JIS SS490 Structural Carbon Steel Angle

JIS SS490 Structural Carbon Steel Angle
JIS SS490 structural steel angle is popular choices for communication towers, factory warehouse, equipment supports and other industrial or engineering places. Compared with SS400, it is much stronger and effectively reduces weight and thickness for the same strength.

Mild SS490 unequal steel angle 
JIS SS490 hot-rolled carbon steel angle iron is available in black, zinc-coated or painted treatment. Owing SS490 is kind of common carbon steel which has no resistance to corrosion, so black is not recommended for the applications when the steel often contacts with water or corrosive airs. Painting will be also a good alternative. It can be painted any color to coordinate with the things all around.
