Q355B High Strength Embedded Steel Plate Connector For Connecting Steel Structures

Product Description
An Embedded Steel Plate Connector is a foundational fixing solution designed for connecting steel structures to concrete substrates (foundations, walls, columns), manufactured with Q355B high-strength steel plates (thickness 10-30mm) and HRB400 threaded steel anchor bars. This product features a reliable load transmission mechanism—anchor bars (diameter 16-25mm) are welded to the steel plate via fillet welds (weld leg length ≥8mm), ensuring strong bonding with concrete (pull-out load capacity ≥30kN per anchor bar) and transferring steel structure loads to the concrete foundation. The steel plate is prefabricated with precision bolt holes (CNC punching, tolerance ±0.5mm) for on-site steel structure docking, enabling rapid assembly without on-site drilling. The surface is treated with hot-dip galvanizing (zinc layer thickness ≥85μm) or anti-corrosion paint, providing salt spray resistance ≥1200 hours and adapting to underground, outdoor, and industrial environments. The embedded design ensures structural stability—during concrete pouring, the plate is positioned with fixtures (alignment error ≤5mm) to avoid displacement, and the anchor bar’s bent or hooked end enhances anchoring force in concrete. It complies with GB 50010 concrete structure design code and GB 50205 steel structure construction standards, suitable for steel column foot fixing, curtain wall keel anchoring, bridge bearing foundations, and prefabricated concrete component connections. Professional services include embedded depth calculation, positioning fixture design, and on-site installation guidance, ensuring the connector meets foundation load requirements.

Applications
Embedded Steel Plate Connectors are critical foundational fixing solutions widely used in construction, infrastructure, and industrial projects. Certified by GB 50010 and ISO 9001, they meet strict quality standards for concrete-steel connection, ensuring reliable performance in load-bearing scenarios. These connectors are suitable for diverse applications, including steel column foot fixing in industrial workshops and office buildings, curtain wall keel anchoring (glass, stone, metal curtain walls) in commercial complexes, bridge bearing and pier foundation connections, prefabricated concrete component splicing (beam-column joints), and equipment foundation anchoring (heavy machinery, generators). They are essential for projects where steel structures need stable integration with concrete substrates, such as high-rise buildings, bridges, and industrial facilities. The minimum order quantity is 10 pieces for standard specifications (plate size 200×200mm-500×500mm, thickness 10-30mm), and customized solutions are available for plate size, anchor bar diameter/length, and bolt hole layout to meet specific foundation design needs. Competitive pricing and bulk purchase discounts (for orders over 100 pieces) enhance cost-effectiveness, while the delivery time (5-10 workdays for prefabricated plates) supports foundation construction schedules. With a monthly supply capacity of 5,000 pieces, the manufacturer ensures timely delivery even for large-scale infrastructure projects. The Q355B steel plate and HRB400 anchor bars, combined with anti-corrosion treatment, ensure durability in underground (moisture), outdoor (weathering), and industrial (pollution) environments. Customization options also include stainless steel (316L) material for coastal or chemical-corrosive foundations and enhanced weld strength (full penetration welds) for heavy-load applications. Whether it's for new foundation construction or old structure reinforcement (steel structure addition), the Embedded Steel Plate Connector delivers stable and reliable concrete-steel connection performance.
