Coldwell-Wilcox Technologies would love the opportunity to supply you with highest quality wastewater gates in the business. CWT is definitely “or equal” on all specs and one of our specialties is overseeing large projects from the design/submittal phase to the final installation. Our seal system the, “ULTRA-Super” is trademark pending and that is one of the many things that separates our stainless-steel CWT gates from others. Our customer service and responsiveness is the best in the business. CWT has 2 CWT’s on staff to make sure that the weld quality is a standard of excellence. CWT is completely American made, including our castings, as we are partnered with a domestic foundry. It is very important to CWT that we follow the American Iron and Steel Act. If you have any questions, concerns or comments please feel free to contact anyone on the CWT team.
