailored to the precise specifications of global builders, architects, and B2B developers.
We provide a comprehensive product range that includes garage doors, rolling shutter doors, folding doors, aluminum-clad wood doors, sunrooms, wrought iron gates, and fence railings. Driven by changing market needs, our portfolio now includes innovative structural solutions such as container houses, Apple houses, and curtain walls, providing a comprehensive, one-stop architectural solution.
With ongoing global economic integration, we have steadily expanded our footprint across Europe, North America, Oceania, and the Middle East, building lasting partnerships with clients around the world. We take pride in delivering custom door systems that improve security, structural performance, and aesthetic value, while maintaining high quality standards.
Sourcing architectural folding doors directly from our production facilities in Zhejiang, China offers direct cost efficiencies, consistent quality control, and the capability to execute complex custom orders. Our industrial integration enables us to deliver top-tier structural solutions at competitive wholesale prices.
From aluminum alloy extrusion and surface finish treatment (PVDF/powder coating) to CNC machining and testing, our processes are centralized. This guarantees quality control and allows us to offer custom solutions tailored to your project requirements.
Our folding door profiles and glazing assemblies conform to European Union standards, carrying compliance certificates for EU No 305/2011 & Directive 89/106/EEC (CPD). This certification verifies that our doors meet safety and thermal requirements for installation across the European Union.
Our engineering division assists architects and contractors with CAD design, shop drawings, wind load calculations, and hardware options. We deliver detailed, transparent quotes within 24 hours of receiving your inquiry.
Sourcing fenestration products internationally requires compliance with local building regulations. We adapt our systems to meet national building codes, ensuring effortless inspections and long-term durability in diverse climates.
For US and Canadian building codes, we customize our profiles to support double-glazed IGUs with Low-E coatings, warm-edge spacers, and Argon gas fill. Our hardware configurations can be specified to meet American architectural requirements, accommodating multi-point locks and flush bolts. We engineer systems with wind-load profiles suited for storm-prone regions, including those demanding impact-resistant glass configurations.
We configure folding systems for Australia and New Zealand to meet AS2047 structural and weatherproofing requirements, alongside AS1288 safety glass regulations. Our profiles undergo water penetration, deflection, and air infiltration testing. Standard options include matching fly screens and insect protection systems suitable for the Oceanic climate.
Equipped with corrosion-resistant 316 stainless steel hardware components and marine-grade powder-coated finishes to resist salt spray erosion.
Featuring wider thermal breaks (up to 34mm) and triple-pane glass configurations to optimize insulation and prevent indoor condensation.
Designed with low-profile thresholds to comply with accessibility requirements (such as ADA regulations) in retail and hospitality properties.
A collection of frequently asked questions regarding technical properties, structural testing, and direct import procedures for our folding door systems.
Select from our structural bi-folding glass options, thermal break patio doors, security grilles, and insect-screen solutions built for residential and commercial demands.
