AssureaKote™ Poly Coated U-Bolts
Step-Ko Products AssureaKote™ coating technology is a special proprietary coating that has superior temperature and physical properties when applied to various types of u-bolts. The AssureaKote™ coating provides excellent protection from corrosion by preventing metal to metal contact between the u-bolt and piping. The AssureaKote™ coated u-bolt is very versatile and can be used in many industries including but not limited to pipelines, refineries, chemical plants, offshore platform, rigs, paper mills, and in marine applications.
Step-Ko Products keeps a wide variety of sizes of AssureaKote™ u-bolts in stock for immediate shipment in standardized box quantities. All the AssureaKote™ U-Bolts in sizes 24” and below are packaged in a strong durable poly bag with the u-bolt, 4 nuts and rubber pad for easy application in the field eliminating the removal of the nuts from the u-bolt before applying to the piping therefore eliminating unneeded labor time. When the AssureaKote™ is coupled with the AssureaPad™, a special blended thermal plastic half round or round pad, you can reduce the possibility of crevice corrosion or water formation under the pipe therefore giving the secure feeling that your piping is protected.
