The development of outdoor slide can be roughly divided into three stages. Today, I would like to share with you the development of the outdoor plastic slide.
The first generation slide is a product of the 1970s. Its top is made of glass fiber reinforced plastic. Its skeleton is a cheap square tube or round tube. After welding, it is painted. The top and the skeleton are directly connected with ordinary iron gongs after punching. The glass fiber reinforced plastic slide is single-layer, smooth outside and rough inside. The exposed part of the skin will itch when children play inside. The iron part: the aisle is only 40-60cm, which is relatively narrow. Moreover, it is not secure and safe, so this product has been eliminated.
The second generation slide is a product at the beginning of this world. Its top is made of double glass fiber reinforced plastic, and its skeleton is made of steel pipe. It is sprayed with paint. The top and the skeleton are directly connected with ordinary iron gongs and wires after drilling. The glass fiber reinforced plastic of this slide is double-layer hollow, smooth outside, and can be painted with many beautiful patterns. The iron part: the steel structure of column and steel plate is adopted, the column is a steel pipe with a diameter of 76cn, and the gangway steel plate is 90cm wide, a little loose. The overall structure is firm and the safety is high, so this product is still used in some places where conditions are not good. Disadvantages: FRP is easy to age, fade and crack. The steel pipe has rusted for a long time.
The third generation slide is a product after 2008. Its top is made of engineering plastic, and its skeleton is galvanized steel pipe, sprayed with paint. The top and skeleton are connected with stainless steel gongs and wires through aluminum alloy fasteners after drilling. The engineering plastic of the slide is double-layer hollow and flexible, and the rotational molding process is one-time molding. The outside is smooth, and beautiful patterns are produced at one time. The steel part: the steel structure of column and steel plate is adopted. The column is a steel pipe with a diameter of 114cn, and the gangway steel plate is 120cm wide, which is more loose. The overall structure is quite solid and the security is extremely high, so this product is often favored by some high-end users. This is the best choice for kindergartens. It is safe, durable and highly ensures the safety of children.
