The design of the sliterium industry product analyses the mechanics of the product at the time of its use, designing a spinal lock structure that is decentralized, dynamically resilient and softly supported. The new architecture designs are mutually stretching and weighting each other, so that the product is light in weight and meets standard standards, and corresponds to the pre-responding requirements of the ground and floors, making it safer to connect the entire stairwell to the residential structure. The slita ladder industry products were designed with due regard to the convenience of the product when installed and dismantled. The traditional stairwells are heavily used in heavy materials, semi-casting and on-site collage. Processes are often welded, welded, decomposition heavy and are destructive when again decomposition. The sliter plateau industry uses a large number of high-tech light material components, and the process uses a modular fusion set that requires a combinatio...
