3 mm Polymetal Signs

Polymetal is an exterior sign board that is 3 mm thick. The material is a solid, recycled composite plastic core sandwiched between two sheets of aluminum. It is extremely lightweight and durable. The recycled Thermoplastic core doesn't rot or corrode. One benefit to using Polymetal is that it can be routed on the back and then bent to form a lip so that it can be installed with no fasteners on the face.

The signs are printed in full color - you can add a background, unlimited text, photographs and clip art. 

Polymetal Sizes

The maximum print size is a 4 foot by 8 foot sheet.

Product Options / Finishing Options

The standard finishing for polymetal signs is square cut. The following options are available:

  • Standard 3 mm  thickness
  • Single or double sided 
  • Square cut 

Artwork Specifications

Files that print best are .eps or .ai (in version CS5 or lower). You must convert all text to outlines to make sure the fonts come in correctly. We can also print high resolution .pdf, .tif, and .jpg formats. Typically 300 dpi or higher is suitable for banners.

We print in four color C, M, Y, K or six color C, M, Y, K, LC, LM. Please keep this in mind when submitting files for printing as color tone shifting may happen if file is submitted in R, G, B format. If there is a specific PMS color you need, please specify that to us when submitting your order so we can help you verify that the proper color mix is used (vector artwork only).

Customer supplied files are printed as they are received so we cannot guarantee color, clarity or final output as we are just printing the supplied files and have not set them up for printing.

Payment Options

All signs must be paid for prior to being put into production. We accept Visa, MasterCard, American Express and Discover cards. We also accept checks. Checks must be received before your order is put into production.

We will not charge your credit card until you have approved your proof for your order.
