Testimonials

Philip G Manager, Substation Projects, PMP, Avangrid (USA)

I worked with Locweld on the Tower Project down at Chops in Maine. They provided exceptional customer service saving the project lots of time and money. They offer design services in-house including detailed design. Their sales team is responsive and very good to work with.

V.H. Tx Lines Program Management, (Canadian Utility)

Just wanted to pass on the kudos and thank you for the super quick turnaround for our pieces of steel. Our guys were able to complete the work in the allotted outage window. I have now seen first-hand why our Construction crews love dealing with Locweld. Please keep up the great work!

Pat M. Senior Foreperson, Tx Lines Eastern Zone

Your promptness in response as well as ability to correct issues is greatly appreciated by all of us in the field and planning division.

Jeff E. Lead Engineer, Transmission Line Engineering (USA -Large Southeastern utility)

Our utility was in a bind. We needed about 30 towers (115kV and 230kV tangents and dead ends) made in about 6 weeks. Locweld stepped up for us. They took our old hand drawn drawings and fabricated and shipped over 1 million pounds of lattice steel to meet our deadline. I was really impressed with their manual conversion of drawings. There was only 1 steel member where holes were incorrectly punched. Locweld replaced that member within a few days. Locweld rose to the challenge for us.

Ian K. Civil/Structural E.I.T. (USA)

I cannot thank you enough for your job well done. Everything from your work ethic to good faith attitude truly left a great impression on us. In my opinion, you will come highly recommended for future work & I look forward to it.
