Buying Guide — Key Considerations For Exterior Building Signs
- Material and rust resistance: Aluminum signs with .040 thickness are common for outdoor use, offering corrosion resistance and durability without the weight or rigidity concerns of steel.
- Weatherproofing and UV stability: Look for laminated graphics or UV-resistant inks to prevent fading from sun exposure and to withstand rain, snow, and hail.
- Visibility and readability: Consider sign size, reflective coatings, and contrast to ensure legibility from distance and in low light conditions.
- Mounting options: Pre-drilled holes and compatibility with vertical or horizontal installation support quick, tool-friendly mounting on walls, posts, or doors.
- Customization capabilities: If branding, safety messaging, or directional cues are critical, prioritize suppliers offering easy customization with color and text control.
- Durability vs. cost: Heavier, thicker aluminum with protective laminates generally lasts longer but may come at higher upfront cost. Balance budget with expected outdoor exposure.
- Local regulations: Some municipalities have sign size, placement, or lighting guidelines—verify compliance before purchasing.
- Warranty and service: Check for guarantees on outdoor performance and availability of replacement parts or graphics.
