Corner

The corner, also known as the L bracket or angled iron, is a metal bracket with a suitable angle. The corner is made of galvanized metal and is often used in masonry or applied by welding or drilling on various surfaces.Angle rods are often used to support beams and other structural systems, but their performance goes beyond their usual role. Angle rods can provide greater strength, protect structures from corrosion, and provide even greater stability.

What is a corner?

A profile with a cross section of two perpendicular sides is called a corner, which is used in different structures. This section is one of the most important building materials and profiles that are used in composite and single form in civil, construction and industrial projects. In addition, the corner can be used in combination with other devices and structures.The corner is shown in construction drawings with the English letter L "L" and if the wing is equal, the letter size is inserted after the letter L. For example, L200 means wing angles equal to the size of the wing 200 mm and if the wings are unequal, the size Both wings are inserted side by side in multiplication, like L200 * 100, ie the angle of the unequal wing, one wing of which is 200 mm and one wing of which is 100 mm.

Corner benefits
Strong support for structures

Large angular bars support the columns and beams structurally and provide greater strength and stability. They also provide vertical and horizontal support for buildings, including towers and distribution equipment. Because angle bars are made of galvanized steel, they are more resistant to corrosion and other weather effects.
Strengthen edges and corners

Angle bars can also cover edges and corners. The corner helps the structure stay in shape and prevent normal weathering wear. Sharp corners and edges reinforced with angular rods can be more durable and resistant to chips and corrosion. They also provide extra strength and make each corner more stable.

Ready-made frames and shelving units

Smaller angle bars support bed frames, tables and benches. They are also used as a stand for wall-mounted shelves. They provide full support when loading shelves with heavy equipment. However, in terms of industrial appearance, angle bars are suitable for storing shelves in areas such as garages and workshop rooms.

Corner applications

It is used to connect bridges to columns or to connect beams to load-bearing beams and to connect columns to slabs in the foundation. A corner can also be used to build a truss pillar. Corners with dimensions of 50 to 150 mm are used for all the purposes mentioned above. Therefore, these are some of the corner applications. These products are used in different applications in the form of branches and bites. Among the applications of this product, the following can be mentioned:

Products with a size of 50 to 150 mm are used to connect bridges to columns, beams to load-bearing beams, columns to slabs in the foundation.
Construction of columns and trusses
Use in structures related to elevators
Use of corner beams in kermit roofs
Use for simple connections in structures
Use in bracing and LSF structures
Power transmission tower
Industrial Machinery
Restraining clay walls
To prevent the fall or fall of the clay walls of the reinforced concrete or steel building, the walls without facades and symbolic walls should be properly angled.

Types of corners in terms of type of production
In terms of type of production, they are divided into two types:
1. Corner press

This type is made of a sheet with a length of 6 meters that is bent in the middle of the width of the sheet and is shaped into it, which means that the basic nature of this type of corner is a sheet of steel sheet.

2. Fabric angle

This type leaves the production line at the beginning of the production process in the form of a corner.

Types of corners in appearance

Corners are divided into two types in terms of appearance:
1.Equal wings
2. Uneven wings

1.ball equal

Corner is shown in construction drawings with the English letter L (L) and if the wing is equal, the letter size is inserted after the letter L. For example, L200 means wing angles equal to the size of the wing 200 mm.

2. Uneven wings
In this regard, unequal angles are among the sections that are used in special industries that for any reason, it is not possible to use common angles or so-called equal (L) and the only solution is to use unequal angles. . Uneven corners are available in different dimensions and thicknesses, and with different materials including; ST52, ST37 and ST44 are produced and supplied. If the wings are unequal, in the size map, both wings are multiplied side by side, such as L200 * 100, meaning that one wing is 200 mm and one wing is 100 mm.

Famous corner models
Spiral corner

It is a kind of equal wing angle that is produced by hot climbing method and because it has high flexibility, operations such as welding and drilling can be easily performed on them.

Steel corner

This type, like a steel corner, is produced in two forms: fabric and press. There are some places that have high humidity, if they use steel corners in these environments, it will rust and corrode after a short time; For this reason, in these environments, they go for steel corners.

304 alloy steel corners are low in carbon and 304 stainless steels are used to make this type. The surface of these corners is smooth. Application of this type of steel is commonly used in the construction of frames, tanks, cabinets and enclosures and their most applications are in marine, chemical and petrochemical industries. In it. They are used in the production of shelves and building structures and because they do not rust in acidic environments, it is widely used in marine structures and submarines.

Steel tile corner

Sometimes the columns are tiled around the corner of the tile. This not only prevents the tile from filling up, but also gives it a special beauty. Therefore, in general, when a steel corner is used to protect the facade and stone, it is called a steel corner of a tile. A perforated steel corner has holes of different sizes in the shape of an oval and a circle. Its applications include its use on shelves, garage door openers and equipment stands.

Aluminum corner

They are made of aluminum and are usually produced in the dimensions of 50 to 150 mm, including their use can be used in connections between stairs with columns or connections between load-bearing and beams. The most important features of these are as follows:

low weight
High resistance to corrosion and various weather conditions.
They are non-magnetic, which is why they are used in rigs.
They have a unique beauty, which is why they are widely used in interior and exterior decoration.
Drilling, cutting and welding are easy on them.

PVC corner

PVC type and folding This type of profile is both for use in 90 degree angles as a surface and decorative. This product is not made of steel, so it is light in weight and is often used in busy places such as corridors and lobbies.

Galvanized corner

Zinc galvanized corner is the steel on which the galvanizing operation has been performed. Zinc metal is used to perform the galvanizing process.

The corner of the bite

In some structures, such as elevators, chopped corners are used, which is called a bite corner.
Plastic corner

Polyethylene plastic is used in different sizes and dimensions for applications such as fruit packaging, stone industry, ceramic tiles and metal sheets. This product is one of the most suitable products to protect the sharp edges of goods in their packaging and transportation.

standards

The standards of this product in different countries are as follows

GOST 8510
DIN EN 10056-1
GOST 8240
ASME S1-36

how to calculate weight

The weight of the product is in kilograms and you can use the following formula to calculate it:

Thickness (meters) × Length (meters) × Wing size (meters) × 7850 × 2 = Product weight (kg)
