Galvanized steel tube

In modern agriculture, greenhouses are essential for optimizing crop growth and protecting plants from harsh environmental conditions. Among the critical components of greenhouse structures, galvanized steel tubes stand out for their durability, corrosion resistance, and cost-effectiveness. This article explores the technical specifications, international standards, applications,

As an important metal material, galvanized square tubes are widely used in construction, machinery, transportation, municipal administration and other fields due to their excellent corrosion resistance, high strength and aesthetics. 1. Material and steel grade The base material of galvanized square tubes is mainly carbon

There are several common surface treatment methods for steel pipes. The process, characteristics and uses of each treatment method are as follows: 1. Hot-dip galvanizing - Process: Immerse the steel pipe in molten zinc liquid to make the zinc adhere to the surface to form

In the past month, China's steel industry has received a series of good news, especially in terms of rising billet prices, steady growth in steel pipe exports, and positive signs in future steel pipe price forecasts. 1. Billet price trend Since September, China's billet market

DIN standard (Deutsches Institut für Normung, German Institute for Standardization) is a technical standard system for steel pipes and other materials in Germany. DIN standard is the national standard of Germany and is widely used in the manufacture of various materials and industrial products, including

ASTM (American Society for Testing and Materials) standards are widely used internationally, covering the chemical composition, mechanical properties, manufacturing process and other requirements of various materials. In the field of steel pipes, ASTM standards have specific specifications for different types of steel pipes. The following

In the manufacture of metal facilities, hot-dip galvanizing and cold-dip galvanizing are two commonly used manufacturing processes. As a metal anti-corrosion method, hot-dip galvanizing usually puts the steel structure to be derusted into the molten zinc at about 500 °C, so that the zinc layer

Galvanized steel pipe refers to a steel pipe with a layer of zinc on the surface to achieve the effect of corrosion and rust prevention. Galvanized steel pipe is widely used in manufacturing industries such as construction, machinery, coal mining, chemical industry, railway vehicles, automobile

The main purpose of galvanizing steel pipes is to improve their corrosion resistance. Galvanizing is a process that covers the surface of steel pipes with a layer of zinc. This zinc coating can provide good protection for the steel pipes. The following are the main
