As a rule, each project is judged on its use of structural steel from both an architectural and structural engineering perspective. Over the years, galvanized steel pipe has become one of the most preferred superior construction material widely used in construction field around the world. Most contractors favor choosing structural steel products for structural steel buildings, for it is more cost efficient, dependable, easy to customize and easy to maintain in use.

Galvanized steel pipe generally has the rational cost effective in the market. Compared with other typical steel pipe coatings, such as specialized painting and powder coating, galvanization is much more labor-intensive, resulting in a higher initial cost for contractors. Besides, due to its durability and anti-corrosive properties, galvanized steel pipe can recycled and reused, which to some degree save a lot of money during the post maintenance work. Furthermore, unlike other structural steel pipes in the steel pipe market, galvanized steel pipe is immediately ready for use when it is delivered. No additional preparation of the surface is required, no time-consuming inspections, additional painting or coatings are needed. Once the structure is assembled, contractors can immediately begin the next stage of construction without having to worry about the galvanized steel materials.

Hot dipped galvanized pipe has been considered popular a lot among many users today. For one thing, the galvanization process protects the steel from rusting damage that can occur during transportation, installation and service. The zinc layer on the surface of pipe can form a barrier protection for steel products to extend the service life in applications. For the other thing, this layer is also resistant to wear and scratches, which makes the steel look more attractive. With the layer of protection, pipes can be used in outdoor areas, and can withstand the harm from some of the environmental effects. Galvanized steel pipe is used in many outdoor applications such as fencing, fence posts and water-supply pipes.

As steel is a versatile building material, which has led to its inclusion in nearly every stage of the construction process from framing and floor joists, to roofing materials. Testing and studies have revealed that the average life expectancy for galvanized steel used as a typical structural material is well beyond 50 years in a rural environment and 20-25 years or more in an extreme urban or coastal setting. In that regard, contractors can confidently use this product in project. As a professional steel pipe manufacturer in China, we have a suggestion that if you choose a galvanized pipe, you can avoid the cost of maintaining and replacing corroded pipes.

The most recently released trade data indicates that scrap steel imports by Vietnam during the month of November this year dropped sharply when compared with the previous month.
Vietnam imported 220,000 tons of scrap steel during Nov ‘15. The scrap imports by the country have dropped by nearly 12.8% when compared with the imports during the month before. The scrap imports by the country had totaled 253,000 tons during October this year.

The average import price of scrap steel during the eleventh month of the year 2018 stood at US$187.70 per ton. The average scrap import value dropped considerably by 11.4% when matched with the previous month. The scrap imports by the country had averaged at $211.80 per ton during October this year.
The cumulative scrap imports by the country during the initial eleven months of the year totaled 2.916 million tons. The scrap imports were down by 5.1% when compared with imports during the corresponding eleven-month period in 2017. The Vietnamese scrap imports had totaled 3.073 million tons during January to November last year.
The country’s scrap imports are estimated to total around 3.18 million tons during the entire year 2018.

However, some Chinese steel tube manufacturers have reportedly raised their prices to 5440 yuan/ton, but the market remains skeptical that the increases are an attempt to improve their position in ongoing car negotiations.
This week, Tianjin steel pipe recorded transactions in the range of 4,500 to 4,700 yuan per tonne. Future gains are expected to be modest.
According to statistics released by the China iron and steel association, the country’s steel production fell slightly by 0.8 percent in the week ending June. 19, 2018. In the week leading up to that, production fell 1.1 per cent.
As of June 19 date within a week, the domestic production of the original steel output of 1.523 million net tons. The company, according to data from the production of raw materials in slightly down 0.8% this week. A week before it has to do with (that is, as of December 12 week) compared to the production data of 1.536 million tons. Moreover, the weekly production was significantly reduced by 15.2 per cent compared to the same period of the previous year, compared with a yield of 1795 million net tons.
In the week ending June 19, 2018, capacity utilization rate of structural steel pipe manufacturer decreased to 63.7%.
Capacity utilisation is reduced slightly compared to the previous week (i.e. the one end of December 12). In addition, capacity utilization significantly reduced by 74.6 percent compared to the same period of the previous year.

The overall price of domestic building steel products continues to rise, in which the rise of the spiral steel and wire rod in Beijing and Tianjin is more than 200 yuan/ton; Last week, the downward trend of the board ended, and the board rose again in all directions, reaching three cities with an increase of more than 100 yuan/ton. The cold rolling has gone up a lot, and the hot rolling has been greatly increased when the factory price has been greatly increased, such as Baosteel and Angangsteel. Large and medium – sized material small increase. Analysts expect construction China steel gi pipe prices to rise in general next week.

