Nice to meet you. I've submitted a few versions of the same basic concept: three mount-like (triangular), abstract shapes coming together to make one larger geometric shape. This symbolizes unification of separate parties, into one cohesive unit.
The colors I've used are consistent with your request for use of grays, blues, and blacks. I've also used green to symbolize wealth and power, and orange to symbolize your clientele itself: commercial and industrial companies, contractors included.
In ancient times, the pyramid was a source of power and architectural genius. The shape that is formed by the three separate shapes coming together may also be viewed as though one were looking down at one of the great pyramids of Egypt; the shape becomes three-dimensional in that respect.
