Manhole covers are a ubiquitous feature of urban infrastructure, serving as a protective barrier over access points to underground utilities such as sewer systems, water pipes, and electrical conduits. One intriguing aspect of manhole covers is their shape—almost universally, they are round. This raises the question why are manhole covers round, and what advantages does this design provide?
Moreover, The Bollard Company actively collaborates with city officials, architects, and safety experts to ensure that their products meet the latest safety regulations and standards. This collaborative approach allows for the design of tailored solutions that address specific urban challenges.
Its design, often emblazoned with city emblems or utility logos, reflects the local character and history.
In urban infrastructure, manhole covers play an essential but often overlooked role. Among the various types of manhole covers used worldwide, double sealed manhole covers have emerged as a pivotal innovation designed to enhance safety, durability, and utility. This article delves into the design, benefits, and significance of double sealed manhole covers in modern cities.
Composite (fiberglass) manholes are commonly used in applications where infiltration, exfiltration, or corrosion by hydrogen sulfide (from sewer gas) are a concern, or where structures need to be factory integrated into a manhole before placement. In these manholes, the entire underground enclosure is constructed of some composite material, in addition to the cover.
Cast iron has been a preferred material for manufacturing gully grids for several reasons. Its inherent strength and durability make it ideal for high-traffic areas where grids must endure significant weight and frequent use. Moreover, cast iron is resistant to corrosion, which is vital in environments exposed to water and various environmental elements. This longevity reduces the need for frequent replacements, making it a cost-effective option in the long run.
The production and usage of metal gully drain covers are increasingly aligned with sustainability goals. Many manufacturers are focusing on using recycled metals, reducing the environmental footprint associated with their production. Furthermore, durable metal covers contribute to longer service life, meaning fewer replacements are needed over time, which ultimately leads to reduced waste.

Furthermore, the movement towards colored drain covers aligns with a broader trend of integrating art into public spaces. Public art installations have become increasingly popular as cities look for innovative ways to enhance urban experience and foster community engagement. Colored drain covers are a small yet impactful step towards this goal, transforming mundane infrastructure into opportunities for creative expression.
