Tianjin hollow section tubes are widely used in plastic greenhouse projects today
As a light steel structure, plastic greenhouse is lighter in weight, shorter in service life, lower in cost, more sensitive to wind and snow load and less social effect than the industrial and civil building structures, such as masonry, reinforced concrete structures and even other light steel structures. Notable differences in features and characteristics between both structure designs are mainly as the follows. First, plastic greenhouse uses a flexible covering material (such as plastic film) which is far less intensive but more sensitive to the distribution and value of the wind and snow load. Its live load effect is much greater than the permanent load effect; therefore the design parameters (such as statistical parameters of resisting force and load effect ratio) of such structure are different from building structure. Second, greenhouse parts can be removed, transported and reassembled, so the defects in bars and nodes inevitably occur, which has a greater impact on the structure tension performance. Third, greenhouse is relatively short in service life, almost 5-10 years. Forth, due to fewer operators and flexible covering material, the social effects of failure for the plastic greenhouse are far less than the industrial and civil building structures. Therefore, according to the characteristics of the greenhouse above, it seems very critical for you to choose the proper types of steel structures before you would like to start your project in the coming days.
In the global steel pipe market, China hollow section tubes play an active role for many years today. Especially Tianjin hollow section tubes have excellent quality assurance as well as a relatively complete range of specifications, which can basically meet the needs of all walks of life for the practical purposes. Adhering to high quality and environmental products for the first principle, Tianjin hollow section tubes have very good credibility in the steel industry. In that regard, it would be a better choice for you to purchase Tianjin hollow section tubes used in your plastic greenhouse projects. For example, Tianjin galvanized steel pipe generally has the rational cost effective performance in plastic greenhouse applications. Specifically speaking, with its durability and anti-corrosive properties, galvanized steel pipe can be recycled and be reused in your plastic greenhouses, which to some degree save a lot of money during the post maintenance work. Besides, 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 current steel pipe market, Tianjin hollow section tubes are available in many forms for intended purposes, which can be adapted to many shapes and sizes in use. In recent years, Tianjin hollow section tubes have been widely used as structural materials in some large commercial plastic greenhouse projects. For example, considering that the flat square surface has the performance to ease construction, rectangular steel pipes are sometimes widely used for architectural aesthetics in exposed structures in plastic greenhouses today.
