Engineered for extreme structural load, weather sealing, sound attenuation, and maximum visible glass area.
Foshan Primeval Doors Industry Co., Ltd. represents the apex of structural aluminum door fabrication, backed by decade-long engineering precision and global compliance capabilities.
Established in 2017, Foshan Primeval Doors Industry Co., Ltd. operates from a high-tech manufacturing center spanning over 12,000 square meters in the heart of China’s architectural metal hub. Backed by 11 years of structural engineering experience and 5 years of dedicated international export operations, the company maintains an impressive annual export volume reaching USD 8,500,000 across North America, Australia, New Zealand, and Europe.
Quality assurance is systematically executed through strict IQC-IPQC-FQC inspection protocols. Every batch of profile extrusions undergoes rigorous thermal conductivity testing, salt-spray corrosion resistance evaluation, and mechanical tension verification. Managed by 22 senior QC inspectors, our operations incorporate direct OEM export and private-label customization tailored specifically to real estate developers, window importers, architectural designers, and general contractors.

Aluminum stacker doors (also classified as multi-slide telescoping doors) differ fundamentally from traditional two-panel sliding patio doors. By utilizing multi-track frame extrusions—ranging from 3-track to 6-track configurations—stacker doors allow multiple moving sash panels to slide smoothly along parallel tracks and stack neatly behind a single fixed panel or into a wall pocket. This design converts up to 75% to 83% of the total wall opening into usable open-air transition space.
To support heavy glass loads (exceeding 250 kg per sash), our stacker systems employ high-tensile 6063-T5 and T6 structural aluminum alloys with wall thicknesses exceeding 2.0mm to 3.0mm. Precision-engineered stainless steel quad-wheel rollers with sealed ceramic bearings ensure frictionless slide cycles rated for over 100,000 operations under continuous load.
In modern architectural design, energy conservation is governed by stringent codes such as California Title 24, Australia AS2047, and European CE Passive House Standards. Uninsulated aluminum profiles suffer from high thermal conductivity (K-value of raw aluminum is ~200 W/m·K). Our stacker doors resolve this via advanced thermal break design.
By inserting high-density Polyamide PA66-GF25 (25% fiberglass reinforced) structural thermal barrier strips between the inner and outer aluminum extrusions, thermal bridge pathways are severed. When paired with double or triple-glazed Low-E insulated glass units (IGUs) filled with 90%+ Argon gas and warm-edge spacers, overall window U-factors decrease to less than 1.4 W/m²·K (0.25 BTU/h·ft²·°F), achieving Solar Heat Gain Coefficients (SHGC) down to 0.22.

Specifically engineered for coastal hurricane exposure (such as Florida NOA standards), our heavy-duty interlockers utilize internal steel reinforcements and multi-point locking hooks to resist severe wind forces and flying debris impacts.
Utilizing magnetron sputtering silver-layer Low-E coatings on ultra-clear tempered glass, our stackers reflect infrared heat while maximizing visible light transmission (VLT > 70%), dramatically reducing HVAC cooling loads.
Equipped with German-engineered Siegenia or Hoppe heavy-duty D-handles and hardware. Concealed stainless steel multi-point locking gear prevents forced entry attempts at perimeter locking nodes.
