Authorities in our business will tell in no uncertain terms that Lorem Ipsum is that huge, huge no no to forswear forever. Not so fast, I'd say, there are some redeeming factors in favor of greeking text, as its use is merely the symptom of a worse problem to take into consideration.

Product care

Anyway, you still use Lorem Ipsum and rightly so, as it will always have a place in the web workers toolbox, as things happen, not always the way you like it, not always in the preferred order.

Product Description

Mcoro Premium Corrugated Plastic Sign Blanks – The Ultimate Canvas for Your Message

Whether you are a professional printer, a real estate agent, or a business owner planning an outdoor campaign, the quality of your signage substrate matters. Mcoro Corrugated Plastic Sign Blanks are engineered in our own advanced extrusion facilities to deliver superior rigidity, vibrant printability, and long-lasting outdoor performance.

Cut to the industry-standard 24″ x 18″ dimension, our 4mm thick boards are designed with precision vertical flutes. This structural design ensures that standard 9-gauge (3.7mm) wire H-stakes slide in effortlessly and stay securely in place without damaging the board.

The ultra-smooth, specially treated surface is fully receptive to digital printing, screen printing, and vinyl graphics, ensuring your colors pop and your message remains crisp. Weatherproof, UV-resistant, and highly durable, Mcoro sign blanks will not easily warp or crack under harsh sun or heavy rain. Securely packed in heavy-duty factory boxes of 100 units, they are ready to fuel your next big campaign.

Frequently Asked Questions (FAQ)

Q1: What are these sign blanks made of?

A: They are manufactured from high-quality, 100% recyclable polypropylene (PP), making them lightweight, waterproof, and extremely durable.

Q2: What is the thickness of the boards?

A: Our standard corrugated plastic sign blanks feature a sturdy 4mm thickness, which is the industry standard for optimal balance between weight and rigidity.

Q3: Which direction do the internal flutes run?

A: The flutes are vertical (running along the 18″ height of the 24″x18″ board). This is specifically designed so you can easily insert standard wire H-stakes from the bottom.

Q4: Will they fit Mcoro 9-Gauge H-Stakes?

A: Yes, perfectly! The 4mm vertical flutes are engineered to smoothly accommodate all Mcoro 3.7mm (9-Gauge) standard and heavy-duty wire stakes without tearing the plastic.

Q5: Can I print on both sides of the board?

A: Absolutely. Both sides of the Mcoro sign blank feature a smooth, treated surface that is excellent for double-sided digital or screen printing.

Q6: Are these signs suitable for long-term outdoor use?

A: Yes. The material is waterproof and UV-resistant, making it highly capable of withstanding rain, wind, and sun exposure for extended outdoor campaigns.

Q7: Do the H-stakes come included with the boards?

A: No, this product includes the blank corrugated plastic boards only. Mcoro premium 9-Gauge H-stakes and EZ-Step stakes are sold separately.

Q8: How are these boards packaged?

A: To ensure they arrive in perfect condition, they are packed flat in heavy-duty Mcoro corrugated cardboard boxes, with exactly 100 blanks per box.

Q9: Can I cut or trim these boards myself?

A: Yes. While they come pre-cut to 24″ x 18″, the 4mm corrugated plastic can be easily cut, scored, or trimmed with a standard utility knife if you need a custom shape.

Q10: Are the boards eco-friendly?

A: Yes, they are made from Polypropylene (Resin Code 5), which is fully recyclable at most local plastic recycling facilities after your campaign is over.
