Q:Cold rolled flat steel standard. What is cold rolled flat steel?
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.
Q:Why is it better to use round steel than that of flat steel in lightning protection?
From the cross section, thermal stability as long as meet the discharge current can be, but from the lightning protection downlead selection, selection of round steel in order to prevent the tip discharge, so we generally do not choose flat edges as grounding, buried in the earth round and not flat how much difference, but in the same section of the case, of course, the contact area of flat steel and soil are large, relatively scattered large flow area, the construction is more convenient, in terms of price, we are willing to use flat, as for the problem of anti-corrosion, anti-corrosion paint, zinc can be taken, you know the thickness of galvanized steel pipe is generally not flat, so it really depends on the term for the use of galvanized flat steel is not bad.
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:What is the surface area of flat steel 100*3 meters per metre?
2X (0.1x1+0.003x1+0.1x0.003) =0.2066 with a surface area of 0.2066 square meters.Flat, refers to the width 12-300mm, thickness 4-60mm, cross section is rectangular in shape and with a blunt edge of steel.
Q:How many steel tubes can be used instead of 60 * 10 flat steel?
It can also be hardened by machine speed. Good weldability. The abrasion resistance and fatigue strength are better than 304 stainless steel.
Q:50*4 hot dip galvanized flat steel can be used as grounding. How many square feet can be used instead of ground wire?
GB is not 50*4, but 4*40; International Electrotechnical union IEC is 3*25 can also, and if it is small houses, GB only 6mm diameter of it. It can be seen that the size of flat steel is mainly due to the consideration of mechanical strength and more than the consideration of electrical performance
Q:What about the installation height of the socket and the height of the ground flat steel?
If the construction unit, design institute and contact Party A drawings or design change
Q:What's the difference between hot rolled flat steel and flat rolling tool flat steel?
Hot rolled flat steel rolling tools - tool steel, commonly used for measuring and cutting tools with what. Material is tool steel, such as carbon tool steel (T8, T10), alloy tool steel (Cr12MoV), high-speed steel, etc..
Q:Do lightning protection, lead out of the galvanized round steel, flat steel needs to be inspected?
No, when purchasing hot galvanized round steel and flat steel, please offer the factory certificate and inspection certificate.
Q:What is 40x4 galvanized flat steel, please?
Main application: galvanized flat steel is used as material, used for making iron, tools and machinery parts. It is used as frame, structure and escalator for building.
