OEM/ODM Aluminium Patio Doors Manufacturers & Manufacturer

Standard inline sliding patio doors rest on track-mounted rollers permanently, relying on weatherpile brush seals that encounter friction with each slide. In contrast, Lift & Slide (Hebeschiebe) systems utilize specialized internal gear mechanisms: when the handle is turned downward 180°, the entire sash physically elevates 5mm off the sill, disengaging dual continuous EPDM compression gaskets. This eliminates friction during movement and permits sash weights from 300kg to over 600kg. Once lowered into lock position, the heavy sash compresses the perimeter gaskets directly against the aluminium frame, delivering unmatched air permeability (Class 4), water tightness (over 900 Pa), and structural wind resistance up to 3000 Pa.

To meet overall U-value metrics below Uw ≤ 1.2 W/m²·K, we replace simple thermal insulators with custom PA66 GF25 (polyamide reinforced with 25% structural glass fiber) struts measuring between 24mm and 34mm in cross-section. The extruded hollow internal cavities are injected with aerogel or high-density expanded polyurethane insulation bars. When married to a 42mm triple-glazed IGU configuration (e.g., 6mm Low-E + 12A Argon + 6mm Clear + 12A Argon + 6mm Low-E with warm-edge composite spacers), the overall patio door assembly completely blocks conductive and radiative thermal bridging, meeting Passivhaus requirements.

For oceanfront hotels, coastal villas, or tropical installations, standard electrostatic powder coating can deteriorate rapidly under continuous salt fog exposure. We specify AkzoNobel Interpon D2525 or Tiger Drylac architectural fluorocarbon (PVDF) 3-coat systems, carrying Qualicoat Class 2 accreditation. Alternatively, we offer mechanical Class 20/25 deep anodized treatments with film depths ≥ 20μm. These coatings are tested to endure over 3,000 to 5,000 hours of continuous neutral salt spray (NSS per ISO 9227) without bubbling, filiform corrosion, or color fading.

For OEM/ODM customized orders, our engineering and shop drawing sign-off takes 3–5 working days; tooling of custom extrusion dies takes 12–15 days; mass fabrication and assembly take 25–35 days depending on project volume. Our flexible factory infrastructure accommodates bespoke villa orders (MOQ starting at 20 m²) up to full 40ft High Cube container loads for regional importers. For shipping protection across international routes (e.g., to Rotterdam, Hamburg, Felixstowe, Long Beach, or Sydney), all units receive a 5-layer crating treatment: peelable surface protective films, PE foam cushioning, impact-resistant paper corner guards, multi-layered bubble wrapping, and fully enclosed IPPC-certified fumigated plywood crate containers loaded with desiccant packs.
