Raw material selection and preparation

Raw material selection: The main raw material of scaffolding mesh is plastic particles, especially high-density polyethylene (HDPE). In addition, recycled materials such as mineral water bottle caps can also be used after machine crushing and granulation.

2. Wire drawing or filament making

Wire drawing process: The selected raw materials are drawn or filamented by machine. In this process, the temperature of cooling water needs to be precisely controlled to ensure that the output plastic wire has the appropriate thickness, color and flexibility. These characteristics will directly affect the quality and performance of the final product.

3. Weaving process

Weaving process: Plastic wire is woven into a mesh structure using a special mesh loom. The weaving structure and density of the mesh need to be controlled during the weaving process to ensure that the finished product meets the requirements of use. Commonly used mesh looms have a variety of specifications such as 2 meters and 4 meters wide.

Quality control: The weaving process is crucial to the quality of the finished product, and it is mainly necessary to control the mesh density and the uniformity of the weaving structure. Generally, the mesh density should meet or exceed the standard of 800 mesh/100cm².

4. Cutting and sewing

Cutting: Cut the woven cylindrical mesh into appropriate lengths, generally measuring 6.2 meters to 6.5 meters, to ensure that the finished product length remains at about 6 meters after sewing.

Sewing: Use a sewing machine to wrap the rope around the edge of the mesh and tighten it to sew. The weight of the rope should match the mesh and should not be too light or too heavy. At the same time, it is necessary to ensure that the stitching is firm, and usually the edge of the mesh is sewn twice to increase the firmness.

Application scenarios

The application scenarios of second-hand scaffolding nets are similar to those of new scaffolding nets, mainly including but not limited to the following aspects:

Construction industry: In construction, scaffolding nets are widely used to build temporary support structures to ensure the safety of construction workers.
Bridge and tunnel construction: Scaffolding nets also play an important role in the construction of transportation facilities such as bridges and tunnels.
Power and communication industry: Scaffolding nets are also an indispensable auxiliary tool in the construction and maintenance of power lines and communication towers.
Other industrial fields: Scaffolding nets are also widely used in industrial fields that require temporary working platforms, such as shipbuilding and chemical industry.

In short, second-hand scaffolding nets play an important role in construction and other related fields with their cost advantages, environmental protection concepts and stable performance.
