1. The seat is a hollow blow-molded conjoined chair, made of high-quality polyethylene (PE), and made of a hollow structure using a blow molding process. The overall design of the seat should follow the ergonomics, fit the curve of the human body to the maximum, and reduce sitting fatigue. The seat has superior mechanical properties, high strength, impact resistance, safety, good weather resistance, stable chemical properties, acid and alkali resistance, antistatic, abrasion resistance, water repellency, and stable color. The design, shape and installation method of the seat should conform to the international common technology, which is beautiful in appearance, comfortable to sit on, and easy to install, maintain and manage.
2. The seat foot frame is made of high-quality aluminum alloy precision die-casting or high-quality steel. The surface is phosphated and then electrostatic sprayed. The foot frame is on the side of the concrete step with special fasteners. Each fastener can withstand a tensile force of 1000kg Above (C25 concrete), the installation method is suspended installation.
3. The size of the seat is 315mm in back height, 450mm in depth, 415mm in width, and 500mm in center distance between seats. The connecting pipe of the seat is ¢32×2 mm thick high-quality hot-dip galvanized pipe.
