As we all know, general steel is not corrosion resistant. In the open environment, it is easy to rust due to the temperature difference between day and night and humid environment. But this is not a problem for hot rolled profile steel. It is very common to place hot-rolled profile steel in the open air.

On the one hand, due to the large length and quantity of section steel, it is difficult to find a suitable warehouse for storage. On the other hand, even if you have a large enough warehouse, moving in and out of section steel is more troublesome, which will consume more manpower and waste time. Therefore, most manufacturers choose to put section steel in the yard. 

Manufacturers believe hot-rolled profile steel placed in the open air will be affected by outdoor weather, especially strong sunshine in summer and heavy rain and snow in winter. Although section steel is made of steel and is not easy to rust, its quality will still be affected if it is placed outdoors for a long time. 

Therefore, profile steel manufacturers should pay attention to controlling the output in daily production to ensure that the steel produced can be sold in time and avoid excessive inventory.
