Hot dip galvanized pipe:

With the development of the industry, hot dip galvanized products have been applied to many fields, the advantages of hot galvanizing gives a long anticorrosion service life and adapts to a very wide range of environments.Widely use and tower, communication tower, railway and highway protection, lamp posts, Marine structures, construction steel structure component, ancillary facilities of substation, light industry, etc.
 
Hot dip galvanized products have been applied to many fields as the industry developed, and the reason is simple: hot galvanizing gives a long anticorrosion service life and adapts to a very wide range of environments. Beyond greenhouse frames, the same pipe serves communication towers, railway and highway protection, lamp posts, marine structures, construction steel components and substation fittings. The figures below follow the corrosivity categories of ISO 9223 and BS EN ISO 14713-1, which classify a site by how fast zinc is consumed in that atmosphere: around 13 years in heavy industrial air (C4), about 30 years in city conditions (C3), around 50 years on the coast (C5), and 50 years or more without repair in a clean suburban setting (C2). Thickness, not the name of the process, decides which figure applies, so the coating thickness or zinc mass per square metre should be written into the order and can be confirmed before shipment.
 

Advantage:

1. Durable: a hot dip galvanized coating needs no site painting. In a clean suburban setting (ISO 9223 class C2) a standard coating goes 50 years or more without repair, and even in urban or coastal air (class C3 to C5) it still holds around 20 to 30 years before the first maintenance.

2. Good reliability, galvanized layer and steel is metallurgical combination between, become a part of the steel surface, thus the durability of the coating is more reliable.

3. The toughness of the coating is strong: galvanized layer to form a kind of special metallurgical structure, this structure can withstand the mechanical damage when transporting and using.

4. Comprehensive protection: each section of the plated parts can zinc plating, even in the cavity, sharp corners and hidden can be fully protected.

5. Save time and effort: galvanized process faster than other coating construction method, and can avoid the time needed for installation at the site after brushing.
 
6. Low initial cost: in general, the cost of the hot-dip zinc is lower than on other protective coating, the reason is very simple, other protective coating, such as sand and paint is labor intensive, and hot dipping zinc process for high mechanization, tightly controlled plant construction.
 
7. Simple test: hot-dip zinc layer can be visual and simple nondestructive thickness test table. We are factory professional in hot dip galvanized metal for above 35 years.Every year we ship out big quantity of HDG products.We Warmly welcome your inquiry!

Standards and research on protected cultivation are published by organisations such as the ISHS, and industry practice is covered by trade media such as Produce Grower.

Frequently Asked Questions:

Q: Do you produce the greenhouses yourself, or outsource the production?
A: We are a manufacturer, not a trading company. Ziyang Bozong Greenhouse Industry Co., Ltd has been producing greenhouses in our own factory for over 35 years, with 180,000 square meters of production space and 378 employees.
 
Q: Which countries do you export to?
A: We export to more than 32 countries, including Russia, the UAE, Kuwait, Nicaragua, Canada, Chile, South Africa and Uzbekistan. We ship worldwide.
 
Q: Do you design greenhouses for different weather conditions?
A: Yes. Every greenhouse is designed around the customer’s requirements and the local weather. We adjust the frame, span and covering to suit your site, and our structures are built for high wind resistance.
 
Q: What is hot dip galvanized steel pipe used for?
A: It is used as the structural frame of greenhouses. Hot dip galvanizing forms a metallurgical bond with the steel, so the coating becomes part of the steel surface and protects every section, including cavities, sharp corners and hidden areas.
 
Q: How long does the hot dip galvanized coating last?
A: It depends on the site and the coating thickness. Under ISO 9223 and BS EN ISO 14713-1, clean suburban air (class C2) gives 50 years or more without repair on a standard coating, while urban and coastal air (class C3 to C5) gives roughly 20 to 30 years to first maintenance. Thicker coatings extend that period in proportion, and the zinc layer can be measured before the pipes leave the factory.
