Product Overview

Precast concrete beam connectors are engineered steel connection components used to securely connect precast beams to columns, walls, or other structural elements. They are designed to transfer shear, tensile, and compressive forces while maintaining accurate alignment during installation.
Compared with traditional cast-in-place connections, precast beam connectors significantly reduce on-site welding, shorten installation time, and improve assembly accuracy. They are widely used in commercial buildings, industrial facilities, parking structures, warehouses, modular construction, and infrastructure projects where fast construction and dependable structural performance are required.
We manufacture OEM precast beam connectors based on customer drawings, structural requirements, and international project specifications. Every component is produced using precision CNC processing and controlled welding procedures to ensure consistent fit-up and reliable installation on site.

Key Features & Manufacturing Advantages

1. Zero-On-Site-Adjustment Fit-Up
Cumulative dimensional errors in connection hardware lead to costly field reaming and installation delays. By machining mounting slots, hole layouts, and profiles in a single CNC setup, we hold strict tolerances (±1.0 mm or per ISO 2768-m). This ensures precast members align quickly and seat smoothly on site without secondary modification.
2. Certified Structural Load Transfer & Weld Integrity
Load transfer reliability depends on full penetration and defect-free welds. Our fabrication follows certified WPS (Welding Procedure Specification) guidelines executed by qualified welders (AWS D1.1 / EN ISO 5817 Level C). Critical load-bearing joints can undergo Ultrasonic Testing (UT) or Magnetic Particle Testing (MT) before coating to verify structural integrity under design shear and tensile loads.
3. Traceable Structural Material Grades
We source certified structural steel tailored to your regional design codes, offering complete chemical and mechanical traceability via EN 10204 3.1 Material Test Certificates (MTC).

Carbon & Alloy Steels: Q235B, Q355B, ASTM A36, ASTM A572 Grade 50, S355JR
Stainless Steels: AISI 304, AISI 316 / 316L for high-salinity or corrosive environments

4. Application-Specific Corrosion Protection
To ensure design service life across varied exposure conditions, surface finishes are applied under strict process control:

Hot-Dip Galvanizing: ISO 1461 / ASTM A123 compliant (coating thickness up to 85 μm for long-term outdoor durability)
High-Performance Finishes: Electro Zinc Plating, Zinc Flake (Geomet/Dacromet), and Custom Epoxy Primers

Quality Control from Engineering to Job Site

1. DFM (Design for Manufacturability) Review
Our engineering team conducts a thorough drawing analysis prior to production. We evaluate weld access, plate thickness, and bending radii to optimize manufacturability, reduce material waste, and lower your overall unit cost.

2. Precision CNC Processing
All perimeter profiles, mounting slots, and bolt holes are laser-cut and CNC-drilled in a single setup. This process eliminates cumulative dimensional errors, ensuring true center-to-center hole spacing for effortless field bolting.

3. Certified Structural Welding & NDT Inspection
Full-penetration welds and structural fillet welds are executed by certified welders in accordance with WPS guidelines. We offer Non-Destructive Testing (NDT)-including Ultrasonic Testing (UT) and Magnetic Particle Testing (MT)-to verify weld integrity before surface coating.

4. Heavy-Duty Export Packaging & Traceability
To ensure components arrive undamaged and installation-ready, products are packed on reinforced steel or fumigated wooden pallets, wrapped in VCI anti-corrosion film, and securely strapped. Every shipment includes batch heat numbers mapped to raw material certificates.

FAQ

Q: Do you supply EN 10204 3.1 Material Test Certificates (MTC)?

A: Yes. Every shipment includes raw material MTCs detailing heat numbers, chemical composition, and mechanical properties (yield/tensile strength) for full traceability.

Q: What drawing formats do you require for quotation?

A: We accept standard 2D drawings (PDF, DWG, DXF) and 3D CAD models (STEP, IGES). If you only have preliminary structural sketches, our engineering team can assist in finalizing production-ready drawings.

Q: What is your typical lead time for prototypes and production orders?

A: Sample and prototype production typically takes 7–10 working days. Mass production lead time is generally 20–30 days, depending on order volume and surface finishing requirements (e.g., Hot-Dip Galvanizing).

Q: Can you accommodate third-party quality inspections?

A: Absolutely. We welcome third-party inspection agencies (such as SGS, TÜV, or Bureau Veritas) to inspect raw materials, welding quality, coating thickness, and packaging prior to shipment.
