Direct Factory OEM/ODM Architectural Products Engineered for High-End Residential & Commercial Developments Worldwide
Headquartered in Foshan, Guangdong—the capital of China’s premium aluminum extrusion industry—Doorreme Aluminum Industry Co., Ltd. has established itself as an authoritative leader in high-precision architectural aluminum fenestration and custom Aluminium Jali for window systems. Operating out of a massive 123,000 m² state-of-the-art production base, our plant combines European CNC fabrication technology with strict ISO 9001 and CE compliant quality assurance systems.
Architects, real estate developers, and civil engineering contractors often encounter significant structural challenges when specifying decorative metal screens (Jali), security louvers, and thermal-break window systems. Standard off-the-shelf window grills frequently fail to harmonize wind-load resistance with aesthetic perforated ventilation. Our engineering department overcomes this bottleneck through structural silicone glazing (SSG), multi-axis laser cutting technology, and customized extruded 6063-T5 / 6061-T6 aluminum profile matrixes.
Equipped with fully automated double-head cutting saws, 5-axis CNC machining centers, and automated corner-crimping equipment ensuring tolerance accuracy under 0.1mm.
Surface treatments include AkzoNobel fluorocarbon (PVDF) coating and high-durability anodizing engineered to withstand 3,000+ hours of continuous salt spray testing in coastal zones.
From preliminary elevation drawings to wind pressure structural calculations and shop-ready assembly plans, our 800+ team delivers total technical transparency.
In modern architectural design—spanning Mediterranean luxury villas, Middle Eastern residential projects, and tropical high-rises—the traditional stone or timber Jali (perforated lattice screen) has evolved into engineered Aluminium Jali systems. Unlike organic materials that warp, corrode, or degrade under UV radiation, aluminum lattice grilles provide exceptional structural integrity, security defense, light diffusion, and passive cross-ventilation.
To assist procurement managers, facade consultants, and structural engineers in specifying the correct grade, the table below details our standard manufacturing parameters compared to generic market alternatives:
| Engineering Property | Doorreme Premium Aluminium Jali Standard | Standard Commercial Grade | Engineering Benefit |
|---|---|---|---|
| Alloy Grade | 6063-T5 / 6061-T6 Architectural Profile | 6063-T4 / Recycled Scrap Alloy | Higher tensile strength (≥205 MPa), crack-free laser cutting |
| Profile Thickness | 1.4mm – 3.0mm Heavy-Duty Custom Extrusion | 0.8mm – 1.2mm Thin-wall sheet | Zero frame distortion under high wind pressure (Up to 4.5 kPa) |
| Surface Treatment | PVDF Fluorocarbon Spraying / Electrophoresis | Basic Powder Coating | 20+ Years color retention; anti-fade against extreme UV & rain |
| Security Wire Mesh (Flynet) | 304 / 316 Marine-Grade Stainless Steel (0.8mm wire) | 201 Stainless Steel or Fiberglass | Anti-burglary bulletproof mesh screen integrated into Jali frame |
| Thermal Insulation (U-Value) | U ≤ 1.6 - 2.2 W/m²·K (With PA66 Thermal Break) | U ≥ 3.8 W/m²·K (Non-thermal break) | Reduces HVAC cooling power consumption by up to 35% |
| Acoustic Insulation | Double Glazed (5+20A+5) + Jali: Sound Reduction 38-42 dB | Single Glass: Sound Reduction < 22 dB | Superior noise attenuation for urban highway residential projects |
As global building energy codes tighten across North America, the Middle East, Southeast Asia, and Europe, the architectural fenestration sector is experiencing significant technological shifts. Understanding these emerging trends allows developers to future-proof their building projects while optimizing lifecycle procurement costs.
Automated roll-up and bi-folding micro-perforated aluminum shutters are rapidly replacing manual security grills. These smart facade components interface with home automation platforms, automatically adjusting perforation angles based on solar radiation angles and wind velocity.
Minimalist luxury architecture demands unobstructed views without compromising security. Modern designs integrate high-tensile stainless steel security Jali screens directly inside slim-frame aluminum casement profiles, offering invisible structural protection.
Global ESG benchmarks require building material manufacturers to reduce embodied carbon. Doorreme utilizes low-carbon aluminum billets extruded using clean hydropower energy, supporting LEED and BREEAM green building certifications.
Direct Answers to Critical Sourcing Questions Asked by Overseas Real Estate Developers, General Contractors, and Importers
Every single unit is fabricated strictly to custom shop drawings. Once structural opening measurements or CAD blueprints are submitted by your team, our senior engineering department generates 2D cross-section elevations and 3D BIM models detailing glass specs, hardware placements, drain hole positions, and anchoring flanges. Mass production begins only after receiving your formal signed approval on production drawings.
Aluminium Jali offers several major advantages over traditional iron or mild steel window grills:
1. Corrosion & Rust Resistance: Aluminum naturally forms a protective oxide layer and, when finished with PVDF or anodizing, will never rust, peel, or stain building facades—even in high-humidity coastal salt air.
2. Weight & Load Reduction: Aluminum is approximately one-third the weight of steel, significantly reducing dead-load pressure on structural cantilevers and window frames.
3. Design Versatility: High-precision CNC laser cutting enables complex geometric, Islamic, floral, or abstract architectural patterns that are cost-prohibitive to hand-weld in iron.
Yes. We manufacture heavy-duty hurricane-impact window series specifically engineered for coastal storm zones like Florida (USA), the Caribbean islands, and typhoon-prone Pacific regions. Our impact-rated systems combine reinforced 6061-T6 aluminum profiles with PVB/SGP laminated safety glass (e.g., 5mm + 1.52SGP + 5mm) and multi-point German locking hardware, passing strict wind pressure and debris-impact benchmarks.
We provide a comprehensive range of architectural finishes:
• PVDF Fluorocarbon Coating: Recommended for exterior facades and coastal areas, backed by a 15–20 year non-fading guarantee.
• Qualicoat Powder Coating: Extensive RAL color choices with exceptional scratch resistance.
• Architectural Anodizing: Silver, Champagne, Bronze, and Black metallic effects highlighting natural aluminum texture.
• 3D Wood-Grain Transfer: Delivers the warm visual appeal of natural timber without rotting, warping, or maintenance demands.
Standard production lead time ranges between 25 to 35 business days following drawing sign-off and deposit receipt. For export freight safety, all items undergo a 4-layer protective packaging sequence: protective film layer + EPE foam wrapping + tough corner guards + fully enclosed fumigated plywood crates. This guarantees zero scratching or frame deformation during oceanic container transport.
Yes. For major commercial developments, resort complexes, and high-rise curtain wall projects, Doorreme can dispatch experienced structural technical directors and field engineers directly to your job site to oversee installation sequencing, structural anchor checks, and water-tightness testing. We also provide step-by-step 3D installation manuals and video tutorials for local construction crews.
