The station hall evacuation indicator is installed on the ground passage of the subway station hall and must be installed at stair exits without interruption. The thickness of the stainless steel station hall evacuation indicator arrow is generally 2mm, while some cities use a thickness of 3mm.

However, a circular photoluminescent glass landmark is currently widely used in many cities across the country, with an outer steel ring diameter of 150mm and a base diameter of 142mm.
I. Product Performance:
1. After absorbing any visible light for 5-10 minutes, it continues to glow in the dark for over 12 hours and can be reused infinitely;
2. It uses our company's independently produced high-brightness luminous powder, which is safe, environmentally friendly, non-toxic, harmless, non-radioactive, and low-cost;
3. It adopts double-layer tempered glass (ordinary ones only have the upper layer as tempered glass, while the lower layer is ordinary glass). The photoluminescent interlayer uses high-brightness full-luminous aluminum plates, vacuum-sealed and laminated in a furnace, with waterproof and moisture-proof levels up to IP68. The edges are framed with 304 stainless steel, making it aesthetically pleasing.
4. The photoluminescent fire safety evacuation signs must meet the requirements of GA480.3-2004 in terms of weather resistance, color adhesion, corrosion resistance, impact resistance, water resistance, and radioactivity.

II. Specifications:
The conventional size of the circular glass station hall sign is φ150mm. The arrow pattern can be customized according to requirements, and text can be added.

III. Applicable Scope:
Subways, factories, light rails, shopping malls, etc. Currently, subways in Shenyang, Changchun, Beijing, Tianjin, Xi’an, Changsha, Guiyang, Ningbo, etc., use the above φ150mm ground evacuation indicators without text.
