We supply carbon‑steel I‑beam in multiple specifications. Available surface options include hot‑rolled black finish, anti‑rust painted and hot‑dip galvanized. Secondary processing service such as cutting, drilling, punching and OEM marking are supported. Suitable for EPC contractors, steel fabricators, overseas importers and large construction projects.
Product Description
Our I‑beam steel is manufactured from premium carbon steel by hot‑rolling technology. Strict dimensional tolerance ensures flat flanges, straight web and stable mechanical performance.
This structural I‑beam has excellent weldability and machinability. It can be cut, drilled and processed for onsite assembly. Hot‑rolled black finish is widely used for indoor steel‑structure projects; painted or galvanized surface is available for outdoor anti‑corrosion requirements.
Standard lengths are 6m,9m,12m. Custom cut‑to‑length is acceptable according to project drawings. All products adopt seaworthy steel‑strip bundling packing for long‑distance ocean shipment.

FAQ
Q1: What is I beam steel used for?
A: I‑beam steel is primary structural steel member, widely used for main beam and column of steel workshop, building, bridge, heavy‑duty equipment base and industrial platform.
Q2: What is difference between I‑beam and H‑beam?
A: I‑beam has narrower flange width, mainly for beam to bear bending load; H‑beam has wider flange, better for column bearing vertical pressure.
Q3: Can you provide custom cut‑to‑length service?
A: Yes, custom cutting is available. Extra processing cost depends on drawing specification and order quantity, please send inquiry with your requirement.
Q4: Which surface finish for outdoor project?
A: Anti‑rust painted or hot‑dip galvanized I‑beam is recommended for outdoor environment. Hot‑rolled black is fit for indoor dry projects.
Q5: What standards can you supply?
A: We support ASTM A36, GB, EN and JIS standard. Please specify required standard when sending inquiry.
Q6: Can you do drilling and hole punching?
A: Yes, we provide secondary processing including drilling, punching and marking. Please attach technical drawing for accurate quotation.
Q7: What is your MOQ?
A: MOQ is 1 ton. Mixed different sizes within one order is acceptable.
