The flanged wedged scaffolding system is a high-capacity under-form scaffolding system with rigid connection points without requiring both a work scaffold and too many connection apparatus. When used as a work scaffold, its horizontal depths can be made in standard lengths of 70cm and any length between 1-3m. When used as an under formwork scaffolding system, it has a load carrying capacity of up to 6 tons, depending on the horizontal connection range. The posts that make up the system are produced from 48x3mm TSE certified pipes between 100 and 50cm flanges. As a rigid system is formed with the connection of horizontal and vertical elements, a scaffolding with a high load carrying capacity is provided, which is safe against buckling.
