Product Details
Across the Q5, Q9, 143, Q15, and WT-105B series, these doors share a consistent construction: 6063-T5 thermal break aluminium frames, insulated tempered glass, and a powder coated surface in your chosen brown shade. For the Q15 series, standard colours include Dark Brown and Caramel Brown; other series achieve the target hue through RAL colour matching. Multi-track configurations (2 to 5 tracks) support wide openings with integrated concealed drainage and multi-point locking. Depending on the selected series, wind resistance can reach 5 kPa and water tightness up to 450 Pa, making the doors suitable for exposed façades and coastal regions when specified appropriately.
Product Features
Custom Colour Consistency: Match any project palette using powder coating, wood grain, or RAL-matched brown finishes. Standard Dark Brown and Caramel Brown are available for Q15 without extra matching fees.
Multi-Track Flexibility: 2-track to 5-track systems accommodate wide openings while maintaining smooth sliding and easy access to terraces or patios.
Thermal Performance: Thermal break frames and insulated glass deliver U-Factors as low as 2.3 W/(m²·K), lowering heating and cooling loads in conditioned spaces.
Structural Integrity: Q15 heavy-duty models withstand wind pressures up to 4.5 kPa, handling large spans without deflection under design loads.
Smart Technology Ready: Motorised operation, fingerprint access, and app control integrate into commercial or high-end residential entries; optional backup power maintains continued function.
Single-Source Supply: Frames, glass, hardware, and insect screens are delivered as a complete system, cutting procurement steps for developers and contract glaziers.
Customizable Styles
Glass Packages: Insulated tempered, Low-E, or tinted glass; reflective coatings can be selected to match the brown finish and improve solar control.
Profile & Finish: Powder coated Dark Brown, Caramel Brown, or custom RAL shades; wood grain textures also available for a natural look.
Sash Dimensions: Maximum single sash from 1500 mm (Q5) to 4000 mm wide and 6000 mm high (Q15); dims are adjusted to site measurements.
Track Options: 2-track to 5-track sliding, manual or electric, for patio openings up to multi-slide commercial frontages.
Additional Features: Built-in blinds, insect screens, and concealed drainage integrate without disrupting the frame sightlines.
Hardware Accessories
Stainless Steel Handle: Ergonomic stainless steel pull handles with optional key-lock cylinder match the door finish.
Silent Roller System: Heavy-duty rollers keep panel sliding quiet even under large loads; height adjustment simplifies on-site alignment.
Multi-Point Locking: Multi-point locks engage top, bottom, and middle, critical for ground-level access doors.
Concealed Drainage: Built-in drainage channels prevent water accumulation while preserving a clean frame line.
Electric Drive Option: Motorised drives with anti-pinch sensors and backup power support access-controlled or high-traffic entrances.
Basic Parameters
Performance Item | Available Information | Buyer Notes |

Application Scenarios
Apartment: In compact apartments, these doors open onto a balcony without consuming interior floor space. Thermal break insulation and multi-point locking keep the unit comfortable and secure.
Home Office: A garden studio or home office gains a professional look with brown aluminium sliding doors that let in daylight and provide a wide entry for moving equipment.
Hotel: Guestroom balconies feel more spacious with sliding doors in caramel brown; quiet rollers and robust locks ensure a restful stay with minimal maintenance.
Office Building: Meeting rooms partitioned by brown aluminium sliding doors preserve the open-plan feel while offering acoustic privacy and quick reconfiguration for team spaces.
Outdoor: Covered patios and pool houses benefit from the water-tight track design (up to 450 Pa) and corrosion-resistant finishes, making them a durable choice for semi-exposed areas.
Residential Building: Main entrances or garden access points use multi-point locking and heavy-duty tracks to handle daily traffic while matching the building’s exterior colour scheme.
Exterior: On building façades, PVDF-coated brown aluminium profiles resist fading and require less upkeep; however, wind load and corrosion analyses are recommended for coastal or high-rise installations.
Villa: Oversized openings up to 4 metres wide connect living areas to terraces; wood-grain brown finishes add subtle texture and a natural feel without sacrificing performance.
FAQ
What are brown aluminium sliding doors?
They are a custom finish option across DERCHI’s sliding door collection—Q5, Q9, 143, Q15, and WT-105B. By specifying a brown powder coat or RAL-matched colour, buyers get a consistent look with thermal break aluminium and insulated glass, all built to project dimensions.
Where can they be used?
Common applications include hotel balconies, villa patios, apartment terraces, office partitions, and commercial shopfronts. The brown finish works well with warm-toned architecture.
Can it be customized?
Nearly everything: dimensions, track count (2–5), glass type, hardware, and smart controls can be adjusted. Brown colour is matched via powder coat, wood grain, or RAL. We handle OEM/ODM requests.
What information is needed for a quote?
Let us know the preferred series, rough opening size, glass spec, and the brown RAL number or finish type. Project location and quantity help us work out shipping and pricing.
Can it be used for B2B projects?
Yes, we supply bulk orders to contractors and distributors with FOB/CIF/DDP terms, engineering submittals, and installation guidance.
Are technical documents available?
Shop drawings, test reports for wind, water, air, and thermal performance, plus certifications such as NFRC, CE, or AS2047 can be provided on a project basis.
What should buyers confirm before ordering?
Verify the chosen series’ performance data matches local codes, get written confirmation on warranty terms for glass and hardware, and request physical colour swatches so the brown shade is exactly right.
How are the doors packaged and shipped?
Glass panels are crated, aluminium frames are wrapped, and we offer FOB, CIF, or DDP shipping. Our logistics team works with you on packaging and insurance details.
