Get CatalogVietnam's architectural and construction sectors are undergoing an unprecedented structural transition. Accelerated urbanization across major metropolitan hubs—such as Ho Chi Minh City, Hanoi, Da Nang, and Haiphong—coupled with massive Foreign Direct Investment (FDI) into industrial zones (e.g., VSIP, Becamex, Deep C), has altered structural engineering specifications. Modern high-rise residential towers, commercial complexes, and coastal resorts now demand envelope systems capable of weathering severe tropical environmental stressors while satisfying stringent national energy standards.
Traditional window fenestration materials, including unreinforced uPVC and low-grade unalloyed aluminum profiles, are rapidly being phased out by Vietnamese specifiers and tier-1 main contractors (such as Coteccons, Hòa Bình Construction, and An Phong). The primary catalyst behind this transition is Vietnam's geographical vulnerability to extreme weather events:
Coastal provinces in Northern and Central Vietnam face gust speeds up to 160 km/h (Typhoon Zone 3 & 4), creating peak negative wind suction forces exceeding 2.0 to 2.5 kPa on glass sliding facades.
Average annual humidity levels exceeding 80–85% trigger rapid galvanic corrosion and coating degradation on sub-standard metal profiles lacking specialized chromate-free pre-treatment.
High UV exposure in Southern Vietnam leads to rapid thermal expansion and coating chalking on architectural finishes, necessitating Qualicoat Class 2 fluorocarbon (PVDF) coatings.
An engineering-first approach requires custom window profile configurations tailored to specific Vietnamese microclimates and architectural typologies. As a direct exporter and extrusion partner, our structural engineering team custom-tailors system dies for four primary regional applications:
In dense urban centers like District 1, District 2 (Thủ Đức), and Nam Từ Liêm, acoustic damping and air-tightness are paramount. Urban sound pollution averages 75–85 dB along major arterial expressways (e.g., Vo Van Kiet, Ring Road 3). Our multi-track aluminum sliding window systems incorporate multi-chamber 6063-T6 extrusions with dual-layer EPDM perimeter gaskets, achieving sound transmission class (STC) ratings exceeding 40 dB when integrated with double-glazed acoustic laminated glass.
Concealed drainage channels within the sill extrusions feature gravity-fed anti-backflow flap valves, preventing monsoon rainwater from penetrating interior living spaces during high-pressure tropical downpours.
Vietnam's 3,260 km coastline exposes beachfront structures to relentless airborne sodium chloride (salt spray) and cyclic wind dynamics. Standard mill-finish or commercial-grade anodized aluminum rapidly suffers from filiform corrosion and pitting within 12–18 months.
For coastal resort specifications, we supply 5052-H32 / 5083-H116 alloy plates and architectural profiles coated with 3-coat/2-bake Fluorocarbon (PVDF) liquid spraying or Electrostatic Powder Coating exceeding 25 microns in anodic film thickness (ISO 7599 compliant). These systems undergo a 3,000-hour neutral salt spray (NSS) test without film blistering or adhesion loss, guaranteeing pristine aesthetics for luxury hospitality projects.
Vietnam's rise as a high-tech electronics manufacturing hub (housing major plants for Samsung, Foxconn, and Intel) has elevated demand for industrial-grade sliding aluminum frames within ISO Class 5–8 cleanrooms and manufacturing facilities. Our custom CNC-machined 6061-T6 structural sliding frames feature ultra-smooth flush tracks, non-outgassing silicone perimeter seals, and anti-static powder coatings that resist harsh chemical wipe-downs using isopropyl alcohol and hydrogen peroxide vapor.
The Vietnamese construction industry is experiencing a paradigm shift driven by government sustainability commitments (Net-Zero by 2050 pledge made at COP26) and updated national building codes:
The Vietnam Ministry of Construction strictly enforces energy efficiency mandates. Commercial building envelopes must limit overall Solar Heat Gain Coefficient (SHGC) and lower thermal transmittance (U-factor) below 3.0 W/m²·K.
