Reference catalog values; the table represents profile dimensions and nominal theoretical mass, not confirmed stock. *For tapered-flange beams, flange thickness is a reference dimension; use the applicable profile standard for the complete geometry.
Overall section height measured between outer flange faces.
Overall flange width determines connection and support detailing.
Web thickness and shape are selected from the relevant section designation.
See how the profile, root fillet and flange shape affect the dimensions you specify for steelwork fabrication.
Show the full I profile and clear flange/web intersections with realistic hot-rolled geometry.
Confirm whether your drawings call for parallel or tapered flange faces and the correct section series.
Estimate nominal tonnage from the selected profile's kg/m, finished length and quantity. Use the output for initial pricing and freight planning.
Formula: catalog kg/m × cut length (m) × number of beams ÷ 1000 = total metric tons. Final settlement follows the agreed weighing method and tolerances.
Supplier confirmation covers material grade, production or inventory route, and delivery availability.
Source the structural section specified for your fabrication drawings, project loading and assembly requirements.
Rolled beam members incorporated into structural frames, floors and welded assemblies.
I beam sections for equipment supports, fabricated frames and material-handling structures.
Beam members specified for warehouse and industrial building frames.
Horizontal steel members for engineered platform and access systems.
Fabricated I sections for frames, bases and plant structures.
Secondary beam members selected from structural calculations.
I-beam support members in fabricated handling installations.
Repeated cut lengths and section series for industrial fabricators.
Combine a clear section schedule with manufacturing-scale supply, inventory checks, material documentation and export coordination.
Our actual annual steel production across product categories supports recurring purchase planning and industrial procurement.
Manufacturing ↗Our combined steel inventory supports supply coordination. Your exact I section size and grade are confirmed for each RFQ.
Steel Inventory ↗Include profile standard, material grade, section dimensions and MTC requirements to define the order clearly.
Quality Control ↗Share lengths, bundle quantity, destination port and packing requirements for your shipment quotation.
Contact Sales ↗BAOSTEEL METAL operates at an annual steel production scale of 8 million metric tons across its product range. Send the material grade and exact I section designation to confirm the suitable supply and delivery arrangement for your order.
Share your profile, grade, length and number of beams to request a current supply check. Our sales team will confirm availability and lead-time information for your exact order.
Set the required section dimensions, straightness, material identification and testing scope with your purchase order. We will confirm the applicable document package.
Include cut lengths and approved drawings when your order requires prepared I beam components. Cutting and drilling arrangements can be confirmed against beam section, length and tolerance.
Your beam lengths, bundle quantities, transport requirements and discharge port determine the agreed loading and shipment arrangements.
Find wider flange beams, structural profiles and related product categories for your procurement schedule.
Share the section designation and dimension standard, steel grade, cut lengths, quantities, inspection scope and destination port.
Specify the exact series and size. IPE sections have parallel flanges, while IPN and typical GB I sections use tapered flange profiles. Each series has its own nominal dimensions and weights.
Multiply the section's nominal kg/m by the cut length in metres and number of pieces. Divide the result by 1,000 to estimate metric tons.
Attach your drawing, required material grade, cut lengths and MTC or additional inspection scope with your enquiry. These details can be confirmed as part of your quotation.
