The load bearing in structure forming the exterior of the theatre is firmly bolted to the building to achieve total stability. As such, every wall plate is sturdily supported, making it possible to append additional devices afterwards. Plates and integral structures are bolted together. The rigidity of the interior casing is therefore greatly enhanced. The effect achieved through the technology of bolted joints is more reliable and durable than spot welded joints. Metal stuffing is filled to the junctions. Smooth, seamless and airtight effect is accomplished by meticulous polishing work that follows. All corners in the Operating Theatre are designed for easily cleaning and sterilizing.
