Direct from Guangdong Dejiyoupin Doors and Windows Co., Ltd. (DERCHI), our architectural assemblies feature extruded primary 6063-T6 virgin aluminium alloys, multi-point lock mechanisms, and high-performance weather sealing tailored for Brazil's demanding coastal, urban, and luxury interior projects.
For Brazilian architects, general contractors (construtoras), and project developers, sourcing imported aluminium swing door assemblies requires rigorous compliance verification. While the European CE Mark (under EN 14351-1:2006+A2:2016) establishes exhaustive testing metrics for air permeability, water tightness, wind resistance, and structural safety, it also directly maps to Brazil’s stringent ABNT NBR 10821 (Building Façade Openings) and the multi-attribute performance code ABNT NBR 15575 (Edificações Habitacionais — Desempenho).

Brazil’s diverse bioclimatic zones—ranging from aggressive marine coastal environments to bustling dense metropolises and humid tropical interiors—require specialized architectural fenestration configurations. DERCHI's CE-certified aluminium swing doors are engineered to conquer these regional physical challenges.
São Paulo, Campinas & Alphaville: High-end residential villas prioritize architectural grandeur and perimeter security. Our oversized swing doors feature concealed 3D adjustable pivot hinges, supporting sashes up to 300kg, paired with 5-point burglar-resistant multipoint locking mechanisms and integrated biometric access control compatible with Brazilian smart-home platforms.
Santos, Balneário Camboriú & Recife: Exposure to marine atmosphere (Atmospheric Corrosivity Category C4/C5 per ISO 12944) causes standard fittings to seize and powder coatings to blister. DERCHI provides Seaside-grade pre-treatment with 25µm architectural anodizing or fluorocarbon (PVDF) finishes, utilizing AISI 316 marine-grade stainless hardware.
Avenida Paulista & Faria Lima (SP): Dense urban traffic noise frequently exceeds 75 dBA. Our thermal-break aluminium swing door systems utilize asymmetric acoustic laminated glass (e.g., 6mm float + 0.76mm acoustic PVB + 6mm float) with magnetic threshold compression seals, achieving Rw ratings exceeding 40 dB in accordance with NBR 15575 acoustic requirements.
Hotels, Shopping Centers & Clinics: Projects in Rio de Janeiro and Curitiba require barrier-free accessibility compliant with ABNT NBR 9050. DERCHI integrates ultra-low recessed thermal threshold systems (less than 15mm elevation) with heavy-duty overhead concealed closers and anti-finger trap rounded pivot stiles for safe public egress.
The structural vulnerability of standard swing doors in tropical storm zones often lies in the sash corner joints and sill seals. DERCHI solves this with an industrial-grade internal jointing system:
The civil construction industry in Brazil is undergoing a structural transformation toward sustainable building materials, stricter building codes, and accelerated supply-chain digitalization. Importers and developers who align with these macroeconomic trends gain a decisive competitive edge.
Brazilian tier-one developers (such as Cyrela, JHSF, and Multiplan) increasingly mandate green building credentials. The demand for thermal-break aluminium swing doors with verified low solar heat gain coefficients (SHGC) and low thermal transmittance (U-value) has surged by over 35% year-on-year to score essential energy conservation credits under the PROCEL Edifica rating scheme.
Architectural taste in Brazilian luxury residential design has pivoted sharply away from bulky conventional profiles toward ultra-slim, minimalist frames with fully concealed hinges and flush architectural thresholds. Architects demand maximum visual glass surface area while retaining structural rigidity capable of resisting high coastal wind loads.
Domestic Brazilian extrusion extruders and fabricators often struggle with multi-month delivery backlogs, limited custom powder coat choices, and elevated domestic metal processing markups. Forward-thinking Brazilian contractors increasingly establish direct B2B supply lines with large-scale Chinese certified manufacturers, realizing 20% to 35% net landed cost efficiencies even factoring import duties (II/IPI) and maritime freight.
Guangdong Dejiyoupin Doors and Windows Co., Ltd. (operating the DERCHI brand) represents the highest echelon of China’s intelligent fenestration manufacturing. Ranked among the Top 10 Door & Window Brands in China, our infrastructure guarantees scale, engineering precision, and full international certification integrity.
Equipped with German CNC 4-axis profile machining centers, automated computerized sawing lines, and Italian dual-component crimping systems, DERCHI achieves 0.1mm dimensional tolerance across custom door schedules of any magnitude.
Our dedicated bilingual engineering team generates full shop drawings, BIM families, elevation schematics, and structural calculation reports free of charge, allowing Brazilian engineering consultants to approve specs without friction.
Every swing door assembly is sealed in heavy moisture-barrier plastic film, cushioned with multi-layer high-density EPE foam, and encased within fumigated solid plywood crates. We provide precision container loading layouts to maximize container cube utilization for lower freight costs to Santos or Paranaguá.
Clear, definitive technical answers addressing customs classification, standard equivalence, protective packaging, and logistics to Latin America’s largest economy.
Under Brazilian standard ABNT NBR 10821, third-party accredited laboratory test reports are mandatory. European CE certification under EN 14351-1 tests the identical physical parameters (dynamic air infiltration, static water penetration, and uniform wind load). DERCHI provides full English test reports and ISO 9001 compliance documentation that Brazilian municipal bodies and engineering consultants readily recognize.
Aluminium doors and windows typically clear Brazilian customs under NCM 7610.10.00 (Portas, janelas e seus caixilhos, alizares e soleiras, de alumínio). DERCHI provides accurate commercial invoices, detailed packing lists with net/gross weights, and Certificate of Origin (CO) documentation to streamline your clearing agent’s RADAR Siscomex import declaration process.
Transoceanic shipment through equatorial waters exposes cargo to humidity and swell vibration. Each door panel and frame is wrapped in electrostatic protective film, corner-guarded with cellular foam, and crated inside individual IPPC-certified fumigated plywood boxes. We include industrial desiccant bags within each package to actively eliminate condensation damage.
We routinely export directly to major Brazilian maritime terminals including Porto de Santos (SP), Porto de Paranaguá (PR), Porto de Itajaí / Navegantes (SC), Porto de Suape (PE), and Porto do Rio de Janeiro (RJ). We offer flexible Incoterms including FOB Foshan/Shenzhen or CIF Brazilian base ports.
Yes. We offer Italian sublimation vacuum heat-transfer wood-grain finishes as well as Qualicoat Class 2 hyper-durable textured powder coatings (AkzoNobel / Tiger). These formulations withstand intense ultraviolet radiation in northeastern and central Brazil without chalking, fading, or peeling for over 15 years.
Standard lead times for bespoke aluminium swing doors and matching window systems range between 25 and 35 calendar days following formal CAD sign-off and deposit receipt. For complex anodized finishes or bullet-resistant composite entries, allow 35 to 40 days. We provide photographic progress reports at cutting, assembly, and test-hang stages.
Whether you are developing a luxury residential condominium in São Paulo, a beachfront resort in Bahia, or importing container-load fenestration products for local Brazilian distribution, our engineering team is ready to draft your complimentary CAD shop drawings and prepare competitive FOB/CIF quotation matrices.
