Mesh Count (the number of openings per inch)
What it really means is how clear or fine the filter is.
Not high enough? Small animals or trash can get in. Is it too tall? Something is blocking the flow of air or light.
We recommend:
Choose a 4–10 mesh if you want to keep mice and other pests out. This keeps people out while letting air flow.
Choose a mesh size between 40 and 100+ for fine filtering or sieving. This catches very small particles for precise industrial processes.
The size of the wire, or the wire gauge
What it really means is that it is tough, strong, and will last a long time.
Is it too thin? When you put weight on it, the mesh bends, sags, or breaks. Too thick? More trouble, weight, and cost to put it together.
We recommend:
Choose a thick wire (6–9 gauge) for security fencing that will last a long time. It can take cuts and hits for more than ten years.
If you want a garden fence that isn't too heavy, pick a medium wire (12–16 gauge). The item protects well without being too strong.
Material and coating
What it really means is to keep rust from ruining your environment.
Did you pick the wrong thing? Rust weakens the structure, which makes it fail sooner and costs more to replace.
We recommend:
For regular outdoor fencing, such as on farms and backyards, you should use hot-dip galvanized steel.
Use stainless steel (304 or 316) in coastal, industrial, or other harsh, wet, or chemical environments. For important, long-term uses, it is the most resistant to rust.

Our Core Promise: Why Precision Matters More Than Product
For us, a wire mesh is not a commodity; it's a critical component in a system where failure has tangible costs—downtime, safety incidents, and project overruns. Our core value lies in translating your unspoken engineering requirements into material certainty. We don't just sell mesh; we provide calculated risk mitigation.
Customization Beyond Size: It's all about fixing the way your product fails. We are not just meeting a general requirement, but also helping you lower your total cost of ownership and achieve long-term structural integrity by changing length, coating, or tensile strength of a mesh.
Precision for Productivity: Consistent gauge and weave aren't just ways to check quality; they are also necessary for quick installation and reliable performance. This keeps your crews on track with important project deadlines by making sure they work faster without having to do the same thing over again.
We help you avoid catastrophic failures caused by corrosion by ensuring mesh integrity in critical environments through the use of appropriate raw materials (such as 316 stainless steel for high-chloride environments). It's not just about selling products—we ensure mesh works reliably for decades without any maintenance.
Our Origin: A Foundational Belief
Engineers who were sick of the gap between supply and application started Sinsun. Off-the-shelf mesh doesn't hold up to real-world stress, leading to project delays and budget overruns.. It would corrode too soon in a coastal fence or bend in a concrete slab. This frustration led to our unique philosophy: every mesh must be designed to be fit for its purpose. We work directly with you as your engineering partner from the start, asking "What problem are you really solving?" before we give you a price.
The Sinsun Difference: Clarity Over Claims
Manufacturers and advisors don't work in isolation like distributors who sell from a catalog. There are three main differences:
1. Rather than providing inventory availability alone, we provide specific specifications based on data (ex. percentage of airflow open area or width of a strand for load-bearing grating
2. Predictable Reliability: Because we have strict process control, you can be sure that the mesh sample you approve is the same mesh you get in bulk every time. This stops expensive surprises and quality rejections that happen on site.
3. Working together to solve problems: We look at the reasons behind your project. It's not enough to just put up a fence around a chicken coop; you also have to think about managing operational risk and liability. Metal reinforcement in concrete is not just about ensuring the structure lasts for a long time; it also requires ensuring that the construction doesn't have to stop. We offer the answer that was made for that deeper reality.
In short, we connect the dots between what is said in theory and what happens in the real world. When you buy Sinsun, you're not getting a product; you're getting a verified part for a system that can't afford to break down.
Q: Is galvanized chicken wire strong enough to keep rabbits out of a vegetable garden?
