What is the minimum order quantity for aluminum windows and doors?

Because every unit is made to measure, VELTOR accepts single-project orders as well as container-load dealer orders. The practical minimum is usually defined by shipping economics, so we help buyers consolidate windows and doors into one shipment.

Do you offer thermal break aluminum windows for cold climates?

Yes. Our thermal-break systems use polyamide insulating strips combined with double or triple insulated glass units, Low-E coatings and warm-edge spacers. Final thermal performance depends on the system series and glass build-up chosen for your climate zone.

Can you manufacture to my local building standards?

We engineer each project against the buyer's target standards for wind load, water tightness, air permeability and safety glazing, and provide the related documentation for review before production.

How are windows and doors packed for export?

Frames are protected with film and corner guards, glass units are separated, and finished products are loaded in reinforced wooden crates labeled by opening number to simplify on-site installation.

What is the typical production lead time?

Lead time depends on order size, finish and glass specification. After drawings are confirmed and the deposit is received, we issue a written production schedule so buyers can plan shipping and installation.

Structural Dynamics & OEM Manufacturing Specs of Vertical Aluminium Doors

Understanding kinetic weight balancing, motorized counterweights, thermal break geometry, and hurricane-impact ratings in vertical bi-fold and vertical sliding entry systems.

Architectural Kinetic Balancing

Custom vertical aluminium doors rely on precise load balance mechanisms. Utilizing counterweight pulley systems or heavy-duty tubular linear actuators, vertical lifting doors allow massive glass spans up to 6 meters wide to open vertically with minimal friction and whisper-quiet motor operation.

Thermal Break Insulation Mechanics

Our extrusion lines utilize engineered PA66-GF25 (Polyamide 66 reinforced with 25% glass fiber) insulation bars. Combined with Argon-filled double or triple insulated glass units (IGU) featuring Low-Emissivity coatings, overall U-values drop to below 1.4 W/m²K for extreme climate compliance.

Weather Sealing & Water Tightness

Vertical movement introduces distinct water management challenges. We incorporate continuous dual-component EPDM gaskets paired with hidden internal drainage channels, achieving design pressures rated up to DP70 (330 Pa water resistance) under ASTM E331 test standards.

Door System Type	Kinetic Motion	Structural Wind Load Resistance	Acoustic Rating (STC)	Ideal Architectural Application
Vertical Bi-Fold Aluminium Door	Motorized / Counterweight Folding	DP50 – DP70 (Up to 3,500 Pa)	STC 38 – 42 dB	Luxury Residential Patios, Commercial Restaurants, Rooftop Lounges

We assist dealers, contractors, and project developers with official product documentation including CE (EN 14351-1), NFRC energy ratings, Australian AS2047, and SGCC glass safety certificates.

Industry Insights

Future Sourcing & Product Development Trends in Vertical Fenestration

Macro analysis of architectural design shifts, smart automation integration, and sustainable supply chain dynamics for B2B door and window buyers.

1. Smart Building Integration (BMS Automated Vertical Systems)

Modern architectural projects demand seamless integration between vertical opening systems and centralized Building Management Systems (BMS). Procurement trends indicate an 80% increase in requests for motorized vertical bi-fold doors equipped with smart rain sensors, wind speed safety retractors, obstacle-detection infrared safety edges, and mobile app connectivity.

2. Ultra-Slim Sightlines with Maximum Structural Glass Ratios

Architects are replacing heavy structural frames with minimal frame profiles. Breakthroughs in high-tensile 6063-T6 aluminum alloys allow profile face widths as slim as 25mm to support vertical glass panels weighing over 350kg without flexure or structural displacement under wind loads.

3. Low-Carbon Recycled Aluminium & Environmental Transparency

Global real estate developers are prioritizing LEED and BREEAM green building certifications. OEM manufacturers using primary aluminum produced via renewable hydro-power (reducing carbon intensity to under 4.0 kg CO2e/kg Al) are rapidly capturing high-end commercial export markets.

4. Direct OEM Factory Collaboration & BIM/CAD Standardization

The traditional multi-tier distribution network is being bypassed. Global project builders are directly collaborating with primary Foshan manufacturers to obtain native Revit BIM objects, parametric CAD shop drawings, and tailored custom extrusion tooling directly from factory engineers.

Procurement FAQ

Frequently Asked Questions for Custom OEM Vertical Door Procurement

Key technical and logistical queries addressed by our Senior Engineering Director.

What structural calculations are required before customizing a vertical aluminium door?

Custom vertical door manufacturing requires analyzing structural wind load (DP rating), total dead-load weight of the double/triple glazed glass units, overhead beam load bearing capacity, and electrical actuator torque requirements. Our engineering team provides detailed Finite Element Analysis (FEA) and CAD shop drawings for architect approval prior to tooling production.

How do vertical aluminium bi-fold doors perform against severe hurricane force winds?

When engineered with multi-point stainless steel locking pins, heavy-duty interlocks, and laminated impact glass (PVB or SGP interlayers), our thermal break vertical bi-fold doors meet Florida Product Approval and High-Velocity Hurricane Zone (HVHZ) requirements, standing up to design pressure wind loads exceeding +50/-50 PSF.

What is the Minimum Order Quantity (MOQ) for custom OEM profile colors and extrusions?

For standard anodized, fluorocarbon PVDF, or powder-coated finishes (such as Matte Black, Architectural Bronze, or Charcoal Gray), we accept single-project custom orders (as low as 1 container load or multi-unit villa orders). For proprietary custom profile die extrusions, die tooling setup fees apply, which are refundable once order volume reaches specified metric tonnage thresholds.

How are motorized vertical lifting doors safely operated in commercial environments?

Safety is paramount for vertical movement. Our systems incorporate triple-layer redundancy: (1) Dual anti-drop safety brakes that instantly lock the pulley system if cable tension drops; (2) Bottom edge optical contact sensors that instantly stop and reverse movement if an obstacle is detected; and (3) Constant-pressure deadman control switches or keypads.

What lead times can international builders expect for export orders?

Standard manufacturing turnaround is typically 25 to 35 calendar days following shop drawing sign-off and glass spec confirmation. For complex motorized vertical door systems requiring custom color anodizing or specialized SGP impact glass, lead times range between 35 and 45 days, supported by direct sea freight container loading from Shenzhen/Guangzhou ports.

How are finished doors packaged to prevent damage during ocean transit?

Frames are wrapped in protective scratch-resistant film and fitted with rigid corner guards. Fully assembled sashes and insulated glass units are packed into IPPC-certified fumigated solid wooden crates, secured with steel banding, and cushioned with shock-absorbing EPE foam blocks.
