Material and Durability of Exit Signs with Arrows
Exit signs with directional arrows are critical safety devices designed to guide occupants to emergency exits during power outages, fires, or other hazardous situations. Their effectiveness relies heavily on consistent durability, high visibility, and the quality of materials used in construction. These factors ensure reliable performance under extreme conditions, including exposure to moisture, impact, and prolonged UV radiation. The choice of materials varies significantly depending on the environment—indoor, outdoor, industrial, or commercial—and the required longevity of the sign.
Key Materials Used in Exit Signs with Arrows
Plastics: Acrylic & Polycarbonate
Plastic-based exit signs are among the most widely used due to their excellent balance of strength, lightweight design, and resistance to environmental stressors. Acrylic (PMMA) and polycarbonate are the two primary materials employed.
Acrylic offers exceptional clarity and surface gloss, making it ideal for signs requiring high visual appeal and legibility. It is commonly polished to enhance reflectivity and brightness, especially in illuminated models. While slightly more brittle than polycarbonate, acrylic resists yellowing and maintains color integrity over time.
Polycarbonate, on the other hand, provides superior impact resistance—up to 200 times stronger than glass—making it suitable for high-traffic or vandal-prone areas such as schools, hospitals, and public buildings. Both materials perform well indoors and outdoors, though polycarbonate is often preferred in harsher environments due to its toughness.
Metal: Steel & Aluminum
Metal exit signs are engineered for maximum durability and are commonly used in industrial, commercial, and outdoor settings where mechanical strength and longevity are paramount.
Steel signs offer exceptional resistance to physical damage and are ideal for heavy-duty applications such as factories, warehouses, and construction sites. They are often coated with protective finishes to prevent rust and corrosion, though regular maintenance may be required in humid or coastal environments.
Aluminum signs are lighter, easier to install, and naturally resistant to rust and corrosion, making them a top choice for outdoor installations. Their lightweight nature does not compromise strength, and they maintain structural integrity under extreme weather conditions. Aluminum is also non-magnetic and electrically non-conductive, adding to its safety profile in sensitive environments.
Edge-Lit Technology & Optical Materials
Modern illuminated exit signs increasingly use edge-lit technology, which relies on precise optical materials to distribute light evenly across the sign face. These signs typically use clear or frosted glass-reinforced acrylic panels that act as light guides.
The frame and light-transmitting components are constructed from high-grade acrylic due to its excellent light transmission properties, durability, and ability to diffuse LED lighting uniformly. Frosted finishes help eliminate hotspots and provide consistent illumination, enhancing readability from multiple angles.
This technology not only improves visibility in low-light or smoke-filled environments but also reduces energy consumption by maximizing the efficiency of internal LEDs. Edge-lit signs are commonly found in office buildings, hotels, and healthcare facilities where aesthetics and reliability are both important.
Protective Coatings & Environmental Resistance
To extend service life and maintain performance, many exit signs—especially illuminated ones—are treated with advanced protective coatings. Powder coating and polymer-based finishes are applied to metal and plastic surfaces to enhance resistance to environmental degradation.
These coatings protect against UV radiation, preventing color fading and material brittleness caused by prolonged sun exposure. They also guard against chemical exposure, electrical arcing, moisture ingress, and physical abrasion—critical in industrial or outdoor installations.
UV-stable inks and laminates are often used in conjunction with coatings to preserve the arrow symbol and text clarity. This ensures that the directional information remains legible for the entire lifespan of the sign, typically 10+ years, even under intense sunlight or harsh weather conditions.
