China hollow section tubes are popular in structure applications today

As we all know, the excellent properties of the tubular shape have been recognized for a long time. In the first part of the previous century, an Englishman, Whitehouse, developed the fire welding of circular hollow sections. However, the production of welded circular hollow sections became more important after the development of the continuous welding process in 1930 by the American, Fretz Moon. In the recent years, the first production methods for seamless and welded steel pipe have made great progress in the steel pipe industry.

Technically speaking, design is an interactive process between the functional and architectural requirements and the strength and fabrication aspects. In a good design, all these aspects have to be considered in a balanced way. Due to the special features of hollow sections and their joints, it seems even of more importance than for steel structures of open sections. Therefore, it is very important for you to choose the proper type of structural steel pipe in construction projects. In these years, China hollow section tubes play a significant role in the global steel pipe market. China hollow section tubes as an important building material used in the construction industry tend to serve a wide range of functions often, due to the good performances of durability, strength and resistance to harsh environment conditions. In the current steel pipe market, round steel pipe and square steel pipe are the popular building materials in construction. With steel, it's easy to expose the building's beauty in a design that will emphasize its grace, strength, transparency, and slenderness. The column-free clear spans and the use of colored steel pipe coatings bring out the natural lighting of the frame and its simple elegance. In construction projects, China hollow section tubes have many uses such as structural applications involved in residential, commercial and industrial construction. In particulars, as the flat square surface has the performance to ease construction, rectangular steel pipes are sometimes widely used for architectural aesthetics in exposed structures.

In the current steel pipe market, hot dipped galvanized steel pipe are very popular among builders. Many examples in nature show the excellent properties of the tubular shape with regard to loading in compression, torsion and bending in all directions. And these excellent properties are combined with an attractive shape for architectural applications. Furthermore, the closed shape without sharp corners reduces the area to be protected and extends the corrosion protection life in applications.

How to choose the proper type of galvanized steel pipe in your project

Technically speaking, galvanized steel pipe is a type of steel pipe that has been coated with zinc. This coating protects the steel from corrosion. It is most commonly used for outdoor construction like fences and handrails, or for some interior plumbing. It is also sometimes called galvanized iron pipe.

China hollow section tubes are very popular among users today. Seamless pipe and welded pipe are two common type of hollow structural section in use. Tianjin gi square steel pipe is used widely as 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 in the society. Because of years of production and processing experience, today's Tianjin gi square steel pipe production technology has got more improved and matured. Besides, with the complete steel pipe production equipment, as well as the professional and experienced personnel, Tianjin steel pipe production is committed to meeting the customer's various practical application needs.

Hot dipped galvanized steel 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 scratch, which makes the steel look more attractive. As a rule, with different processing technology, there will be different product costs. That can be clearly reflected in the different pipe pricing of the two kinds of pipes. Due to the high costs, hot dipped galvanized steel pipe price is more expensive than other common types of steel pipes in the current steel pipe market.

Pre galvanized steel pipe is another popular type of galvanized steel pipe in the market today, which was galvanized while in sheet format, thus prior to further manufacturing. Pre-galvanization is also known as mill galvanized, due to the fact that the steel sheet is rolled through molten zinc. After the sheet is sent through the mill to be galvanized it is cut to size and recoiled. A specific thickness is applied to the entire sheet, for example pre-galvanized Z275 steel has a 275g per square meter zinc coating. One of the advantages which pre-galvanized steel has over hot dip galvanized steel is that it has a better appearance.

How to look at galvanized steel pipe used for frame scaffolding

Generally speaking, frame scaffolding is one of the most common types of scaffolding, often seen on construction sites worldwide. Typically the frame scaffolding is manufactured from round steel tube, available in several different configurations, from a section that contains both a ladder and a walk-through portal to sections that are totally walk-through and sections that resemble a ladder. The typical method of constructing frame scaffolding is to use two sections of the scaffold frame connected by two crossed sections of support poles arranged in a square configuration.

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. If you choose a galvanized pipe, you can avoid the cost of maintaining and replacing corroded pipes. With galvanized pipe, your pipes can last a lot longer than a non galvanized one, which will save you a lot of money in the project.

Unlike other structural steel materials, galvanized steel 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. In the majority of cases, China hollow section tube are widely used for frame scaffolding is in good condition and erected properly, it will provide a stable elevated work platform at virtually any height so that workers can easily and safely work anytime.

Today, there are many different types of scaffolding in construction. 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. Hot dipped galvanized pipe has been considered popular a lot among many users today. With the layer of protection, this kind of steel pipes can be used in outdoor areas, and can withstand the harm from some of the environmental effects, which are especially used in construction today.

Why to choose galvanized steel tube as building material in construction?

