If in the past manhole covers were only known for their black color, heavy weight, and monotonous standard shapes, now their appearance is much more varied and modern. The development of material technology has made manhole covers no longer dependent on heavy and easily rusted cast iron or concrete.

One of the latest innovations is the use of BMC (Bulk Molding Compound) material for manhole covers. This material is not only lighter, but also has high durability against heavy loads, corrosion resistance, and is safe from the risk of theft.

Advantages of BMC Material Manhole Covers Compared to Conventional Materials

• Lighter than cast iron or concrete, making the installation and maintenance process easier.
• Does not rust, making it more durable and does not require special maintenance.
• Anti-theft because it has no resale value as scrap metal.
• Can be customized in color, shape, and design according to the needs of the area or environmental aesthetics.

Functions of Colors on Manhole Covers

The use of color on manhole covers is not only for visual beauty but also has specific functions according to the installation area. Here are some examples of their application:

• Yellow is usually used in pedestrian areas or public facilities to make it easily visible.
• Green is often installed in parks or green environment areas.
• Blue is associated with water installations or pipe networks.
• Gray or black is used in general areas or highways.

The development of manhole cover designs and materials today is an answer to modern needs that prioritize aesthetics as well as safety. Not only functioning as a channel cover, manhole covers have now become part of urban design that supports safety, comfort, and environmental beauty.

It is time to choose manhole covers that are not only strong, but also have high aesthetic value and are adapted to the needs of the installation area.
