YS STEEL produces I beam steel using advanced hot-rolling mills that ensure consistent cross-sectional dimensions, tight tolerances, and uniform mechanical properties along the entire length of each beam. The hot-rolling process also improves the grain structure of the steel, resulting in better ductility, weldability, and impact resistance compared with cold-formed alternatives.
YS STEEL supplies I beam steel in a comprehensive dimensional range. The standard height of our beams ranges from 100 mm to 900 mm, flange widths from 55 mm to 300 mm, and web thicknesses from 4.1 mm to 16.5 mm. We also provide custom profiles for special engineering requirements. Standard lengths are 6 meters, 9 meters, 12 meters, and customized cut-to-length options are available upon request.

I beam steel is used wherever large loads must be supported over long spans without excessive deflection. Common applications include:
YS STEEL understands that different environments require different levels of corrosion protection. We supply I beam steel with the following surface treatments:
YS STEEL has over two decades of experience in manufacturing and exporting structural steel products. We maintain large monthly production capacity and keep a strong inventory of common sizes, allowing us to fulfill urgent orders with short lead times. Our sales engineers provide free technical support, including load calculation guidance, material selection advice, and cutting optimization to reduce waste and cost.
Every I beam steel shipment from YS STEEL is bundled with steel straps and loaded into containers or bulk vessels according to the destination port requirements. We handle all export documentation, including certificate of origin, commercial invoice, packing list, and mill test certificates. Our quality control team follows each order from raw material to dispatch, ensuring that the beams arrive on site ready for immediate fabrication.
I beam steel and H beam steel both have an I-shaped cross-section, but their flange proportions differ. I beam steel, also known as IPE or universal beam, typically has tapered flanges that are narrower than the overall height, while H beam steel has parallel, wider flanges that are approximately equal to or greater than the beam height. I beam steel is generally lighter and more efficient for bending resistance in one direction, making it ideal for long-span beams where vertical loads dominate. H beam steel provides better resistance to lateral bending and is often used as columns or piles. YS STEEL supplies both profiles, but I beam steel is the preferred choice for floor beams, roof beams, and bridge girders where weight saving is critical.
Selecting the correct I beam steel size depends on three main factors: the span length, the magnitude and distribution of the load, and the allowable deflection. The beam height is the primary driver of bending resistance, while the web thickness controls shear capacity. You should first calculate the maximum bending moment and shear force, then compare those values with the section modulus and shear area of the selected beam. The grade should be chosen based on the required yield strength, temperature conditions, and weldability. For general building construction, ASTM A36 or S235JR is sufficient. For higher loads or lighter structures, A572 Gr 50 or S355JR is recommended because of its 345–355 MPa yield strength. YS STEEL provides free section property tables and load span charts to help customers make the right selection without over-engineering the beam.
YS STEEL manufactures I beam steel in full compliance with the following international standards: ASTM A36, ASTM A572, ASTM A992 for the American market; EN 10025-2 S235JR, S275JR, S355JR, and EN 10034 for the European market; JIS G3101 SS400 for the Japanese market; and GB/T 706 Q235B, Q355B for the Chinese market. Each production batch is tested and certified according to the specific standard stated in the order. We also supply dual-certified beams, such as A36/S235JR or A572 Gr50/S355JR, to simplify international project specifications and reduce inspection costs.
Yes, YS STEEL offers cut-to-length services for I beam steel in lengths from 1 meter up to 24 meters, depending on the profile size. We can also perform end plate welding, coping, notching, drilling, and galvanizing in our fabrication workshop. If you need pre-drilled connection holes, simply provide the hole positions, diameters, and tolerances, and we will handle the machining before surface treatment. This service saves significant time on site and ensures that all beams arrive ready for bolted assembly. Custom lengths and fabrication details are quoted on a project basis with a short lead time.
