The difference between staircase truss square steel tube and angle steel
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.
The tube, as the name suggests, it is a square shaped tube type, many kinds of material material can form a square body, it is medium in, what, in what place, most square to steel for the majority, for the structure of the tube, decorative tube, square building.Square tube is a square tube of a name, that is, the length of the same steel pipe. The strip is rolled by process. Generally, the strip is disassembled, leveled, crimped and welded to form a round tube, then rolled from a tube into a square tube and cut to the required length. Usually 50 bags each.
Square steel tube, large diameter thick walled square steel tube, square steel tube, seamless square steel low alloy square steel tube, 135*135*10 square steel tower with square steel tube, Q345B low alloy square steel pipe, seamless steel pipe 20# square
Square steel tube and steel materials are the same, the shape is not the same, the steel is generally square, as the basic structure of escalator truss, angle is generally 90 degrees or other special angle as connections;
