Our company manufactures photoluminescent evacuation indicator systems for subways, which absorb visible light for 5-10 minutes and can continuously emit light in darkness for over 12 hours. The luminescent effect has no half-life and can be sustainably reused for more than 30 years. Once installed, it requires no replacement unless deliberately damaged, offering a permanent solution. In emergencies such as power outages or fires in underground rail transit, these indicators effectively guide crowds to evacuate 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 graphic grooves can reach a depth of 1.2mm, with photoluminescent brightness higher than conventional market glow-in-the-dark signs, and不易脫落 (not easily脫落);
3. The photoluminescent part uses our company's X-quality luminous powder, which is non-toxic, harmless, and radiation-free, with a safety coefficient higher 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 subways in cities such as Shanghai Metro, Hangzhou Metro, Shenzhen Metro, Wuhan Metro, Suzhou Metro, Changsha Metro, Xi'an Metro, Chengdu Metro, Nanchang Metro, and Shenyang Metro.

III. Dimensions and Patterns:
224*167*3mm, using stainless steel plate as the base material, with the photoluminescent part made from our company's X-quality high-brightness luminous powder. Features a small triangular design,美觀簡潔 (aesthetic and簡潔). Already used in Shenzhen Metro, Wuhan Metro, Xiamen Metro, etc., custom patterns, colors, and dimensions are supported.

IV. Installation Method
Simply pre-groove according to the sample size, apply AB adhesive at the bottom during installation, and wait for it to solidify; alternatively, through grooving, the product can be directly鑲嵌其中 (embedded into it).

V. Disadvantages and X-points of Metal Processing Techniques

① Metal Casting Process
Disadvantages:
1: Long production cycle (mold opening time cycle is 15-21 working days);
2: Slightly heavier than etched metal parts;
X-points:
1: High出貨率 (output rate), once the mold is completed, output can reach at least 200 pieces per day;
2: Low unit cost when the quantity base is large;
3: Deep groove depth;
4: Surface is美觀 (aesthetic) with clearly visible metal streaks;
② Metal Etching Process
Disadvantages:
1: High報廢率 (scrap rate);
2: Shallow groove depth and rough surface patterns;
3: Impacts the health of processing workers;
4: Causes environmental pollution;
X-points:
1: Lower cost compared to cast parts when the quantity base is small;
2: Shorter production cycle compared to cast parts;
③ Metal Engraving Process
Disadvantages:
1: Slow engraving speed, relatively time-consuming;
2: Engraved blanks require manual cleaning;
X-points:
1: Convenient and quick sample production;
2: Offers great X-勢 (advantage) for urgent orders

VI. Other Notes
For custom sizes and patterns, there is generally a minimum order quantity. The specific成品發(fā)貨時間 (finished product delivery time) depends on the product manufacturing process and quantity. Welcome to call for inquiries.
