TESTIMONIALS

We have been using GCS for years now and could not be more impressed with their commitment to quality and customer service. We train approximately 8,000 Union Laborers annually and our product needs can be demanding. GCS is always able to accommodate our needs even on short notice and their product line continues to expand, which offers us unlimited options

We at Bartkowski Life Safety have been using GCS as a material vendor for the past five years. The employees at GCS are committed to customer satisfaction. As a smaller company, with over 35 projects ongoing, there are times where we need a quick turn around on our orders. GCS has always gone above and beyond to ensure that material makes it to our warehouse or job site in a timely fashion.
