Most elements in the air will cause corrosion of metal materials, so when storing GB/T1591 Q345B angle steel, it is better to store the angle steel in a clean and dry place to avoid humid air, increase the appearance of corrosion and rust spots on the GB/T1591 Q345B angle steel, and lose the use value.

No matter what kind of angle steel is, the specification and size are inconsistent, so GB/T1591 Q345B angle steel should be stored according to the principle of classification, so as to facilitate the direct use of the latter. Don't mix it with other items.
