ASTM A53 Tube Hollow Section Rectangular Square Gi Pipe Zinc Coated Q195 Q235 Q345 Hot Dipped Galvanized Steel Pipe Tube

ASTM A53 Tube Hollow Section Rectangular Square Gi Pipe Zinc Coated Q195 Q235 Q345 Hot Dipped Galvanized Steel Pipe Tube Zhengde Galvanized steel pipes are divided into cold-galvanized pipes and hot-dip galvanized pipes. According to the shape, they are divided into galvanized round pipes and galvanized square rectangular pipes. Both the substrate and the coating are combined. Hot-dip galvanizing is to pickle the steel pipe first. In order to remove the iron oxide on the surface of the steel pipe, after pickling, it is cleaned by ammonium chloride or zinc chloride aqueous solution or a mixed aqueous solution of ammonium chloride and zinc chloride, and then sent to hot-dip coating tank. Hot-dip galvanizing has the advantages of uniform coating, strong adhesion and long service life.

Galvanized round pipe
Galvanized round pipe is a common building material, mainly used in indoor and outdoor pipes, electrical wiring, ventilation pipes and mechanical structures and other fields. It has the characteristics of corrosion resistance, wear resistance, high strength, easy processing and installation, so it is widely used in various fields. In the field of construction, galvanized round pipes are mainly used for water and electricity pipes, HVAC systems and fire pipes, etc.; in terms of mechanical structures, they can be used as machine parts, auto parts and steel structures; in terms of furniture manufacturing, they can be used for manufacturing Table chairs and bed frames etc. In short, galvanized round pipes are very versatile and can meet the needs of various fields.

Galvanized Square Tube
Galvanized square pipe is a kind of steel pipe with anti-corrosion function, which is suitable for construction, structure, electrical,
Public services, automobile manufacturing and many other industries. Specific uses include:
1. Construction field: underground pipelines, outdoor and indoor building pipelines, building structures, decorative materials
wait.
2. Electrical field: power lines, communication lines, cable sheaths, generator sets, etc.
3. Machining: Simple operation and convenient operation, so it is widely used in machine tools, automobile manufacturing,
Food machinery and other fields.
4. Public services: highway tunnels, green belts, park squares, etc.

Qquality assurance
To choose a steel pipe company with product quality assurance, judge whether the company meets the relevant national production standards and quality standards by inquiring about the company's production license certificate, quality certification certificate and other details. Secondly, pay attention to the quality of the steel pipe, whether there are cracks, bubbles and other defects on the surface, and whether the product identification is complete and clear. In the process of use, it is also necessary to pay attention to regular cleaning to prevent the steel pipe from rusting and other phenomena, so as to prolong the service life of the steel pipe.

Galvanized steel pipe application
Galvanized steel pipe refers to a pipe coated with a layer of zinc on the surface of ordinary steel pipes to form a protective layer to prevent corrosion of steel pipes. Its corrosion resistance and mechanical properties are much better than clarinet and seamless steel pipes, and its appearance is more beautiful. It is widely used in construction, machinery, chemical industry, electric power and other industries. Zhengde galvanized steel pipe is a commonly used building material and is widely used in construction, industry and rural areas. For steel pipes, safety and quality are the most critical factors. The standard is to ensure the safety, quality and order of steel pipes.

Quality first: production and inspection in strict accordance with production standards;
Price advantage: discounts based on real market prices;
Transaction security: There will be no loss of customer funds;
After-sales guarantee: the customer's problem is our problem;
Long-term cooperation: quality assurance, price advantage, sincere service can last for a long time.
