Buying Guide
- Material choice: Foam boards are lightweight and budget-friendly for indoor use, while corrugated plastic (coroplast) is better for outdoor weather exposure and longer-term displays.
- Durability and weather resistance: For exterior signage, UV-resistant inks and waterproof substrates extend sign life. Double-sided options maximize visibility.
- Size and shape options: Common sizes include 24×36 for A-Frame and poster displays. Consider square vs. rectangular shapes based on venue space and mounting.
- Mounting and portability: Lightweight boards are easy to transport. Look for frames that require minimal setup and offer stable stands or inserts.
- Customization capabilities: Check if suppliers offer full-color prints, logos, and text customization with quick turnaround for events and campaigns.
- Made in USA and quality control: Domestic production can offer faster fulfillment and compliance with local regulations for events.
- Cost considerations: Foam boards provide economical signage for short-term use, while durable coroplast options may incur higher upfront costs but last longer.
