Construction site has not completed the building, why should cover a piece of green "cloth"?

The safety net is generally installed on the outside of the scaffold. If a construction worker falls while working, he or she can hold the safety net to stop the fall. Even if he or she does not hold it, the safety net can also play a role in slowing down and reducing the damage to the human body caused by accidental fall. The safety net also intercepts falling materials or tools from buildings, preventing them from injuring workers or passers-by.

In addition to reducing fall injuries, safety nets have several other functions. Construction sites produce a lot of dust and noise, and safety nets can reduce their pollution to the environment to some extent. Safety net materials generally have flame retardant, can prevent welding sparks caused by fire. In addition, when construction workers are working at height, the safety net can block the lateral wind and block the workers' view down, reducing the fear of height.

In order to play an effective protective role, safety net materials need to have a small proportion, fracture resistance, impact resistance, aging resistance and other physical properties. At present, high density polyethylene (HDPE) is the main manufacturing material for safety nets in construction sites. The weight of each safety net is generally no more than 15kg, and the breaking strength of the rope is more than 3000N.

Therefore, the next time you encounter a building on the construction site or the land "wearing" a piece of green clothes, do not think it is a piece of cloth, it is actually a protective net, not only to protect the safety of workers and pedestrians, but also to maintain the clean and tidy urban environment.
