Why Source Wholesale Aluminium Security Doors from China?
An executive procurement breakdown of physical structural integrity, thermal barrier engineering, and multi-locking hardware integration.
Multi-Point Gearbox Security Locking
Unlike standard single-latch residential doors, our structural security doors utilize multi-point gearboxes (5 to 9 locking points along the jamb, head, and sill). Constructed from hardened SUS304 stainless steel, these hooks and deadbolts resist heavy crowbar leverage up to 10,000 N of force.
PA66 Polyamide Thermal Break Strips
Security doors often suffer from thermal bridging. We integrate 24mm to 34mm German-engineered PA66GF25 (25% glass fiber reinforced polyamide) thermal break strips. This separates the exterior and interior extruded aluminum frames, reducing U-values to below 1.4 W/m²K while eliminating condensation.
Qualicoat Class 2 Fluorocarbon Coating
Exterior aluminum surfaces are subjected to coastal salt spray and severe UV degradation. Our in-house automated powder coating line uses PPG and AkzoNobel PVDF fluorocarbon coatings, tested to withstand 3,000+ hours of continuous salt-spray testing without chalking or peeling.
Precision CNC Corner Crimping
Frame joint failure is the leading cause of water leakage and structural sagging. Veltor utilizes double-head CNC saws combined with heavy pneumatic corner crimping machines and injected two-component polyurethane corner adhesives, guaranteeing air-tight and water-tight frame joints.
Laminated Security Glazing (SGCC / AS2208)
Glass-fitted security doors incorporate double-glazed insulated units with PVB or SGP (SentryGlas) laminated safety glass. SGP interlayers provide 5x the tear strength and 10x the stiffness of conventional PVB, maintaining structural integrity even when fractured by impact.
OEM & Private Label Manufacturing
We partner with international fenestration brands, project dealers, and commercial real estate developers. Offerings include fully customized extrusions, custom hardware stamping, specialized export timber crating, and BIM/CAD shop drawing support.

Frequently Asked Questions for Wholesale B2B Sourcing
Direct technical answers from Veltor’s engineering team regarding minimum order quantities, shipping logistics, structural testing, and warranty terms.
What is the Minimum Order Quantity (MOQ) for wholesale custom aluminum security doors?
Because every structural door unit is custom-manufactured according to architectural shop drawings, Veltor accommodates flexible ordering models. For project-based contractors and builders, our standard MOQ is 10 units or consolidated container mix-loads. For wholesale distributors establishing OEM private-label production, the recommended batch size is one 20ft container (approx. 60–80 door units) to maximize shipping freight efficiency.
How do Chinese aluminum security door manufacturers ensure burglary protection standards?
High-grade aluminum security doors rely on three structural pillars: high-tensile 6063-T6 alloy profiles with minimum wall thickness of 2.0mm to 3.0mm, internal steel reinforcements, and multi-point lock hardware. At Veltor, our security doors undergo static loading, dynamic impact, and manual burglary resistance testing matching European EN 1627 standards up to RC3 and RC4 levels, preventing forced entry via crowbars, drills, and mechanical cutters.
Can aluminum security doors achieve effective thermal insulation in freezing climates?
Yes. Uninsulated aluminum is thermally conductive, but modern security doors engineered with polyamide thermal break systems (PA66GF25) decouple the inner and outer metal frames. Combined with double or triple-glazed Low-E argon gas-filled glass units, warm-edge spacers, and multi-layer weatherstripping, our systems achieve overall U-factors as low as 0.18 to 0.28 BTU/h·ft²·°F (1.0 to 1.6 W/m²K), meeting stringent North American NFRC and European Passive House requirements.
What structural glass specifications are used in glazed security entry doors?
For glazed security doors, standard tempered glass is insufficient against violent break-ins. We specify laminated safety glass configurations using SentryGlas® (SGP) or high-density PVB interlayers (e.g., 6mm Toughened + 1.52SGP + 6mm Toughened). SGP laminates stay stiff and intact even under extreme force, blast pressures, or hurricane-force wind impacts up to 5,000 Pascals (AS2047 / ASTM E1300 compliant).
How are doors protected against corrosion in coastal salt-air environments?
For coastal project locations, standard powder coating will pit and peel. We utilize pre-anodized surface pretreatments followed by Qualicoat Class 2 or Class 3 Fluorocarbon (PVDF) spray coatings. Furthermore, all exposed structural hardware, hinges, handle sets, and lock gearboxes are upgraded to marine-grade SUS316 stainless steel to ensure zero corrosion over a 15-year operational lifecycle.
What is the typical production lead time and export packaging method?
Once shop drawings are signed off and deposit confirmed, production takes approximately 25 to 35 calendar days depending on hardware complexity. For export packing, each door frame and sash is wrapped in protective PE anti-scratch film, corner-guarded with high-density foam, and packed inside fully enclosed, fumigated ISPM-15 compliant plywood crates to guarantee zero transit damage during sea freight.
