Colored steel is suitable for various projects outside the cold storage industry, such as knockdown house (pre-fabricated house) walls, shop walls, or cafe walls, to create dimension and aesthetic appeal. It comes in various colors, reduces construction time, allows for quick installation, and offers more design options compared to traditional masonry construction.

White-coated food-grade steel is ideal for building cold rooms, clean rooms, and processing rooms. These areas need to be kept strictly clean and maintained in food-grade environments. Therefore, a special type of steel is necessary to prevent various pathogens that could damage products. Another type of steel, known as ‘CRP’ (Cold Room Panel), is also certified to global standards. It features a coating with special substances that effectively prevent bacterial growth and is registered with agencies in the United States and the European Union. This ensures that steel with such coating is safe and does not adversely affect food raw materials or users’ health, as it prevents pathogen contamination in the area that could otherwise be harmful.

Additionally, the white-coated steel allows consumers to assess the steel’s quality throughout its use, as the average lifespan is 15 to 20 years depending on maintenance and proper usage, with proper usage translating to a longer lifespan.

This longevity explains why it’s globally accepted and used in many major industries.
