The MILD STEEL PVC ENCAPSULATED RUNGS STMS027 are high-quality manhole steps engineered to meet the rigorous European Standard EN13101:2002 for underground man entry chambers. These manhole steps feature a 12 mm diameter steel rod core made of Grade SAE 1018, fully encapsulated in durable polypropylene (PP) to provide unparalleled protection against corrosion. The robust encapsulation makes these rungs spark-proof, polymer-covered, and UV stabilized, offering superior resistance that exceeds international benchmarks. Each rung boasts a unique step design with a 165 mm width and 275 mm length, where 145 mm of the length is designed for secure grouting inside walls, ensuring firm installation and enhanced safety. These steps offer high impact resistance with no sharp edges or corners, and their anti-slip surfaces offer excellent grip and lateral slipping protection. The outer size of 22 x 25 mm (±1 mm) and precise dowel distance of 145 ±1 mm enhance compatibility with standard manhole dimensions. With a product weight of approximately 0.800 kg, these rungs are both lightweight and cost-effective, delivering standalone strength with pull-out loads of around 230 kg, compression loads up to 430 kg, and a maximum load capacity nearing 575 kg. These attributes ensure superior durability and safety in underground manual access chambers, making the STMS027 model a preferred choice for utility companies, infrastructure projects, and construction professionals requiring reliable manhole entry solutions.
