Frequently Asked Questions & Technical Specs
Get quick answers to common technical queries regarding our manufacturing standards, materials, and international shipping options.
What are the benefits of choosing aluminum over wood or steel?
Aluminum offers superior structural stability, resistance to corrosion, low maintenance, and design versatility compared to wood. Unlike steel, it does not rust in coastal environments, making it the perfect choice for long-lasting external entry doors.
Do your doors meet local building codes in North America and Australia?
Yes. DERCHI doors hold NFRC (USA), AS2047 (Australia), CSA (Canada), and CE (Europe) certifications. We customize the glass and structural profiles to match your regional wind load and energy efficiency requirements.
What is the lead time for custom container orders?
Generally, our standard production lead time is between 30 to 45 days after design approval and deposit receipt, depending on the complexity and volume of the custom designs.
How does the Four-Side Six-Point Lock work?
This patented mechanism locks the door frame at six different locations across all four sides when engaged. This distributes force evenly and prevents leverage points, providing world-class security against forced entry.
