The following is a description of the plastic steel ladder:
Material composition: The outer layer is made of high-strength engineering plastic, usually copolymer polypropylene plastic, which has the characteristics of high temperature resistance, high humidity, resistance to deformation, and resistance to detachment. Embedded high-quality round steel or threaded steel, such as Jinan Iron and Steel Group's round steel or threaded steel, with a diameter of generally 16mm or 20mm.
• Performance characteristics
Strong durability: It has good corrosion resistance and can resist chemical substances such as ultraviolet radiation and acid and alkali erosion. It can be used for a long time in an environment of -15-100 ° C, with a service life of up to 50 years underground and 20 years above ground.
Safe and reliable: Beautiful appearance, good anti slip performance, high impact resistance, stable structure, strong load-bearing capacity. Some parts are also equipped with safety handrails and anti slip locks, which are non-conductive, fire-resistant, and heat-resistant, ensuring the safety of users.
Easy installation and maintenance: The installation is simple and fast, and can be directly embedded into the wall through pre installation. The surface is smooth, not easy to accumulate dust, and it can be washed with water regularly. It has strong anti-aging ability and reduces the trouble of frequent replacement.
Application scope: Suitable for various inspection wells, water towers, civil defense engineering, slope subway tunnels, industrial and civil buildings, etc. as fixed up and down stairs, especially widely used in sewage inspection wells, cable wells, sand wells and other well environments.
