Buying Guide: Key Considerations For Selecting Closed-To-The-Public Signs
- Material durability: Choose aluminum for weather resistance and longevity; plastic is a budget-friendly option for indoor use, while tin signs offer rustic appeal but may wear differently over time.
- Size and visibility: Larger signs deliver greater visibility from a distance; smaller signs suit narrow hallways or door frames. Consider font size and color contrast for legibility.
- Mounting options: Look for signs with pre-drilled holes and rounded corners for easy, safe installation. Ensure the mounting method matches your venue (screws, bolts, or adhesive).
- Regulatory alignment: OSHA or ANSI-compliant messaging helps meet safety standards and reduces liability. Verify wording and wording updates for your jurisdiction.
- Outdoor vs. indoor use: Verify signs are rated for the environment where you’ll place them. UV resistance, rust-free coatings, and weatherproof finishes extend life outdoors.
- Security and messaging: Clear phrasing such as “Not Open To General Public” or “Keep Door Closed” reduces ambiguity and improves compliance among staff and visitors.
- Aesthetics and branding: Choose signs with colors and typography that match your facility’s branding while remaining legible and authoritative.
- Cost vs. value: A small premium for premium aluminum with protective coatings often yields longer service, reducing replacement frequency and maintenance costs.
