Buying Guide: Key Purchase Considerations
- Material: Aluminum signs resist rust and weathering; plastic signs can be lighter and may meet standards, but might show wear sooner in harsh conditions.
- Reflectivity: Diamond-grade reflectivity improves nighttime visibility; higher mil thick materials generally last longer in sun exposure.
- Size and shape: Standard 14″ x 16″ triangles are broadly recognized and easy for drivers to notice from a distance.
- Mounting: Some signs include mounting brackets or pre-drilled holes. If not, plan to buy compatible hardware separately.
- Standards compliance: If you operate on public roads, verify ASAE S276.4 and DOT compliance to ensure legal use.
- Durability vs. cost: Aluminum options offer longer lifespans; plastic options may be cheaper upfront but can show wear faster.
- Weather conditions: For frequent rain, sun, or salt-road exposure, prioritize rust-resistant aluminum and sealed surfaces.
- Application scope: Choose a sign that suits golf carts, tractors, ATVs, or UTVs, and consider whether you need a sign that doubles as a mounting platform.
