For some applications, a rigid frame is required – for example, if a forklift, it is used aside, or if it is towed to a part of a train and a relatively high speed. In these and similar cases, we recommend using our square frame system as a base. Of course, it is modular, the components of high-quality welded steel and are easily combined with the pipes and joints to form a hybrid pipe racking system that is flexible, strong and slightly modified at the same time.
