Specifically, through our affiliates, we can provide all fabrication and assembly of skid production units, shop and field tanks, piping, etc., as well as the painting and field installation of these components. Our US FUSION affiliate is a full-service HDPE lining and piping company that provides the product, fabrication and the field installation, all internally.
