Our 10mm Extra Thick Corrugated Plastic Yard Signs are heavy-duty coroplast signs made for full-color indoor and outdoor signage where a thicker, more rigid material is preferred. Compared to standard 4mm corrugated plastic, 10mm coroplast offers added strength and durability for property signs, parking signs, construction signs, real estate signs, political campaign signs, event signage, directional signs, business promotions, job site signs, school signs, church signs, and outdoor advertising in areas exposed to tougher conditions.
Corrugated plastic has a subtle linear flute pattern that may be faintly visible on the finished sign. H-stands require vertical flutes and work best when the sign width is greater than the height.

Custom 10mm extra thick corrugated plastic yard signs are a heavy-duty large format printing option for property signs, parking signs, construction signs, real estate signs, political campaign signs, directional signs, event signs, business promotions, school signs, church signs, job site signs, and durable outdoor advertising.
SoCal Business Cards provides professional large format printing for businesses, contractors, real estate agents, property managers, schools, churches, event planners, political campaigns, and organizations across Southern California including Costa Mesa, Irvine, Huntington Beach, Newport Beach, Anaheim, Los Angeles, and San Diego. Our extra thick yard signs are printed in full color on 10mm corrugated coroplast plastic for indoor and outdoor display.
These custom 10mm coroplast signs are available with one-sided or two-sided printing, vertical or horizontal flute direction, optional grommets, optional heavy duty H-stand hardware, exact cut size requests, and graphic design services. They are commonly used for heavy-duty yard signs, job site signs, parking signs, property signs, wayfinding signs, outdoor promotional displays, and longer-term temporary signage.
10mm corrugated plastic signs are a stronger, more rigid option compared to standard 4mm yard signs. They are a good choice for customers who want a heavier-duty coroplast sign for outdoor visibility, property use, job sites, event signage, directional signage, and promotional displays in areas exposed to tougher conditions.
Standard 4mm yard signs are best for common lawn signs, campaign signs, real estate signs, and temporary promotional displays. Extra thick 10mm corrugated plastic signs are better for heavier-duty displays, parking signs, construction signs, property signs, and longer-term signage where a thicker and more rigid material is preferred.
For signs ordered with H-stands, vertical flute direction is required so the stand can slide into the corrugated channels. The corrugated flute structure may create a subtle linear effect on the sign surface, which is normal for coroplast signs.
Pair your extra thick yard signs with large format printing, standard corrugated plastic yard signs, custom vinyl banners, and custom vehicle magnets for a consistent branded presentation.
