Long-Span Steel-Concrete Composite Beam

Long-Span Steel-Concrete Composite Beams: Revolutionizing Modern Construction

Shenyang Zhongda Steel Structure Engineering Co., Ltd. is a leading manufacturer and supplier of Long-Span Steel-Concrete Composite Beams. Our advanced technology, rigorous quality control, and innovative design set us apart in the industry. We offer superior load-bearing capacity, cost-effectiveness, and customization options that meet the diverse needs of large-scale construction projects.

Product Description:

Our products combine the strength of high-grade steel with the durability of reinforced concrete. These beams are engineered to span greater distances while maintaining structural integrity, making them ideal for commercial buildings, bridges, and industrial facilities. The steel skeleton, typically made from Q345B/C high-strength steel, works in perfect harmony with C40-C60 grade concrete (compressive strength ≥50 MPa) to create a robust, long-lasting structural element.

Product Features:

• Superior load-bearing capacity for extended spans
• Excellent fire resistance and sound insulation properties
• Reduced overall structural weight compared to traditional concrete beams
• Faster construction time due to prefabrication possibilities
• Versatile design options to suit various architectural requirements

Packaging and Delivery:

At our company, we place great emphasis on the secure packaging and timely delivery of our products. Our dedicated packaging team uses high - quality materials, such as thick cardboard boxes and protective foams, to ensure that each item is well - safeguarded during transit. For standard specifications, we are committed to delivering within 30 days. However, for complex designs that require more intricate manufacturing processes, including a necessary 7 - day curing period for materials like concrete or certain adhesives, the delivery may take up to 45 days. This ensures that every product reaches our customers in perfect condition and within a reasonable time frame.

FAQ:

Q: What is the maximum span these beams can achieve?
A: Our products can span up to 30 meters, depending on the specific design and load requirements.
