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:The distinction between flat steel and steel strip
Flat bar is strip, mostly 30*3, 40*4, 50*5 and so on. Strip: Blue (sometimes called black) is a chemical treatment, the surface to form a dense oxide film, corrosion and decoration;
Q:The function of ground lead out galvanized flat steel
Use and test, debug, you must use lead line.In accordance with the D501 specification, its cross section is not less than 4*40
Q:Lightning protection grounding, what is called three surface welding?
Lightning protection, grounding, the three sides of the welding:The buried depth of the grounding body shall not be less than 1m at the top, and the steel pipe grounding body shall be vertically configured.The length of the vertical grounding body shall not be less than 2.5m, and the spacing between them shall not be less than 5m.
Q:What is the weight calculation formula for galvanized flat steel and galvanized steel angles?
That is volume * density = weight.For example: L50*5 angle, general case, hand count is (0.05*2-0.005) *0.005*7850=3.729kg/m; 6m is 3.729*6=22.37kg [formula is W= (both long - and angle angle thickness) * angle thickness *7850* meters, of which 7850 were iron density value after conversion unit after multiple values, namely 7850kg/m3. The length and thickness and the number of meters into units are in meters, the weight of the unit is kg W.
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:What is flat steel, please?
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:Can lightning protection earthing steel bar be directly welded with thread steel?
Yes, but the length of the weld must be greater than or equal to 6 times the length of the steel bar, double sided welding. If one side welds, double the length of the weld. Otherwise, lightning acceptance is not up to standard.
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:What is flat steel for?
Forged flat steel is a forged strip of steel with a rectangular cross section. Forging injustice can get certain shape and size and forgings, casting microstructure of the steel is remarkably improved, increase the density of steel; can change the distribution of the fiber structure, clear anisotropy, improve the mechanical properties of the metal, so that the strength and toughness of steel are improved; and it can be used to process the plastic lower high Shuogang and high alloy steel. Forged flat steel is mainly made of high quality alloy steel, mainly used as springs, tools and important mechanical parts. The specification for wrought flat steel is expressed in millimeters of thickness * width. The specification is 20mm*40mm~160mm*300mm.
