Production Flow of Mild Steel Flat Bar

The Mild steel flat bar is made through three processes:

1.Feeding the material: Feeding the row material (the steel plate) to Slitting Line.

2.Slitting:The steel plate would be slitted into expected width by lengthways cutter.

3. Leveled and cutting: The plat bar would be ground into level by the grinder and then cut into required length

Q:How many years can hot dip galvanized flat steel be used?
Coastal areas usually refer to a region within a mile of the sea. The ocean atmosphere can spread deeper inland, especially on islands. The prevailing winds come from the ocean, and the climate is bad. If the wind is mixed with ocean fog, especially due to evaporation and accumulation of salt deposits, coupled with less rain and less frequent rain erosion, coastal conditions will be even more unfavourable. If there is any industrial pollution, there is more corrosive. Hot galvanized flat steel in such circumstances, usually 20 years or so.
Q:What's the difference between stainless steel flat bar 304 and 316
From the metallography point of view, because the stainless steel contains chromium, the surface forms a very thin chromium film, which separates from the oxygen penetrated by the steel.
Q:How can copper clad steel ground electrode and galvanized flat steel be welded?
Using hot fusion welding. It is welded firmly and will not corrode the weld because of electrochemical action.The common copper clad steel wire electrode is copper wire.
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 the use of slitting flat steel?
Flat cut flat steel, also called fine shearing flat steel strip, can be used to produce iron, tools and mechanical parts, and is used as frame structures and escalators for buildings.
Q:Hot dip galvanized flat steel specification 40X4, 60X6 meaning?
Hello Hot galvanized flat steel specification 40* 4 stands for flat steel with a height of 40 mm and a thickness of 4 mm60* 6 stands for flat steel with a height of 60 mm and a thickness of 6 mm..
Q:Building poles, outdoor flat steel, the deeper the buried depth, the better?
The construction of outdoor flat steel at normal negative 1.5m or so, there is design requirements. Nor does it mean that the deeper the better. The main function of the outdoor ground flat steel is that when the lightning resistance of the main body of the building is not up to the design requirements, the artificial outdoor triangular steel pipe pile shall be added to the outdoor earthing flat steel until the ohm value is qualified. Normally, the outdoor ground flat steel does not work.
Q:The difference between use and performance of hot rolled flat steel and longitudinally cut flat steel is discussed
Its manufacturing process determines the poor dimensional accuracy of hot-rolled flat steel.Vertical shearing flat steel (fine shearing flat steel strip):The raw material board is produced by a larger factory, the raw material source is controllable, the material can be basically guaranteed, and the mechanical performance can basically meet the relevant GB standards.The dimension of vertical shear flat steel is relatively high.
Q:Why is it better to use round steel than that of flat steel in lightning protection?
Presumably, it's a discussion, not an answer.At the same length and with the same cross section,(1) the contact area between flat steel and earth is slightly larger.(2) flat steel is easier to bend than round steel, so it is more convenient to construct.(3) flat steel is easier to connect with bolt by connecting bolt.
Q:Connect the equipotential terminal box to the ground flat iron. Can I use plain flat steel?
Equipotential terminal box is the protection main buildings, water gas pipes, heating and refrigeration, cooling system, link building components such as metal parts, in order to meet the anti shock protection requirements of the electrical contact voltage of less than 50V. Is an important component of modern building electrical appliances, is widely used in high-rise buildings.
