Product Details
Sliding patio door manufacturers like DERCHI invest heavily in thermal performance and weather resistance. The 143 and 135F Series use 6063-T5 thermally broken aluminum with double tempered glass and argon fill, achieving U-values of 2.5 W/(m²·K). Patented anti-typhoon upper wheels and concealed vertical drains provide up to 4.5 kPa wind resistance and 350 Pa water tightness, protecting coastal and high-rise buildings.
Unlike generic doors, our manufacturing follows 168 standardized steps with a 38-point physical test on every unit. This consistency supports bulk orders while allowing oversized panels (up to 16 feet), automation integration, and multi-track setups. Buyers receive a documented quality record, simplifying procurement for large-scale developments.
Product Features
Insulated Frame Construction: Polyamide-reinforced 6063-T5 profiles separate interior and exterior aluminum, cutting heat transfer to help meet energy codes.
Typhoon-Ready Wind Resistance: Patented anti-oscillation rollers and reinforced interlocks handle 4.5 kPa loads, suitable for hurricane-prone regions.
Multi-Point Locking Security: Four-sided six-point lock systems engage multiple hook bolts for forced-entry resistance on ground-floor applications.
Superior Water Management: Hidden vertical floor drains with a patented design achieve 350 Pa water tightness, preventing leakage during heavy rain.
Acoustic Comfort: Argon-filled double glazing with PVDF warm-edge spacers reduces external noise by up to 32 dB, well-suited to urban noise conditions.
Large-Opening Capability: Panels can span 5 to 16 feet wide and support up to 1000 kg, with top-hung or bottom-rolling configurations.
Customizable Styles
Glass Options: Double or triple glazing with Low-E coatings, tinted, laminated, or argon-filled units to meet energy and security needs.
Frame Finishes: Powder coating, PVDF fluorocarbon, anodized, or wood-grain transfer for architectural consistency.
Size & Configurations: Fixed panels, single or double sliders, multi-track stacking; openings up to 16 ft wide and 12 ft tall.
Track Style: Bottom-rolling for straightforward installation or top-hung for a seamless floor transition.
Color Matching: Custom RAL or Pantone colors available upon request, ensuring facade integration.
Hardware Accessories
Silent Rollers: Four-wheel carriages with stainless steel bearings deliver smooth operation under heavy panel loads.
Multi-Point Hook Locks: Die-cast aluminum handles with optional four-sided six-point locking for added security.
Anti-Typhoon Upper Wheels: Patented design prevents panel disengagement during extreme wind events.
Concealed Vertical Drains: Hidden within the bottom rail, this patented system channels water without disrupting clean lines.
Compatible Hardware Brands: Integration with WEHAG, HOPO, PAG, VBH, and others gives buyers procurement flexibility.
