Housing construction projects are generally referred to as construction projects. They refer to the various technical work such as survey, planning, design, construction, installation and maintenance for the construction, reconstruction or expansion of housing buildings and ancillary structures, as well as the completed engineering entities. During construction, construction protection nets are often used. Construction guardrails and construction edge guardrails are site protection measures set up to ensure the safety of construction workers and to ensure safer construction. They are indispensable in the construction process. The current protection nets can only achieve some safety protection, personnel guidance, environmental protection and other functions, and rarely consider the protection of light. Therefore, there is a special need for a protection net that can prevent visible light and near-infrared detection.

[0003] Because most of the existing protective nets cannot block visible light during use, which means that outsiders can clearly see the indoor situation, which may expose the privacy of residents. For some places that require high privacy protection, such as residences and offices, this defect may bring safety hazards and cannot meet people's needs for privacy protection, energy saving and safety.
