Grav plate

Grav plate is a plate that emits an Artifical Gravitational Field that is commonly used to secure cargo during transportation. It is originally a Xi'an technology but it was introduced to humanity and revolutionize the shipping industry. It is constructed of a special material that emits gravity when exposed to the gravitons fed by the piping system. In most instances, the grav plate is installed under the floor, but perhaps more industrial areas would use the grav plates as the floor itself.
