Why does stainless steel mosquito net deform shortly after use

Stainless steel mosquito nets deform shortly after use, mainly due to material thickness, processing technology, installation method, and external impact. The following is a specific analysis:

1、 Material and thickness: Thin stainless steel NetEase deformation

Thin plate curling problem

If the stainless steel mesh material is thin (such as wire diameter ≤ 0.5mm), it is prone to curling due to stress release during stretching or cutting. For example, some mosquito nets with suitable prices use thin stainless steel plates to reduce costs, which have insufficient rigidity and are prone to sagging and deformation due to long-term effects of gravity or wind pressure.

The wire diameter does not match the mesh size

Thin wire diameter: For example, a 20 mesh stainless steel mesh with a wire diameter of 0.2mm has good transparency, but weak impact resistance. Slight external forces (such as child tapping) can cause deformation of the mesh.

Excessive mesh size: High mesh sizes (such as 200 mesh) have fine mesh sizes, but require finer wire diameter weaving, resulting in reduced overall strength and easy deformation due to local stress concentration.

2、 Processing process defects: insufficient leveling and welding issues

Lack of leveling process

After the production of stainless steel mesh, internal stress needs to be eliminated through a leveling machine, otherwise it is prone to natural curling. Some small factories skip this step to save costs, resulting in gradual deformation of the mesh after installation.

Insufficient welding point strength

If the welding between the mesh and the frame is not firm, the welding points will fall off after long-term use, and the mesh will lose support and collapse.

Example: If the hardware components (such as hinges and locks) of the diamond mesh window are not installed properly, they will cause pulling and pulling on the mesh during opening and closing, resulting in local deformation.

3、 Improper installation method: poor compatibility between frame and mesh

Insufficient framework strength

The use of inferior aluminum or plastic frames cannot withstand the tension of the mesh, and after long-term use, the frame deforms, causing the mesh to twist.

Comparison: Excellent diamond mesh window frames often use thickened aluminum alloy (wall thickness ≥ 1.2mm), which has strong deformation resistance.

Sealing design defects

If there is no sealing strip installed between the screen window and the window frame, or if the strip ages and falls off, the edge of the mesh is easily deformed by wind pressure compression.

Example: In coastal areas, due to strong winds, if the sealing of the screen window is poor, the mesh may be blown out of the groove, causing long-term deformation.

4、 External impact: usage scenarios and lack of protection

sabotage

When children play, hitting with hard objects or scratching with pets may cause the mesh to sink or tear.

Case: A user reported that their pet dog frequently scratched the screen window, causing local wire diameter breakage and holes in the mesh.

environmental factor

Wind pressure: High rise buildings or wind outlet locations may experience fatigue deformation of the mesh due to sustained strong winds.

Temperature difference: Under extreme temperatures (such as winter in the north), stainless steel undergoes thermal expansion and contraction. If the mesh is fixed too tightly to the frame, it may deform due to stress concentration.

5、 Misconception in Material Selection: Stainless Steel ≠ Further Understanding of Deformation

The influence of material type

201 stainless steel: high manganese content, poor corrosion resistance (based on actual reports), easy to rust and become brittle. Slight external force can cause deformation.

304/316 stainless steel: high nickel content, strong corrosion resistance (based on actual reports) and toughness, less prone to deformation, but at a higher cost.

Surface treatment differences

Stainless steel mesh without anti rust coating is prone to rusting in humid environments, which weakens the material strength and accelerates deformation.

Comparison: Stainless steel mesh treated with electrophoretic paint or PVC coating has improved rust prevention performance and extended service life.

6、 Solutions and preventive measures

Choose high-quality materials

Priority should be given to using 304 or 316 stainless steel mesh with a wire diameter of ≥ 0.8mm and a mesh size between 11-20 (taking into account both mosquito resistance and strength).

Example: It is recommended to use 0.7mm wire diameter and 11 mesh stainless steel mesh for the diamond mesh window, which has strong impact resistance and excellent mosquito prevention effect.

Optimize installation process

Confirm that the frame matches the mesh size, and reserve appropriate tension during installation to avoid being too tight or too loose.

Using a thickened aluminum alloy frame and equipped with sealing wool strips to enhance wind pressure resistance.

Strengthen daily maintenance

Regularly check if the screen window hardware components (such as hinges and locks) are loose and tighten them in a timely manner.

Avoid hitting or scratching the mesh with hard objects. Pet households can install protective fences.

Alternative solution: High transparency mesh window screen

If high ventilation and lighting requirements are needed, PET high transparency mesh (such as strip wheel resin mesh) can be chosen, which is dust-free, highly transparent, and has better aging performance than stainless steel mesh.