There’s a lot of hot zinc, more often used to be steel pipes or solar steel, which is going to be hot galvanized, and the performance of the product will be greatly improved, and a lot of people don’t really know about the benefits of hot galvanized, and in fact, many of the products are made with hot zinc.
First of all, the biggest role of hot dip galvanization is to prevent the body from rusting. We all know that no matter what product rusts, it will reduce its life. The rusting corrodes the material itself very quickly. Galvanized, it makes the product more beautiful, not the color of the product that’s not galvanized, it’s not nice, and zinc is silver, so the galvanized product looks cleaner and beautiful.
The unique advantage of China hot dipped galvanized steel pipe is its environmental protection, no pollution, low cost, saving time and energy, and giving people more time, energy and money.
China galvanized steel pipe is a single layer of zinc coated on a narrow and long steel sheet by means of cold rolling or hot-rolling, which is zinc-plated and galvanized, which is more uniform, strong in adhesion, long service life, and which can make galvanized steel pipes corrosion-resistant, and which can be corrosion-resistant, and rust or phenomenon can occur during use, so what is the cause?
The corrosion of the gi square steel pipe is the main reason for the coating surface. The chemical properties of zinc are more active, which can be soluble in both acid and alkali. In humid environment, zinc will react on the surface, forming alkaline zinc carbonate film, and contacting materials with hydrogen sulfide. The zinc resistance will be less corroded, which is easy to corrode, exposing the surface of steel plate and eventually rusting. The corrosion probability of galvanized steel plate is relatively low, because the galvanized layer is thicker, it is not easy to cause the steel plate oxidation, so it is not easy to rust.
Galvanized steel pipes are becoming increasingly popular in some large factories because of the high corrosion resistance of galvanized steel pipes, which we want to describe in more detail in order to save galvanised life.
The corrosion resistance of hot dipped galvanized square steel tube has entered into people’s concept, so the anti-corrosion treatment of galvanized steel pipe is not paid much attention to by people, and the anti-corrosion ability of galvanized steel pipe can be easily enhanced, which is largely ignored.
Galvanized steel pipes are used on the ground, sometimes with mud. The traditional concept is that galvanized steel pipes will no longer work in this case. This concept is actually an oversight of the use of galvanized steel pipes. Because zinc itself can oxidize, but it’s slower than iron. However, if galvanized steel pipe is treated with corrosion, it can be more beneficial to the life of galvanized steel pipe. The antiseptic treatment for underground use is to coat the steel exterior with epoxy coal tar asphalt, adhesive tape and other coatings.
In fact, these seemingly simple methods can be applied to the protection of galvanized steel pipes commonly used, and can be handled before they are put into use, so as to reduce the tedious construction trouble in the construction process.

There are lots of materials we can use for construction foundation, such as timber piles, concrete piles and steel piles. What’s the difference between them? And finally which one would be better for us? According to the ratio of using spiral welded pipe, Sara thinks that steel products have their special advantages

First, timber piles is different from concrete or steel piles as they are naturally made instead of man-made. This means they are cheaper than concrete or steel piles. Because of thenatural characteristics of timber, the density or unit weight of timber piles is variable and highly dependent on the species, specific gravity and water content of the timber itself. Under this situation, we cannot make sure the quality when they face with the hurricane which is its shortage. Of course, it is very easy of corrosion and rust which has not long life service.
What’s more, concrete piles are both similar and different to timber piles and to steel piles. Concrete and timber piles are considered “displacement” piles. Actually, we all know that concrete piles are expensive than timber piles. However, the cost would be higher than timber piles.
Finally, steel piles made by steel would have its special advantages for human. Steel piles slide past soil particles as they are being driven instead of displacing them. Due to this corrosion resistant, steel piles can be made into any reasonable lengths since splicing is usually not an issue. Of course, they can withstand hard driving situations but unlike concrete piles are not subject to a wave, so this is the main reason to use it like other hot rolled steel pipe such as seamless steel pipe, spiral steel pipe and ERW steel pipe?
What I want to say is that when we see this building, it looks beautiful. The appearance of beautiful, of course, also including the shape of the various kinds of steel pipe, such as ERW steel pipe, spiral welded pipe, used for water, oil and gas transportation.
No matter which kind of steel pipe you choose as your project. Poor quality steel pipes will be kicked out of the group. So, how do we figure out what we need to do with precision engineering or to estimate housing? Comparison will be our first choice.
Straight seam high frequency welded pipe is welded by welding and induction welding, divided into two forms: hot rolling and cold rolling. Hot rolled coils are used as raw materials, and other processes, such as continuous forming, welding, heat treatment, sizing, straightening, etc., there is no doubt that ERW steel pipe used for low pressure liquid delivery, such as water, gas, oil, etc.
Spiral welded pipe has the characteristics of short, high dimensional precision, uniform thickness, surface quality and so on, and has higher pressure than cold galvanized steel pipe china . Therefore, when we encounter this situation, we can select the helical welded pipe of the high-pressure engineering project instead of the ERW steel pipe.
