Do you need paint for roof lightning proof steel bars?
The roof of the round steel as long as the welded joints painted anti rust paint is good, should not be painted a large area. When the flash device is made of steel material, hot-dip galvanized steel shall be used and corrosion resistant by zinc plating.
If the metal surface is coated with a thick layer of insulating paint, it will seriously affect the flashover effect. In the national standard, the metal roof is directly used as a flash receiver. The thickness of the paint used on the roof must be less than the required value. That is what it means.
The roof lightning protection round steel is the use of metal electrical conductivity and the principle of point discharge, the accumulation of the earth's electricity more rapidly spread to the air, play a role in lightning.
