Maintenance Tips: Wipe aluminum alloy door face quarterly with clean water or neutral cleaner; regularly brush screen netting with soft brush to remove dust; inspect seal strip elasticity and integrity annually; lubricate locks annually; check frame fixing screws for loosening after strong wind seasons.
We offer three distinct screen netting options: Stainless Steel Mesh (for maximum anti-theft protection and structural strength), Nylon Mesh (economical, lightweight, and effective insect-proofing), and Fiberglass Mesh (highly resistant to corrosion, making it ideal for coastal and humid environments).
Yes. DERCHI doors support both classic Swing opening and space-saving Push-and-Pull opening methods. Our engineering team can recommend the optimal configuration based on your building's architectural drawings and spatial needs.
The door frame is built from high-strength aluminum alloy which is naturally immune to rust. Combined with multi-channel weatherstripping and reinforced frame structures, it blocks sand and wind effectively while maintaining seal integrity in harsh coastal or windy climates.
We provide comprehensive project support including 3D model designs. This allows clients to visually preview the overall aesthetic fit of the door with the building design before factory production starts.
We provide a comprehensive 3-year warranty covering the door body structure and surface finishing, along with a 2-year warranty for screen netting, locks, and sealing systems, supported by online technical assistance.
