Enterprise Strength
Direct-from-Source Precision Fenestration with Zero Tolerance
Manufactured by Guangdong Dejiyoupin Doors and Windows Co., Ltd. (DERCHI) in Foshan, China, our specialized aluminum back door solutions eliminate common failure modes observed in tropical architectural developments. Back doors serve as the vulnerable juncture of the building envelope—exposed to ground-level humidity, forceful wind loads, thermal transmission, and intrusion vectors.
Recognized as a "China Famous Brand" by Xinhua News Agency, DERCHI deploys 360° digital quality control protocols across profile extrusions, multi-point locking gear fitting, and marine-level architectural powder coatings. We ensure compliance with strict international testing regimes including CE, NFRC, AS2047, CSA, and ISO 9001.

Localized Applications
Engineered for Brazil’s Distinct Microclimates & Security Profiles
From saline Atlantic sea-breezes to violent subtropical summer squalls, our systems are adapted to meet structural demands defined by ABNT NBR 10821.
Coastal Marine Defense (Maresia)
The Atlantic coastline subjects rear access openings to constant airborne chlorides. Standard steel or thin aluminum frames pit, oxidize, and seize within 24 months.
- Qualicoat Class 2 fluorocarbon/powder coating (60-80μm)
- SUS316 marine-grade structural hinges and fixings
- EPDM co-extruded perimeter gaskets resisting salt air embrittlement
Perimeter Anti-Intrusion (Segurança)
Rear service entrances, laundry areas, and garden exits are primary target areas for forced entry in high-density metropolitan and suburban villa settings.
- Patented Four-Side Six-Point perimeter latching array
- Concealed anti-pry heavy hinges preventing hinge-pin extraction
- PVB laminated safety glazing (6mm + 1.14PVB + 6mm)
Subtropical Thermal Barrier & HVAC Isolation
High diurnal temperature swings and blazing afternoon solar radiation in Brasília, Goiânia, and Campinas generate extreme envelope stress and massive AC power consumption.
- Multi-chambered PA66 polyamide structural thermal break
- Double-glazed Low-E argon-filled units (Ug ≤ 1.6 W/m²K)
- Thermal expansion compensating subframe anchors
Industry Insights
Architectural Trends Reshaping the Brazilian Door Market
Strategic movements toward energy certification, hurricane-level rainproofing, and minimal profiles are driving supply chain modernization across South America.
Stringent ABNT NBR 10821 Compliance
Engineers and developers increasingly mandate documented wind pressure, water tightness, and air infiltration metrics, rejecting uncertified local profile assembly.
Thermal Break Adoption in Luxury Condos
Driven by LEED and AQUA-HQE green building certifications, thermal break aluminum systems have transitioned from luxury novelties to non-negotiable specifications.
Flush Sill "Piso Nivelado" Transitions
Seamless transition from internal kitchens/gourmet verandas to backyards using sub-surface drainage cascades capable of draining 120 mm/hr tropical rainfall.
Biometric & Smart Perimeter Automation
Back entries now require motorized multipoint auto-deadbolts synchronized with whole-home automation systems for biometric and remote smartphone clearance.

Procurement FAQ
Frequently Asked Questions by Brazilian Contractors & Specifiers
Essential insights covering logistics, anti-corrosion benchmarks, customs compliance, and structural performance.
Q1: How do DERCHI aluminum doors resist coastal oxidation (maresia) in Santos or Florianópolis?
We apply architectural grade polyester powder coatings certified under Qualicoat Class 2 standards (film thickness exceeding 60-80 microns) or Class 1 anodization (20-25 microns). Additionally, all screws, internal lock linkages, and handle pins are manufactured from high-grade 304 or 316 stainless steel, completely eliminating galvanic corrosion caused by humid sea salts.
Q2: Can DERCHI profiles meet Brazilian structural standard ABNT NBR 10821?
Yes. Our engineering division produces FEA (Finite Element Analysis) structural reports calculating inertia moments, deflection limits (L/175 or L/240), and wind-load resistance. Whether supplying a ground-level villa or a 30-story waterfront residential tower, our mullions and door leaf stiles are reinforced to withstand severe localized wind pressure zones up to 4500 Pa.
Q3: What is the standard ocean freight transit and total turnaround time to Brazil?
Manufacturing typically spans 30 to 40 days following CAD shop drawing approval and deposit receipt. Ocean transit from Shenzhen/Guangzhou ports to Brazilian ports (Santos, Paranaguá, Rio de Janeiro, Itajaí, Salvador) ranges between 35 and 48 days. We recommend engineering and order sign-off approximately 90-110 days prior to drywall or subframe readiness on-site.
Q4: How does DERCHI support Brazilian import tariffs and customs clearance (Siscomex)?
We provide full export documentation required by Brazilian customs clearance brokers (Despachantes Aduaneiros). Documents include Commercial Invoices with clear NCM (Mercosul Common Nomenclature) codes, accurate Packing Lists specifying net/gross weights per crated unit, original Bills of Lading (B/L), and Certificates of Origin to ensure seamless clearance through the Siscomex portal.
Q5: What security lock features are incorporated on exterior back doors?
Unlike standard single-latch systems, DERCHI back doors utilize proprietary multi-point locking gear, featuring top, bottom, and lateral mushroom-head shootbolts. Our patented Four-Side Six-Point lock locks the sash firmly into the perimeter frame at six distinct structural contact zones, preventing crowbar prying, sash lifting, or violent impact kicks.
Q6: Can units be delivered fully pre-glazed, or is on-site glazing recommended?
For standard casement and single back doors, we export fully assembled, pre-glazed, and factory-tested units ready for immediate dry installation using perimeter expansion anchors. For extra-large bi-fold or heavy sliding door openings, frames are flat-packed with pre-cut miters and glass units crated separately to ensure safe handling and avoid transport breakage.
