What is hot-dip galvanized pipe
Hot dip galvanized pipe is the reaction of molten metal with iron matrix to produce alloy layer, so that the matrix and the coating are combined.
Hot dip galvanizing is to first pickling the steel pipe, in order to remove the iron oxide on the surface of the steel pipe, after pickling, through ammonium chloride or zinc chloride aqueous solution or ammonium chloride and zinc chloride mixed aqueous solution tank for cleaning, and then into the hot dip plating tank.
Hot dip galvanizing has the advantages of uniform coating, strong adhesion and long service life. The matrix of hot dip galvanized steel pipe and the molten bath undergo complex physical and chemical reactions to form a tight zinc-iron alloy layer with corrosion resistance.
The alloy layer is integrated with the pure zinc layer and the steel pipe matrix, so its corrosion resistance is strong.
Handle design
Galvanizing refers to the surface treatment technology of plating a layer of zinc on the surface of metals, alloys or other materials to play the role of aesthetics and rust prevention. The main method used is hot-dip galvanizing.
Zinc is soluble in acids and alkali, so it is called an amphoteric metal. Zinc changes little in dry air. In moist air, a dense basic zinc carbonate film forms on the surface of zinc. In the atmosphere containing sulfur dioxide, hydrogen sulfide and Marine atmosphere, zinc corrosion resistance is poor, especially in the high temperature and high humidity atmosphere containing organic acid, zinc coating is easily corroded.
The standard electrode potential of zinc is -0.76V, for the steel substrate, zinc coating belongs to the anodic coating, which is mainly used to prevent the corrosion of steel, and its protective performance is greatly related to the thickness of the coating. The protection and decoration of zinc coating can be improved significantly after passivation, dyeing or coating with light protector.
Our product features
Hot-dip galvanized flat steel refers to galvanized steel with a width of 12-300mm, a thickness of 4-60mm, a rectangular section and a slightly pure edge. Hot-dip galvanized flat steel can be finished steel, and can also be used as blank and galvanized tape for galvanized pipes.
Main uses: hot-dip galvanized flat steel can be used as a material for hoop iron, tools and mechanical parts, and used as building frame structural parts and escalators.
Product advantages
1. Special product specifications. The thickness is 8 ~ 50mm, the width is 150-625mm, the length is 5-15m, and the product specification file distance is dense, which can meet the needs of users, and can be used instead of the middle plate, without cutting, and can be directly welded.
2. The product surface is smooth and clean. High-pressure water descaling process is used twice in the process to ensure smooth steel surface
3. The two sides are vertical and the water corners are clear. Two vertical rolling in finishing rolling ensures good verticality, clear Angle and good surface quality of both sides.
4. The scale of the product is accurate, the three-point difference, the level difference is better than the steel plate standard; The product is flat and straight, and the plate shape is good. Finishing rolling adopts continuous rolling process, automatic loop automatic control, to ensure that no stacking steel does not pull steel, product dimensional accuracy is high, tolerance range, three point difference, the same strip difference, sickle bend and other parameters are better than the plate, and the plate straightness is good. Cold cutting, high precision length measurement.
5. The product material adopts the national standard, the same as the steel plate. Quality and technical standards according to YB/T4212-2010 standard organization of production (Q345B/Q235B refer to GB/T1591-94, GB/T700-88 standards respectively)

Advantages of hot dipped galvanized
The main advantages are: low treatment cost: the cost of hot dip galvanized rust prevention is lower than that of other paint coatings; Durable: In the suburban environment, the standard hot-dip galvanized rust prevention thickness can be maintained for more than 50 years without repair;
In urban or offshore areas, the standard hot-dip galvanized anti-rust layer can be maintained for 20 years without repair;
Good reliability: the galvanized layer and the steel is a metallurgical combination, becoming a part of the steel surface, so the durability of the coating is more reliable;
The toughness of the coating is strong: the galvanized layer forms a special metallurgical structure, which can withstand mechanical damage during transportation and use;
Comprehensive protection: Every part of the plating can be plated with zinc, even in the depression,
Sharp corners and hidden places can be fully protected; Save time and effort: The galvanizing process is faster than other coating methods and avoids the time required to apply on the site after installation.
The application range of hot-dip galvanized steel flat bar
1, galvanized flat steel features: high strength, light structure: solid grid pressure welding structure makes it have high load, light structure, easy to lift and other characteristics; Beautiful appearance, durable.
2, galvanized flat steel use: widely used in petrochemical, power plant, water plant, sewage treatment plant, municipal engineering, sanitation engineering and other fields of platform, walkway, trestle, ditch cover, manhole cover, ladder, fence, guardrail and so on.
