Most frequent ready-made market offers feature individual industrial computer workstations. Individual solutions are available in plenty of sizes, shapes, colors and materials. Traditionally, industrial workstations are produced of durable and reliable material, such as steel. Frame workstations are easy to take care of, but they may be effectively exploited only on fully protected premises. Wire computer workstations are designed to prevent the dust and dirt settling on shelves. Welded computer workstations are completely secure constructions that keep the equipment absolutely safe and undamaged even in the most extreme conditions. Although all of the above may be either stationary or portable, the latter are usually preferred for interactive production sites. Equipped with rigid or swivel casters, mobile computer workstations easily maneuver and roll from site to site even when fully loaded. Usually they roll on 4 wheels, two of which have brakes for secure standstill. Stationary computer workstations are the best option when there is no need to move the computer around to fulfil the tasks.
