Factory Capabilities Dedicated to High-Volume Indian Procurement
Operating as Guangdong Dejiyoupin Doors and Windows Co., Ltd. (DERCHI), our infrastructure integrates European robotic extrusion lines, advanced CNC milling, and high-efficiency sandblasting to provide unmatched manufacturing repeatability for major builders.
End-to-End OEM/ODM Flexibility
From customized wall thicknesses (1.4mm to 3.0mm primary alloys) to non-standard structural spans, our drafting office translates structural consultant schedules into millimetric-precision CAD and BIM models with zero deviation.
Marine-Grade Powder & PVDF
Treated with AkzoNobel and PPG fluorocarbon finishes passing 3,000+ hours of continuous salt-spray testing. Profiles resist the intense oxidative degradation typical of Indian coastal environments such as Mumbai and Chennai.
Proprietary Frosting & Ceramic Fritting
Equipped with acid-etching, automated quartz sandblasting, and ceramic digital fritting lines that deliver flawless light transmission with high visual opacity—preventing staining, grease buildup, and chemical discoloration.
Export-Crated Logistics Security
Every panel is individually wrapped with protective PE film, corners braced with high-density EVA shock-buffers, and boxed into fumigated solid plywood cases engineered to withstand maritime friction across long sea routes.
Certified Global Compliance
Our assemblies carry international certifications including CE, ISO9001, AS2047, and UL fire-rating tests, allowing Indian structural engineers and facade consultants to satisfy stringent local municipal building codes effortlessly.
Dedicated Engineering Desk
Our engineering support team coordinates across Indian standard working hours (IST), offering on-call live technical reviews, factory VR inspections, and live hardware operation audits directly with your site engineering supervisors.
Targeted Architectural Deployments
Localized Applications Across the Indian Subcontinent
Evaluating spatial utility, acoustic demands, and environmental factors across Tier-1 and Tier-2 Indian development microclimates.
High-Rise Balconies & Wet Areas
Engineered for extreme coastal monsoons and high saline air. Our multi-point sealed sliding frosted doors protect internal luxury interiors from moisture seepage while maintaining absolute privacy on dense residential high-rise elevations.
IT Parks & Corporate Campuses
Deploying acoustic-dampened frosted glass aluminum casements for conference rooms, executive suites, and collaborative co-working layouts. Provides 38dB+ noise reduction alongside diffuse daylight dispersion to reduce artificial cooling loads.
High-End Residential Farmhouses
Thermal break aluminum profiles paired with double-glazed frosted glass panels prevent heat ingress during 45°C+ summer heatwaves and seal tightly against particulate matter and smog throughout winter months.
Boutique Resorts & Spas
Seamless bifold and heavy-duty sliding frosted glass systems establish private, light-filled bathroom transitions, outdoor-to-indoor spa partitions, and private plunge pool entrances with smooth soft-close mechanics.
Strategic Procurement Intelligence
Emerging Fenestration Trends in the Indian Real Estate Sector
The Indian architectural landscape is witnessing an aggressive shift from conventional site-fabricated ironmongery and timber toward pre-engineered, factory-finished aluminum fenestration assemblies.
Transition from Timber to Recyclable Alloy
With escalating timber procurement restrictions and insect-related damage across tropical zones, Grade 6063-T5/T6 architectural aluminum has become the gold standard. It offers lifetime dimensional integrity without warping, swelling, or water rot.
Demand for High-STC Acoustic Performance
Urban densification in metros like Mumbai, Bengaluru, and Pune has elevated sound transmission class (STC) ratings into a core specification requirement. Double-glazed frosted assemblies isolate traffic noise up to 42 decibels.
