What is black sheet and why is it important in the industry?
Black sheet production process in workshops and factories
Types of black sheet grades and their uses
- Normal black sheet (ST37): This type of sheet, which has a lower carbon percentage, is very suitable for construction and shed construction. Due to its relative softness and excellent welding ability, it is widely used in building skeletons.
- Industrial black sheet (ST52): This sheet has more carbon and manganese and has a much higher resistance than the normal type. Therefore, it is used in heavy industries, dam construction, construction of pressure tanks and bridge construction.

Factors affecting the price of black and galvanized sheet in Tehran
The price of iron is always influenced by many factors. For major buyers and contractors, knowing these factors is very important for purchasing timings.
Currency fluctuations and global steel prices
Since steel is a global commodity, its base price is determined based on the dollar rate and global prices of steel ingots. Any fluctuation in the currency market directly affects the cost price of the sheet in Vastig Production Workshop and other sellers.
Sheet thickness and dimensions
Sheets are produced in different thicknesses (from a few tenths of a millimeter to a few centimeters). Naturally, the greater the thickness, the weight of the sheet and its final price will increase. Black sheet is usually supplied in rolls and sheets in standard sizes of 12 meters, 1.252.5 meters and 6x1.5 meters.
Manufacturing plant
The sheet manufacturer's brand plays an important role in the price. For example, galvanized sheet produced in reliable domestic factories may have a different price than different samples due to the higher quality of zinc coating. Vastig production workshop has complete transparency about the brand of sheet delivered to the customer and guarantees the authenticity of the product.

The importance of choosing a first-class sheet in reducing hidden costs

The use of low-quality black sheet in the building frame can endanger the security of the structure. Also, the use of galvanized sheet with low coating in humid environments causes the sheet to rust prematurely and need to be replaced, which imposes heavy maintenance costs.
