The appearance of this product has been pickled and phosphated, electrostatic sprayed, corrosion-proof and rust-proof, strong and reliable. The column is welded by two horizontal braces and three diagonal braces (customizable), which increases the gravity of the column. Strong welding technology, every welding point is welded firmly to ensure stability and pay attention to details. Welding the ground sheet enhances the friction of the ground and fixes the shelf on the ground, making it more stable and secure. The maximum load is 3000kg. 1. The shelf is a kind of shelf structure, which can make full use of the warehouse space, improve the utilization rate of the storage capacity, and expand the storage capacity of the warehouse; 2. The goods stored in the shelf are not squeezed by each other, and the material loss is small, which can completely guarantee the physical assets. The function of the product can reduce the loss of the goods; 3. The goods in the shelf are easy to access, easy to count and measure, and can be first in, first out; 4. To ensure the quality of the stored goods, it can be moisture-proof, dust-proof, anti-theft, and anti-vandal Measures such as to improve the quality of material storage; 5. The structure and function of many new shelves of cold storage shelves are conducive to the realization of mechanization and automatic management of the warehouse. The cold storage shelf industry has undergone many periods of development. According to the different temperatures of the stored goods and the different storage methods, my country has now formed the main types of cold storage shelves such as ultra-low temperature storage, freezer storage, cold storage, and fruit and vegetable air conditioning storage. Ultra-low temperature warehouse shelves are mainly used to store goods whose temperature needs to be lower than -20°C, such as frozen fish, frozen meat, frozen seafood, frozen prepared foods and ice cream. Ensure that the speed of qualitative change of the goods under ultra-low temperature conditions is minimal, and the shelf life is increased. Freezer shelves are mainly used to store goods whose temperature is between -2°C and 20°C, such as frozen poultry meat, frozen livestock meat, smoked products, butter, etc. Ensure that the goods can maintain the best freshness, nutrition and eating quality within this temperature range. The cold storage is mainly used to store goods whose temperature is between 2℃ and 10℃, such as: fresh fish, dairy products, wine, butter, eggs, ham, etc. Keep the goods in this temperature range with the best taste and nutritional value.
