What are the specific requirements for the performance of metal screens?
Publish Time: 2024-08-22
The performance requirements of metal screens usually include the following aspects:
Material quality:
Corrosion resistance: It should not be easy to rust or corrode in a humid environment or in the presence of certain chemicals. Screens made of stainless steel are corrosion-resistant in the atmosphere and suitable for a variety of environments; if used in high-salt environments such as the seaside, 316 stainless steel screens have stronger corrosion resistance.
Strength: It must have sufficient strength to withstand certain external impacts, heavy pressure, etc., to ensure that it will not be easily deformed or damaged during use. For example, in public places, it may be hit by people or squeezed by objects, and the metal screen should have the corresponding strength to resist.
Processing technology:
Welding technology: The welding point should be firm, the weld should be uniform and beautiful, and there should be no welding defects such as cracks and pores. High-quality metal screens have fine processing, smooth tangents, consistent angles, no obvious gaps during splicing, good sealing performance, and smooth switching; while inferior products may have problems such as rough welding points and cracks, and may even break or fall off under strong pressure and large external forces.
Surface treatment process:
Flatness: Whether it is a mirror effect or a brushed effect, the surface should be flat and smooth, without defects such as unevenness, waves or pits, otherwise it will affect the appearance. For example, a mirror stainless steel screen must be polished to form a mirror surface; a brushed stainless steel screen must be brushed and the brushed lines must be uniform, so that subsequent processing such as electroplating can be performed.
Color uniformity: If the screen has a color plating requirement, the color should be uniform and consistent, without color difference, color spots and other problems. For example, for common titanium plating and copper plating processes, the color difference must be controlled within a certain range (such as within 5%).
Adhesion: The coating or treatment layer on the surface should have good adhesion and should not peel off or fade easily. For example, the pattern or color formed on the metal surface by thermal transfer and other technologies should be able to withstand friction and wiping in daily use.
Appearance design:
Style diversity: A variety of different design styles can be provided, such as Chinese, European, modern and simple styles, to meet the aesthetic needs and decoration style matching of different customers.
Dimensional accuracy: The dimensions should be accurate, meet the design requirements, and match the spatial dimensions of the installation site. When installed, it can fit closely with the surrounding building structures or other decorative elements, and the gaps are uniform.
Hollowing or carving craftsmanship (if any): If the screen has a hollowing or carving design, the edges of the hollowing part should be neat and smooth, and the carving patterns should be clear and delicate, reflecting a good level of craftsmanship.
Stability:
Structural stability: The overall structure is stable, and there will be no unstable phenomena such as shaking or tilting after installation. For some large or high metal screens, special reinforcement measures or a reasonably designed support structure may be required.
Fire resistance: In some places with high fire protection requirements, metal screens should have certain fire resistance, be able to prevent the spread of fire within a certain period of time, and ensure the safety of personnel and property. For example, metal materials with fire resistance or special fire protection treatment are used.
Environmental protection: The material should meet environmental protection standards and contain no harmful substances, such as formaldehyde, heavy metals, etc. When used indoors, it will not cause harm to human health or pollution to the environment.
Easy to clean: The surface is easy to clean, not easy to be stained with dust, stains, etc., and the surface will not be damaged during the cleaning process. In daily use, it can be easily cleaned with ordinary cleaning tools and detergents to keep it beautiful and tidy.
Sound insulation performance (if required): If used in some places with high sound insulation requirements, such as conference rooms, offices, etc., metal screens should have a certain sound insulation effect, which can reduce the spread of sound and provide a relatively quiet environment.
