It is a tuff time for clients to understand and choose why Epoxy Mesh Better Than Aluminium for Fly Screen. While aluminum wire mesh has been a popular choice for decades, epoxy mesh has emerged as a superior alternative due to its numerous benefits.

You will get efficient and thoughtful service from Dashang.

Here are some reasons why epoxy mesh is better than aluminum for fly screens:

Key Features of Epoxy Mesh over Aluminium

1. Durability: Epoxy mesh is incredibly durable, making it an excellent choice that withstand harsh weather conditions. Aluminum mesh have higher chances to cause dent, bend, or even break under pressure. While epoxy mesh is more resistant to damage, wear and tear. It is a much reliable and long-lasting option.
2. Rust-Resistance: Another significant advantage of epoxy mesh over aluminum is its rust-resistant properties. Aluminum is susceptible to rust, which can weaken the material over time and reduce its effectiveness as a fly screen. Manufacturers apply epoxy coating over stainless steel wire mesh, aluminum mesh, and mild steel mesh to make them rust-resistant and more durable.
3. Insect-proof: One of the primary application of fly screen is to keep insects out of home or office. Epoxy mesh is an excellent choice, as they have smaller woven wire mesh openings & are effective in keeping insects out.
4. Better visibility: Epoxy mesh is also a better choice when it comes to visibility. The finer woven mesh openings allow for better airflow and sunlight, making it easier to see outside. Aluminum screen are opaque, which can obstruct your view and make your space feel darker and smaller.
5. Low Maintenance: Epoxy mesh requires little to no maintenance, unlike aluminum screens. To prevent rust and maintain their appearance, you need to clean aluminum mesh regularly. Epoxy mesh is easy to clean, and you can do it with just a damp cloth and some mild detergent. Plus, it doesn&#;t require any special cleaning solutions or tools, making it more convenient and cost-effective. This is one of the major reason why Epoxy Mesh Better than Aluminium for Fly Screen.
6. Cost&#;effective: While epoxy mesh may cost slightly more than aluminum screens initially, you make a more cost-effective choice in the long run. Its durability and low-maintenance properties mean that it will last longer and require fewer replacements, saving you money over time.
7. Environmentally friendly: Epoxy mesh is also a more environmentally friendly choice than aluminum screens. Aluminum is a non-renewable resource, and its production can have a significant impact on the environment. On the other hand, manufacturers make epoxy mesh from recycled materials, and it is recyclable, making it a more sustainable option.

In conclusion, while YKM aluminum screens have been a popular choice for fly screens for years, epoxy coated wire mesh has emerged as a superior alternative due to its durability, rust-resistance, insect-proof properties, better visibility, low maintenance, cost-effectiveness, and environmental friendliness. If you&#;re looking for a reliable, long-lasting, and sustainable fly screen solution, epoxy mesh is undoubtedly the way to go.

Epoxy-Coated Steel Reinforcing Bar is covered in IS- and ASTM A775.

What precautions should I take when using Epoxy-Coated Steel Reinforcing Bar?

• Minimize damage during transport, handling, and placement.
• Repair damage using two-part epoxy coating, approved by bar supplier.
• Use plastic headed concrete vibrators during concrete placement.

What design issues should be considered if I specify Epoxy-Coated Steel Reinforcing Bars rather than black reinforcement?

The development length for Epoxy-Coated Steel Reinforcing Bar is longer. Maintain concrete cover.

Is Epoxy-Coated Steel Reinforcing Bar environmentally friendly?

Yes. Epoxy-Coated Steel Reinforcing Bar is manufactured using reinforcing bars that are made using almost 100% recycled steel.

• Epoxy-Coated Steel Reinforcing Bar can also be recycled after use.

How long will structures with epoxy-coated bars last?

Answering this question requires an understanding of the concrete, the coating, and the localized environment; however, epoxy-coated bars are routinely specified for structures with a desired 75-year design life and often for structures with a 100-year design life, given an appropriate concrete.

In environments subjected to marine or deicing salts, corrosion initiates when sufficient chloride ions reach the reinforcing steel. The time for these salts to reach the bars is dependent on the concrete permeability and the amount of cracking in the concrete as well as the exposure conditions.

The permeability of concrete depends on the water-cement ratio as well as the presence of pozzolans including fly ash and silica fume or various concrete additives that impart water resistance. When uncoated reinforcing is placed in cracked concrete, corrosion initiates almost immediately the concrete is placed in contact with the salt solution; thus, the presence of cracks will significantly reduce the repair -free life of a structure.  Epoxy-coated bars have been found to perform well in cracked concrete compared with the use of concrete modifications alone.

To optimize the design life of structures that use epoxy-coated bars it is recommended that high-quality concrete is used with an appropriate cover over the reinforcing and that cracks in the concrete are repaired.

How does the initial and life-cycle cost of epoxy-coated reinforcing bars compare with other materials?

A study was recently conducted by the University of Kansas for the FHWA and Kansas DOT that compared the life-cycle costs of epoxy-coated reinforcing steel, uncoated and stainless steel reinforcing bars in bridge decks. This study found that the initial costs of stainless steel in bridge decks was $319/yd2, compared with $189 and $196/yd2 for decks containing uncoated and epoxy-coated reinforcing steel, respectively. Thus, use of stainless steel was $130/yd2 greater than that of the deck containing the epoxy-coated bar. Life cycle costs for the epoxy-coated reinforcing steel was the lowest at $237/yd2 compared with $319 and $444 /yd2 for decks containing uncoated and stainless steel reinforcing bars. Thus, the epoxy-coated bars were $82/yd2 less than that of the stainless steel reinforcing over a 75-year design life

Epoxy-coated Reinforcing Steel in Repair of Concrete.

When repairing concrete that has deteriorated due to corrosion, it is important to ensure that the repair does not establish conditions that increase the rates of corrosion in surrounding concrete. This condition, frequently called the &#;ring anode&#; effect is described below.

When sufficient chloride reaches the level of the reinforcing steel in concrete, corrosion of the steel occurs. The location that has the highest corrosion rate is generally the location with optimum levels of chloride and moisture. At this anode location, the steel releases electrons that are then consumed at the cathode, which may be in areas of the structure that can be substantially further away from the damage.

During a typical concrete repair, it is common only to remove the damaged concrete, where the steel corrosion has resulted in an expansion that sufficiently damages the concrete. Unless precautions are taken as part of the repair process, corrosion damage in immediately surrounding areas may rapidly occur. This &#;ring anode&#; effect occurs as the area after the repair becomes the new anode, and the repaired area may become a strong cathode. At the cathode, electrons react with water and oxygen.

Due to the dielectric (non-conducting) coating on epoxy-coated bars, it is difficult for these bars to become cathodes. Thus, replacing exposed bars in the repair area with epoxy-coated bars substantially reduces the cathode and thus dramatically reduces the ring anode effect, leading to significantly enhanced repair life. Where bars are too short to be replaced or where areas of exposed uncoated reinforcing bars are present, it is recommended that they be coated with a repair material specifically designed to reduce the cathodic effect.
