For intricate castings with delicate designs, finishing is an important process, however; cast iron manhole covers do not require excess finishing except removing the frames, runners and risers. The bearing surfaces can be shot-blasted and machined to ensure that it lies flat in the frame.
Uses of Manhole Covers
Manhole covers are used wherever there is a manhole, simply because the hole needs to be covered up to prevent accidents and to protect the public from harmful gasses, fumes, heat, high voltage and explosions. Cast iron manhole covers are preferred because they are heavy duty, strong, long lasting and are not dislodged easily. Plain and decorative manhole covers are used depending on where they are to be installed. Manhole covers are commonly known to be used to cover manholes for water drains, sewer drains, electric cable trenches and telecommunication lines. They can also be used as decorative additions to driveways, yards and walkways. Manhole covers are also used for industrial application such as for storage tanks and silos, surge tanks, for road tankers carrying petroleum and acid, pressure vessels etc.

Stainless steel is a durable and corrosion-resistant material that is widely used in the manufacturing of repair clamps. The properties of stainless steel make it an ideal choice for various applications, especially in environments exposed to harsh conditions such as moisture, chemicals, and extreme temperatures. The resistance of stainless steel to rust and oxidation ensures that repair clamps remain reliable over time, reducing the frequency of repairs and replacements.

Urban planners and civil engineers recognize the importance of manhole covers in the broader context of city design. They are crucial in planning drainage systems to prevent flooding and manage stormwater. In heavy rainfall, well-designed drainage systems, complete with properly placed manhole covers, can help channel excess water away from streets and residential areas, reducing the risk of flooding. Thus, the strategic placement and design of manhole covers are significant components of effective urban drainage planning.

2. Lubrication Apply lubricant to the stem and threads to ensure smooth operation and prevent seizing, especially in older valves.

Crash rated bollards are cylindrical posts specifically designed to withstand and mitigate the impact of vehicles. Unlike standard bollards, which can be decorative or functional in a less demanding context, crash rated bollards are engineered to specific safety standards. They are tested to ensure they can absorb and dissipate energy from a collision, thus preventing vehicles from penetrating sensitive areas, such as pedestrian zones, government buildings, and entertainment venues. These ratings typically indicate the speed and weight of a vehicle that the bollard can withstand, providing measurable assurance of its effectiveness.
