What is a RAL color card?
Since RAL became involved with color in 1927, it has created a unified language, establishing standard statistics and nomenclature for various colors, and these standards are widely understood and used around the world. 4-bit RAL colors have been used as color standards for 70 years and have developed to more than 200 types so far. The basic color card for matte colors is RAL-840HR, and the basic color card for glossy colors is 841-GL. These basic color blocks meet a wide range of applications and are used by many important companies and research institutions. The RAL-840HR and RAL-841GL color registries serve as color samples for use in designs and they also include safety and signal colors that comply with DIN and ISO specified color requirements.
Color-coated steel coil is a steel coil made of cold-rolled steel plate or galvanized plate as the base material, surface pretreatment, coating with one or more layers of organic coatings, and then baking and solidification. It has many advantages such as rich colors, strong weather resistance, good decorative properties, and good anti-corrosion properties. It has been widely used in construction, home appliances, transportation, furniture and other industries.
Advantage:
1. Rich colors
Color-coated steel coils can be made into a variety of colors according to customer requirements, making their application range wider and able to meet the decoration needs of different occasions.
2. Strong weather resistance
Because the surface of the color-coated steel coil is coated with a strong weather-resistant layer, it has good corrosion resistance and oxidation resistance, and can maintain long-term stable appearance and performance when used in various harsh climate conditions.
3. Good decoration
Color-coated steel coils have high surface flatness and bright colors, which can provide good anti-corrosion functions and meet aesthetic requirements, making them suitable for various buildings and home decorations.
