Flanged (Ring lock) scaffolding systems are used for jacketing or covering buildings for water and heat isolation for buildings facades and also can be used for slab scaffolding. Main parts of the system are produced from TSE certified 42x2.5 mm pipes for vertical braces, 48x2.5 for horizontal and diagonal braces, steel plank and laddered plank, end guard rail, base jack and wall tie. System can be attached easily and fast consisting ring locks, wedge heads and ledger head in the connection parts. The width/length of working area can be set by adjusting the length of horizontal/diagonal braces. Ring lock system is able to carry a capacity of heavy load due to ring locks every 50 cm on vertical braces. In order to balance the system, base jacks (spindle) are used for ground balance, head spindles of “4 Way” or “U” are used for balancing slab and beam. System is attached to building using wall ties to improve stability. Frames are produced in the factory of HALAS SCAFFOLDING by automatic arc welding machines and finally hot dip galvanized or painted by special antirust paint by automatic spray machines.
