Channel structure, angle steel, I-beam and so on, if not painted, the impact on life?
With the continuous improvement of the quality of engineering, steel structure steel, steel, steel and other sections shall be made and preserved in use, if not treated will have great influence on the service life of workpieces. From the point of view of comprehensive cost and effectiveness of anti-corrosion treatment, hot-dip galvanizing, which is called "Iron Guard", should be the first choice for corrosion protection. The paint can only be used as protective treatment of the short term, it is low cost, fast construction but every 1-2 years for a brush maintenance, time-consuming late high cost galvanizing treatment at a time can keep 30-50 years or even permanent, because this has a great relationship with it service environment, coastal and inland, heavy industry District and country are very different.
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.
Influence, without paint, easy to rust, will reduce life, strength will be affected.
The influence will reduce the life span
