Q:Double angle steel rod in the corners of the roof steel why need to set the plate?
A rod is a member of a much larger dimension than a horizontal (vertical) direction. The beams, columns and other components in the building are generally abstracted as rods. The shape and size of the rod can be described by two major geometric elements, the cross section and the axis of the rod. A cross section is a vertical section perpendicular to the length of the bar, and the axis is the center of each cross section. The cross section and the axis of the rod are perpendicular to each other. A rod with the same axis and straight line and cross section is called a straight rod with equal section. Building mechanics and mechanics of materials are mainly concerned with equal section straight bars. The bar whose cross section changes along the axis is called a cross section bar.
Q:What is the difference between galvanized steel bar and ordinary angle iron?
Plain angle ironThe surface quality of ordinary angle iron is stipulated in the standard, and no harmful defects such as layering, scab and cracks are required.The allowable range of the geometric deviation of the angle iron is also stipulated in the standard. The bending angle, the width of the edge, the edge thickness, the vertex angle and the theoretical weight are generally included, and the angle steel must not be significantly reversed.Angle steel is a kind of carbon structural steel for construction. It is a simple section steel, mainly used in the frame of metal component and workshop. In use, better weldability, plastic deformation and mechanical strength are required. The raw steel billet for producing angle steel is low carbon square billet, and the finished product angle iron is made by hot rolling, normalizing or hot rolling.
Q:What is 4# angle iron? What are the classifications of angle iron? What are the specifications? Thank you
Angle called angle, the steel strip is perpendicular to each other on both sides into the corner. There are equal angles and unequal angles. The two sides of an equal angle steel are equal in width. The specifications are expressed in millimeters of edge width * edge width * edge thickness. Such as "/ 30 x 30 x 3", that is 30 mm width equal angle, edge thickness of 3 mm. Also available models that model is the number of centimeters wide, such as angle 3#. The model does not mean the size of the different edges and sizes of the same model. Therefore, the width, the edge and the thickness of the angle iron should be filled out in the contract and other documents, so as not to be indicated by the model alone. Standard Specification for hot-rolled equal angle iron is 2#-20#. The angle iron can be made up of different force components according to the different structure, and can also be used as the connecting piece between the components. Widely used in a variety of architectural and engineering structures, such as beams, bridges, towers, hoisting and conveying machinery, ships, industrial furnace, reaction tower, container frame and warehouse.
Q:What is the use of angle steel and channel steel?
Most of the channels are made of trays and cabinets, as well as stationary supports, such as power plants and substations.
Q:How many meters is one angle steel?
Standard Specification for hot-rolled equal angle iron is 2#-20#. The angle iron can be made up of different force components according to the different structure, and can also be used as the connecting piece between the components. Widely used in a variety of architectural and engineering structures, such as beams, bridges, towers, hoisting and conveying machinery, ships, industrial furnace, reaction tower, container frame and warehouse.
Q:Which is cheaper, angle iron and steel pipe?
Steel pipe is not only used to transport fluid and powder solid, exchange heat energy, and manufacture mechanical parts and containers, but also is an economic steel. It can reduce weight and save 20 to 40% of metal by using steel pipe to make building structure, network frame, prop and mechanical support. Moreover, it can realize factory mechanization construction. Using steel pipe to manufacture road bridge can not only save steel, simplify construction, but also greatly reduce the area of coating protective layer, save investment and maintenance cost.
Q:Bearing capacity of angle steel and channel steel
Channel steel is a strip of steel with a cross section. Section steel with groove shape.Channel steel is a kind of carbon structural steel used for construction and machinery. It is a complex section steel. Its cross section has a groove shape. Channel steel is mainly used in building structure, curtain wall engineering, mechanical equipment and vehicle manufacturing, etc.. In use, it requires better welding, riveting performance and comprehensive mechanical properties. The raw material steel billet for channel steel is carbon or low alloy steel billets with a carbon content of not more than 0.25%. The finished channel steel is delivered by hot forming, normalizing or hot rolling. The specifications are expressed in millimeters of height (H) * leg width (b) * waist thickness (d), such as 100*48*5.3, which means waist height is 100 mm, leg width is 48 mm, waist thickness is 5.3 mm channel, or 10# channel steel. The same height of the channel, if there are several different leg width and waist thickness, also need to add a, B, C on the right side of the model to distinguish, such as 25#a, 25#b, 25#c and so on.Channel steel is divided into ordinary channel steel and light channel steel. Standard Specification for hot-rolled plain channel steel is 5-40#. Specifications for hot rolled flexible channel steel supplied by supply and demand agreement are 6.5-30#. Channel steel is mainly used for building structures, vehicle manufacturing, other industrial structures and fixed plates, cabinets, etc., and channel steel is often used in conjunction with i-beam.
Q:What is the keel of the aluminum single board suspended or the welded frame of angle steel?
The marking order of light steel keel is: product name, code name, width of section shape, height, steel plate thickness and standard number. Such as cross section shape is "C" type, width of 50mm, height of 15mm, steel plate thickness of 1.5mm ceiling keel marked: construction light steel keel.
Q:100 x 100 x 10 equal angle steel, per meter weight?
The weight of each metre is 15.120kg 8*15.120=120.96kgMethod for calculating weight of angle iron:Weight per meter =0.00785* (edge width + edge width - side thickness) * edge thicknessAngle called angle, the steel strip is perpendicular to each other on both sides into the corner. There are equal angles and unequal angles. Equilateral angle steelThe two sides are equal in width. Its specifications are edge width * edge width * edgeA thick millimeter representation.
Q:Angle iron specifications 125 * 80 * 101 m multiple
Angle iron specifications 125 * 80 * 10 weight: 15.3075kg/m.Angle called angle, the steel strip is perpendicular to each other on both sides into the corner. There are equal angles and unequal angles. The two sides of an equal angle steel are equal in width. The specifications are expressed in millimeters of edge width * edge width * edge thickness. Such as "/ 30 x 30 x 3", that is 30 mm width equal angle, edge thickness of 3 mm. Also available models that model is the number of centimeters wide, such as angle 3#. The model does not mean the size of the different edges and sizes of the same model. Therefore, the width, the edge and the thickness of the angle iron should be filled out in the contract and other documents, so as not to be indicated by the model alone.
