One、Whether wall covering corners need to be covered with metal strips
Whether to cover the corners of wall fabrics with metal strips is a matter of personal preference. Whether or not to cover the corners is up to you. If you choose to cover the corners of your wall fabric with metal strips, be sure to select metal strips that complement the fabric's color. There are several options for metal strips to cover the corners of your wall fabric:

1、Aluminum alloy profiles. These aluminum alloy profiles are made from pure aluminum, along with other alloy elements, and are formed through extrusion. They are characterized by their lightweight, high strength, corrosion resistance, abrasion resistance, and a very prominent, light-reflecting surface, making them suitable for decorating ceilings or framing mirrors.
2、Copper alloy strips. This copper alloy is made of brass, which has high strength and is also resistant to corrosion. After processing, it can exhibit a beautiful golden color. It is typically used for metal inlaying in flooring made of marble or granite, as well as for decorating stair treads and high-end furniture.
3. Stainless steel strips: These strips are relatively more affordable and offer good durability, resistance to abrasion, and a mirror-like finish, resulting in excellent decorative effects.
Two. How to apply metal strips on wall coverings.
1、Embedding Method
One method is the embedding method: First, create a groove on the wall surface by chiseling. The dimensions of the groove should be based on the specifications of the metal strip, and the depth should also be consistent. In normal conditions, the groove depth will be deeper than the actual specifications. Then, apply the stone adhesive to the groove and embed the metal strip inside, ensuring that the position and dimensions are correct. After the adhesive has not fully dried, use a utility knife to remove any excess adhesive. Finally, allow it to dry completely.
2、Floating application method
Another method is the "floating" technique, where the cloud stone adhesive is applied to the underside of the metal strip, then applied to the surface of the fabric. The area around the strip must be properly prepared and smoothed before application. After a few minutes, any excess adhesive is removed before the adhesive is completely dry. Finally, after it is fully cured, the surface can be finished.
Third, should the wallpaper be applied first or the metal strips be installed first?
"In many cases, metal strips are installed first. After the metal strips are installed, they need to be ground and patched. Additionally, if the metal strips are not installed properly, the painters may need to fill in the gaps to achieve the desired finish."
