FAQs About This Product

Can Mild Steel Perforated Mesh be Used to Reinforce Cement?

Mild steel perforated mesh can be used in conjunction with cement in some applications, but it’s not typically the primary choice for structural reinforcement. When considering reinforcing cement, the primary objective is to provide tensile strength to the cement structure. Cement, by its nature, has high compressive strength but lacks in tensile strength. Traditional reinforcement methods involve using rebar or wire mesh, both of which provide continuous steel structures that offer tensile strength and bonding with the cement.

Mild steel perforated mesh has the following considerations:

1. Coverage: The perforations in the mesh mean that there are voids without steel, potentially resulting in less uniform tensile strength across the structure.

2. Corrosion: Mild steel is susceptible to corrosion, especially when in contact with moisture. Over time, the steel can corrode within the cement, potentially causing structural issues and even leading to the cement cracking as the steel expands from rust.

3. Bonding: The surface area available for bonding with the cement might be less than with traditional reinforcing materials due to the perforations. However, the edges of the perforations can offer some mechanical bonding with the cement.

4. Applications: While not ideal for primary structural reinforcement, mild steel perforated mesh could be used in niche applications where the objective isn’t primarily about structural integrity. For example, it might be suitable for creating decorative cement panels, where the mesh provides a modicum of reinforcement while allowing for aesthetic designs.

5. Protection: If used within cement, it’s advisable to coat or treat the mild steel to enhance its resistance to corrosion.

How do you Calculate the Open Area of Perforated Mesh?

Calculating the open area of a perforated mesh helps determine the percentage of space that allows for passage of light, air, sound, etc., as compared to the total area of the mesh. Here’s how you can calculate the open area:

1. Determine Hole Geometry: First, identify the shape of the perforation. Common shapes include round, square, and hexagonal. For this example, let’s consider round holes.

2. Calculate Area of One Hole:

   • For round holes, the formula to calculate the area (A_hole) is: Ahole​=πr2 where $r$ is the radius of the hole.

   • For square holes: Ahole​=a2 where $a$ is the side length of the square.

3. Determine the Number of Holes per Unit Area: Count the number of complete holes in a specific unit area (e.g., per square inch or square centimeter). Let’s call this number $N$.

4. Calculate Total Open Area in the Unit Area: Multiply the area of one hole by the number of holes: Aopen​=Ahole​×N

5. Calculate Open Area Percentage: Open Area Percentage=(Aopen​​/Total Unit Area)×100%

For example, if you have round holes with a diameter of 2mm in a 1 square centimeter area, and there are 10 holes in that area:

1. Radius $r$ = 1mm
2. Area of one hole Ahole​ = π(12) = 3.14 mm^2
3. Total open area in 1 cm^2 Aopen​ = 3.14 mm^2 x 10 = 31.4 mm^2
4. Open Area Percentage = (31.4 mm^2 / 100 mm^2) x 100% = 31.4%

Can I use Plain Steel Perforated Sheet for Outdoor Purposes?

Yes, you can use plain steel perforated sheets for outdoor purposes, but there are essential considerations to keep in mind:

Plain steel, when exposed to the elements, is susceptible to rust and corrosion. The moisture in the air, especially in humid or coastal areas, can quickly lead to the formation of rust on the steel’s surface. If you’re using plain steel perforated sheets outdoors, you’ll need to take preventive measures to protect the steel from corroding.

One common method to safeguard the steel is by applying protective coatings. Galvanising, which involves coating the steel with a layer of zinc, is a popular method to provide corrosion resistance. Additionally, painting or powder coating can further protect the steel while also offering an aesthetic finish. Regular maintenance, like cleaning and checking for signs of wear or corrosion, can help extend the lifespan of the sheet.

Furthermore, consider the specific outdoor application. For instance, if the sheet will be in contact with the ground or plants, it might be exposed to additional moisture and could corrode faster.
