Subway station hall luminous stainless steel ground boarding and alighting self-luminous glow-in-the-dark signage

The photoluminescent evacuation indicator system manufactured by our company absorbs visible light for 5-10 minutes and can continuously emit light for over 12 hours in darkness. The luminescent effect has no half-life and can be recycled for more than 30 years. It requires no replacement unless manually damaged, offering a once-and-for-all solution. In emergency situations such as power outages or fires in underground rail transit, it effectively guides crowd evacuation and escape. With the rapid development of underground rail transit in recent years, the use of stainless steel products has become more widespread.

I. Product Features
1. Made of SUS304 stainless steel, durable and long-lasting, with a beautiful vertical brushed finish on the metal surface;
2. Surface pattern groove depth up to 1.2mm, with higher photoluminescent brightness than conventional market glow-in-the-dark signs, and less prone to peeling;
3. The photoluminescent part uses high-quality luminous powder, non-toxic, harmless, and radiation-free, with a higher safety factor than electrically powered evacuation indicator floor markers;
4. Easy and quick installation, no need for pre-wiring;
5. No power supply required, energy-saving, environmentally friendly, and safe.

II. Applicable Scope:
    This product is not only suitable for subway projects but also for shopping malls, factories, supermarkets, etc. Currently, our products have been applied in urban subways such as Shanghai Metro, Hangzhou Metro, Shenzhen Metro, Wuhan Metro,

V. Disadvantages and Advantages of Metal Processing Techniques

① Metal Casting Process

Disadvantages:
1: Long production cycle (mold development takes 15-21 working days);
2: Slightly heavier than etched metal parts;
Advantages:
1: High output rate, with daily production of at least 200 pieces once the mold is completed;
2: Low unit cost for large quantity orders;
3: Deep groove depth;
4: Aesthetically pleasing surface with clearly visible metal grain;
② Metal Etching Process
Disadvantages:
1: High scrap rate;
2: Shallow groove depth and rough surface patterns;
3: Negative impact on the health of processing workers;
4: Causes environmental pollution;
Advantages:
1: Lower cost compared to cast parts for small quantity orders;
2: Shorter production cycle compared to casting;
③ Metal Engraving Process
Disadvantages:
1: Slow engraving speed, relatively time-consuming;
2: Engraved blanks require manual cleaning;
Advantages:
1: Convenient and quick sample production;
2: Significant advantage for urgent orders

VI. Other Notes
