our swivel gravlock girder coupler are used in pairs to enable scaffold tube and structures to be anchored to steel i beams with upto a 45mm flange capacity.
the swivel gravlock girder coupler allows tube to be used through 360degrees, forged steel construction with a zinc plated exterior for long life.
Easy maintenance.
Easy maintenance. Not easy to rust and break, maintenance is very convenient after use, which not only reduces the difficulty of maintenance, but also saves the maintenance cost, reduces the manpower and material resources of maintenance, and increases the efficiency and quality of construction.
Strong corrosion resistance.
After passivation and galvanizing, the anti-rust ability of the whole piece is greatly improved, and its service life is long, far exceeding the service life of pressed couplers.
Strong resistance to stripping.
With the new connection, the new nut ensures that the pressed couplers can be fixed vertically and firmly in the case of steel tube deformation, eliminating the possibility of steel tube slippage.
Strong anti-deformation ability.
Compared with the ordinary pressed couplers, because of the different manufacturing processes, it breaks through the limitation of the traditional stamping process on material thickness， which can completely guarantee the non-deformation in the use process, thus ensuring the safety and reuse of products.
