Frequently Asked Questions
What size are these blank magnetic sign sheets?
Each magnetic sign blank measures 24 inches wide by 18 inches tall. This is equivalent to 2 feet wide by 1.5 feet tall.
Are 18" × 24" magnetic signs suitable for vehicle doors?
Yes. The 18" × 24" size is commonly used for business signs on trucks, vans, and service vehicles. Measure the available flat area and test the vehicle panel with a household magnet before ordering.
Will these magnetic signs stick to all vehicles?
No. Magnetic signs only attach to magnet-receptive steel surfaces. They will not adhere to aluminum, fiberglass, plastic, glass, or carbon fiber panels. Some vehicles also have a combination of steel and nonsteel body panels, so testing the exact installation area is important.
Can I print directly onto the magnetic sheet?
Standard white magnetic sheeting is designed for compatible wide-format inkjet printing and sign-making applications. Always confirm that the material is compatible with your printer, inks, and production process before printing.
Can blank magnets be used for sublimation or with a heat press?
No. These blank magnets are not suitable for sublimation or heat-press applications. They are made from flexible vinyl and rubber magnetic sheeting, which can be damaged, warped, or melted by heat. They also do not have the special polyester coating required for sublimation printing.
Which magnetic material works with dry erase markers?
Only the Indoor Dry Erase White magnetic material is dry erase marker receptive. Standard white, metallic, and reflective materials are not intended for use with dry erase markers.
Can the dry erase magnetic sheet be used outdoors?
The Indoor Dry Erase White option is intended for indoor applications such as steel doors, lockers, filing cabinets, scheduling boards, warehouse labeling, and other compatible steel surfaces.
Are reflective magnetic sign sheets available?
Yes. Reflective magnetic material is available for signs that need greater visibility when illuminated at night. Select the appropriate reflective option when ordering.
How thick is the magnetic material?
These blank magnetic sign sheets are made from durable .030-inch-thick magnetic material with 14 poles per square inch for reliable holding power on compatible steel surfaces.
