Circle Aluminum Blank

  • Circular aluminum traffic sign blanks are round, unfinished aluminum sheets that create various traffic and transportation signs. They come in standard sizes 12, 18, 24, 30, 36, and 48 inches in diameter to accommodate different signage needs.
  • The blanks are made from aluminum alloys such as 1 series, 3 series, or 5 series for their lightweight, corrosion-resistant, and durable properties. They have a smooth, flat surface that allows easy customization through digital printing, vinyl application, engraving, and more.
  • Typical thicknesses for the blanks range from 0.080 to 0.125 inches, with thicker blanks providing more rigidity for larger sign sizes. The blanks are not pre-drilled, so holes can be added later for mounting purposes.

Traffic Signs Circle Aluminum Blank – Frequently Asked Questions

Q1: What are the standard sizes for circle aluminum traffic sign blanks?

A1: Common sizes are 12, 18, 24, 30, 36, and 48 inches in diameter. 12, 18, and 24 inches are the most popular.

Q2: What thickness should I choose?

A2: 0.080, 0.100, and 0.125 inches are standard. Choose 0.125 inch for maximum stiffness on larger 36+ inch blanks. Go with 0.080 inch to save costs on more minor 12-18 inch signs.

Q3: Are the blanks pre-drilled with holes?

A3: No, blanks do not come pre-drilled. Mounting holes can be pre-drilled or punched during manufacturing. They can also be drilled on-site for custom placement. Countersunk spots are typical to allow flush mounting.

Q4: What are typical applications for circle sign blanks?

A4: Stop signs, yield signs, regulatory/warning signs, street signs, work zone signs, plaques, and custom traffic signs.

Q5: What manufacturing methods are used to fabricate aluminum traffic signs?

A5: Common methods include CNC machining, laser or waterjet cutting, router cutting, metal stamping, and metal spinning. The signs are then finished with powder coating, screen printing, or reflective vinyl.

Q6: What type of reflective coating do traffic signs have?

A6: Engineer-grade reflective sheeting or high-intensity prismatic sheeting is used to meet DOT reflectivity standards. Common sheeting types are Types I, II, III, VIII, IX, and X.

Q7: What shapes other than circular can aluminum sign blanks be?

A7: Common blank shapes include octagons, squares, rectangles, triangles, pentagons, diamonds, ovals, and shields/banners.

Q8: How long do aluminum traffic signs last?

A8: Properly fabricated and maintained aluminum signs can have a service life of 15-20 years. Sign life depends on materials, coatings, mounting, and environmental factors.

Q9: How heavy are aluminum traffic signs compared to other materials?

A9: Aluminum signs are around 30-40% lighter than steel signs of equal size and up to 70% lighter than fiberglass. This facilitates a more straightforward installation. Lightweight, durable, weather/corrosion resistant, recyclable, easy to customize, and visible from all angles.