Pre-Engineered Complete Unit Shipping
Developers are rejecting on-site profile fabrication due to erratic tolerances and poor finishes. OEM factory deliveries—complete with precut frames, pre-milled hardware slots, and certified tempered glass—slash on-site installation timelines by up to 65%.
| Performance Criterion | DERCHI OEM Aluminum Frosted Unit | Local Indian Unbranded Fabrications | Conventional Solid Teak / Flush Wood |
|---|---|---|---|
| Alloy Metallurgy | Virgin 6063-T5 High-Purity Ingot | Recycled, secondary scraps with structural porosity | Organic timber composite |
| Surface Protection | AkzoNobel Marine-Grade Powder (60-80μm) | Manual spray enamel / thin anodizing (<15μm) | Oil/Melamine polish prone to moisture peeling |
| Moisture & Termite Shield | 100% Impervious to water, fungus & insects | Gasket gaps allow internal chamber water stagnation | Vulnerable to swelling, rot, and termite hollows |
| Glass Safety Standards | Certified EN 12150-1 Tempered / Laminated | Annealed or uncertified locally etched sheets | Non-translucent solid cores |
| Air & Water Ingress Seal | Automated Co-Extruded EPDM Gaskets | Standard PVC strips that embrittle under heat | Brushed edge seals with poor hermetic isolation |

Procurement FAQs for Indian Contractors & Architects
Transparent, practical technical answers addressing ocean logistics, port clearance, custom CAD layouts, and on-site assembly across India.
What are the shipping routes, lead times, and ports serviced for deliveries across India?
We routinely dispatch consolidated Full Container Load (FCL) and Less than Container Load (LCL) shipments directly from Nansha or Shenzhen ports to major Indian sea hubs, including Nhava Sheva (JNPT Mumbai), Chennai Port, Mundra Port, and Cochin Port. Transit times range from 14 to 21 sea days depending on routing. Our dedicated export documentation team provides accurate HS Codes (primarily under Chapter 7610 for aluminum structures), Certificates of Origin, commercial invoices, and packing lists formatted specifically for Indian custom broker clearing.
How does your factory prevent the glass frosting from fingerprint staining and environmental discoloration?
Unlike cheap unbranded workshops that use topical spray coatings or adhesive vinyl films—which bubble and peel in India's humid, tropical climates—our facilities utilize genuine chemical acid-etching and high-pressure automated quartz sandblasting followed by an organic nano-sealing bake. This molecular process alters the outer glass surface permanently, delivering smooth, non-porous light diffusion that resists oil stains, hard water marks, and atmospheric dust accumulation.
Can your profiles withstand intense coastal humidity and the harsh monsoons of coastal cities like Mumbai and Chennai?
Yes. For coastal residential and commercial builds, we specify certified AkzoNobel or PPG Interpon D2525 powder coatings or multi-layer PVDF fluorocarbon coatings. These meet AAMA 2604/2605 specifications, withstanding accelerated salt-spray corrosion tests exceeding 3,000 hours without bubbling, chalking, or delamination. Profiles feature dedicated internal multi-cavity drainage chambers with integrated non-return valves to vent monsoon downpours quickly without inward overflow.
Do you accommodate custom architectural opening dimensions, or are orders restricted to modular sizes?
We are primarily an OEM/ODM high-specification factory. Every project schedule is custom-engineered to your architectural opening schedules. Following receipt of your structural drawings, our senior engineering office creates fabrication shop drawings, wind-load cross-sectional calculations, and profile extrusion cross-sections for formal sign-off before manufacturing starts.
How are oversized aluminum frosted doors protected against breakage during transcontinental transit?
Our multi-tier protective packaging system exceeds standard ocean freight requirements. Glass surfaces receive peelable 0.08mm electrostatic surface wrap. Outer perimeter extrusions are fitted with custom shock-absorbent composite corner guards, sealed in high-density polyethylene moisture sleeves, and loaded into custom-built, fully enclosed, IPPC-certified fumigated marine plywood crates secured with internal heavy-gauge steel tie-downs.
What hardware brands, locks, and acoustic gaskets are integrated into your door assemblies?
We integrate world-class hardware packages, including German Siegenia, Hoppe, GU, and Italian Giesse, as well as vetted high-cycle Chinese commercial hardware including Kinlong and CMECH. Gaskets utilize vulcanized automotive-grade EPDM foam-rubber profiles that maintain elasticity across extreme thermal differentials, providing acoustic attenuation up to 42dB and sealing against external dust and humidity.
