Advantages of aluminum blanks for road traffic signs:
No Rust: Aluminum naturally resists corrosion and rust, even in harsh weather or coastal/salty environments.
Longevity: Ensures a long service life (5+ years) with minimal maintenance, reducing long-term replacement costs.
Weatherproof: Withstands extreme heat, UV exposure, rain, and snow without warping or cracking.
Easy Handling: High strength-to-weight ratio makes signs lighter than steel, ensuring easier, faster, and safer installation.
Lower Logistics Costs: Reduced weight lowers shipping and transportation expenses per unit.
Optimal Adhesion: Surface is chemically treated for superior bonding with reflective sheeting (essential for MUTCD compliance).
Highly Recyclable: Aluminum is 100% recyclable, offering high scrap value and supporting eco-friendly infrastructure goals.
Fabrication Ease: Easily cut, punched, and shaped to meet all standardized and custom sign specifications.
Our aluminum blanks come in various sizes and gauges, they have pre-drilled holes for mounting hardware.
All blanks can provide with radius corners and surface color coating by using high-quality 5052-H38 or 3003 H24 aluminum. Mill certifications are available upon request.

Aluminum round blanks are the primary raw material for manufacturing regulatory, warning, and guide signs. Their popularity stems from aluminum's excellent properties:
High Strength-to-Weight Ratio: Easy to handle and install.
Corrosion Resistance: Withstands harsh outdoor weather conditions.
Durability: Long service life, reducing replacement frequency and cost.
Formability: Can be cut, punched, and formed easily.
Excellent Surface for Coating: Provides a perfect base for reflective sheeting and paints.
We provide strong and exporting standard packages to ensure that the aluminum round blanks arrive at their destination in pristine condition, ready to be installed or fabricated into vital traffic safety signs.
