Ribbed Grid Black Steel Front Door Commercial Metal Door Frame Smart Lock Matte Black Gray Double

The Ribbed Grid Black Steel Front Door by YSM is a premium commercial-grade security door designed for modern homes and businesses that demand both style and substance. The distinctive ribbed and grid-patterned surface is not just for aesthetics — it is stamped from a single sheet of 1.5mm+ galvanized steel, increasing structural rigidity by up to 40% compared to flat panel doors. The dual-layer anti-corrosion coating (zinc-rich primer + UV-stabilized matte powder coat) has been tested to outperform standard finishes by 3x in accelerated weathering tests. Available in single and double door configurations with full OEM/ODM customization. ISO 9001:2015, CE EN 14351-1, and RoHS certified.

• Unique ribbed and grid surface patterns stamped from single-sheet galvanized steel — these structural embossments increase panel rigidity by up to 40% while adding distinctive architectural character that sets your entrance apart
• Available in single and double door configurations — double doors feature an active/passive leaf design with flush bolts, astragal, and coordinated hardware for seamless operation and complete weather sealing at the meeting stile
• Dual-coat anti-corrosion system exceeding 1,500 hours salt spray resistance — zinc-rich epoxy primer + UV-stabilized matte powder topcoat ensures decades of rust-free performance in marine, industrial, and high-pollution environments
• CE EN 14351-1 certified with enhanced wind load resistance — the embossed panel design inherently improves structural performance under wind pressure, making these doors suitable for high-rise and exposed locations
• ISO 9001:2015 factory with RoHS compliance — our automated powder coating line with 12-stage pretreatment tunnel ensures consistent finish quality across large production runs; custom color matching available via spectrophotometer

Perfect for residential front doors in modern homes, apartments, villas, and condominium complexes. The elegant gold accents make it especially popular in markets that value refined aesthetic details — Middle East, Southern Europe, and upscale North American neighborhoods. Its non-standard size capability through OEM/ODM manufacturing makes it suitable for custom-built homes and renovation projects.

Q: What is the difference between your single and double door configurations in terms of installation and performance?

A: Our double door configurations feature an active leaf (primary operating door) and a passive leaf (secured with flush bolts top and bottom). Both leaves share the same heavy-duty steel construction. The meeting stile is fitted with an astragal and EPDM weather seal for complete air and water tightness. Installation of double doors requires a wider rough opening and additional framing preparation, which our technical team can guide you through. Both configurations meet CE EN 14351-1 performance standards.

Q: Can the ribbed/grid pattern be customized to a specific design?

A: The stamped embossed patterns require dedicated tooling, which is economical for OEM/ODM orders of 200+ units per design. For smaller quantities, we can offer alternative decorative options including applied mouldings, CNC-routed patterns, or laser-cut overlays that achieve a similar dimensional aesthetic without the tooling investment. Our engineering team can advise on the most cost-effective approach based on your design requirements and order volume.
