As a leading manufacturer from Hemaokang Steel (Shandong) Co., Ltd., established in 2025 with an annual export value exceeding US$50 million, we take pride in offering our Factory Direct H-Shaped Steel Beam Q345B with custom sizes and comprehensive technical support. Our state-of-the-art production lines and strict quality control ensure that every beam meets international standards, providing you with a reliable, cost-effective solution for your structural needs. Whether you're constructing high-rise buildings, bridges, or industrial plants, our H-beams deliver superior strength, durability, and precision.
Our Q345B H-shaped steel beam is made from low-alloy high-strength steel, offering excellent weldability, machinability, and impact resistance. With a minimum yield strength of 345 MPa, it is widely used in load-bearing structures where both weight savings and strength are critical. We offer custom sizes to match your exact design requirements, supported by our experienced engineering team who can provide technical guidance from selection to installation.

Frequently Asked Questions (FAQ)
-
Q: What is the minimum order quantity (MOQ) for custom H-beams?
A: Our MOQ for custom sizes is typically 10 tons. However, we can accommodate smaller quantities for sample orders or trial projects. Please contact us for details. -
Q: Can you provide third-party inspection reports?
A: Yes, we can arrange inspections by SGS, BV, or other accredited agencies at an additional cost. Our standard mill test certificates are included free of charge. -
Q: How long does custom size production take?
A: Lead time depends on the complexity and volume. For standard custom sizes, production usually takes 15–25 days after order confirmation. Urgent orders can be expedited upon request. -
Q: What surface treatments are available for Q345B H-beam?
A: We offer as-rolled, pickled & oiled, painted (various colors), and hot-dip galvanized finishes. Please specify your requirements when ordering. -
Q: Do you offer technical drawings or load capacity data?
A: Yes, our engineering team can provide cross-sectional properties, moment of inertia, and load tables for your custom dimensions. We also support CAD drawings upon request. -
Q: Is the Q345B material suitable for low-temperature environments?
A: Q345B has good toughness down to -20°C. For colder climates, we recommend Q345D or Q345E with enhanced low-temperature impact properties. We can advise on the best grade for your project. -
Q: How do you ensure the dimensional accuracy of custom beams?
A: We use CNC-controlled rolling and cutting equipment, and each beam is inspected with calibrated tools. Tolerances meet GB/T 11263-2017 standard, typically within ±2mm for flange width and web thickness. -
Q: What payment methods do you accept?
A: We accept T/T (bank transfer), L/C (irrevocable at sight), and sometimes Western Union for small amounts. Flexible terms are available for long-term partners.
