Also, free sample is available.
Our export-grade prestressed bearing plates are manufactured from high-quality cast steel using precision casting techniques; they feature a robust, solid structure with precision-machined bearing surfaces. Essentially, the plate functions by evenly distributing the concentrated stress transferred from the anchor head to the surrounding concrete, thereby preventing structural damage caused by excessive stress concentration. The integrated grouting holes are precisely positioned to ensure smooth grouting operations and dense filling of the ducts, effectively protecting the steel strands against corrosion. During manufacturing, we place strict controls on plate flatness and hole coaxiality, ensuring excellent compatibility with matching anchor heads and spiral reinforcement; this simplifies on-site alignment and installation, reducing potential difficulties for construction personnel during the tensioning phase.
These products comply with the domestic GB/T 14370 standard and meet industry specifications such as JT/T 329 (highways) and TB/T 3193 (railways), making them compatible with a wide range of prestressing anchorages. Our product lineup includes single-hole plates as well as multi-hole circular and flat anchor bearing plates, designed to accommodate mainstream steel strand sizes such as Φ12.7mm, Φ15.2mm, and Φ17.8mm.
We manufacture bearing plates with a wide range of capacities, accommodating anywhere from 1 to 55 strands. Smaller plates are designed for compact precast components, while high-tonnage, multi-hole plates suit large bridge elements like box girders and T-beams. Flat anchor plates are ideal for space-constrained applications, such as floor slabs and thin-walled box girders.
The manufacturing precision of the prestressed bearing plate directly impacts the structural performance of the anchorage zone. The flatness of the end face must be within 0.5 mm, and the hole diameter tolerance is strictly controlled between +1 mm and -0 mm. During installation, the positioning accuracy of the embedded duct must be within 5 mm; the corrugated duct must be perpendicular to the bearing plate, and the connection point must be tightly sealed. The axis of the spiral reinforcement must align with that of the corrugated duct, with a spacing of no less than 5 cm to ensure effective confinement of the concrete beneath the anchor. Additionally, the bearing plate end face typically features a G3/4 threaded grouting port to facilitate subsequent duct grouting operations.
These products are suitable for a wide range of prestressing applications, including highway and railway bridges, urban interchanges, high-rise buildings, hydroelectric power stations, slope stabilization, large storage tanks, and precast railway sleepers. Selection depends on factors such as the number of steel strands, design tensioning force, and component thickness; our technical team can provide recommendations based on project drawings to ensure the correct specifications are chosen.
As a direct manufacturer with extensive experience exporting prestressed components, we offer custom, non-standard production based on client drawings-including special shapes and custom hole configurations-and can engrave project numbers or brand logos onto the plate surface. We provide quality inspection reports and factory documentation for all export batches to meet the requirements of overseas project inspections and supervisory audits. We handle everything from small sample orders to large-scale project batches, utilizing anti-rust treatment and reinforced wooden crate packaging to prevent damage during maritime transport.
