Sizes other than these may be special ordered, with the prices being the same as the next larger standard size (minimum order 50 signs for other sizes). Various rounded corners available at extra cost. Click here to see the different size rounded corners we offer. Our signs may be attached To our Frame Style stakes or our Flat Plate Style stake to which customers may attach the sign using whatever method works best for them. All our stakes have a 135° bend at the top. Sign holders (stakes) are ordered separately, or the sign plates may have holes drilled to customer’s specification if desired and not ordering the sign holders.  Galvanized steel stakes are far superior to aluminum stakes which can corrode away in a few years.  Signs are made of heavy-duty 1/8″ thick laminated UV and weather resistant plastic material. Colors available are: Black textured surface with White letters, White textured surface with Black letters, Forest Green glossy surface with White letters, Apple Green matte surface with White letters, and matte Red with White letters. About 60% of our customers order black signs with white text, 20% order forest green signs with white text, 10% order white signs with black text, and 8% order apple green signs with white text, and 2% order the red sign plate with white letters. As to the use of italics for the scientific names, about half of our customers order their signs with italics and half prefer non-italicized text, as a matter of personal preference.  For security, stakes may be set in concrete. See our picture section or our Facebook page for pictures of many of our different sign sizes, colors and stakes. Because of the wide variation in tree trunk sizes, texture, etc., we do not sell screws and/or springs for mounting signs without stakes on trees. These materials are best obtained locally and will vary considerably depending on your application. Signs are engraved to your specifications with your text on our computerized engraving machine, using the layout you desire. Common items included on signs are genus, species, common name, family and country of origin, or code number referenced to your brochure. Fonts are scalable and text may be italicized where desired. See our brochure for a comparison of the two types of sign support stakes we offer. Again, the signs and the support stakes are sold separately.