Institutional developers increasingly seek VGBC LOTUS Green Building certification. Thermally broken aluminum sliding window profiles with Technoform PA66 nylon strips directly contribute points toward building thermal envelope optimization.
Modern Vietnamese residential architecture favors floor-to-ceiling glass sliding doors and narrow profile sightlines (under 35mm interlock width), requiring higher tensile strength 6061-T6 alloy profiles to prevent deflection under wind load.
Understanding the metallurgical and mechanical differences between generic domestic extrusions in Vietnam and our precision export-grade window systems is essential for B2B procurement directors and structural engineers:

HAQ Aluminium represents the pinnacle of a family-owned industrial group established in 1972. Spanning over five decades in metal trading, rolling, rebar steel production, and precision extrusion, our company operates with an unyielding commitment to metallurgical integrity. We control every stage of the manufacturing chain under a single roof:
Procurement decisions for commercial aluminum sliding window projects involve complex technical, customs, and logistical variables. Below are authoritative answers to the most common questions raised by Vietnamese importers, developers, and facade contractors:
Our thermal break sliding window series utilizes multi-cavity aluminum extrusion profiles interrupted by high-grade PA66 GF25 (25% glass fiber reinforced polyamide) insulation strips. This mechanical barrier reduces frame thermal conductivity (U-frame value) down to 1.8 W/m²·K. When paired with double-glazed Low-E glass, the total window assembly easily complies with the maximum allowable heat transfer standards stipulated by the Ministry of Construction for commercial office and residential towers.
We provide full export documentation support for sea freight arriving at major Vietnamese ports including Cảng Cát Lái (HCMC), Cảng Hải Phòng, and Cảng Đà Nẵng. We supply Certificate of Origin (Form E under the China-ASEAN Free Trade Area agreement), allowing qualified Vietnamese importers to claim preferential import tariff rates (often reduced from standard MFN rates down to 0% - 5%). Each shipment includes Mill Test Certificates (MTC) compliant with EN 10204 3.1, Commercial Invoices, Packing Lists, and Bill of Lading (B/L).
Yes. Our tooling workshop specializes in custom die development. Whether you require exact dimensional matching for local Vietnamese profile series (such as System 55, System 93 sliding, or System 65 curtain wall) or completely proprietary custom OEM extrusions, you can send us a DXF file or physical sample. We evaluate press tonnage, wall thickness ratios, and circumscribing circles, produce a custom die within 10 to 15 days, and provide first-article extruded samples for your lab inspection prior to mass production.
Our 6063-T6 and 6061-T6 heavy-duty sliding window series feature high moments of inertia (Ix and Iy values) along the vertical mullion and interlock sections. Tested under ASTM E330 structural wind load protocols, our heavy-duty profiles withstand positive and negative pressures up to 3,000 Pa (equivalent to Category 4 typhoon wind speeds exceeding 200 km/h) with structural deflection remaining under L/175, ensuring complete structural safety for coastal developments in Central Vietnam.
Standard MOQ for existing profile dies is typically 500 kg to 1,000 kg per profile shape per surface finish color. For custom die creation, the initial sample run requires a single die charge (refundable upon achieving annual volume thresholds). Production lead times average 15 to 20 calendar days from sample approval. Transit times via direct container vessels from main shipping hubs to Cát Lái or Hải Phòng port range between 5 to 9 days, providing an exceptionally responsive supply chain for fast-track Vietnamese construction schedules.
All exported aluminum extrusions and sheets undergo export-grade protective packaging. Each individual profile is wrapped with protective PE surface film (custom printed with your logo upon request) or interleaved with non-abrasive kraft paper. Profiles are tied into rigid strapped bundles, reinforced with plastic corner protectors, and packed into steel-banded timber crates or heavy-duty wooden skids designed for forklift loading into 20ft or 40ft HQ container ships. This prevents moisture ingress, friction scratches, and bending during sea transit.
