Best of the best

[DSi] is like the crème de la crème in … structural engineering.

Arol Wolford
Pres. & CEO, VIMtrek

‘Best I have ever seen’

DSi is incredible — the best I have ever seen in the industry — for the design and detailing of mid-rise cold-formed steel structures. They can look at a set of drawings and see where there will be issues.

‘DSi knows it well’

You have to have somebody who is very familiar with cold-formed steel, and DSi knows it well.
