This popular exhibition gantry build is ideal for use as a back drop or rear wall at any exhibition or trade show event. Here we are using our 50mm dia tube, spigot and pin system on additional 1m sq base plates. Unless you can bolt into the floor, a single arch, portal or goal post, as this design will need additional support. System 50 Trio is well suited to external events too, but banners should be made of mesh pvc banner to aid wind pressure to reduce as it travels though the ting holes of the mesh. This structure has dimensions of 6m x 2.5m high.
