Rebar
starstarstarstarstarRebar is a steel rod integral to modern construction, significantly reinforcing concrete against tensile and rotational forces. Its use allows for thinner, more cost-effective concrete layers, enhancing structural integrity. Ribbed rebar, common in construction, ensures stronger bonding with concrete and reduces damage risks. Originating in the 1800s, rebar's role has evolved, becoming crucial for earthquake-resistant structures. Its implementation in construction not only strengthens but also simplifies building processes, making it a cost-effective, essential material in the building industry.

Round Bar & Flat Bar
starstarstarstarstarand extend their length. This process involves three roughing stages, followed by cutting the heated rebars to specific lengths using measuring shears, bypassing the ribbing stages. This efficient method ensures the production of quality rebars.
A "flat bar" or steel strap is a versatile low carbon steel product, used primarily for securing heavy loads and in construction for its high durability. Available in various sizes and materials like galvanized steel and stainless steel, it's suitable for cutting, drilling, and welding. Its applications range across industries, from securing objects in packaging to manufacturing in the household appliances, automotive, and construction sectors. Flat bars are crucial in making grating for buildings and industrial setups due to their strength and aesthetic appeal.To manufacture rebar, billets are heated in furnaces to 1100°C and then rolled to reduce their diameter More Info
Wire Rod
starstarstarstarstarRebar coils are categorized into two main types: plain and ribbed. Plain rebar coils, similar to wire rods, are typically available in sizes from 5.5 to 12 mm. Ribbed rebar coils, divided into A2 and A3 groups, are formed into coils after rolling. Additionally, rebar coils are classified based on carbon content into low, medium, and high carbon categories, each with distinct mechanical properties. These rebars are used not only in construction but also in various industries for manufacturing items like springs, cables, and automotive parts.

I Beam & H Beam
starstarstarstarstarI-beams, essential in construction, are steel profiles used for building frameworks, columns, and beams. They come in two shapes: the English letters H and I. H-shaped beams, known as H-beams, provide stability for large structures like commercial complexes, while I-shaped beams, especially the widely used IPE type, are common in various building projects. Made of steel, I-beams are produced in lengths of 6 or 12 meters, consisting of a web (horizontal section) and flanges (vertical parts). Their manufacturing standards, like European, Chinese, or Russian, influence their characteristics and applications in construction, including use in framework, load-bearing structures, and architectural features.

U Channel
starstarstarstarstarSteel U-channels, resembling the letter 'U', consist of a horizontal base known as the web and two vertical sides called flanges. Widely used in construction for their optimal shape, U-channels vary in production methods and final forms. The Iranian National Standards Organization only specifies standards for hot-rolled U-channels, but European and Russian standards also provide valuable information. U-channels are typically categorized into two production processes.
Hot-Rolled U-channels: These are formed when heated raw billets pass through rollers, shaping them into U-channels. The size of the rollers determines the size of the U-channels, often referred to as factory-standard U-channels. More Info
Angle
starstarstarstarstarAngle iron is a versatile steel profile with a characteristic 'L' shape, available in equal or unequal lengths. It's primarily used in construction for structural support and bracing. Varieties include galvanized, spiral, stainless steel, and aluminum angle irons, each serving specific industries like marine, chemical, and electrical due to their unique properties like corrosion resistance. Angle iron is produced in both fabricated and pressed forms, suitable for a range of applications in building and industry.

Hot Rolled Coil & Sheet (HRC/HRS)
starstarstarstarstarHot-rolled steel sheets, known as "hot plates" or hot-rolled steel, are key products in the steel industry. This process heats steel slabs above 930°C, then compresses and flattens them into sheets, known as black steel sheets. Renowned for their strength, durability, and adaptability, these sheets have widespread uses in construction, automotive manufacturing, machinery, and home appliances. Their versatility makes them ideal for structural components and various industrial applications.

Cold Rolled Coil & sheet (CRC/CRS)
starstarstarstarstarCold rolled sheet steel, produced via cold rolling under high pressure, is renowned for its strength and durability. These sheets, heated temperature and 200°C, undergo a process enhancing their thickness and resilience. The oiling stage post-production grants them a glossy finish and resistance to corrosion and oxidation. Ideal for construction, automotive, and appliance manufacturing, oil sheets offer excellent formability, tensile strength, and water resistance. They are distinct from hot rolled sheets and have advanced significantly, providing precise control over their technical specifications for diverse industrial applications.

Hot Dip Galvanized Sheet (HDGI)
starstarstarstarstarGalvanized steel sheets are pivotal in various industries due to their high resistance to corrosion and rusting. The galvanization process, particularly hot-dip galvanizing (HDG), involves applying a zinc coating to steel, enhancing its durability. The quality of these sheets depends on the zinc coating's weight, typically between 100 to 350 grams per square meter, with thicker coatings offering better protection. There are two primary types of galvanized sheets: Z (pure zinc coating) and ZF (zinc with iron content). The appearance of these sheets is characterized by Spangle patterns (crystallized zinc impurities), which vary in size and help identify the manufacturing source. Galvanized sheets are extensively used in construction, automotive, and appliance industries, where they are prized for their strength and flexibility.

Hollow Section (Profile)
starstarstarstarstarProfiles are essential in construction, available in lengths usually 6 and 12 meters, with prices varying based on dimensions and material. Civil engineers select profiles for building stability, balancing safety and cost. They come in two types: light profiles, made from oil sheets via cold rolling (standards DIN2394, EN10219-2), and heavy profiles, identified by weight and made from black sheets thicker than 1.5 mm. Galvanized profiles offer high safety and corrosion resistance, ideal for northern climates and UPVC windows. Composite profiles, resistant to corrosion, suit earthquake-prone areas due to their lightweight and durability. Profiles, both open (like Z and U shapes for frames and exteriors) and closed (used in windows, doors, and modern shutters), increase structural strength while keeping construction light.

Pipe
starstarstarstarstarWelded pipes are manufactured by welding edges of rectangular steel sheets, allowing for precise size customization. They utilize high-frequency electric currents for welding, enhancing strength and corrosion resistance. Seamless pipes start from a steel billet, heated and stretched to desired dimensions, ideal for high-pressure applications. Key differences include size flexibility, with welded pipes accommodating a broader range, and cost-effectiveness, where seamless pipes excel in specific scenarios. Material choice is wider for welded pipes, while seamless pipes offer a uniform, joint-free structure. Each type has its advantages, with welded pipes providing size and cost benefits, and seamless pipes ensuring consistent strength without weld seams.
