Rongheng Intelligent Manufacturing supplies Steel I-Beams for structural frames, industrial buildings, bridges, equipment bases and other steel structures where section geometry and load requirements need to be matched carefully. Our available range covers 10#–63# Chinese standard I beams, with Q235B, Q355B, SS400 and A36 grades available according to project requirements. European and British standard sections can also be supplied.
The I-shaped cross-section combines a web with upper and lower flanges, giving the profile useful bending performance while keeping the section relatively efficient in material distribution. For structural applications, the actual selection should be based on span, load, section dimensions, steel grade and connection conditions rather than relying on size alone.
The web and flanges form the main load-carrying profile. Dimensional accuracy and the relationship between the web and flanges are important when beams are connected, assembled or processed on site.
Q235B, Q355B, SS400 and A36 can be supplied for different project specifications. The required grade should be confirmed together with the applicable design or material standard.
The supplied material can be used for common fabrication operations such as cutting, drilling and welding, subject to the selected grade and project processing requirements.

For Steel I-Beams, dimensional consistency affects both structural assembly and subsequent fabrication. Rongheng controls key product dimensions during production and inspection, with attention to section size, straightness, twist and the alignment between flanges and web.
This is particularly relevant for projects involving repeated beam connections or prefabricated steel components, where dimensional deviations can create additional adjustment work during installation.
Different markets and engineering projects may specify different material standards. We can arrange I beams according to Chinese, European or British standard requirements after confirming the project specification before production.
For standard orders, 6 m, 9 m and 12 m lengths are commonly available. When the project requires specific cutting lengths, the required dimensions can be confirmed before production so that the delivered material corresponds with the fabrication plan.

Rongheng Intelligent Manufacturing is backed by steel production and supply resources in Daqiuzhuang, Tianjin. As the international sales platform of Tianjin Gefu Steel, we coordinate steel material supply for overseas projects and export orders, including specification confirmation, material selection, processing requirements and shipment arrangements.
For larger orders, the required section size, grade, length, surface treatment and applicable standard can be confirmed before production. We also accept smaller trial orders, allowing specifications and application requirements to be checked before a larger supply arrangement.
The appropriate section depends on the actual span, load, support conditions, steel grade and structural design. Send us the basic project parameters and required standard, and we can help match the available section range.
Yes. Standard lengths include 6 m, 9 m and 12 m, while cut-to-length supply can be arranged according to the confirmed project dimensions.
Yes. The available surface options include black steel, hot-dip galvanized and painted finishes. The required surface treatment should be confirmed before production.
Yes. In addition to Chinese standard I beams, European and British standard sections can be supplied according to the required specification. The standard, grade, section and quantity should be confirmed before ordering.
Q235B, Q355B, SS400 and A36 are available within the stated product range. The appropriate grade depends on the project specification and applicable material standard.