+
A: Standard galvanized hex netting works for short-term use (1–2 years). If you want a permanent solution, ask for a PVC-coated one. Rabbits can chew, but a 1" (25mm) hexagonal hole keeps them from getting through. The PVC layer keeps the zinc coating from breaking down because of soil acids, which makes it last for more than five years.
Q: What are the benefits of using welded wire instead of woven mesh to protect machinery?
+
A: The size of the openings in welded mesh is fixed, and the mesh is very strong. Due to the welded joints, the mesh does not bend or change shape at stress points, which keeps the aperture dimension constant (for example, ANSI B15.1 ). Woven mesh is less stable than welded mesh because of its bending and shape changes.
Q: Can standard poultry netting be used for tree protection?
+
A: Yes, but it must be thicker (19 gauge or more) and preferably PVC-coated green. This resists weathering and prevents the wire from cutting into growing bark. Because of its hexagonal weave, it can be formed around trunks without damaging the cambium layer.
Q: What makes you choose between fixed panel and continuous roll fencing?
+
A: Speed of installation vs. ability to adapt to different types of terrain. Pre-fabricated wire fence panels (for example, 2.4m x 1.2m) can be set up quickly on flat ground with pre-set post spacing. Because wire fencing rolls can follow the shape of the land, they are better for uneven ground, but they must be unrolled and tensioned on-site.
Q: How do I order a galvanized chain link fence that will last for 15 years in an industrial area?
+
A: Name three things: 1) Fabric: A Class III coating of hot-dip galvanized steel with at least 245 g/m² of zinc. 2) Structure: Schedule 40 pipe that has been hot-dip galvanized after it was made. 3) Fittings: All nuts, bolts, and tension bands must be hot-dip galvanized. This makes sure that cathodic protection is complete.
Q: How do we stop a 50m roll of field fence from twisting and kinking when we unroll it?
+
A: Lay the roll flat on its side and roll it along the fence line. Don't turn it over and over. Use a come-along or a special tool to pull on the fence so that the tension is the same from the center to the ends, not just from one end. This keeps the shape and tension of the mesh.
Q: Why is a twisted (ribbed) wire used in concrete mesh (fabric)?
+
A: The ribs (deformations) make the bond between the steel and the concrete much stronger, by as much as 40% compared to smooth wire. With this mesh, slippage is prevented when there is a load, which means shrinkage cracks are controlled and localized stresses are spread out evenly.
Q: Can chain link be protected against rust with vinyl coating?
+
A: Its main job is to protect against scratches and keep its color, not to protect against bulk corrosion. The zinc galvanizing underneath is the layer that gives up its life. The vinyl sleeve (which is usually 0.3 to 0.5 mm thick) protects the zinc from damage from tools and UV rays, which makes the zinc last longer, especially in areas with a lot of foot traffic.
Q: Can you use PVC-coated mesh as a temporary safety barrier on a construction site?
+
A: You can use it to mark pedestrian areas or prevent debris from spreading, but not to protect against falls. One good thing about it is that it is easy to see (in orange or green). When you use it seasonally, make sure the steel core wire is at least 2.0mm in diameter, and check that the PVC does not get brittle.
Q: What are the most important features of a ventilation mesh for an electrical cabinet?
+
A: Make sure there is good airflow and EMI/RFI shielding. A perforated sheet or woven mesh with about 40% open area will be useful for cooling things down. For shielding, use a sheet with very small holes (less than 2mm) or a copper/steel woven mesh with a high mesh count (like 100 per inch). Make sure it is securely connected to the cabinet frame.
Q: Does putting a black vinyl coating on a fence make it hotter and hurt it?
+
A: Yes, black surfaces do take in more solar thermal energy. It can cause the steel to expand and contract more quickly, resulting in faster wear out of the coating. This effect is taken care of within the product's design life, though, for a high-quality black wire mesh fence with a stable polymer formulation (like LLDPE). It's worth it for the looks and privacy it gives.
Q: We need a guard panel that lets air through but has metal shavings in it. What is the best pattern for holes?
