Q:What is the negative deviation allowed by the national standard for galvanized flat steel of 40*4?
40 is the width of the section steel, 4 is the thickness of the steel, and the unit is mm.Flat, refers to the width 12-300mm, thickness 4-60mm, cross section is rectangular in shape and with a blunt edge of steel. Flat steel can be finished steel, or can be used as the blank of welded pipe and thin slab for laminated sheet rolling.
Q:What do the numbers in the steel HN346*174*6*9 refer to?
Small steel: small steel, middle, round, square, flat steel processing and use, similar to large steel, small diameter round steel is often used as building steel.
Q:What is the thickness deviation of 40*4 galvanized flat steel?
Main application: flat steel is used as a material, used for making iron, tools and machinery parts, and used as frame structures and escalators for buildings
Q:Earthing flat steel, width, overlap face, bolt, big country net
Usually 4 x 40 flat steel, you definitely won't use 6mm screw, but I use two 8mm screws to connect the strength of not less than 12mm of A.
Q:How can copper cables and flat steel be welded together?
The copper cable is pressed into the nose. It is punched through the steel and screwed,The national standard atlas is connected with a total equipotential terminal box.
Q:How large is the flat steel used for equipotential grounding?
According to the GB 50054-2011 3.2.15 6# responses (table 3.2.15), the distribution system of equipotential bonding conductor may be 25mm2 copper; when the 1/2PE line section of not less than the case, must use 25mm2 copper (or the equivalent capacity of aluminum or steel); according to the GB 50057-2010 5.1.2 (table 5.1.2), lightning protection system equipotential bonding conductors with 16mm2 copper, can meet the minimum section of all the connecting parts of the requirements of lightning protection device.
