Stainless steel photoluminescent fire safety directional signs are essential auxiliary escape and evacuation indicators currently mandated for installation in rail transit systems. They must be placed on platform floors, station walls, and stair exits to direct towards safety exits. According to national regulations, these signs must be made of 304 stainless steel as the base material, infused with long-afterglow photoluminescent powder.

     Our company's manufactured photoluminescent evacuation sign systems for subways absorb visible light for 5-10 minutes and can continuously emit light in dark environments for over 12 hours. The luminescent effect has no half-life and can be cyclically used for more than 30 years. As long as there is no human damage, replacement is unnecessary, offering a once-and-for-all solution. In emergencies such as power outages or fires in underground rail transit, these signs effectively guide crowd evacuation. 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 vertically brushed metal surface for aesthetic appeal;
2. Surface pattern 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 high-quality glow powder, non-toxic, harmless, and radiation-free, with a safety coefficient higher than electrically powered evacuation indicators;
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, Suzhou Metro, Changsha Metro, Xi'an Metro, Chengdu Metro, Nanchang Metro, and Shenyang Metro.

 

III. Dimensions and Patterns:
 210*230*5mm, using stainless steel base material, with the photoluminescent part made from our high-brightness quality glow powder, offering bright luminescence with no half-life. 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 embedded.

 

V. Disadvantages and Advantages of Metal Processing Techniques

① Metal Casting Process

Disadvantages:
1: Long production cycle (mold opening takes 15-21 working days);
2: Slightly heavier than etched metal parts;
Advantages:
1: High出貨率 (output rate), once the mold is completed, daily output can reach at least 200 pieces;
2: Low unit cost for large quantity bases;
3: Deep groove depth;
4: Aesthetically pleasing surface with清晰可見(jiàn) (clearly visible) metal streaks;
② Metal Etching Process
Disadvantages:
1: High報(bào)廢率 (scrap rate);
2: Shallow groove depth and粗糙 (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 bases;
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: Great advantage for urgent orders

 

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