Since the price of sewer manhole covers is high and cast iron manhole covers have been frequently reported as stolen, manhole covers have been made from newer materials to eliminate the possibility of theft. An important feature of theft-resistant manhole covers is that their materials cannot be melted down and sold, which makes these covers theft-resistant.
Introduction to Types of Theft-Resistant Manhole Covers
There are various types of theft-resistant manhole covers, providing you with different options.
Concrete Theft-Resistant Manhole Covers
The concrete theft-resistant manhole covers from ABtank are characterized by high resistance and weight, making them suitable for manhole covers. However, this type of cover also has some drawbacks. For instance, the high weight can be challenging for workers during handling. Additionally, they have some degree of brittleness and are prone to cracking under impact, though they do have their own unique advantages.
Composite Manhole Covers
This type of composite manhole cover is considered one of the theft-resistant options available on the market, offering high impact resistance. Additionally, their high weight makes them less susceptible to theft.
Nanocomposite Manhole Covers
These manhole covers are among the most advanced types available. Nanocomposite manhole covers are resistant to heat, flames, UV rays, impact, and many other factors, making them known as the best manhole covers. Nanocomposite covers have a very low risk of theft because the materials used in them can only be recycled using industrial equipment. Therefore, these covers not only are not recyclable but also have high impact resistance, which prevents them from breaking under impact.
Valve Manhole Covers
The theft-resistant valve manhole covers are made of compressed plastic (copolymer) and have various applications across different industries. These covers are highly secure against theft and offer high resistance and durability. Some of the advantages of these covers include:
-
- The valve manhole cover is theft-resistant.
- It has excellent resistance to pressure.
- It is resistant to UV rays from the sun.
- It resists corrosion.
- It is resistant to groundwater, saltwater, electric currents, and flowing electrolytes.
- It has a high installation temperature range.
- It is compatible with any type of manhole cover.
- Long lifespan.
- …
In general, manhole covers come in various types, and theft resistance is limited to certain types. However, using a theft-resistant manhole cover is crucial for protecting these covers. Each type of manhole cover from ABtank has different specifications and prices, and the price differences sometimes lead to the purchase of lower-quality types that may not provide adequate security against theft.
