Aluminum Sliding Door For Coastal Buildings from DERCHI is a high-performance sliding door system engineered for salt-laden, high-wind marine environments. Designed for project-based supply to developers, contractors, and distributors, this solution combines corrosion-resistant aluminum construction with large glass panels to create open, weather-tight building envelopes.
- Corrosion resistance via PVDF/anodized coatings and 304 stainless steel hardware
- Multiple series cover diverse wind zones and project scales
- Custom dimensions, glass, and hardware for B2B projects
Product Details
The Aluminum Sliding Door For Coastal Buildings solution uses thermally broken 6063-T5 aluminum frames, double tempered insulated glass (5+27A+5 or 8+21+8), and multi-point locking hardware. Profiles range from 2.0 mm to 6.0 mm thickness, enabling sash sizes up to 3000 mm wide and 4000 mm high. Concealed drainage, EPDM gaskets, and siliconized brush seals resist water penetration even in driving rain.
Unlike ordinary sliding doors, this coastal-grade system tackles salt spray corrosion through PVDF or anodized surface treatments and 304 stainless steel components. Wind load performance reaches 4.5 kPa or Grade 9, while thermal transmittance as low as 2.3 W/m²·K helps control energy costs. Each series is project-customizable, with hurricane impact testing support available on qualifying configurations.
Product Features
Salt-spray corrosion resistance: PVDF or anodized finishes and 304 stainless hardware help the aluminum sliding door corrosion resistant design endure coastal air and humidity.
Wind-resistant structure: Tested to 4.5 kPa or Grade 9 wind load, these impact sliding doors coastal engineering keep interiors safe during typhoons and hurricanes.
Watertight performance: With 300–350 Pa water tightness and hidden drainage, the sliding door prevents rain ingress in exposed seaside locations.
Large panoramic glass: Narrow frame sightlines and double tempered IGU expand ocean views, connecting indoor spaces with seaside surroundings.
Thermal efficiency: Low U-values (2.3–2.5 W/m²·K) reduce heat transfer, supporting energy-efficient building envelopes in hot or temperate coastal climates.
Project customization: A complete seaside aluminum sliding door system with multiple series, sizes, and finishes to meet specification from villas to commercial buildings.
Customizable Styles
Glass options: Clear, Low-E, laminated, tinted, reflective, triple glazed, argon fill — tailored to project energy and safety needs.
Frame finishes: Powder coating, PVDF, anodized, wood grain — all suitable for coastal exposure and aesthetic requirements.
Size customization: Doors built to project opening dimensions, from narrow balcony sliders to extra-wide panel assemblies spanning multiple meters.
Track configurations: Low track, waterproof high track, copper bar, concealed drainage, barrier-free — match threshold and drainage design.
Special configurations: Arched tops, column-free 90° corners, integrated magnetic or electric blinds — support unique architectural ideas.
Hardware Accessories
304 stainless steel hook locks and handles: Resist salt corrosion while providing secure multi-point locking for coastal sliding doors.
Silent four-wheel or double-row large roller systems: Deliver smooth sliding action and quiet operation even with heavy glass panels.
Anti-typhoon wheel and anti-sway designs: Keep door panels on track during high winds, enhancing hurricane resistant sliding doors performance.
Optional smart controls: Electric opening with remote, fingerprint, or face recognition available on select series; confirm per model.
Stainless steel security mesh screens: 304 mesh with 11-mesh count allows ventilation and visibility without compromising safety.

Application Scenarios
Apartment: High-floor coastal apartments need slim profile sliding doors that withstand wind load while framing ocean views; our systems provide Grade 9 resistance.
Home Office: A seaside home office benefits from robust sliding doors linking interior to terrace, offering daylight and salt-spray resistance.
Hotel: Coastal hotels connect guest rooms to beachfront balconies with large sliding panes that resist salt spray and wind, maintaining panoramic views.
Office Building: Commercial buildings near the sea use corrosion-resistant aluminum sliding doors for entrances or partitioned workspaces; confirm wind load and coating durability.
Outdoor: For semi-exposed corridors or courtyards, verify weather resistance and drainage; hardware must handle high humidity and occasional salt spray.
Residential Building: Multi-residential coastal developments need durable sliding doors meeting energy codes and wind-driven rain resistance; customizable for unit sizes.
Exterior: As exterior building doors, sliding systems must balance weatherproofing and design; confirm water tightness and wind pressure for installation exposure.
Villa: Luxury seaside villas demand expansive sliding doors merging indoor living with terraces; column-free corners and premium finishes fit the vision.
