Iron is spread in two forms, cast iron and steel. And by increasing and decreasing its alloys, you can get different types of building iron, each of which has a special use.
“Profile”
Hollow metal sections used in buildings are called profiles. Profiles are available in different shapes such as square and rectangle, and they are also referred to as cans. Profiles are used in staircases, doors and windows, and building fences. There are two types of profiles, open and closed. Closed profiles include pipes, PVC profiles, door and window profiles, etc. Belts, beams, studs, corners, quadrilaterals, etc. are included in the category of open profiles. In addition to building, profiles are also widely used in the automotive industry.
"Beams"
The beam is one of the most basic profiles used in the building. The products of the beams have a cross-sectional area in the shape of H and I and are used in steel structures. The role of the beam in the building is to support the load that enters the building. Different types of iron beams, each of which is used in certain cases. Honeycomb beam, INP beam, IPE beam and wide wing beam are types of beams.
“Metal sheet”
Metal sheets are another type of construction iron, which are available in different types of aluminum sheet, oxide sheet, colored sheet, and hot and cold sheet, and each one is used in a specific type of structure. . Hot sheets are used for structures that require high strength, and cold or oiled sheets are used for structures that have a more important appearance.
“Rebar”
Rebar is one of the most famous building profiles that is used in all buildings. By using rebar, the strength and resistance of concrete structures will increase and we will have a stronger and more durable building. Rebars are also used in the building floor and foundation, and they increase the resistance of concrete during earthquakes. The rebars are available in three categories: ribbed, coiled, and plain.
Ribbed rebars have bumps on their surface and are used in special cases, but simple rebars have a completely smooth and polished surface. Rebars are also divided based on their constituent materials, which exist in 6 different cases, which are: galvanized rebar, epoxy coated rebar, carbon steel rebar, fiberglass limer rebar and stainless steel rebar. The highest resistance for concrete is provided by stainless steel rebar, which has the highest price compared to other rebars."Corner and gutter"
Studs are U-shaped steel sections and are widely used in construction as well as in industry. Stud products are available in different materials such as galvanized, steel and aluminum, and they are also available in the market in two forms, simple and mesh, each of which is designed for specific purposes. Mesh studs have holes in their structure. which are usually used for bolts and nuts in various applications. Studs are produced from hot sheet. Corner is one of the most used types of construction iron, which has two cross-sections perpendicular to each other. The classification is based on the production method of these corners, and the fabric corner comes out of the production line as a two-section corner, but the pressed corner is a 6-meter-long sheet that is bent in the middle. There is also another classification based on the appearance of the angles, which include equal wing angle and unequal wing angle. In the equal wing angle, two wings are of the same size, and in the latter case, the two wings are of different size. The price of the corner and the price of the stud varies according to the fluctuations in the price of iron. And they also depend on the weight of these irons.
“Metal tube”
Pipes are among other types of construction iron that are used in different buildings. Pipe products have circular sections and are used to transport liquids and gases. Pipes are produced in two categories, seamed and seamless. In the process of making seamed pipes, after heating, the sheets pass through special rollers and the edges of the pipe are welded together using different welding methods, as a result of which a seam is created in these pipes. But in seamless pipes, which are also called Manisman pipes, no welding is used. These pipes are without any seams.
