Steel beam Steel I-beams are among the most important steel products and are widely used in construction and industrial projects. With their long section and high strength, they are used in structural design to carry loads. In fact, I-beams are used in building frames and play a key role in the structural resistance of a project. This product is manufactured in various types and sizes, each designed for specific applications. An I-beam has two main parts: the central web and the flanges on either sideTypes of I-BeamsBased on their standards, I-beams are classified into different types:IPE I-beam:This type of beam is manufactured in accordance with European and Iranian standards and is produced in an I-shaped cross-section. The flanges of this I-beam have a constant, uniform thickness along the entire length of the product. I-section(IPB):This type has two wide, broad flanges and is produced in two versions: light and heavy. The heavy type is designated with the letter L, and the light type with the letter V. Medium-flange(INP) :This type is manufactured in accordance with Russian and Chinese standards and is produced using the hot-rolling process. The beam has an I-shaped profile, and the flange thickness decreases as it extends away from the web. In terms of application and shape, I-beams can also be classified as follows:Wide-flange (H-shaped) Abbreviation: IPE European standard: Standard I-beam Castellated beam: Features openings in the web Light I-beam A light H-beam is a type of open steel section that has two wide flanges and a central web. Heavy I-beam The heavy H-beam is the heaviest type of beam and offers very high strength and durability. مطالعه
Cold-Rolled (Oily) Sheet Cold-Rolled (Oily) Sheet Cold-rolled (oily) sheet is produced through the cold rolling process and is named for its bright and shiny surface appearance. After the rolling process, the sheet is oiled to increase its resistance to corrosion and rust. Cold-rolled sheets are typically manufactured in thicknesses ranging from 0.3 to 3 mm and in standard widths of 100 to 125 mm. Applications of Cold-Rolled SheetCold-rolled sheets are used in various industries , with the most common applications including:Base material for the production of galvanized sheetsHousehold appliances such as gas stovesCoating and casing of products such as refrigerator panelsPipe manufacturing مطالعه
Color-Coated Sheet color-coated steel sheet Pre-painted steel sheet is essentially galvanized steel sheet coated with an electrostatic paint layer. These sheets are available in approximately 15 different colors in the market. The coating thickness on the top surface of the steel is typically about 20 to 25 microns, while the backside coating thickness ranges from 7 to 15 microns.If a thicker paint layer is applied (around 200 microns), specialized technology can be used to create various textures and patterns such as leather, wood, or stone finishes on the surface.Applications of Pre-Painted Steel SheetPre-painted steel sheet offers high resistance to corrosion and rust, as well as good formability and pressability. For this reason, it is widely used in industries such as:Home appliancesIndustrial sheds and suspended ceilingsInterior and exterior building facadesOffice equipmentComputer and electronics metal componentsManufacturing of various tanks and drumsPrefabricated cabins and containersCold storage facilitiesAnd other related applications مطالعه
Galvanized steel sheet Galvanized steel sheet Galvanized steel sheet is one of the most common types of steel sheets. It is typically produced through the cold-rolling process and subsequently coated with zinc in a galvanizing process (commonly referred to as zinc coating or galvanization). The zinc coating prevents the steel sheet from oxidizing (rusting). As a result, this type of sheet exhibits high resistance to corrosion. From a technical standpoint, the stated thickness range appears unusually high for galvanized steel sheets (which are typically thinner). However, based on your text, the accurate English translation is:The thickness of galvanized steel sheets ranges from 6 to 18 mm, with lengths between 2 and 6 meters, and an approximate weight ranging from 8 to 30 kilograms.If you would like, I can also provide a technically corrected version based on standard industrial specifications.This type of sheet is also produced in another form, known as hot-dip galvanized steel. It is obtained by applying a galvanized coating to the surface of cold-rolled steel sheet (commonly referred to as oiled sheet) during the hot-rolling process. These sheets are resistant to impact, corrosion, and rust.Applications of Galvanized Steel Sheet Galvanized steel sheet is used in the following industries:Water transmission pipesCabinetWater storage tankssteel structure roof مطالعه
Hot Rolled Steel Sheet Hot Rolled Steel Sheet One of the most widely used types of steel sheets is hot-rolled steel sheet (commonly referred to as black sheet in the market). This type of sheet is informally known as “black sheet” due to its dull, non-reflective surface appearance, which results from the formation of mill scale during the hot-rolling process. Its typical surface color is matte gray. Hot-rolled steel sheet (commonly known as black sheet) is produced through the hot rolling process and should not be confused with hot-dip galvanized steel.This type of steel is typically manufactured from grades such as ASTM A36 and ASTM A1011. During production, steel slabs are heated in a reheating furnace to temperatures of approximately 1,200–1,280°C.In the next stage, the heated material passes through a series of rollers where the rolling process reduces its thickness to the required dimensions. During this stage, descaling is performed to remove surface scale (iron oxide) formed at high temperatures.Finally, after passing through finishing stands and a run-out cooling table, the steel strip is coiled and formed into hot-rolled steel coils. Applications of Hot-Rolled Steel Sheet (Black Sheet)Hot-rolled steel sheet (black sheet) is used in various industries. Some of its most common applications include the following:automotive body structureautomotive floor pan steel sheeWelded pipesTypes of structural steel sectionsTanker fabricationship construction مطالعه

Deformed Wire Coil Deformed Wire Coil Along with civil projects, from supply to quality control Rebar coils are tightly wound coils made of reinforcing steel bars. When their surface is ribbed , they are referred to as deformed wire coils. This type of rebar is classified into two grades: A2 and A3. The production process of wire coils is such that after the rebars are manufactured, they are coiled using special equipment. The steel used for these rebars is produced through steelmaking processes such as open-hearth furnaces , electric arc furnaces, and converters. This product is made from billet ingots by the hot rolling process and is then converted into various wires through cold drawing operations. Finally , the wire is formed into coils. The inner diameter of the coils is about 85 mm and their weight is approximately 22,000 kilograms. Applications of Deformed Wire CoilDeformed wire coils are used in various industries , including the following:Construction industryFabrication of trusses and joistsWire rope productionBarbed wire productionManufacture of wire mesh, fencing, and gabionsManufacture of nails, screws, and rivetsManufacture of metal chainsElectrode manufacturing and welding industryProduction of free-cutting wire rodsSpring manufacturing industryDownstream steel industries and steel conversion/processing industries مطالعه
Plain Wire Coil Plain Wire Coil Supplied in accordance with industrial and project standards. Wire rod (coiled rebar) is a type of rebar produced in the form of tightly wound coils. When its surface is smooth, it is classified as plain wire coil. These products are also known as wire rods. Rebars produced in smaller diameters can be coiled, resulting in coils with lower volume and easier handling , transportation , and storage. This type of wire coil includes several categories:Low-carbon wire coil: High ductility , good weldability, and excellent formability.Medium-carbon wire coil: Produced according to A1 standard, lower in price compared to deformed coils, and used in the rubber, tire , and spring industries.Welding electrode wire coil: Used as raw material for the production of welding electrodes. مطالعه
