OEM/ODM Aluminium Stacking Doors Manufacturer & Suppliers

Bifold doors fold like an accordion, projecting their folded panels inside or outside the building envelope and loading significant dynamic weight on the overhead track. Stacking doors slide along parallel dedicated ground tracks, with each panel nesting sequentially behind a stationary panel. Stacking doors allow much larger panel glass sizes, provide superior wind-load interlocks, eliminate hinge sagging over time, and do not occupy patio or room space when fully opened.

Our systems utilize heavy-gauge 6063-T6 architectural grade aluminum with up to 3.0mm primary wall thickness. Interlocking stiles incorporate multi-fin EPDM santoprene gaskets and structural steel internal stiffeners. Bottom sills feature stepped sill dams with concealed one-way drainage valves that release internal hydrostatic pressure, preventing water infiltration even under cyclic typhoon gusts up to 4500 Pa.

Yes. As a pure OEM/ODM factory, DERCHI manufactures made-to-order configurations. We produce triple-track (3 panels opening 66%), quadruple-track (4 panels opening 75%), dual-directional bi-parting stacking, concealed wall pocket sliding systems, and 90-degree post-free open corner systems where the two walls slide away completely without a structural column obstructing the panoramic view.

We offer fully tempered insulated glazing units (IGU) conforming to CE and SGCC standards. Standard options include 6mm+12A+6mm double glazed, 5mm+1.52PVB+5mm acoustic laminated glass, as well as triple-pane configurations. Coatings include offline magnetron sputtered Low-E (Single, Double, or Triple silver) filled with 90%+ pure argon gas to achieve customized Solar Heat Gain Coefficients (SHGC) and acoustic ratings (STC up to 42 dB).

For coastal installations within 5km of the sea, we recommend fluorocarbon PVDF coatings (2-coat or 3-coat system conforming to AAMA 2605) or marine-grade seaside pre-treatment anodizing (25-micron thickness). These finishes provide exceptional resistance against UV chalking, saltwater pitting, and abrasive coastal winds, backed by a 15 to 25-year warranty against fading or bubbling.

Following shop drawing confirmation, custom fabrication typically takes 25 to 35 business days depending on volume and hardware specifications. Every door panel is labeled corresponding to the building schedule, wrapped in protective peel-off film, padded with corner edge foam, and secured inside fully enclosed fumigation-free plywood crates with internal steel strapping to allow direct forklift offloading at destination project sites.
