Top Trusted Aluminium Double Sliding Doors Manufacturer & Supplier

A conventional double sliding door rests directly on its weather pile or brush seals while traveling along the bottom track, which creates operational friction and eventual seal degradation. A Lift & Slide system uses specialized lever-action gearing: turning the operating handle 180° physically lifts the door leaf off its compressed continuous perimeter EPDM gaskets onto frictionless wheels before moving. When closed and latched down, the leaf's weight compresses the seals onto the frame, achieving unprecedented air tightness, acoustic dampening (up to 45 dB), and hurricane-grade water exclusion up to 750 Pa.

For coastal zones within 5km of saltwater (e.g., Lagos, Durban, Miami, Sydney), standard polyester powder coating will suffer filiform corrosion within 3-5 years. We specify PVDF (polyvinylidene fluoride) fluorocarbon coatings (70% Kynar 500 resin base, 2-coat or 3-coat system) or Class I Architectural Anodizing (minimum 25-micron thickness, QUALANOD certified). These surface chemistries resist extreme salt spray (exceeding 3,000 hours under ASTM B117 salt fog testing) and heavy ultraviolet degradation.

Yes. Every double sliding door glass package is fully customized to project climatic demands. Options include insulated glass units (IGU) featuring tempered safety glass (6mm+12A+6mm up to 8mm+16A+8mm), filled with 90%+ pure argon gas, warm-edge composite spacers, and dual or triple soft-coat Low-E layers. For equatorial and high-solar radiation regions, we combine solar-reflective tinted panels to maintain a Solar Heat Gain Coefficient (SHGC) below 0.28, noticeably reducing building HVAC cooling loads.

All doors undergo factory pre-assembly and functional testing before being broken down into knock-down (KD) or semi-assembled configurations, depending on container loading optimization. Profiles are wrapped in protective polyethylene films, fitted with heavy-density foam corner protectors, and sealed into completely enclosed, ISPM-15 heat-treated non-coniferous plywood crates. We provide detailed container layout plans to maximize volume, balance weight distribution, and eliminate transit shifting across oceanic shipping lanes.

We provide full documentation kits to assist local clearing agents and building code officials. This includes CE Declarations of Conformity, AS2047 structural and wind-pressure test reports (certified for cyclonic areas), NFRC thermal performance ratings, ISO9001 factory audits, and UL fire-rating certificates for applicable models. In addition, we coordinate specialized import documentation such as SONCAP (Nigeria), KEBS PVoC (Kenya), and SASO/SABER compliance certificates.

To generate an accurate proposal, please send: (1) Rough opening dimensions (Width × Height) and quantity; (2) Preferred operational system (Double sliding, multi-track bypass, or Lift & Slide); (3) Glass configuration (Clear double glaze, Low-E, laminated, or acoustic); (4) Desired frame color/finish (Anodized, PVDF, powder coat); and (5) Project location with destination seaport.
