Direct factory production from Guangdong Dejiyoupin (DERCHI) with European test standards, multi-point locking mechanisms, and bespoke structural sizing for the Spanish building sector.
Navigating climatic zones A through E with poliamida thermal breaks, Guardian Sun low-emissivity glass, and acoustic performance targeted for urban and coastal Spain.
Spain presents one of Europe’s most diverse microclimatic challenges for fenestration engineering. From the extreme marine salinity and intense solar radiation along the Costa del Sol and the Balearic Islands (Zone A/B) to the stringent sub-zero winter thermal thresholds of Madrid and Castile-León (Zone D/E), specifying glazed aluminum swing doors (puertas batientes de aluminio y vidrio) requires comprehensive technical alignment with the Código Técnico de la Edificación (CTE), specifically Documento Básico HE (Ahorro de Energía) and DB-HS (Salubridad).
As a Tier-1 global fenestration manufacturer with over 25 years of specialized metallurgical and glazing craftsmanship, Guangdong Dejiyoupin Doors and Windows Co., Ltd. (operating the international brand DERCHI) engineers aluminum glass swing systems designed to surpass the rigorous thermal transmittance (Uw values down to 1.1 W/m²K) and air permeability standards (Class 4 according to UNE-EN 12207) required for Spain's luxury residential and commercial developments.
Modern Spanish architecture favors minimal sightlines without sacrificing structural stability against wind loads (UNE-EN 12210 Class C5). Our engineered swing doors utilize primary extruded aluminum alloy 6063-T6 with a profile wall thickness of 2.0mm to 3.0mm. Profiles undergo multi-stage chromate-free chemical pre-treatment followed by European architectural powder coating adhering strictly to Qualicoat Class 2 (Seaside endorsement) and Qualanod specifications. This provides decisive protection against filiform corrosion in high-salinity zones such as Marbella, Alicante, Valencia, and Palma de Mallorca.

Customized structural engineering tailored to Spain's distinctive regional architectural typologies, climatic exposures, and urban development standards.
High-exposure sea frontage along Marbella, Ibiza, and Mallorca subjects exterior swing doors to persistent salt fog, heavy UV irradiation, and sudden Mediterranean squalls. Systems must withstand saline oxidation while maximizing natural panoramic vistas.
Continental climates experience acute thermal swings exceeding 40°C in July and plunging below freezing in January. Spanish CTE Zone D/E demands advanced thermal break systems (Rotura de Puente Térmico) to curb heating/cooling loads and prevent internal condensation.
Renovating classic turn-of-the-century heritage apartments in Barcelona, Valencia, and Bilbao requires preserving traditional slim sightlines while meeting contemporary DB-HR acoustic insulation requirements against heavy street and nightlife noise.
Key sustainability directives, minimalist aesthetic expectations, and smart building integration transforming Iberian door procurement.
Architects across Catalonia, Madrid, and the Basque Country increasingly demand green certifications such as BREEAM ES and LEED v4. DERCHI integrates hydro-powered low-carbon aluminum scrap and closed-loop recyclability into primary billet extrusion lines.
Traditional protruding butt hinges are rapidly giving way to 3D adjustable 180° concealed barrel hinges and flush coplanar leaf profiles. Spanish developers prioritize unobstructed glass expanses and clean geometric lines.
Integration with European smart home protocols (KNX, Somfy, Zigbee). Smart motorized locks featuring encrypted biometric scanners, numeric passkeys, and remote smartphone control are now standard in upscale Spanish single-family developments.
With updates to the Energy Performance of Buildings Directive (EPBD), Net-Zero Energy Buildings (nZEB) demand airtightness Class 4 and overall frame values that practically eliminate thermal bridges in northern Atlantic climate zones.
Empowering Spanish importers, construction contractors, and architects with factory-direct precision, certified quality control, and seamless containerized shipping.
Backed by over 25 years of specialized manufacturing experience, DERCHI operates an intelligent production facility spanning 180,000 square meters in Foshan, Guangdong. Equipped with CNC automated cutting centers, computerized thermal break insertion stations, and specialized cleanroom insulating glass lines, we produce architectural swing doors with micrometer precision.
For Spanish contractors and builders, DERCHI eliminates intermediary markups by offering direct-from-factory FOB or CIF pricing directly to Spain's primary ports: Valencia, Barcelona, Algeciras, and Bilbao. Every door order undergoes full pre-assembly, laser dimension validation, and airtightness testing before receiving custom fumigated plywood crating engineered for maritime export.
A transparent, risk-free manufacturing and delivery process refined across thousands of European and international commercial shipments.
Submit architectural door schedules, CTE performance goals, glass types, and RAL color references to our technical sales team.
Our engineering department generates detailed 2D/3D fabrication drawings, verifying swing directions, rebates, thresholds, and clearances.
High-precision profile CNC miter cutting, polyamide crimping, corner crimping with two-component adhesive, and multi-point hardware installation.
Each swing door undergoes factory dry-hang inspection, protective film wrapping, corner guards, and fully sealed fumigated timber box packaging.
Full container load (FCL) or less-than-container load (LCL) shipping directly to Valencia, Barcelona, Algeciras, or Bilbao with complete customs dossiers (Bill of Lading, CE DoP, packing lists).
