Building hardware refers to steel structures that are used directly and indirectly for building construction. Building irons are produced and used in various shapes, sizes and types according to their use.
Types of Irons
With the recognition of iron and in order to eliminate defects such as its brittleness in its pure state, other elements were gradually added to it and iron alloys were created. Therefore, iron was developed in two forms, steel and cast iron, and today the share of steel in various industries is over 90%. In the meantime, different forms of iron have been able to respond to various applications.
Profile or Cans
Hollow metal cross-section profile in different shapes, which has many applications in various industries, including construction; So that the biggest customers of this product are builders. Square or rectangular cross-section are two common types of profiles, which are also known as cans in the market.
beams
The iron beam has a cross-section in two shapes, I and H, which is widely used in building construction, so that the skeleton of steel structures will not exist without this product. The main task of the beam is to bear the load on the building.
rebar
Rebar is a product with a round and solid cross-section and is considered one of the most famous profiles. This product is used in different parts of the building including foundation, reinforced concrete and columns. In terms of appearance, it is divided into two categories: ribbed and simple, the simple type has a smooth and polished surface, while the ribbed type has protrusions on its body.
sheet
Sheet is divided into 4 types of auxin sheet, colored and ribbed aluminum sheet, cold and hot sheet. Each of the different types of this product have different applications that are used in different structures. For example, cold or oily sheet is used for structures whose appearance is of great importance, while hot sheet is used in structures whose resistance is a high priority, such as tanks.
1) Black Sheet
This type of steel sheets, which are also known as hot rolled sheets, are rolled at a high temperature to reduce their thickness. Due to its lower quality than cold sheet, black sheet is mostly used in non-construction cases to produce industrial products.
2) Cold Sheet
This type of building iron is drawn under the cold method and through cold rolling machines. These sheets are widely used in construction because of their higher quality surface compared to warm sheets.
3) Galvanized Sheet
Galvanized sheet has a zinc coating that is highly resistant to rust, decay and corrosion.
corner
An angle with a cross-sectional area consisting of two sides that are placed next to each other at a certain angle. This product is available in the market in two types, equal wings and unequal wings. A stud is also considered a type of open profile, which is geometrically similar to an English U. This product also has different types that have different prices depending on the intended use.
tube
The pipe is a product with a circular cross-section, which, in addition to the metal type, is also produced in non-metallic types and has various uses; But it is usually used to transfer liquids. It should be noted that the metal type of pipe is divided into two groups, seamed and seamless, and is usually made of iron and copper.
Iron applications
Types of construction iron, each according to their characteristics, can be used for different applications. Due to its high strength and resistance compared to other metals, iron has wide applications. In addition to construction, iron can be used in many industries such as automobiles, household appliances, agricultural equipment, etc. The price of iron per kilo in the market is determined based on the use of this product; Therefore, you should pay enough attention to this issue at the time of purchase.
