The purpose of welded wires in PVC flooring rolls is to facilitate the heat welding process during installation. PVC flooring is often installed using a method called heat welding or hot air welding, where adjoining pieces of flooring are bonded together using heat to create a strong and seamless seam.

Here's how the welded wires are used in the installation process:

Creating Grooves: Before laying down the PVC flooring, grooves or trenches are typically cut into the flooring material using a trencher tool. These grooves are where the welded wires will be inserted.

Inserting Welded Wires: Once the grooves are cut, welded wires, which are typically made of the same PVC material as the flooring, are inserted into the grooves. These wires are designed to fit snugly into the grooves, creating a flush surface with the flooring material.

Heat Welding: During the heat welding process, a heat source such as a welding torch or hot air gun is used to heat the PVC material along the seams where the welded wires are inserted. As the PVC material softens, the welded wires melt into the flooring, creating a strong bond between the adjoining pieces.

Seam Reinforcement: The welded wires reinforce the seams of the PVC flooring, making them more resistant to wear and tear and providing additional structural integrity to the installation. This helps to prevent the seams from separating over time, especially in high-traffic areas.

Seam Appearance: In addition to providing structural support, heat-welded seams with welded wires also create a seamless and aesthetically pleasing finish. The welded wires help to ensure that the seams blend seamlessly with the rest of the flooring, creating a uniform and professional-looking installation.

Overall, the use of welded wires in PVC flooring rolls plays a crucial role in ensuring a durable, long-lasting, and visually appealing installation. It helps to create strong seams that are resistant to damage and maintain the integrity of the flooring over time.
