GSI's skills in marking wire and producing wire and cable markers are a product of over 30 years of development and production experience.  The company's reputation, started by its first customers, continues to grow.  And, what those early customers learned back in the 1960's, new users are still finding out today; GSI has no equal for quality, reliability and cost effectiveness.

In the event that space, weight or other factors rule against wire or cable markers, GSI also marks wire and cable directly with hot stamp printing.

GSI customers choose from a variety of colors, sizes and materials, Selection of the most appropriate materials and processes ensures the best performance on the job. The most widely used materials for heat shrinkable sleeve type markers are polyolefin and PVC. Both are available in forms that provide a range of flexibility or rigidity, thinness or thickness or other attributes. Other heat shrinkable tubing materials are silicones and fluorocarbons such as Kynar and Teflon.
