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
Light section I-beam Light section I-beam One type of I-beam is the H-beam, which is produced in both light and heavy versions. In general, an H-beam is a type of section whose flanges are wider than those of other I-beams. For this reason, it offers greater resistance to compression and bending and is most commonly used in the construction of columns, bridges, and beams. The light H-beam is also known as IPBA or HEA. Its height is smaller than its width. In addition, the thickness of its web and flanges is lower than that of the heavy type. The web thickness of this H-beam ranges from 55 to 17 mm17 mm, and the flange thickness is approximately 88 to 31 mm31 mm. It is also priced lower than the heavy type. تیر آهن معمولا در سایز 6 تا 14 متر تولید می شود و در بازار موجود است. از نظر استاندارد هم در ایران معروفترین آن برای تولید پروفیل های ساختمانی، استاندارد اروپایی است. مطالعه
Heavy I-beam Heavy I-beam The most widely used type of beam in the construction industry is the wide-wing beam, which has a shape similar to an H. For this reason, it is also known as a "hash" beam. This type of profile is produced in light and heavy versions, which have different uses. H beams, with a wider wing design, are stronger and heavier than conventional models. This type of beam is usually used in the construction of columns, bridge beams, buildings and engineering structures. The height of heavy beams is equal to their width. The web thickness of this type ranges from 6 to 19 mm and the flange thickness is 10 to 36 mm, which is thicker than the light type. As a result, it has greater resistance and is also more expensive. مطالعه
Profile A profile, also known as a section, refers to a long product with a constant cross-section. It is used in various industries, including construction and machinery manufacturing, to produce metal components in a wide range of shapes.These sections are produced in a wide variety of shapes and types, each with its own specific application.Therefore, profiles are produced in various lengths, typically 66 and 12 m12 mApplications of Steel SectionsProfiles come in a variety of shapes. Smaller sections are used for metal railings, while larger sections—commonly referred to as columns—are used in columns and steel frame structures. In general, profiles are used for doors and windows, fencing around factory walls, staircases, sidewalks, and street applications. Column section They are steel sections used vertically in building frames to carry compressive loads. Z-profile It is a type of construction material shaped like the English letter Z and is considered one of the open-section profiles. Lightweight profile It is a steel section with a cross-section that remains completely uniform along the entire length of the product, and it is manufactured from cold rolling or from cold-rolled (oiled) sheet. Open-section profiles Open-section profiles refer to profiles whose cross-sections are open. Industrial profile Industrial profiles are manufactured from thick hot-rolled steel sheet (black sheet) and are supplied to the market in a wide range of types and sizes. Door and window profiles They are steel or aluminum sections with specific shapes, used to manufacture door and window frames. مطالعه
Industrial profile Industrial profile Industrial profiles, also known as heavy profiles, are made from various materials and are used in both construction and industrial applications. Industrial profiles fall under the category of built-up (compound) profiles and are formed by combining hot-rolled and cold-formed sections. These profiles are produced in a variety of shapes, each designed for a specific use. Key advantages of industrial profiles include low weight, high strength, and durability—remaining resistant to deterioration over time, even in moist environments or near water. Industrial profiles are used in large steel structures, including the construction of bridges, large-scale advertising billboards, military industries, and the manufacturing of industrial equipment, among others. They are also used in structures built in factories and production workshops, where different parts require steel columns and box sections. مطالعه
Column section Column section A column box section is a type of box profile manufactured from hot-rolled (black) sheet in dimensions of 400×400 mm400×400 mm. These box sections are used for applications such as building steel sheds (industrial buildings), workshops, building columns, and warehouses. In general, these profiles are produced and packaged in 12 m12 m lengths. The weight of column box sections varies depending on the hot-rolled sheet thickness used in their production. Compared to other types of profiles, these profiles offer lower weight, better cost-effectiveness, acceptable technical and operational specifications, a lower elongation ratio, and a more favorable cross-sectional profile.Column Profile ApplicationsColumn profiles have various applications, including the following:Automotive industryManufacturing various types of metal tables and chairsHome appliances such as various metal dining setsFurniture industryManufacturing various types of protective barriers in public spaces, such as parksCivil engineering and construction, such as pedestrian overpasses مطالعه
Open-section profiles Open-section profiles Profiles with an open cross-section are classified as open sections or cold-formed steel sections. Examples of these profiles include Z profiles, single-sided and double-sided gutter profiles, as well as French profiles. These profiles are manufactured in various thicknesses and dimensions. An open section has a distinct gap between its two edges, and the span of the opening from one edge to the other is what distinguishes it from a closed section. Open sections are generally more cost-effective and more competitively priced than closed sections. Other advantages include high strength, light weight, and easy installation. مطالعه
Z-profile Z-profile Profiles manufactured with a Z-shaped cross-section are also commonly known as Z purlins and are classified as open sections. The production process for these profiles is relatively complex and is carried out using the hot rolling method. Z-profile sizes and dimensions are available in a wide range and are manufactured based on market and customer requirements. The maximum steel grade used for these profiles is up to ST52. Z profiles are produced using hot-rolled (black) sheet or cold-rolled (oiled) sheet. The sheet sizes can be 16, 18, 20, and 22, with thicknesses of 22, 2.5 , and 3 mm3 mm. In the market, Z profiles are commonly referred to as Z16, Z18, Z20, and Z22. The number after “Z” indicates the height of the Z profile. Another characteristic of Z profiles is the presence of slotted punching (commonly known as kidney-shaped holes).
