The finish material of a revolving door significantly impacts both aesthetic appearance and long-term durability in different environmental conditions. This article compares stainless steel and titanium gold finishes to help buyers make appropriate selections for specific applications.
1. Stainless Steel Finishes
Stainless steel revolving doors typically use 304 grade stainless steel for interior applications or 316 grade for coastal installations exposed to salt air. Brushed finish provides a contemporary appearance that hides minor scratches and fingerprints well. Mirror polish finish creates a high-end appearance but requires more maintenance to preserve the finish. PVD coating options provide colored stainless steel in black, bronze, or champagne gold tones with improved scratch resistance compared to standard finishes.
2. Titanium Gold PVD Finishes
Physical vapor deposition coating creates titanium nitride and titanium carbonitride finishes in various gold tones ranging from bright 24K gold to subtle champagne gold. PVD coating provides excellent scratch resistance and color stability under UV exposure. The coating thickness of 0.5-2 microns maintains finish integrity for 15-20 years in normal environments. This finish is popular in luxury hotel applications where warm gold tones complement interior design schemes.
3. Coastal Environment Performance
For coastal installations within 5 kilometers of saltwater environments, stainless steel 316 grade provides necessary corrosion resistance. Standard 304 stainless steel will develop surface rust and pitting within 2-3 years in coastal conditions despite its stainless designation. Titanium gold PVD coatings on 316 stainless steel substrates provide both corrosion resistance and aesthetic variety for coastal luxury applications.
4. Maintenance Requirements
Stainless steel finishes require regular cleaning with appropriate stainless steel cleaners to maintain appearance. Avoid abrasive cleaners that damage protective oxide layers. PVD coatings clean easily with mild detergent and soft cloth. The hardened surface resists scratching from normal use and cleaning. Neither finish requires waxing or periodic refinishing under normal conditions.
5. Cost Comparison
Stainless steel finishes typically add 15-25% to base door pricing depending on grade and surface treatment. PVD titanium gold finishes add 30-50% to base pricing for the coating process and specialized handling required. Evaluate total project budget including any premium charged for matching adjacent hardware finishes in the surrounding lobby area.
