Designed for urban apartments, condominiums, loft conversions, and contemporary townhouses where the industrial-chic aesthetic is desirable. The integrated mail slot makes it especially practical for multi-unit residential buildings where centralized mailboxes are not standard. Architects and interior designers appreciate the OEM/ODM flexibility to match building design specifications while maintaining CE compliance.

Q: What are the installation requirements for this steel security door?

A: Our doors are designed for installation in standard exterior door rough openings. The door comes pre-hung in a reinforced steel frame with pre-installed hinges and weather stripping. Installation requires basic carpentry tools, a level, shims, and expanding foam sealant for the frame perimeter. We provide detailed English installation manuals, and our technical team is available for remote consultation. The adjustable 3D hinges allow fine-tuning of alignment after installation.

Q: How do you ensure consistent quality across OEM/ODM orders?

A: Every production batch undergoes comprehensive quality inspection including: raw material mill certificates (steel gauge, zinc coating weight), in-process checks at each manufacturing station, finished product dimensional inspection, coating thickness measurement (60–80 micron target), adhesion testing (cross-hatch method), and functional testing of all moving parts. Pre-shipment inspection reports with photos are provided. Our ISO 9001:2015 system and CE EN 14351-1 certification ensure documented, repeatable quality.
