Quality and advantages of galvanized steel pipe in Shenzhen Steel Works

Quality and advantages of galvanized steel pipe in Shenzhen Steel Works

advantage
1. Low processing cost: the cost of hot dip galvanizing rust is lower than that of other paint coatings;
2, durable: hot-dip galvanized steel pipe with a surface gloss, uniform zinc layer, no leakage plating, no drip, strong adhesion to break the net regiment, strong corrosion resistance, sharply rise in the suburban environment, standard hot-dip galvanizing The rust-proof thickness can be maintained for more than 50 years without repairing; in urban or offshore areas, the standard hot-dip galvanized rust-proof layer can be maintained for 20 years without having to be repaired;
3, good reliability: between the galvanized layer and the steel is a good news of metallurgical bonding, becoming part of the galvanized steel pipe on the steel surface, so the durability of the coating is more reliable;
4. The toughness of the coating: The galvanized layer forms a special metallurgical structure that can withstand mechanical damage during transportation and use;
5, comprehensive protection: each part of the plated parts can be plated with zinc, even in the depressions, sharp corners and hidden places can be fully protected;
6, save time and effort: the galvanizing process is faster than other coating construction methods, and can avoid the time required to paint on the construction site after installation.
Appearance quality The surface quality of angle steel is specified in the standard. Generally, there is no tendency to develop harmful defects such as delamination, crusting, cracks, etc.
The allowable range of the angular deviation of the angle steel is also specified in the standard, and generally includes investment advice such as bending degree, side width, side thickness, apex angle, and theoretical weight, and the angle steel is not required to have significant torsion.
Use galvanized steel pipe for general use with electric iron towers, communication towers, curtain wall materials, shelf construction, railways, highway protection, street light poles, marine components, construction steel structural members, substation ancillary facilities, light industry, etc. Recommended by the Square Tube Association.
Sites or warehouses in which galvanized steel pipes are placed in the Shenzhen Steel Plant should be cleaned and drained away from factories and mines that generate harmful gases or dust. Remove weeds and all debris from the site and keep the galvanized steel pipes clean. In the warehouse, it is not allowed to pile up with the corrosive materials such as acid, alkali, salt and cement. Square tubes of different varieties should be stacked separately to prevent confusion and prevent contact corrosion. Large sections of steel, rails, insult steel plates, large diameter steel pipes, forgings, etc. can be stacked in the open air. Some small square tubes, thin steel plates, steel strips, silicon steel sheets, small caliber, galvanized embedded parts or thin-walled steel tubes, various cold-rolled, galvanized steel pipes, and high-priced, corrosive metal products can be stored in the warehouse. . The warehouse should be selected according to the geographical conditions. Generally, the general closed warehouse is used, that is, the warehouse with the wall, the doors and windows is tight, and the ventilation is provided.
