Pro-Coat U-BoltsAbout the Dale Comany

The Dale Company manufactures high-quality Pro-Coat U-Bolts™ for industrial applications. We offer custom standard and custom Pro-Coat U-Bolts™ at competitive prices, with quick turnaround and same-day shipping for many products.

Our Pro-Coat U-Bolts™ are designed to provide superior performance in corrosive and moist environments, which protects process pipe support points in refineries, chemical plants, and offshore platforms. In these environments, uncoated U-bolts and pipes corrode, leading to weaknesses in the pipe walls and leaks.

 

 

 

 

Pro-Coat U-Bolts™ are manufactured using materials that will provide a secure joint while protecting the protective coating on the pipe. The bolts can be snugly tightened to the pipe, avoiding capillary crevices around the pipe, ensuring that the pipe is protected from movement and abrasion. In addition, the coating on the bolt provides protection from heat, vibration, sandblasting, and other corrosive elements in manufacturing and marine environments.

We manufacture Pro-Coat U-Bolts™ in the following materials:

  • Carbon Steel
  • A193 B7
  • 321, 316/316L, 304/304L, 410, and 347 stainless steel

Finishes include SermaGard®, hot dipped galvanizing, zinc plating, PTFE, and polyolefin coating.
