Q:Is the earthing electrode made of galvanized flat steel or bare copper wire?
The combination of conductors or conductors that are buried in the earth so as to connect with the earth is called a ground electrode. The grounding electrode is the electrode which is in full contact with the ground and realizes the connection with the earth. In the electrical engineering, the grounding electrode is made of a plurality of 2.5M long, 45X45mm galvanized steel angles, and is nailed at the bottom of the 800mm deep groove, and then is drawn out with the lead out line.
Q:How many years can hot dip galvanized flat steel be used?
Experience has shown that the extent of atmospheric corrosion varies from region to region. The service life of hot-dip galvanized flat steel is different in different environments.
Q:What's the difference between stainless steel flat bar 304 and 316
Stainless steel flat bar is one of the shape steel, 304 stainless steel flat steel, generally divided into hot-rolled flat steel and cold drawn flat steel. The general delivery state of hot-rolled 304 stainless steel flat surface is pickling, cold drawn 304 stainless steel flat surface, general delivery state for wire drawing and polishing.There are many kinds of steel, it is a kind of solid strip steel with definite section shape and size. It is divided into two kinds of simple and complex sections according to their cross section shapes. The former includes round steel, Fang Gang, flat steel, six angles and angle iron. The latter includes rail, I-beam, channel steel, window frame steel and special-shaped steel.
Q:Difference between cold drawn flat steel and flat steel
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. 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:What is the representation of flat steel?
In use, it has advantages over steel platesFlat steel adopts negative deviation rolling, but according to actual weight, the utilization ratio of steel plate is 1~5 percentage points higher than that of steel plate.Flat can according to user needs, set the thickness, width and length of production, for the user to reduce the cut and save processes, reducing labor, material consumption, but also reduce the loss of raw materials processing, time saving, material saving. Products have been specialized in steel structure manufacturing, machinery manufacturing, automotive industry, mining machinery, lifting machinery and other industrial materials.
Q:What do the numbers in the steel HN346*174*6*9 refer to?
Large steel: large steel, I-beam, channel steel, angle steel and flat steel are hot rolled, round bar, Fang Gang, six angle iron in addition to hot rolling, there are forging, cold drawn and so on.
Q:Why do some buildings need a steel bar around the top?
Round steel (grade 1 steel) belongs to ordinary low carbon steel with low strength. However, the plasticity of the round bar is stronger, that is, the round steel has a larger deformation before it is pulled off.It has been widely used in the fields of hardware, construction, automobile, shipbuilding, petrochemical, machinery, medicine, food, electricity, energy, space, etc.. The most extensive machining of general machine parts, general rod type steel parts, CD pole, bolt, nut.Refers to the galvanized flat steel width 12-300mm, thickness 4-60mm, cross section is rectangular and with pure edge of galvanized steel. Galvanized flat steel can be finished steel, also can be galvanized pipe blank and galvanized belt. With high strength, light structure: strong grid welding structure, so that it has high load, light structure, easy lifting and other features, beautiful appearance, durable.
Q:-40x4 hot galvanized flat steel, a water 1m, what do you mean?
The protective layer to protect the housing outside the gutter and rain water is the life of the building apron. The water is hot galvanized flat steel by this protective layer 1 meters. Hope to be of help to you!
Q:Between the MEB and the power distribution cabinet with wire with the flat and why
How many will do is a box, the basement has the condition to make the ring to spread the flat steel (copper) to take one circle, many places reserve the ground terminal box foundation to attract, the access flat steel belt;
Q:How to use -40*4 galvanized steel bar to do grounding electrode?
The -40*4 galvanized flat steel is used as the grounding electrode, and the horizontal grounding electrode needs to be welded with the lead wire.
