All TOUGH TRAC products are manufactured in China with a certified ISO 9001:2008 rating. The factory is also on the list of highest rated factories for quality on the mainland. Quality and durability is our primary concern. All products have gone through extensive testing to meet all codes and requirements. We manufacture all our aluminum products using 6000 series alloys and we offer mill and anodized finishes. We also only use stainless steel hardware for all our bolts, nuts and washers. All of our original designs were based on CSI (Canadian Solar) panels. As TOUGH TRAC mounting systems are a perfect fit for all Canadian Solar panels, we are currently adding custom top and bottom mount clips for other major solar panel manufacturers. We at TOUGH TRAC believe in quality, durability, and afford ability. We want to produce superior products that will last and have a reputation of that our products are built tough.
