Ceiling Grid Structure is a floor of structural steel channel or grating which extends over the upper portion of the stage house. Provides mounting positions for theatre equipment and staff access to any point over the stage for rigging and maintenance. Rigging is used to make changes in the level of the stage and adjust other accessories. Lamps, lights, fabric loads, battens, ladders, frames etc are all dependent on solidarity and engineering of rigging. This basic skeleton also allows the movement of scenery, background, lighting and even people in some cases. Motorised structures effectuate the speed and flair of suspensions through a pre-selected function. The hoists come with an enormous capacity for weight, efficient Brakes and sometimes pre-determined configuration. The entire system works on balancing counterweights, smoothening lines and making joints sturdy and strong. The mechanism is largely dependent on the initial structure which is basically formed of pipes and angles. The backstage vertical structure is hidden behind a veil and several storeys can be added on-site as needed. They make everything inherently safe, forceful, flexible in operation and most of all extensively capable of accommodating add-ons. The entire network is carefully designed to be error-free in an accurate and systematic manner. The stage grids are not only for theatres, but they can also be used in schools, halls, auditoriums and pretty much anywhere.
