With the extension of service time, the steel frame is still inevitably damaged. Therefore, in order to prevent the steel grating from being damaged, it is very important to maintain the steel grating. Then what is the reason for the damage of steel grating?
In contrast, the damage rate of galvanized steel grating is still very low. Zinc coating is divided into hot-dip galvanizing and galvanizing. The difference is that the cost of galvanizing is low, but the thickness of zinc layer is not ideal; The cost of hot-dip galvanizing is low, but the thickness of zinc layer is not ideal; The cost of hot galvanizing is high, but the effect is good. Even if it is hot, the effect is better. Galvanizing is more durable, but it should be noted that during construction, galvanizing must be handled with care and not damaged.
The main losses of hot galvanized steel grating are as follows: due to the change of load and the change of steel grating for a long time, the structural bearing capacity is not enough, the steel grating is deformed, twisted and depressed, and various accidents lead to partial weakening, rod deformation, cracked connection, etc.
Cracking and warping of components or connections caused by temperature difference; The corrosion of chemical substances and serious electrochemical corrosion lead to the weakening of the section of steel lattice members, so it is best to use hot-dip galvanizing surface treatment in special cases; Other reasons: including the design and layout of steel grating, the production process of steel grating, and steel grating. Error, nonstandard and operation in board installation.
In short, the reasonable design, standard production, correct installation and scientific use of steel grating can make your steel grating truly durable, beautiful and cost-effective.
