No single coating that can protect every pipeline from corrosion for all conditions. Finding the appropriate coating for each application can be challenging. But asking the right questions can help you find the product offering the best long-term performance.
If you are looking for more details, kindly visit Dashang.
To identify a coating for the job, understanding the project requirements and performance needs are key parts of the process. Here is a list of questions you should ask:
- Atmospheric condition: Is the application above or below ground?
- If above ground, will the coating be exposed to UV?
- If buried, what is the condition of the soils or back fill? How quickly will the pipeline be back filled?
- Condition of the substrate or the existing coating. Which surface preparations are allowable methods?
- Is the existing coating well-bonded, and will it accept subsequent coatings?
- Are there limitations as to which surface preparation methods, such as sandblasting or grinding, are allowed at the site?
- Is the pipe dry or can it be dried?
- What is the diameter of the pipe?
- What is the service temperature of the pipe?
- What are the environmental conditions that will be present during the application?
- t emperature
- r elative h umidity
- other?
- Are there irregular shapes or details (flanges, tees, ) in the pipe?
- Is there an atmospheric &#;transition&#; area from below to above ground? Is additional mechanical protection needed for protection at the freeze/thaw line?
- Is protection needed from lawn mowers, string trimmers, and the like?
- Will the coating be applied by maintenance staff or an industrial coating contractor?
The responses to these questions should be evaluated to determine the proper coating for the application.
When it comes to selecting the right type of metal mesh for a project, there&#;s a multitude of options available, each with its distinct characteristics and applications.
Among these, epoxy coated black metal mesh stands out with our customers for its strength, durability, and aesthetic appeal.
This comprehensive guide dives deep into the process of how black epoxy steel woven wire mesh is made, its primary uses, and why it&#;s often the preferred choice over other metal meshes.

Let&#;s get into it&#;.
Creating epoxy coated black metal mesh is a process that begins with the base metal, which is usually steel, which is coated with epoxy. In order to form the mesh, steel is used since it is known for its high tensile strength and durability.
Selection of Base Metal
- Steel Selection: In order to begin the process, high-quality steel must first be selected. In the case of epoxy coated mesh, the steel is ordinarily in the form of wires, chosen according to their thickness, which in the case of wire mesh is typically around 0.7mm in thickness.
Weaving Process
- Weaving the Steel: As soon as the steel wires have been selected, they are then woven into a mesh. As a result, specifications such as mesh count, wire thickness, and hole size come into play in this process. There are 8 holes per linear inch in our epoxy coated black metal mesh, which translates to 64 holes per square inch, which is a mesh count of 8 holes per linear inch. There is a precise weaving process that ensures uniformity in the size and spacing of the holes, which in this case, is a 2.47mm aperture.
Epoxy Coating Application
- Applying the Epoxy Coating: Upon weaving the mesh, the mesh is then coated with epoxy, which is a critical step in making the mesh durable. In order to harden the epoxy resin, the mesh is passed through a bath of epoxy resin, which is then cured (hardened) using heat. Besides giving the mesh its characteristic black color, this coating also adds an additional layer of protection against elements such as moisture and chemicals, enhancing the mesh&#;s corrosion resistance to the elements.
Quality Checks
- Inspection and Quality Control: In the final stage, a thorough quality check is carried out. A thorough inspection of the mesh is conducted to determine parameters such as the uniformity of the weave, the consistency of the epoxy coating, and the overall structural integrity of the mesh.
Due to the heat involved, it is common for the mesh to bow and deform. This always triggers a rejection of the material.
As always, thank you for checking out our blog. We hope that this helps you with your project. We try to launch a couple of new guides every week. Eventually we will have covered everything there is to cover about mesh.

Our goal for our blogs and help guides is to answer as many questions as possible to help to explain the possibilities of mesh to our customers.
