Types of Joints Between Vertical Posts & Horizontal Bearers The joints between horizontal bars and diagonal bars with vertical bars are made with tilting pins that match with the bores present on the bars. This method provides a highly strong level of structural rigidity. Component List Components used to build European H-shape frame security scaffolding. Some components are common to other scaffolding systems. Material & Certification: Manufactured in accordance with EU regulations. Tested to European standards.
