 At present, Lide powder is mainly produced in China. Most of the domestic Lide powder production is still using traditional methods. The main raw materials are zinc oxide, sulfuric acid and barium sulfide (barite and coal are produced by high temperature reduction). Zinc 45% ~ 70%. The traditional method for producing the Liede powder process is to use zinc bakelite containing more than 45% zinc as a raw material to be leached with sulfuric acid to obtain a crude zinc sulfate solution, and then to remove iron by potassium permanganate, and then replace the heavy metal with zinc powder and filter to obtain zinc sulfate. The refined liquid is further subjected to metathesis reaction, pressure filtration, calcination, rinsing, drying, and pulverization with strontium sulfide to obtain a series of different types of lindose powder containing zinc sulfide of 30% or more. The whole process is carried out in an acidic (ra<7) environment, which consumes a large amount of sulfuric acid. The sulfuric acid has strong corrosiveness and requires high production equipment. The final discharged slag is acidic slag, which brings new pollution to the environment. High requirements, high production costs, and poor quality of the products obtained.

  • Moreover, the integration of technology in bollard design is on the rise. Smart bollards equipped with sensors can monitor traffic patterns, detect unusual activity, or even provide real-time information to pedestrians and drivers alike. These technological advancements can optimize urban mobility and enhance safety measures, providing data that city planners can use to make informed decisions about infrastructure improvements.

  • Parking bollards can also serve varied purposes beyond simply marking boundaries. Many modern bollards come equipped with additional features, including reflectivity, which enhances visibility at night. Some bollards can even be retractable or removable, providing flexibility for homeowners who may need to accommodate larger vehicles at times. This versatility makes them a smart choice for adapting to varying needs while still upholding security.


  • Manholes are also periodically placed along the sewer or stormwater line for easy maintenance access. This placement varies depending on the diameter of the sewer or stormwater system in question.

  • Customization is another essential service provided by grating manufacturers. Every project has its own set of requirements, and manufacturers often work closely with clients to develop solutions that fit their specific needs. This could involve modifying the size, material, or design of the grating to match particular environmental conditions or load requirements.


  • Moreover, carbon fiber is resistant to corrosion and environmental degradation. This means that bike racks made from this material can withstand harsh weather conditions, from intense sun to rain and snow, without deteriorating. The longevity of carbon fiber also minimizes the need for frequent replacements, ultimately saving consumers money in the long run.


  • Scrap steel is melted in a crucible, induction, electric arc or reverberator furnace at 1500° C or 2700°F. The required alloys carbon and silicon, and flux to bind to impurities to create slag are added to the molten iron. The slag is lighter than iron and floats to the top from where it is removed. The molten iron is then poured into a metal ladle with a long handle which is then carried to the sand molds contained in the metal frames and poured through the riser. Green sand has a lower auto-ignition temperature than the temperature of the molten iron allowing the organic material present in the sand to use up all the oxygen present in the mold, preventing oxidation of the manhole cover. Trapped gasses can cause bubbles in the casting.

  • The 1-1/2 inch gate valve is characterized by its size, which indicates the nominal pipe size it is designed to interface with. The valve typically comprises several key components the body, the gate, the stem, and the actuator.


  • - Wall-Mounted Racks Perfect for saving floor space, these racks attach to walls and can hold wheels at various heights. They are best suited for locations with limited horizontal room.


  • Cast Iron Manhole Cover is cast out of gray cast iron. As ductile cast iron is higher in strength, it is used for manholes that are supposed to take heavy loads ( Airport areas). The gray cast iron used for manhole cover manufacture is a combination of carbon and silicon. The carbon gives strength and durability to the element. The addition of manganese to the molten iron gives ductile cast iron.

  • One of the most pressing concerns for cyclists is the safety and security of their bicycles. Unfortunately, bike theft is a common issue in many urban areas, and inadequate parking solutions can exacerbate the problem. Bike racks play a critical role in mitigating this concern, as they enable cyclists to lock their bikes securely. The design of a bike rack should allow for multiple locking points to deter thieves. Moreover, strategically placed bike racks in well-lit and visible areas can further enhance the sense of security for cyclists, encouraging more people to take up biking as a legitimate commuting option.


  • - Water Supply Systems Used in municipal and industrial water lines to control water flow.


  • Moreover, the use of recycled plastic tree grates can significantly contribute to improved tree health. These grates allow for better access to water and nutrients while still protecting roots from foot traffic and potential damage. With proper ventilation and drainage, trees are better equipped to thrive in dense urban landscapes. This contributes to increased biodiversity and enhances the overall ecosystem, making cities more resilient in the face of climate change.


  • The two-in-one dustbin also has the potential to positively impact local economies. By enhancing recycling efforts, municipalities can reduce the costs associated with waste management. When recyclables are properly sorted and collected, they can be redirected to recycling facilities, allowing local governments to save on landfill expenses. Additionally, promoting recycling can contribute to job creation in the recycling and waste management sectors, further benefiting the community.


  • Safety is at the core of The Bollard Company's mission. They understand the potential dangers posed by traffic in urban areas, and their bollards are designed to mitigate these risks. The company offers crash-rated bollards that can withstand significant impacts, protecting both pedestrians and property. Such features make their products ideal for use in high-traffic areas, outdoor events, and places where security is a primary concern.


  • 4. Simplicity The design of the gate valve is straightforward, making it easy to operate and maintain.