+
A: Use round holes with a diameter of no more than 3mm and a center-to-center pitch of 4–5mm. This gives about 40–45% open space for air to flow through while keeping most machining swarf from getting through. perforated metal shee that is 1.5 mm thick is the right amount of stiff.
Q: When do you need Type 316 stainless steel wire mesh instead of Type 304?
+
A: In places where chlorides are found, such as coastal areas, chemical processing, or where de-icing salts are used. Type 316 has 2 to 3% molybdenum, which makes it less likely to get pitting and crevice corrosion. 304 is fine for indoor, dry, or mild conditions, and it's also less expensive.
Q: How can a wire netting fence stay up on a farm?
+
A: It depends on how much zinc is on the wire. The best coating for agricultural use is hot-dip galvanized 60–80 g/m2 (Zinc Class 1 or 2). Electroplated coatings that are lighter (10–20 g/m²) will break down quickly, which will cause rust and make the container weaker.
Q: What mesh specifications in a food processing plant keep bacteria from growing?
+
A: Ask for a stainless steel welded wire mesh with a smooth, polished finish. There can't be any cracks in the joints, and they have to be completely welded and ground smooth. Make sure that your aperture is both strong and cleanable. It is often the best choice to use a 1" x 1" (25mm x 25mm) aperture with a 2mm wire diameter, since it lets in light, allows air to flow, and is easy to clean.
Q: How tall should a two-strand barbed wire fence be so that animals can't get through?
+
A: First, 48 to 52 inches (120 to 130 cm) of string should be installed above the ground, and then 24 to 28 inches (60 to 70 cm). Because cows and horses see things this way, it's a visible barrier that they are less likely to try to get through. This takes some of the stress off the fence.
Q: How can a portable electric netting fence be repaired if the voltage is lost?
+
A: Mitigation means: 1) Making sure that the grass along the fence doesn't get too tall. 2) Using an energizer that has at least 0.5 joules for the length of the fence. 3) Putting in separate ground rods for the energizer in dry soil to make sure the circuit is complete.
Q:What aperture is really mouse-proof?
+
A: No more than 6mm (1/4 inch). Mice can squeeze their skulls to fit through holes that are a little bit bigger than this. So, the engineering standard for exclusion in food storage or building utility penetrations is a welded mouse mesh with a 6x6mm opening made of at least 19-gauge (1.0mm) wire.
Q: What kind of material and weave is best for screening insects on industrial vents?
+
A: Use a plain (square) weave aluminum fine wire mesh with holes that are 1.2mm x 1.2mm. Aluminum doesn't rust and doesn't have a magnetic field. This size of opening keeps most flying bugs out while letting air flow through with little pressure drop. A wire with a diameter of 0.25 to 0.28 mm is strong enough.
Q: Why do gabion baskets use double-twisted hexagonal mesh instead of welded mesh?
+
A: The double-twisted structure lets the mesh change shape without breaking apart when it settles or when there is lateral earth pressure. If the wire breaks, the twist holds it in place.The failure of one joint of a welded mesh can lead to the basket becoming less stable and stones falling out. This is a common way for retaining structures to fail.
Q: What is the most important safety standard for the strength of the mesh in a removable mesh pool fence?
+
A: It has to be able to hold a horizontal load without making a hole that people can climb through. The mesh's burst strength (more than 50 psi) and the strength of its border webbing are both very important.Posts and latches should also be certified to a standard such as ASTM F2286, which simulates the weight and force of children.
Q: How do we keep mice out of a compost bin? Is galvanised mouse wire enough, or do we need stainless steel?
+
A: Galvanised mesh is enough. Compost's organic acids are not as corrosive as chemicals used in industry. The most important things are the aperture (≤6mm) and the wire gauge (≥19ga). Make sure that all seams overlap by at least 50mm and are securely fastened (for example, with hog rings or galvanised staples) so that mice can't get in through the joints.
