Industrial Capacity & Scale
Why Global Tier-1 Contractors Rely On Our Production Hub
Operating from our 180,000 m² advanced manufacturing facility in Foshan, Guangdong, we merge CNC precision machining, in-house R&D, and complete quality traceability to mitigate supply-chain risks for high-profile developers.
Automated CNC Precision Fabrication
Our Industry 4.0 production lines utilize multi-axis CNC machines to achieve ±0.2mm dimensional tolerances across high-gauge 6063-T5/T6 aluminum extrusions. Every corner joint utilizes mechanical crimping and corner cleat injection bonding for long-term structural integrity.
Patented 4-Side 6-Point Security Locking
Protected by national invention patents, our proprietary four-side six-point interlocking mechanism distributes perimeter compression evenly across the entire frame. This provides anti-jemmy forced entry deterrence alongside unmatched acoustic and air permeability performance.
Compliant Multi-Region Certification
We eliminate regulatory roadblocks by maintaining verifiable test certifications including NFRC (USA), CSA (Canada), ENERGY STAR®, CE, and Hurricane Impact ratings. Every batch is supported by mill certificates, glass test reports, and structural calculations tailored to regional building codes.
BIM & Imperial Shop Drawing Support
Our dedicated 30+ member R&D and engineering bureau converts architectural elevations into rigorous AutoCAD and Revit BIM packages. We confirm rough opening tolerances, perimeter flashing integrations, and dead-load anchor arrangements prior to extrusion release.
Export Plywood Crate Packing
To guarantee zero-damage oceanic transit, every leaf and frame assembly is wrapped with multi-layer protective PE film, corner buffered, and crated in ISPM 15 fumigation-exempt solid timber cases designed for forklift balance and rough job site handling.
Dedicated OEM Partner Programs
Supplying more than 300 international distributors, we provide flexible private-label customization, custom hardware anodizing, exclusive territory agreements, and factory-subsidized showroom display models to accelerate brand scaling.
Industry Whitepaper Report
The Evolution of High-Performance Aluminum Fenestration (2025–2030)
An authoritative engineering assessment of thermal insulation breakthroughs, extreme weather resilience, and digital specification workflows redefining commercial and luxury residential entryways.
Decarbonization & Ultra-Low U-Values
With energy codes like ASHRAE 90.1, Title 24, and Canada's Pan-Canadian Framework tightening operational carbon caps, standard thermal breaks are no longer sufficient. The market is shifting to polyamide (PA66 GF25) multi-cavity thermal barriers coupled with aerogel insulation cores, driving entrance door U-factors down toward ≤0.18 Btu/(hr·ft²·°F).
Oversized Pivot & Minimalist Sightlines
Modern architecture demands monolithic daylight openings. The engineering challenge involves sustaining wind load structural resistance while narrowing visible profile sightlines down to 20mm. Heavy-duty concealed floor pivots supporting door leaves up to 600 kg (1,320 lbs) are replacing standard butt hinges for flagship architectural residential designs.
Severe Storm & Hurricane Resilience
Accelerated climate disruptions have pushed high-velocity hurricane zones (HVHZ) requirements beyond Florida and the Gulf Coast into inland corridors. Future procurement focuses on structural SentryGlas® (SG) ionoplast interlayers and continuous perimeter locking brackets capable of withstanding >±90 PSF design pressures.

Frequently Asked Questions for Project Procurement
Objective technical responses addressing rough opening tolerances, structural certifications, logistics, and private-label manufacturing parameters.
How do you verify compliance with North American local building codes (NFRC, CSA, Florida HVHZ)?
Our architectural aluminum windows and exterior entry systems are tested in accredited independent test laboratories in accordance with AAMA/WDMA/CSA 101/I.S.2/A440 (NAFS), NFRC 100/200/500, and ASTM impact standards. When quoting, we match the exact project elevation, profile alloy, polyamide break dimension, and low-emissivity glass build up against your regional energy rating (ENERGY STAR® zones Northern/Southern) and municipal structural design pressure (DP) criteria, issuing certified physical test reports and stamped engineering documentation.
What is the standard OEM manufacturing lead time, and how are site change-orders handled?
Standard OEM production ranges between 25 and 35 working days post-approval of shop drawings and hardware schedule sign-off. For bespoke extrusions or custom powder coating finishes (such as Qualicoat Class 2 or custom architectural fluorocarbon PVDF), extrusion die machining requires an additional 10 days. We employ a strict freezing point policy: any dimension modifications requested within 7 days of shop drawing sign-off can be accommodated without structural waste.
Can your factory support imperial dimensional sizing and North American rough opening practices?
Yes. Over 65% of our ongoing production is engineered directly for U.S. and Canadian residential and commercial projects. Our engineering team prepares all fabrication prints with dual-dimensioning (inches and millimeters), incorporating standard North American perimeter deductions (1/2" nominal clearance for shim and backer rod sealant application), nailing fin flanges (1-3/8" setback), or masonry clip attachments based on specific wall substrate requirements.
What glass configurations are available for extreme thermal performance and impact resistance?
We operate fully certified automated IGU lines capable of assembling double-glazed and triple-glazed units with warm-edge composite spacers (Swisspacer / Technoform), 95% argon gas filling, and dual coats of magnetron-sputtered soft Low-E glass (such as PPG Solarban 60/70 equivalents). For hurricane and security performance, we incorporate laminated configurations utilizing 0.090" to 0.100" Kuraray SentryGlas® or Solutia PVB interlayers capable of passing large missile impact (TAS 201) testing.
How does your factory ensure zero damage and moisture protection during long-distance ocean shipping?
Every fabricated unit undergoes four protective stages: (1) low-tack protective blue film applied across all visible aluminum surfaces; (2) shock-absorbing high-density polyethylene edge protectors; (3) fully sealed heavy-duty poly vapor bags with continuous industrial silica desiccants to prevent salt-fog condensation; and (4) crating inside fully enclosed, fumigation-free engineered plywood boxes reinforced with internal timber braces and steel strapping. Containers are weight-distributed and air-bag stabilized prior to port clearance.
