Two columns may be too far apart in some structures, such as sheds, so the structure may not be very strong. For this purpose, C-Purlin is used to connect the columns to each other.
Profile C or C purlin is actually a horizontal beam that designed in the shape of an English letter “C”. The geometry of this product is such that it is very suitable for screwing. To get more familiar with this steel product, we will first explain about the profile itself.
What is Profile?
Profiles are steel products that have a hollow cross section with a certain length. Due to excellent design and mechanical properties, profiles have different construction and industrial applications. These products are very diverse in terms of dimensions and shape and therefore are not limited to a specific project.
Different Types of Profile
Profiles are divided into open and closed types in terms of cross section design, and profile C is one of the open profiles. Open profiles are as following:
• Equal Angle Formed
• Gutter
• Iron Beam
• Profile C
• Metal Door Frame
• Highway Guardrail
• Steel Flat Bar
• Beam
• Metal/Steel Door Frame
In contrast, there are closed profiles that are closed in terms of cross section design, such as construction hollow-sections (square or rectangular), steel pipes and PVC profiles. These sections are mostly used in construction, but they also have industrial applications.
Purlin C Application
As explained before, Purlin C is mostly used for the strength of structural sections, especially columns. The position of this section is such that it distributes the load of the building and reduces the pressure on the column. But this purlin is not only used to build the roof. This product is also used in the following cases:
*Non-Load-Bearing Wall Construction: The wall is the most important part of the building; which task is to separate the spaces of a structure such as a room. This purlin is used to build non-load-bearing walls. Non-load-bearing walls are walls that can only support their own weight, not the weight of the upper floors of the building.
*Warehouse Construction: In many and various warehouses construction, C-Purlin is used due to its easy installation.
*Steel Structure Construction: The shape of this purlin allows it to be screwed. Using this purlin speeds up the construction of steel structures, which saves on project costs.
*Semi-floor Construction: Semi-floor and Mezzanine flooring is a space that is placed between the ceiling and the flooring and is more like a platform. This structure is made by bolting several columns with C-Purlin and is used in factories, sheds and even residential houses. So the usage of C-Purlin in this structure is very good because t increases its strength.
Sheet Used in C Purlin Production
To produce the C purlin, you can use the galvanized sheet because it is very resistant to corrosion. This sheet is not only stainless but also resistant to severe shocks. Therefore, it increases the strength of the structure.
Advantages of C Purlin Application
The use of this purlin is very common due to its excellent features such as high tensile strength and light weight. But this is only one of the advantages of this product. Other advantages of this product are as follow:
*Easy Installation: C purlin is used in most industrial structures; such as sheds or grain storage which require screwing to build faster. Purlin C is designed so that it can be easily attached to the roof columns using bolts.
*Reduce Transportation Costs: Since the weight of this product is lighter than heavy purlins such as beam, it can be loaded in a larger volume and thus saves shipping and transportation costs.
*High Durability: Because this product is produced by galvanized sheet, it is very resistant to humidity and corrosion, so it lasts for years.
*Fireproof: To build large structures such as sheds, much costs including labor and materials. In the event of a fire, the structure may collapse. Purlin C is fireproof due to its galvanized coating.
* Recyclable: Because this profile is made of steel, even scrap is used. After demolition of the building, C purlin can be re-collected as iron scrap and re-melted in the furnace.
Dimension of C-Purlin
In the iron market, there are different sizes of this purlin which vary depending on its application. But according to the standard, the length of this purlin is 6 m. and its height is between 160 and 240 mm. Of course, this product can be produced in desired dimensions according to the customer’s order.
Manufacturing Method of C Purlin
C purlin is usually manufactured by cold-rolled method. In this method, first the galvanized coils are opened by the decoiler. Then they are turned into sheet and cut to the desired size. After the sheet is cut, it enters the roll forming machine and after passing through the rollers, it is changed to the desired shape.
Sarir Sanat Amir Company is one of the largest manufacturers of C Purlin (Profile C) in Iran, which produces and supplies C purlin with thicknesses of 2, 2.5 and 3 mm.. Also this company produces C Purlin with various lengths according to the customers’ orders.
Factors that Impact the Steel Price
There are many different factors that affect the price of C Purlin (Profile C). In our country, because the iron market fluctuates a lot, the price of this purlin is very affected. Profile C is one of the important factors in the construction chain. Therefore, it acts as a link between the economic and industrial spheres. So inevitably any factor involved in these areas will definitely affect the price of this product. The factors that affect the price of the purlin are as follows:
*Currency Fluctuations: Fluctuations that occur in the field of currency, will increase the price of raw materials of purlin C. Because some raw materials may be imported through the export. Hence, the final price of the profile is strongly influenced by the currency fluctuations, especially the dollar.
*Difference in Manufacturing Method: Manufacturing method can be affected the price of this product. The better this product is manufactured; the higher quality will be seen. As a result, its price rises in the market. Sometimes this purlin is not rolled properly or its edges are not bent properly. As a result, customer dissatisfaction has followed.
*Price of Galvanized Sheet: As mentioned before, galvanized sheet is the main steel sheet for the production of this product. So with the increase in the price of galvanized sheet, the price of this purlin will also increase.
* Iron Ore Production Amount: Iron ore is one of the raw material for steel production. Therefore, steel, which is very important as a main industry in our country, is highly dependent on the amount of iron ore mining. The lower the supply and distribution of iron ore, the higher the demand for steel products such as C purlin. As a result, as demand increases, so does its price.
* Iron Scrap Prices: Iron scrap is one of the raw material for the steel sections manufacturing. Therefore, any change in the price of this product can increase or decrease the price of C purlin.
*Fuel Price: The steel industry is closely linked to transportation and fuel. Because when C purlin is loaded at high tonnages, it requires trailers, trucks and even ships. These vehicles consume a lot of fuel. Therefore, the higher the price of fuel, the higher the shipping and transportation costs. In this case, the price of C purlin will also increase.
The Last Word
C purlin or profile C is one of the important elements in the building construction and types of sheds. This profile, which is one of the open profiles, is easy to install, suitable weight and high durability. Factors such as iron ore price, fuel price, iron ore production, iron scrap and production method affect the price of this product. Sarir Sanat Amir Company is a manufacturer of C purlin and profiles with different dimensions by using experienced and technical personnel. If you find any questions about this product, please do not hesitate to contact the experts of Sarir Sanat Amir Company.
