Q:Cold rolled flat steel standard. What is cold rolled flat steel?
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:Construction of lightning protection ground galvanized flat steel approach, need to retest test? What's the test?
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.
Q:The minus sign in front of what 40 galvanized flat steel
In front of a small cross is not a minus sign, but on behalf of the flat symbol. For example, the meaning of "-40*4" galvanized flat steel is: 40 is the width of the section steel, 4 is the thickness of the steel, and the unit is mm.
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:Is medium plate steel flat?
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 negative deviation allowed by the national standard for galvanized flat steel of 40*4?
40*4 galvanized flat steel GB permitted negative deviation value is the thickness deviation value is 0.2mm, the deviation 0.4mm, the width deviation value is the upper deviation 0.5mm, lower deviation 1.0mm
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:The difference between use and performance of hot rolled flat steel and longitudinally cut flat steel is discussed
Hot rolled flat steel (hot rolled flat steel strip):Mostly produced by small factories, the raw material sources are disordered and the material can not be guaranteed. Therefore, the mechanical properties of hot-rolled flat steel are greatly different. Hardness, tensile strength, elongation, weldability are often unpredictable.
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:Connect the equipotential terminal box to the ground flat iron. Can I use plain flat steel?
Connect the equipotential terminal box to the ground flat iron and cannot use plain flat steel. What level of ground steel must be used in AC electrical grounding standards, and must be hot-dip galvanized flat steel, the first is corrosion protection, and the second is long acting. Whether or not galvanized is always corroded, all national standards, industry standards, local standards are required to use hot-dip galvanized flat steel. And, depending on where it was buried, the size of flat steel was decided.