Due to the great strength, uniformity, light weight, ease of use, and many other desirable properties, galvanized steel pipe has been widely used in a variety of practical purposes. At present, more and more building owners, designers, architects, and general contractors have opted for galvanized in commercial construction projects over other materials mainly for its energy efficiency, low maintenance, and durability. Besides, some other key attributes, such as striking beauty, clean look, and versatility in both new and retrofit construction are becoming helpful to firmly establish steel as the material of choice for institutional, commercial and education building projects.

Compared to timber framing, the initial construction cost is typically more expensive. For builders, you’ll find it cheaper to choose galvanized steel pipe for building materials in construction because it is recyclable, which means that waste removal companies often don’t charge to pick up your scrap steel. For the homeowner, the money savings come with things like maintenance and insurance. Steel frames won’t rot, splinter or become damaged by pests, and insurance companies typically charge substantially less on homeowner’s insurance for steel frames over timber frames. Hot dipped galvanized steel 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.

How to prevent galvanized steel pipe in use from white rust

Galvanized steel pipe generally has the rational cost effective in the current steel pipe market. White rust is a post-galvanizing phenomenon. Responsibility for its prevention lies in the manner it is packed, handled and stored prior to the galvanised product’s installation and use. The presence of white rust is not a reflection on the galvanised coating's performance, but rather the responsibility of all those involved in the supply chain to ensure that the causes of white rust are recognised and the risks of its occurrence minimized on newly galvanised steel.

Hot dipped galvanized steel pipe has the good corrosion properties of zinc, due to a thin film of corrosion product that forms on the surface of the metal. This tightly-adherent corrosion film is called a passivation layer. The formation of the passivation layer is essential to achieving longlife with a galvanized product. Zinc will naturally form a passivation layer when exposed to weathering over an extended period of time. Rain combined with air dryingwill, over the course of a year or more form a passivation layer on all areas of the zinc which do not come in contact with recirculating water. Thus, the exterior of evaporative equipment and all interior areas above the drift eliminators will naturally develop a passivation film. Furthermore, where white rusting has occurred and the item may be subject to continuing exposure that may propagate similar corrosion, re-passivating of the surface can be done by treating the surface with a solution of 5% sodium dichromate 0.1% sulphuric acid, brushing with a stiff wire brush for 30 seconds before thorough rinsing of the surface.

As a professional steel pipe manufacturer in China, we know that white rust may sometimes be interchanged with the term wet storage staining since they have a similar corrosion mechanism. Wet storage staining is typically a pre-construction problem where new galvanized steel sheet or parts are exposed to a wet or moist environment because of improper storage. Post-construction white rust is a problem where the fresh galvanized surface is not able to form a protective, non-porous basic zinc oxide and typically the surface is partially wetted or completely submerged in water. In both cases, the deterioration begins when a localized corrosion cell is formed. The activity of such a corrosion cell/pit, results in rapid penetration through the zinc coating to the steel.

Today, galvanized steel pipe is one common type of structural steel pipe widely used in construction. With newly galvanised steelwork, the zinc's surface has been subjected to little oxidation and is at its most vulnerable. For this reason, a chromate passivation should be used in conjunction galvanizing operations to provide protection to the galvanised coating during the ‘youth’ period of the coating. This passivation coating provides short term protection to the zinc to give the stable oxides time to form on the surface.

Galvanized steel pipe applications in life

Galvanized steel pipe has the benefit of being the most versatile pipe material available today. There are many different uses for galvanized steel in a number of industries. It can be configured with various joint types, and can be fabricated into elbows of any angle, reducers, wyes, crosses, and tees. 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.

As we all know, steel pipe price is comparatively high compared with that of other common materials in use, but they are the strongest and most durable of all water supply pipes. They can withstand high water pressure, come in convenient (longer) lengths than most other pipes and thus incur lower installation/transportation costs. Today, galvanized steel pipe is also used for many other liquid transport applications, such as for energy distribution at power plants and for the oil industry. It has also become an important part of wind energy, as thousands of steel towers are installed to supports the wind turbines. In addition, galvanized steel pipe is used to transport a potpourri of fluids long distances, and with the application of any number of high-quality coatings, is adaptable through all types of soil environments as well as exposed piping systems.

In construction field, galvanized steel pipe is widely used for frame building materials. They are made into different shapes, including round, square or rectangular steel tubes. They are also manufactured in different lengths and thicknesses depending on what their use will be for. In addition to steel tubes, other steel products used in construction might be steel bars or plates. These materials are not always a straight bar either and they can be bent based on specific purposes in use. Unlike other structural steel materials, galvanized steel 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.

Galvanized steel pipe can be frequently used for steel conduit in wire system to provide a very good protection to enclosed conductors from impact, moisture, and chemical vapors. Varying numbers, sizes, and types of conductors can be pulled into a conduit, which simplifies design and construction compared to multiple runs of cables or the expense of customized composite cable. Wiring systems in buildings may be subject to frequent alterations. Frequent wiring changes are made simpler and safer through the use of electrical conduit, as existing conductors can be withdrawn and new conductors installed, with little disruption along the path of the conduit.
