Premium Exterior Sliding Door Hardware – Engineered for Security, Weather Resistance & Seamless Operation
🔹 Extreme Load & Wind Resistance
880 lbs (400kg) Capacity: Reinforced cold-rolled steel tracks (6mm thickness) with dual-bearing rollers, tested to withstand 50 mph wind loads
Anti-Derailment System: Quadruple gravity-driven locking disks prevent door displacement during storms or forced entry attempts
🔹 All-Weather Durability
Marine-Grade Corrosion Protection: 304 stainless steel components + electrostatic powder coating (1,500-hour salt spray test rating) for coastal/high-humidity zones
Thermal-Expansion Compensation: Track expansion joints absorb ±4mm dimensional changes (-40°F to 120°F), eliminating warping or binding
🔹 Security Fortification
Multi-Point Locking: 3–5 hook latches engage simultaneously with reinforced strike plates (resists 1,200N shear force)
Anti-Lift Technology: Interlocking floor guides + vertical deadbolts block upward force intrusion
🔹 Frictionless Operation
Silent Sealed Bearings: POM nylon rollers with IP66-rated seals repel dust/moisture, reducing friction by 40% (≤20dB noise)
