The use of refrigerated trucks to transport different items should be consistent with the temperature adjustments in the insulated cars, or else it will cause deterioration and damage to the items. When refrigerating trucks transport fruit and vegetable products, how do they adjust to the right temperature? 1. Most of the transport temperature in the frigid and temperate leaves and rhizomes is preferably between zero and two degrees Celsius, and it is better not to be lower than zero. And we usually eat fruits and vegetables such as. spinach. Fresh fruits and vegetables such as grapes, celery, Chinese cabbage and so on, do not rush to store in the cold storage just after picking it back, because in the low temperature environment, the enzyme activities in the fruits and vegetables are prefabricated, so there is no way Decompose the residue that remains on the fruits and vegetables. So, after putting the fruits and vegetables in the greenhouse for 24 hours, it is the best choice to put into the cold room. 2, some fruits and vegetables in the moisture content is more, if it is a long time after the refrigerated there will be taste, deterioration of the situation, so it is best to store at about ten degrees Celsius temperature. For example: fruits and vegetables such as pumpkins, cucumbers, wax gourds, tomatoes, etc. 3, tropical fruit because it is the reason for the growth of the environment, so it is best to be placed in some relatively cool or can avoid the sun's direct place to save. If it is necessary to use a refrigerated truck for transport, then the best transportation temperature is in the range of 7-10 degrees Celsius, and when transporting, the time must be the best is not to exceed 48 hours. 4. When using a refrigerated truck to transport fresh milk, the temperature is preferably around 2-4 degrees Celsius. When transporting frozen fish, it is best to adjust the temperature of the insulated compartment to a temperature below minus 3 degrees Celsius. In such a temperature environment, the frozen fish will not be degraded and the umami taste can be maintained.
Galvanized Steel Sheet & Plates, are intended for use where greater corrosion protection is required without painting. A lower cost alternative to stainless steel, galvanized sheet and plates have a rust free protection for up to 30 years, while maintaining strength with a durable surface coating. Our company stocks many sizes in precut sizes, full mill sizes or we can hot dip virtually any size and quantity required for your welding or construction project.
Galvanized steel Sheet coil has a light weight, beautiful and good anti-corrosion performance, can be directly processed. Is mainly used in construction, shipbuilding, automobile manufacturing, machinery manufacturing, furniture home appliance industry, electrical and automation industry. Efficient construction, save energy and protectenvironment, prevent pollution etc.

Hot-dip galvanized sheet is made by immersing the steel sheet in a molten zinc bath at about 500 °C to attach a zinc layer to the surface. This is the continuous galvanizing process. It will form a protective zinc layer on the surface so that it has good paint adhesion and weldability. It is the most widely used and cost-effective method to prolong the service life of steel sheets.
Electro-galvanized Steel Sheet
Electro-galvanizing, also known as cold galvanizing, uses electrolysis to form a uniform and dense layer on the surface of the metal. The anti-corrosion zinc layer can protect steel parts from oxidation corrosion. Also, it can meet decorative purposes. But the zinc layer of the electro-galvanizing steel sheet is only 5-30 g/m2. So its corrosion resistance is not as good as hot-dip galvanized sheets.
