A corner is a type of profile that is made in the form of two perpendicular sides. This profile plays a very important role in the construction industry. In fact, corners are used for different parts of the building like beams, rebars and studs. Everyone knows this product with the thickness and size of the wings. In the future, stay with Damir Nab to introduce the corner, its types and its uses.
One of the most widely used profiles used for building construction is the corner. This metal piece is made by joining two different surfaces together. Of course, the application of this product is not only for the construction industry, but it is also used in other industries. You can identify corners by their edges. This product has two sides of equal size and 90 degree angle.
The angular shape and appearance is just like the English letter L. Its weight and thickness are also different in different products. That is why the corner price is not the same.
These delicate profiles are used to make all kinds of column foundations, stairs, mast construction, trusses, fences, door and window frames, light roofs and gables. Also, in some cases, an angle is used to connect the beam and column, to build the backing and restrain the lateral force between the columns in metal structures.
Considering that the corner has different types in terms of production method and appearance, its application is also different. The most important application of this delicate profile is for building. Of course, in the construction of LSF structures, power towers, trusses, windbreaks and all kinds of metal frames are also used.
Nowadays, corners are widely used in industries such as industrial equipment and machinery. Engineers and experts determine its use according to the type of angle. For example, to connect bridges to columns in metal structures, a corner with a size of 50 to 150 mm is used. These products are also used for connecting beams to load-bearing beams and connecting columns to plates in building construction. Another example is crushed corners or bite corners, which are used to make the elevator structure.
For the construction of kermit roofs, they use a corner that places it inside the concrete. Simple connections such as corner connection, connection with sitting corner, semi-clamping connection and girder connection also use corner.
In general, the application of an angle is:
If we are going to categorize the corners in terms of the production method, they are divided into two types: press and fabric. Each of these products has its own characteristics, which include:
To produce Percy corner, they use steel sheets with a length of 6 meters that are bent from the middle of the width. Then they are shaped to turn from sheet steel into angles. This is done by pressing and cold rolling profile. In this way, it first cuts the desired steel sheet. Then he uses a roll forming machine to shape it.
This device bends the sheet with high power, after which it assumes an angular shape.
The roll forming machine is made with several gearboxes that can form steel sheets of any length and thickness. Percy corners can be recognized by their rounded corners.
Another type of corner available in the market is produced by hot rolling method. The production method of this product is different from the press type and their use is also different from each other. This corner is prepared using a bloom or a steel billet. Then it is placed in the furnace with the predetermined size.
Finally, as the fabric corner is heated and flexible, rollers are placed on it to turn the steel billet into a corner profile.
The production method of the fabric corner is hot rolling. In general, it can be said that each of these corners have fundamental differences based on production performance.
Another method used to categorize corners is to pay attention to their appearance. These products are divided into two types of equal wings and unequal wings. But the specifications of each of these corners are:
As it is clear from the name of this product, it has equal wings. In general, the corner product is represented by the English letter L. Now, if the number 200 is seen next to the letter L, it means the same wing angle (for example, L200).
These products are used for the corners of a structure. Of course, the application of the equal wing angle is not only for the construction industry, it is also used in shipbuilding, railways and all kinds of machinery.
These products can be produced in several different sizes. For example, the sizes 20*20*2 to 50*50*5 are known as light corners, which are also called spiral corners. Hot rolling method is used to produce equal wing angle. In this way, first they soften the corner steel sheet with high heat and then shape it.
Another type of corners available in the market have uneven wings. These products are used in various industries. Their application is when an equal wing angle cannot be used and at the same time they need an angle. This product is produced in different sizes and thicknesses.
To recognize the uneven wing angle, you should look at the numbers next to the letter L. Since the wings of this product are not equal, two numbers appear next to L. For example, if you see the expression L200*100 on the corner, it means the corner of an unequal wing, one wing of which is 200 mm and the other wing is 100 mm.
This product is used for residential and non-residential engineering structures. For example, uneven wing angle is used in transportation system, industrial machines, mining infrastructure, power towers, etc.
Another common criterion for classifying corner types in the market is to pay attention to their material and alloy. Therefore, the types of angles can be named as follows:
As their name suggests, aluminum alloy is used for their production. Their production is also done by extrusion method and using a mold. These products go to the market with three quality levels:
These products are produced with various features. In fact, you cannot find an aluminum corner with only one feature in the market. Resistance to iron rust, drilling and welding capability, lightness, etc. are among the different features of aluminum corners. These features also make their use different.
Another type of corners available in the market are galvanized or coated. Iron and zinc metal are used to produce these products. Then they use an electrochemical cell layer to increase the corner resistance. This is done to prevent the corner from oxidizing against moisture and air.
Galvanized corners are used for places that are directly exposed to moisture.
Another type of corners available in the market are made of steel. Steel corner is made using stainless steel billet. This product can be produced by pressing and fabric. To produce a steel press angle by bending the sheet and using a roll forming machine, it is made into an English L or V shape.
The steel fabric angle also first heats the steel sheet to make it into an angle by hot or cold rolling. This product is used just like a galvanized corner for places that deal with moisture. The price of steel corners is higher than the steel and galvanized type.
The price of the corner is determined according to the material it is made of, just like products such as rebar and gutter or beam. A corner is a product that is affected by exchange rate fluctuations. On the other hand, the quality of raw materials also affects the corner price. Among other things that are effective in determining the corner price, we can mention the production method, the type of manufacturing standards, and even the weight and dimensions.
In general, the corner price is changing like other construction materials.
