Aluminium Stacking Doors Factory & Exporter for Colombia

Bogotá sits at 2,640 meters above sea level, where atmospheric pressure is approximately 25% lower than at our sea-level production base in Foshan. Without pressure equalization, the internal pressure of sealed double or triple glazed units will cause outward bowing, seal rupture, and eventual fogging. For all shipments destined for the Cundinamarca and Boyacá departments, we install calibrated stainless steel capillary breathing tubes into the spacer bar during fabrication. Once the units arrive at the job site in Bogotá, our installation protocols guide local contractors on permanently crimping and sealing the tubes, preserving the thermal seal and preventing condensation permanently.

We maintain direct long-term shipping allocations departing from Nansha, Shekou, and Yantian (Shenzhen) to Colombia’s two primary maritime hubs: Puerto de Buenaventura (Pacific corridor serving Cali, Medellín, and Bogotá via overland transport) and Puerto de Cartagena / Barranquilla (Caribbean corridor). Maritime transit time typically ranges between 32 to 42 days. Factory fabrication requires 30 to 40 days depending on extrusion anodizing or custom RAL powder coating requirements. Complete export packages include commercial invoices, packing lists with opening IDs, Bills of Lading, and certified mill test reports.

Yes. Our engineering division reviews your project's structural calculation reports and floor plans prior to cutting profiles. In accordance with Title A and Title K of Colombia's NSR-10 regulation, our heavy-duty sliding and stacking doors use virgin 6063-T6 or 6061-T6 aluminum alloys with internal steel or heavy-gauge aluminum stiffeners inside the interlocking vertical stiles. This enables large glazed spans (up to 3.5m height per sash) to withstand wind pressures exceeding 2.5 kPa without exceeding allowable deflection limits (L/175 or L/240), preventing frame dislodgement during seismic vibrations.

Tropical downpours in regions like the Chocó, Quindío, and Antioquia generate intense water intrusion risks. Our heavy-duty aluminium stacking doors feature a stepped, cascading water-drainage sub-sill equipped with internal anti-backflow weep holes and concealed gravity-fed drainage channels. High-density, multi-layer vulcanized EPDM continuous gaskets and silicone fin-pile weather-stripping provide watertight sealing up to 600 Pa, effectively eliminating water penetration under severe driven rain.

For coastal environments (Cartagena, Santa Marta, Barranquilla), we strictly specify fluoropolymer PVDF coatings (KYNAR 500) or Qualicoat Class 2 architectural powder coatings with a minimum dry film thickness of 60-80 microns, tested for 3,000+ hours in neutral salt spray chambers. Alternatively, class AA25 anodized finishes offer superior hardness. For inland Andean areas (Bogotá, Bucaramanga, Manizales), Qualicoat Class 1 polyester powder coatings with high UV-stabilization are ideal for resisting high-altitude ultraviolet radiation degradation and chalking.

For custom engineering and real estate developments, our standard MOQ is 50 square meters (or composite villa packages). However, we routinely support pre-production mockup units (PMU) for developer validation, architect physical review, and local laboratory testing. Hand corner sample cases displaying thermal break cross-sections, finish swatches, and hardware sets are air-shipped directly to your office in Colombia via DHL/FedEx within 5-7 business days.
