Columbia Marking Tools has developed a complete new line of durable concrete hand stamp characters for marking wet concrete. A standard character set includes the numerals 0 through 8 (6 is also used as 9) and a + sign. The character stamps are first machined from solid brass billets on precision CNC machine tools. Additional precision handwork is performed to create the necessary sharp corners that are required for the production of clear impressions. The characters are designed with beveled angles to enhance the release of the stamp from the impressed concrete.
Standard stamps have 3-inch characters that are 3⁄8-inches deep with a Gothic character font. Each stamp is designed with a rubber-coated metal handle. Special designs in any type of character size and font are available. Typically, users submit their rough stamp ideas and Columbia creates an engineering drawing of the stamp for approval prior to manufacture.
