The overall layout is rather nice looking. You just need some more content. At a brief run through your site, I see that most of your content is photos. Since the purpose of this web site is to act as an big brochure, you need to be a lot more verbose. The web site needs to sell the company. Right now it's mainly a photo album.
Does the company publish an annual report? If so, get them. They'll give you lots of ready made verbage to copy over.
A time line of the company's history is always interesting reading.
Include a page of the company's executives - portrait and brief resume type biography. It'll give a "face" to the company.
Speaking of faces, all your photos are of hardware. Toss in some shots of the people doing the work. Show the men and women of McEvoy working hard and flashing smiles of pride with their work.
Assemble some customer testimonials to fill a page.
Assemble a few pages of write up describing how "good" steel fabrication, engineering, welding, pipe work, etc is "supposed" to be done. Educate the customer while subliminally giving them the impression that McEvoy knows their stuff while all those "other" companies are just out to screw over the unsuppecting.
