What Is a Rating Plate, and Can It Be Made as a Custom Decal?

Rating Plate Decal Questions Buyers Ask

What exactly is a rating plate, and does it need to be metal?

A rating plate is a fixed label showing operating data such as voltage, amperage, weight capacity, serial number, or compliance markings. Metal has traditionally been used because it holds up outdoors and resists wear, but it is not a legal requirement in most cases. A custom rating plate decal printed on cast or premium vinyl can meet the same durability standards as engraved metal while costing less and printing faster, as long as the underlying equipment and any specific industry regulation don't require a metal substrate.

How durable is a printed rating plate decal compared to engraved metal?

Printed rating plate decals provide strong outdoor durability, but they generally won’t match the permanence of an engraved metal plate in extremely harsh conditions. Standard calendered vinyl lasts about 3–5 years outdoors, while high-performance cast vinyl can last up to 8 years when properly applied and maintained. Protective lamination also helps resist UV fading, moisture, scratches, and everyday weather exposure.

For rating plates on generators, ATVs, boats, outdoor electrical enclosures, and other equipment, high-performance cast vinyl is a good choice when you need durable, full-color information without the weight or rigidity of metal. Engraved metal may be the better fit when the plate will face severe abrasion, high heat, impacts, or other conditions where maximum long-term permanence is required. 

What sizes and shapes can a custom rating plate decal be printed in?

Rating plates print anywhere from 2 inches by 2 inches up to large format sizes exceeding 100 inches, depending on the product line you order from, such as ATV Decals or Boat Decals. Standard shapes include rectangles, circles, and rounded corners, but die-cutting allows any custom outline that matches the panel or housing it's applied to.

What information and file format do I need to submit for a rating plate?

Send a vector file (AI, EPS, or high-resolution PDF) with the exact text, model numbers, voltage or capacity ratings, logos, and any required compliance icons laid out at the final print size. If you're not sure how to prepare artwork, our custom decal design best practices guide covers resolution, bleed, and text sizing so small print stays legible.

How is pricing structured, and is there a discount for ordering multiple rating plates?

Pricing is based on size, material, and cut option, with a minimum order of 1 unit. Bulk orders of 50 or more units move into tiered pricing, which is common for manufacturers labeling a full production run of equipment with the same rating plate design.

How long does production take, and can I rush an order?

Standard production is 3 business days. If you need plates sooner, Priority production ships in 1 business day, Express in 2 business days, and Saver production in 5 business days for a lower cost. Orders placed after 5pm CST begin processing the next business day.

How do I install a rating plate decal so it stays put outdoors?

Clean the surface with isopropyl alcohol to remove oil, dust, or residue, let it dry fully, then apply the decal using firm, even pressure from the center outward. Cast vinyl options like 3M Control Tac are repositionable before final pressure is applied, which makes alignment easier on curved or textured equipment housings.
