Why Choose Galvanized Steel Pipe for Greenhouse Construction?

Greenhouse skeleton is an indispensable and important part of the construction of greenhouses, the quality of the greenhouse skeleton directly affects the quality of the construction of greenhouses, so when choosing the skeleton of the greenhouse, we should learn to distinguish between the materials, different materials are suitable for different greenhouses.

How about Galvanized Steel Pipe for Greenhouse?

Galvanized steel pipe for greenhouse is to make the molten metal react with the iron substrate to produce an alloy layer, thus combining both the substrate and the coating. Galvanized steel pipe has the advantages of uniform coating, strong adhesion, long service life, etc. Galvanized steel pipe substrate and molten plating solution undergoes a complex physical and chemical reaction to form a corrosion-resistant, structurally compact zinc-iron alloy layer, the alloy layer is fused with the pure zinc layer and the steel pipe substrate, so it has a strong corrosion resistance.

As the production of greenhouse materials, the strength of galvanized steel pipe for greenhouse is very high, strong resistance to wind and snow, long life, corrosion resistance, in fact, these advantages are only part of it, the most important thing is that its cost is very considerable, including its production process, is very simple, the use of galvanised steel pipe as a greenhouse bracket material, slowly replacing the other materials of the skeleton, in our rural planting industry In the development of our rural planting industry, the use of galvanised steel pipe as the support of our greenhouses, the application is very wide, most of the farmers will choose to use galvanised steel pipe as the main material of the greenhouse.

Hot-Dip Galvanising or Cold Galvanising How to choose Galvanized Steel Pipe for Greenhouse?

Hot-dip Galvanised

Hot dip galvanised thick layer, has a uniform coating, zinc layer is thicker, strong adhesion, long service life and other advantages.

Cold Galvanised

Cold galvanised is actually electro-galvanised, with excellent weather resistance and corrosion resistance, anti-slip, can be used for high-strength bolts friction surface corrosion and other advantages. Corrosion resistance is a little worse than hot galvanised pipe.

Performance Characteristics and Differences

Corrosion Resistance

Hot dip galvanised is much better than cold galvanised.

Thickness of Galvanised Layer

Hot-dip galvanised thickness is greater than cold galvanised.

Surface Lubrication

Cold galvanised surface is more lubricated and beautiful than hot galvanised.


Cold galvanising is cheaper, hot-dip galvanising is slightly more expensive.

Plating Surface

Cold galvanising can be plated on one side only, while hot-dip galvanising is fully plated.


Cold galvanising has less adhesion than hot-dip galvanising.

What are the Advantages of Galvanized Steel Pipe Greenhouse Compared with Other Greenhouses?

Galvanized steel pipe greenhouse skeleton is made of several inexpensive common chemicals as raw materials, easy to obtain raw materials, simple production process, with low price, high strength, good water resistance, corrosion resistance and anti-aging characteristics.

The shed has a long service life, due to the use of the latest plastic-plated composite process, the service life can reach 10 - 15 years or more.

The surface of the shed bracket is smooth, will not damage the shed membrane by friction with the shed membrane, does not conduct heat, does not bake the membrane, and the bracket will not be deformed by rapid cold and heat. It prolongs the service life of the trellis membrane.

The middle of the trellis skeleton does not need pillars, which greatly increases the cultivation area, saves labour, and can be mechanically cultivated to increase the working efficiency.

The greenhouse skeleton machine can produce two series of products: hollow and solid, and the height, span, arc and diameter specifications of the skeleton can be adjusted arbitrarily, which can be adjusted to round, oval and rectangular skeleton.

Galvanized steel pipe greenhouse construction cost is low.

It can be recycled and reused, and one third of the investment can be recovered.
