Manhole covers are a removable cover that serves as a lid to close the manholes. Traditionally, manhole covers were made of cast iron, concrete, or even a combination of the two. These materials are preferred due to specific qualities like durability, inexpensive, and heavy enough to stay in place. However, technology has led to various alternative manhole cover materials like composite, fiberglass, and plastic.

Bollards, often overlooked in the grand design of urban landscapes, serve a crucial role in road infrastructure and urban safety. These short, sturdy posts are strategically placed along roadways, sidewalks, and pedestrian areas for a variety of functional purposes, ranging from traffic management to security enhancement. As urban areas become more congested and complex, the importance of bollards only continues to grow.

Applications of Bollards

1. Quick Fix for Leaks One of the main advantages of using a repair clamp is the speed with which it can be installed. Rather than cutting out a damaged section of pipe and replacing it, homeowners can simply place the clamp over the leak and tighten it, creating a secure seal.

...in the several weeks beginning in mid-February 2004, when, slowly at first but with mounting velocity, manhole covers started to disappear from roads and pavements around the world. As Chinese demand drove up the price of scrap metal to record levels, thieves almost everywhere had the same idea. As darkness fell, they levered up the iron covers and sold them to local merchants, who cut them up and loaded them onto ships to China. The first displacements were felt in Taiwan, the island country just off China's southeast coast. The next were in other neighbors such as Mongolia and Kyrgyzstan... Wherever the sun set, pilferers worked to satisfy China's hunger. More than 150 covers disappeared during one month in Chicago. Scotland's great drain robbery saw more than a hundred vanish in a few days. From Montreal to Gloucester to Kuala Lumpur, unsuspecting pedestrians stumbled into holes.
