As for the delivery time, it can be controlled by the customer. Because we are a physical factory and cooperate with many large steel mills in China, the time error can be controlled within about 3 days, and we provide free warehousing service

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. 

First, the construction field

In construction projects, hot-dip galvanized rectangular tubes are mainly used as an important part of building drainage systems and ventilation pipes, such as: indoor drainage systems, building drainage systems, rainwater pipes, etc. In the steel structure, the hot-dip galvanized square pipe as the joint pipe between the beam and column can play a very good supporting role. In addition, in the fire protection system of buildings, hot-dip galvanized rectangular tube also plays an important role, such as it is used to make fire doors and Windows, fire partitions and so on.

2. Bridges and transportation

In bridge construction, hot-dip galvanized rectangular tube is often used in the manufacture of bridge drainage system and bridge guardrail. In addition, in traffic engineering such as highways and railways, hot-dip galvanized rectangular tube are widely used to make bridge signs, guardrails and pipelines for conveying goods.

3. Agriculture

In the agricultural field, hot-dip galvanized rectangular tube are mainly used to manufacture agricultural machinery and equipment, such as pumps, water pipes and their accessories. In buildings such as agricultural greenhouses, hot-dip galvanized rectangular tube as a skeleton can effectively enhance durability and stability.

4. Petrochemical industry

In the field of petrochemical industry, hot-dip galvanized rectangular tube is widely used in oil fields, chemical plants, natural gas pipelines and other fields. Hot-dip galvanized square pipe can be used as a pipeline for transporting oil and gas, and its corrosion resistance and good sealing characteristics can effectively protect the oil and gas inside the pipeline from being polluted.

In industrial production and civil life, hot-dip galvanized rectangular tube has a wide range of applications. Because the hot-dip galvanized rectangular tube has the characteristics of anti-corrosion and corrosion resistance, it can be used in harsh environments for a long time. Through a brief introduction to the application field of hot-dip galvanized rectangular tube, I believe readers will have a clearer understanding of the application scenario of hot-dip galvanized rectangular tube.
