Gold Slot Black Steel Security Door Commercial Metal Doors Moisture-Proof Smart Lock Number Plate Home

Complete your home with the Gold Slot Black Steel Security Door by YSM — where premium protection meets refined design. This entry door features elegant gold-accented hardware — mail slot, number plate, and lock escutcheon — set against a sophisticated moisture-proof matte black finish. The galvanized steel core provides exceptional anti-rust and anti-corrosion performance, with a powder-coated surface that repels water, resists scratching, and stays beautiful with minimal maintenance. Operating across -20°C to 45°C, this door is engineered for long-term reliability in any climate. Full OEM/ODM customization is our specialty — non-standard sizes, custom colors, and bespoke hardware configurations are all welcome. ISO 9001:2015, CE EN 14351-1, RoHS compliant.

• Premium gold-accented hardware package included — mail slot, house number plate, and lock escutcheon in polished brass or satin gold finish, corrosion-protected with clear PVD (Physical Vapor Deposition) coating for long-lasting brilliance
• Moisture-proof matte black surface with hydrophobic properties — water beads and rolls off the surface, reducing water spotting and mineral deposits; tested to maintain appearance after 2,000+ hours of accelerated UV/condensation cycling
• Support for fully customized non-standard sizes — whether you need a 2100mm tall opening or an extra-wide 1200mm single leaf, our flexible production line can accommodate within specified engineering limits
• CE EN 14351-1 certified with comprehensive thermal break option — for projects in cold climates, we offer a factory-installed thermal break profile reducing frame U-value by up to 40% for energy code compliance
• OEM/ODM with ISO 9001:2015 quality and RoHS compliance — we work directly with architects, developers, and importers to create door specifications from concept to container; full documentation support for customs and compliance

Designed for residential front entries, modern housing developments, apartment buildings, and single-family homes across diverse climate zones. The moisture-proof matte finish with gold accent hardware makes it a standout choice for upscale neighborhoods and luxury apartment lobbies where visual impact matters. Importers and distributors value the OEM/ODM flexibility, ISO 9001:2015 consistency, and RoHS compliance for stocking this door as a premium product line for discerning customers.

Q: How do the gold accents hold up over time in outdoor conditions?

A: All gold-accented hardware (mail slot, number plate, lock escutcheon) is finished with a PVD (Physical Vapor Deposition) clear coating over the metallic finish. PVD is significantly more durable than traditional electroplating or lacquer — it resists tarnishing, scratching, and UV degradation. Combined with regular cleaning (mild soap and water), these accents will maintain their appearance for many years. For extreme coastal environments, we recommend an optional 316 stainless steel with PVD gold finish for maximum corrosion resistance.

Q: What is your process for non-standard size orders?

A: Our OEM/ODM process for non-standard sizes works as follows: (1) You provide your required dimensions (width x height). (2) Our engineering team reviews for structural feasibility and provides a confirmation or suggests adjustments. (3) We produce a technical drawing for your approval. (4) Upon approval, we proceed to production with the same ISO 9001:2015 quality controls as standard sizes. (5) Pre-shipment inspection includes dimensional verification. Typical lead time for custom sizes is 25–35 days.
