EN13101 Polypropylene Cover Core Manhole Steps: Guardians of Underground Space Security

As a key component connecting the ground and the underground, the safety and durability of the Manhole Step are of vital importance.EN13101 plypropylene cover core manhole steps strictly adheres to European standards and, with excellent performance and reliable design, is ideal for underground works.

1. Standards, specifications and product composition

The EN13101 standard strictly stipulates various indicators of the entrance steps of underground pedestrian passages to ensure product quality and safety. The metal core can be made of carbon steel, 304 stainless steel, 316 stainless steel or galvanized ductile iron, etc., to provide the foundation strength for the step and ensure its load-bearing performance. The external polypropylene coating endows the step with unique advantages and enhances its overall performance.

2. Performance advantages

High visibility ensures safety: The eye-catching colors are extremely prominent in the dim underground environment, providing a strong guarantee for the personal safety of the workers.
Anti-slip design for complex environments: The special anti-slip design on the surface can generate sufficient friction with the sole of the shoe in damp, muddy and other harsh conditions, ensuring the stability of personnel during the climbing process.
Strong corrosion resistance: The chemical stability of polypropylene enables it to resist corrosive substances such as acids, alkalis and salts. It can maintain structural integrity for a long time in complex environments such as underground sewage and groundwater.

3. Scientific design features

Interlaced ends enhance stability: EN13101 plypropylene cover core manhole steps step ends are arranged in an interlaced pattern to increase contact area with the support structure, effectively distribute human weight, improve grip strength, reduce wobbling during use, and further enhance safety.
The foot pedals enhance the user experience: The design of the foot pedals provides a wider stepping area, adapting to the different foot sizes and standing postures of users, and improving comfort and stability during the climbing process.
Rich size specifications: To fit various manholes, the steps offer multiple size options. The common length ranges from 185mm to 343mm, the width from 135mm to 229mm, and the height from 40mm to 59mm. There are also various specifications for the support spacing to ensure wide applicability.

4. Convenient installation and maintenance

(1) Easy and efficient to install
The installation of these steps is relatively convenient. When newly built, they can be directly embedded in the manhole structure and fixed with concrete, anchor bolts, etc. The existing structure can be installed with the aid of special accessories without large-scale renovation, thus saving construction time and costs.

(2) The key points of maintenance are clear
Daily maintenance mainly checks the wear of the coating, the rusting and deformation of the metal core, and the fixation condition. If the coating is found to be damaged, it should be repaired in time. If the metal core rusts, rust removal and anti-rust treatment should be carried out. At the same time, the debris on the surface of the step should be cleaned to ensure that its performance is always in good condition and to extend its service life.

EN13101 plypropylene cover core manhole steps, with standardized design and scientific structural features, become an important guarantee for the safety and convenience of underground space, will continue to safeguard all kinds of underground operations.
