Corrugated Plastic vs Aluminum for 500 Temporary Outdoor Signs

Choosing the right material for 500 temporary outdoor signs comes down to a few simple factors: cost, durability, installation ease, and what you actually need the signs to do. For most customers ordering a large batch of custom yard signs for short-term display, corrugated plastic is usually the recommended choice over aluminum. This guide will walk you through the reasons why, and give you clear, actionable tips for sizing, ordering, and placing your signs for maximum impact.

What Is Corrugated Plastic? What Is Aluminum?

Corrugated plastic is a lightweight, weather-resistant plastic sheet commonly used for yard signs, campaign signs, and event signage. It’s also called Coroplast. The material is made of two flat plastic layers connected by flutes, making it rigid yet easy to handle. Most yard signs use 4mm thickness, which balances stiffness and low weight.

Aluminum signs are made from solid, rigid sheets of metal. They are weatherproof, long-lasting, and very sturdy, suitable for situations where the sign will stay up for years and not just days or weeks. Aluminum is heavier and costs more to produce and ship.

Corrugated Plastic vs Aluminum: Which Is Better for 500 Temporary Outdoor Signs?

For large orders of temporary outdoor signage—such as those needed for campaigns, school fundraisers, business promotions, or events—corrugated plastic is almost always the smarter choice. Here’s why:

• Lower Cost: Corrugated plastic signs cost much less per sign, which adds up quickly with bulk orders like 500 pieces.
• Lightweight: They’re easier (and cheaper) to ship in large numbers.
• Weather-Resistant: Corrugated plastic stands up well to rain, sun, and wind for weeks or months.
• Fast to Install: Most come with H-stakes for easy placement in lawns or along roads.
• Flexible Placement: They are safe for putting at intersections, sidewalks, and yards.

Aluminum signs are better when you need truly permanent outdoor signage or when mounting signs directly to a wall or fence for years at a time. For most customer needs—especially anything that is short-term or for a seasonal campaign—aluminum costs more than necessary.

Recommended Specs for Temporary Outdoor Signs

• Material: 4mm corrugated plastic (weatherproof, lightweight, cost-effective)
• Size: Choose based on visibility needs. Common sizes are 12x18 inches for small text or tight spaces, 18x24 inches for high visibility, or 24x36 inches for extra impact. Many customers find 18x24 inches is ideal for busy streets or open areas.
• Printing: Choose bold, high-contrast colors with large fonts. Simple messages work best. For visibility tips, see our guide on yard sign font size and signage readability.
• Installation: H-stakes slip into the flutes and push easily into the ground. Use gloves and check for hard soil or hidden rocks when installing many signs at once.

Bulk Ordering Advice: Why 500 Signs?

If you need 500 signs, you’re likely seeking high visibility for a short period—such as a political campaign, weekend event, school fundraiser, or property promotion. Corrugated plastic is designed for these needs. It’s cost-efficient to print in bulk, and easy to distribute among volunteers or staff. Signs weigh much less than aluminum, so they’re easier to move and install quickly in multiple locations.

When Aluminum Makes Sense

There are specific cases when aluminum is the better choice for outdoor signage:

• You need each sign to last for multiple years in the same place.
• You are mounting the sign to a wall, fence, or post, not a yard stake.
• The location is subject to frequent vandalism, high wind, or severe weather, and you want a rigid, metallic finish.

For parking lot signs, regulatory signs, or business signage with a permanent address, aluminum works well. For temporary messaging—like event or political yard signs—it’s usually not cost-effective.

How to Place 500 Yard Signs for Results

• Keep text short: Aim for five words or less. Drivers only have seconds to read your sign.
• Face signs toward oncoming traffic. Place at eye level or slightly below waist height for best visibility.
• Space signs evenly. Avoid placing in cluttered areas or too close to other advertisements.
• Check local rules. Some cities limit where signs can be placed. Make a quick plan before deployment so volunteers know what’s allowed.

Using consistent sign size, design, and placement will help your campaign look professional. For reference, our directional signs placement guide provides more details on this topic.

Summary: Why Corrugated Plastic Is the Practical Choice

If you need 500 custom signs for a short-term outdoor promotion, school event, or campaign, choose corrugated plastic for cost savings, convenience, and ease of use. Keep your campaign visually consistent and make installation easy for everyone. For permanent facility signs, aluminum is a strong upgrade, but for the majority of temporary signage, it’s more than you usually need.
