Metal corner guard is a building material widely used in construction, mainly used to protect corners and improve the overall beauty and durability of buildings. The following is a detailed introduction to metal corner guard:

1. Product features
Excellent material: Metal corner guard is usually made of high-quality galvanized material, which is anti-aging, corrosion-resistant and fire-resistant, and effectively prevents rust. This material ensures the long-term stability of the corner guard in harsh environments.
Precise design: The metal corner guard has a precise sharp angle size design, which can avoid concentrated force when the corner is hit, and evenly disperse the external force to the edge parts around, thereby effectively protecting the intactness of the positive corner.
Convenient construction: The metal corner guard is divided into two types: punching and expansion. It is not only convenient for nailing, but also makes the corner guard more firmly combined with the gypsum board or other bonding materials in the corners. In addition, its construction does not need to rely on wooden strips, and primary plasterers can easily complete the construction of straight lines in the corners, thereby shortening the construction time and reducing the construction cost.
Strong anti-collision ability: Metal corner guards can effectively prevent construction workers from hitting the corners and causing damage during construction. At the same time, they also enhance the anti-collision ability of the corners of the building after completion, reducing the maintenance costs caused by damage to the corners.
Solve quality problems: Metal corner guards can solve the long-standing quality problems of corners that are not straight, uneven, unsightly, and easy to damage in construction, ensure that the insulation mortar layer is free of cracks, and improve the quality of the project.
2. Scope of application
Metal corner guards are widely used in various construction projects, including internal and external insulation systems, indoor and outdoor decoration, etc. In the insulation system, it can effectively prevent the corners from cracking and improve the insulation effect; in indoor and outdoor decoration, it can maintain the straightness and beauty of the corners and reduce the later maintenance work.

3. Construction process
The construction process of metal corner guards usually includes the following steps:

Preparation: Clean the surface of the corners to ensure that there is no dust, oil or other impurities.
Fix the corner guard: Use nails or special adhesives to fix the metal corner guard on the corners, and pay attention to keeping the corner guard straight and firm.
Plastering and leveling: After fixing the corner guard, plastering and leveling work is carried out to make the surface of the corner more flat and beautiful.
Subsequent treatment: Carry out subsequent decoration or protection treatment as needed, such as painting, wallpapering, etc.
4. Precautions
When purchasing metal corner guards, you should pay attention to choosing products with reliable quality and excellent materials to ensure construction quality and service life.
During the construction process, the construction specifications should be strictly followed to avoid safety hazards and construction quality problems.
Regularly inspect and maintain the metal corner guards to detect and deal with potential problems in a timely manner to extend their service life and maintain the beauty of the corners.
