Alloy steel plate
Alloy steel plate
Steel plates are flat, rectangular, and can be directly rolled or cut from wide steel strips.
Steel plates are divided by thickness, thin steel plates are <4 mm (the thinnest is 0.2 mm), thick steel plates are 4 to 60 mm, and extra thick steel plates are 60 to 115 mm.
Galvanized steel plate
Galvanized steel plate is a material that improves its corrosion resistance by coating a layer of zinc on the surface of the steel plate. This coating helps to prevent the steel plate from reacting with oxygen, water, and other chemicals in the environment, thereby slowing down the process of steel corrosion. Here are some basic introductions about galvanized steel plates:
1. Galvanizing process: Galvanizing is achieved by coating a layer of zinc on the surface of the steel plate. The two most common galvanizing methods are hot-dip galvanizing and electrogalvanizing. Hot dip galvanizing

Galvanized sheet steel
Galvanized sheet steel products are mainly used in industries such as construction, light industry, automobile, agriculture, animal husbandry, fishery, and commerce. The construction industry is mainly used for manufacturing anti-corrosion industrial and civil building roof panels, roof grilles, etc; The light industry uses it to manufacture home appliance casings, civilian chimneys, kitchen utensils, etc., while the automotive industry is mainly used to manufacture corrosion-resistant components for sedans, etc; Agriculture, animal husbandry, and fishery are mainly used as tools for grain sto
Price evaluation of steel bars (deformed steel bars)
In April, except for the northern region of China, the domestic price was 3850-3880 yuan per ton
From 3920-3950 yuan per ton in April, it decreased to 70 yuan per ton.
Steel mills reduce production due to losses or low profits
Sources say there is a pessimistic expectation of a recovery in demand in May.
The weekly production of threaded steel at major steel mills is 2.94 million tons, which is higher than
As of Thursday, there was a decrease of 73800 tons compared to the previous week,

China's steel export prices continue to decrease
According to Mysteel's understanding, the prices of long timber in Asia have continued to decline recently. The market has heard that a Vietnamese factory has recently reached an export transaction for rebar to Hong Kong and Singapore, with prices of $645 per ton of CFR real weight and $630 per ton of CFR weight, respectively. The completion of this transaction has prompted the import level of rebar in Southeast Asia to continue to decline.

The price of domestic hot coil in Europe is stable, and the competitiveness of imported resources is increasing
Market transactions were slow this week due to the European Easter holiday (April 1-April 4). Nordic mills once wanted to raise the price of hot coil to €900/t EXW ($980/t), but the feasible price is expected to be around €840-860/t. Affected by the two fires, some of ArcelorMittal's hot coil supply was interrupted, which affected southern European customers who had ordered hot coil before, and buyers had to seek imported hot coil resources. The delivery period of hot coil resources
