Q:How to determine the application direction of steel grid plate
The width of the groove generally refers to the length of the steel grid (including the required width of the groove), and the width of the steel plate along the longitudinal direction of the groove
Q:Construction of electrical grounding steel flat buried anti-corrosion requirements, galvanized steel flat welding parts should be done anti-corrosion treatment, not welding parts are also doing anti-corrosion treatment?
Galvanized flat steel itself does not need additional corrosion protection.
Q:How to grounding lightning protection grounding?
In the lightning down the line corresponding to the outdoor depth of -0.8M, from being used as the lead line of the steel bar, welding a 40MM*4MM hot galvanized flat steel, this flat steel extended to the outdoor, from the outer wall distance of not less than 1.0M. For connecting equipotential band and adding artificial grounding body.
Q:Where can I buy ground level bending machine?
When lap welding is adopted, the welding length is as follows: 1. Galvanized steel bar is not less than 2 times its width, no less than three surface welding. When the width of flat steel is different, the length of lap should be wide. Before laying, the flat steel should be adjusted straight, simmer, bend not to die, straight line should not be obvious bending, and should stand upright. 2. The length of galvanized round steel shall be no less than 6 times of its diameter, and shall be welded on both sides (when the diameter is different, the lap length shall be of big diameter).
Q:How can copper clad steel ground electrode and galvanized flat steel be welded?
If you want it to work well, use heat release welding, and if you take into account the cost budget, there are connectors, connectors that are just mechanical connections
Q:Where is the use of flat steel in electrical use?
The main use of galvanized grounding in building electric device, equipotential connection, such as transformer neutral point grounding, power distribution cabinet repeatedly grounding of electrical equipment and protective metal pipeline grounding and equipotential connection of buildings, building the underground lightning belt (that is the root of a plurality of buried steel the grounding electrode connected), building lightning deflectors and high-rise building equalizing ring (without using the building structure reinforcement), cable bracket (laminated cable trench or substation room or subway) or slot (or tray tray) metal grounding connection, welding and in the use of bolt connection, look to determine the design requirements and conditions, generally buried (wall) welding used in concrete or concealed, must be at least three surface welding, welding (two flat lap length Larger than the width of flat steel 2.2-2.5 times, round steel and flat steel lap length is greater than round steel 6-8 times, welding mouth does not allow slag, meat and remove welding slag, welding finished, in addition to concrete, do anti-corrosion, rust prevention;
Q:What is 40x4 galvanized flat steel, please?
The 40 represents the width of the flat steel (the length of the two sides of the flat bar), and the 4 represents the edge thickness of the flat steel (the width of the flat steel edge).
Q:What is the rolling range of the micro cold rolled flat steel production line?
Flat steel, width 12-300mm, thickness 4-60mm, cross section is rectangular and with pure 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. Section steel is one of the four major steel products (plate, tube, mould, wire). According to the section shape, the section steel is divided into simple section steel and complex section steel (deformed steel). The former refers to the steel, round steel, flat steel, angle steel, six angle steel; the latter refers to the I-beam, channel steel, steel, steel, steel frame bending etc..
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:How is three grade steel connected to ground flat steel?
HRB400 can be directly welded by hand arc welding with Q235 flat steel into electrical circuit. (I have done two sets of tensile tests last year, qualified).
