Types of Shading Nets
- Round Wire Shading Nets
These shading nets are made from warp and weft threads that are cross-woven, typically using a warp knitting machine. When both the warp and weft are made of round wire, it is known as a round wire shading net.
- Flat Wire Shading Nets
In flat wire shading nets, both the warp and weft threads are woven with flat wires. These nets are lightweight, provide high shading rates, and are primarily used for agricultural and garden shading and sun protection.
- Round-Flat Wire Shading Nets
These shading nets are woven with either a combination of flat wire for the warp and round wire for the weft or vice versa. This creates a versatile shading net suitable for various applications.

How to Choose High-Quality Shading Nets
- Color
Common shading net colors include black, silver-gray, blue, yellow, and green. For vegetable cover cultivation, black and silver-gray nets are most frequently used. Black shading nets offer better shading and cooling effects than silver-gray ones, which are preferred for crops like green leafy vegetables (e.g., coriander and spinach) because they provide good light transmittance and help avoid aphids. Silver-gray nets are also beneficial for crops that need high light levels and are prone to viral diseases, such as radish, tomato, and pepper. For frost protection in winter and spring, both black and silver-gray nets are used, though silver-gray is often preferred.
- Shading Rate
The shading rate of a net can be adjusted during the weaving process, ranging from 25% to 75%, and can even reach up to 85% or 90%. For summer and autumn covering cultivation, a higher shading rate is desirable for crops like cabbage and other green leafy vegetables that are sensitive to high temperatures. Conversely, fruits and vegetables that require more light and tolerate high temperatures can use nets with lower shading rates. For winter and spring frost protection, nets with a higher shading rate are more effective. Generally, shading nets with a rate of 65% to 75% are used for most applications. The covering method and time should be adjusted based on the season and weather conditions to meet the growth needs of different crops.
- Width
Standard shading net widths range from 0.9 meters to 2.5 meters, with the widest being 4.3 meters. Some manufacturers offer customization based on specific needs. Commonly used widths are 1.6 meters and 2.2 meters. For covering cultivation, multiple nets are often spliced together to form a large, continuous cover. This makes it easier to manage, saves labor, and ensures the cover is secure against strong winds. When selecting a shading net, consider the size of the coverage area and choose the appropriate width for splicing. Cut the net with a soldering iron to seal the edges, and use nylon thread instead of cotton for splicing to ensure durability and firmness.
