E-Ties® are made from renewable resources

Treated with non-restricted use wood preservatives.

Cradle to grave – can be reused or used as fuel at end of life

If you’re looking for green solutions for railroad crossties, switch ties, bridge timbers and pilings, Nisus Corporation has the answers. We manufacture copper naphthenate under the QNAP® brand and a Disodium Octaborate Tetrahydrate (DOT) borate wood preservative under the Cellutreat® brand.

QNAP can be used as a stand-alone or as a dual treatment with Cellutreat. Cellutreat can be used as a dual treatment with QNAP or creosote. Both are EPA-registered “general use” preservatives and standardized by the American Wood Protection Association (AWPA). Let us show you how these products can create a greener tie and timber program for your company.
