Hemaokang Steel (Shandong) Co., Ltd. is proud to present our premium GB/T 11263 Q235B Carbon Steel H Beam, designed for heavy-duty structural applications. As a reliable manufacturer and exporter, we combine advanced hot-rolled and welded processes to deliver beams that meet international quality standards. Our H beams serve as the backbone of modern construction, offering exceptional load-bearing capacity, durability, and cost-efficiency. Whether you need beams for skyscrapers, bridges, or industrial plants, our products are engineered to perform under demanding conditions.
Each beam is manufactured in strict compliance with the Chinese national standard GB/T 11263, using Q235B carbon steel—a material known for its excellent weldability, formability, and moderate strength. Our production lines utilize both hot-rolling and high-frequency welding techniques, ensuring consistent dimensions, smooth surfaces, and reliable mechanical properties. With a wide range of sizes available, from 100×100 to 1000×400 mm, and lengths up to 12 meters or customized, we can accommodate diverse project requirements.
Key Features & Technical Specifications
- Standard Compliance: Fully meets GB/T 11263, ensuring consistent quality and performance.
- Material Grade: Q235B carbon steel with yield strength ≥ 235 MPa and tensile strength 370–500 MPa.
- Manufacturing Process: Available in hot-rolled (seamless structural shape) or welded (from steel plates) options to suit different budget and application needs.
- Dimensional Accuracy: Tight tolerances on flange width, web thickness, and overall height; typical deviation within ±2 mm.
- Surface Finish: Bare (mill finish) as standard; optional painting, hot-dip galvanizing, or anti-corrosion coating upon request.
- Weldability: Excellent for field welding, cutting, and drilling due to low carbon content.
- Versatility: Ideal for columns, beams, purlins, and support structures in buildings, warehouses, bridges, and machinery.

Frequently Asked Questions
Q: What is the difference between H beam and I beam?
A: H beam has equal or nearly equal flange widths, providing better load-bearing capacity and stability, while traditional I beam has tapered flanges. Our product complies with GB/T 11263 and is designed as H beam but can also be referred to as structural I beam in some markets.
Q: What sizes are available from stock?
A: We stock a wide range of common sizes from 100×100 to 400×400 mm. For larger or non-standard sizes, production lead time is typically 15–25 days. Please contact our sales team for current inventory.
Q: Can you provide cut-to-length service?
A: Yes, we offer cutting to your specified lengths, with tolerances of ±5 mm. Custom lengths are available upon request.
Q: What is the minimum order quantity (MOQ)?
A: Our MOQ for standard sizes is 10 metric tons. For non-standard sizes, MOQ may be 25 metric tons. Smaller trial orders are negotiable.
Q: Are your products tested for quality?
A: Yes, we perform 100% dimensional inspection and mechanical property tests on representative samples. Our ISO9001 quality system ensures traceability and consistency. Mill test certificates are provided with each shipment.
Q: What packaging options do you offer for export?
A: Beams are bundled with steel straps, with protective layers for sea freight. We can also apply waterproof paper, wooden crates, or anti-rust oil as needed. Packaging is designed to prevent damage during long-distance transport.
Q: Do you provide third-party inspection services?
A: Yes, we welcome inspection by SGS, BV, or other accredited agencies at the buyer's cost. Our factory is open for pre-shipment inspection.
Q: What is the delivery time for a typical order?
A: For standard sizes in stock, delivery is within 7–10 days after payment. For production orders, lead time is 20–30 days depending on quantity and size. We work to meet urgent deadlines whenever possible.
