About 16mm DIa TMT Bar PVC Rungs
PVC Foot Steps (PVC Encapsulated Rungs) are safety ladder steps used in underground water tanks, manholes, sewage systems, and wells to allow safe entry and exit.
What are PVC Foot Steps?
PVC Foot Steps are steel bars (usually TMT bars) fully coated or encapsulated with high-quality PVC material. This makes them corrosion-resistant, strong, and safe to use in wet environments.
Main Components
-
Core Material: Mild Steel / TMT Bar (commonly 12mm, 16mm, or 20mm dia)
-
Outer Coating: Virgin PVC (anti-corrosive)
-
Design: U-shape or L-shape for firm grip inside concrete walls
Common Sizes
Key Features
Anti-corrosion & rustproof

How It Works / Installation
-
Steps are embedded in concrete walls at equal spacing (usually 250300 mm).
-
The steel core provides strength, while PVC gives protection and grip.
-
Workers use them like a ladder to safely go inside tanks/manholes.

Certified Quality and StrengthComprehensive compliance with IS 10910 and IS 1786 standards underscores the reliability of these PVC rungs. With a TMT bar core exceeding 415 N/mm2 tensile strength and a load-bearing capacity over 2.5 kN, they are designed to provide exceptional structural safety and long-term reliability in demanding infrastructure applications.
Engineered for Harsh EnvironmentsThese PVC coated rungs offer remarkable resistance against acids, alkalis, and aggressive sewer gases, greatly enhancing longevity in corrosive settings. The smooth PVC surface ensures a slip-resistant, corrosion-proof grip, while maintaining surface hardness between 60-80 Shore A. This makes them ideal for both cast-in-situ and precast installations.
Versatile Application and InstallationWith a standard length of 260mm and a 16mm thickness, the rungs seamlessly fit into RCC manholes, sewer, and water chambers. Their design enables ease of installation during both construction and retrofitting. Lightweight at approximately 450g, they're practical for use by manufacturers, dealers, fabricators, and other industry professionals.
FAQ's of 16mm DIa TMT Bar PVC Rungs:
Q: How are the 16mm Dia TMT Bar PVC rungs typically installed in chambers?
A: The rungs are installed either in cast-in-situ or precast RCC manhole, sewer, or water chambers. They are embedded during the construction process to ensure secure and durable placement.
Q: What are the primary benefits of using these PVC rungs in manholes and sewer chambers?
A: They offer high corrosion resistance, superior durability, slip resistance, and excellent mechanical strength, ensuring long service life and safety for maintenance personnel in harsh or chemically aggressive environments.
Q: What makes the 16mm TMT Bar PVC rung suitable for chemically aggressive environments?
A: The PVC coating provides high resistance to acids, alkalis, and sewer gases, helping the rungs withstand corrosive environments and maintain structural integrity over time.
Q: Where are these PVC rungs commonly used?
A: They are predominantly used in RCC manholes, sewer chambers, and water chambers across municipal, industrial, and commercial infrastructure projects.
Q: What is the process for ensuring that the rungs conform to IS 10910 and IS 1786 standards?
A: Each rung is manufactured using approved materials and tested for tensile strength, dimensional accuracy, and chemical resistance to meet the requirements of IS 10910 and IS 1786. Quality control checks are performed at multiple production stages.
Q: What usage precautions should be considered during the installation of these rungs?
A: Ensure correct embedding depth within concrete, proper alignment, and secure anchoring. Avoid mechanical impacts that could potentially damage the PVC coating before or during installation.
Q: What is the working temperature range for these PVC rungs?
A: They are designed to function reliably in temperatures ranging from -10C to 60C, making them suitable for diverse climatic and site conditions.
