The fiberglass manhole cover from Istapolymer Sharif has a complex structure made of thermoset resin-reinforced fibers, calcium carbonate, unsaturated polyester resin, peroxide, silica fibers, and color pigments. This network structure provides high resilience and resistance, showing remarkable endurance against damages that easily destroy other manholes. Tests conducted by scientists and technicians have confirmed the high durability of these covers.
Advantages of Fiberglass Manhole Covers
Fiberglass manhole covers were developed as a replacement product due to the drawbacks of cast iron manhole covers. The fiberglass manhole cover does not suffer from any of the deficiencies of metal covers. In addition to being rust-free, rot-proof, and unbreakable, it also offers other advantages:
- High mechanical resistance.
- High hydraulic and chemical thermal resilience.
- Resistance to corrosive and erosive chemicals.
- Ability to easily withstand traffic loads.
- High impact resistance.
- Excellent resistance to freezing, thawing, saline water infiltration, groundwater penetration, and damage from electrolytic and electrical currents.
- No noise pollution when vehicles pass over it.
- UV resistance.
- One important feature with high economic value is its theft resistance.
High Stability of the Cover
If we want to examine the key advantages of fiberglass manhole covers compared to other covers, the high stability of these covers is significant. Traditional covers, such as concrete ones, would quickly fragment under heavy traffic and high vehicle pressure during peak hours. In contrast, fiberglass offers suitable resistance to these pressures. Additionally, due to the classification of composite manhole covers, their strength can be adjusted by modifying the cover’s composition.
Conducting Stability Tests
The fiberglass manhole cover has undergone numerous tests, including force tests, fatigue endurance tests, scratch resistance tests, abrasion resistance tests, thermal stability tests, resistance to automotive fuel tests, and UV resistance tests. This product is reliable and does not impose unnecessary costs on the national economy. Therefore, it can be considered a national product designed to reduce country-wide expenses and eliminate additional costs from the country’s economy.
Price of Fiberglass Manhole Covers
As mentioned, these covers are offered in different classifications. For example, traffic and non-traffic covers can withstand various pressures, with differing compositions of raw materials. Therefore, the price of fiberglass covers will vary. These covers and sewage covers can also be manufactured in various shapes, such as circular or rectangular. Different sizes and dimensions can also affect the final price. Additionally, ABtank offers options for selecting the color and printing organizational logos on the fiberglass cover, which also influences the final price.
