Manufacturing and Processing High Quality Gusset Plates

In every steel structure, whether it is a factory, warehouse, roof truss, crane, or pre-engineered building, gusset plates may appear small but serve as essential connection points that ensure overall stability and effective load transfer between columns, beams, and braces. Produced on advanced CNC lines with high-quality materials such as SS400, Q235, and A36, and protected by epoxy coating or hot-dip galvanizing, Truong Thinh’s gusset plates offer exceptional precision, strength, and long-lasting durability for both domestic and international projects.

1. Applications of gusset plates

Before exploring the production process, let’s look at the role and applications of gusset plates in real-world structures. Understanding where and why they are used reveals why accuracy and quality are top priorities in every steel structure project. In modern industrial construction, gusset plates appear in most load-bearing connections. Depending on function, they may serve to connect, anchor, or transfer loads between key structural components.

In steel truss systems, gusset plates are used to connect bracing and load-bearing members, distributing loads evenly and preventing torsion. In large-scale projects such as bridges, factories, and pre-engineered buildings, they connect columns (H-beams), beams (I-beams), and Z-frames, ensuring uniformity and overall stability.

For heavy-duty structures like crane systems, deck floors, large canopies, or interconnected frameworks, gusset plates act as direct load transfer points between structural steel and foundations. High-quality plates help reduce vibration, prevent distortion, and enhance load-bearing capacity. Precision-engineered gusset plates also simplify erection, reduce installation time, and lower long-term maintenance costs—one reason why many contractors and investors choose Truong Thinh’s gusset plates for their projects.

2. Production process and quality control at Truong Thinh factory

To meet the stringent demands of technical precision, mechanical strength, and durability, Truong Thinh has established a fully controlled in-house manufacturing process comprising three main stages: design – fabrication – finishing, all compliant with ISO 9001:2015 standards.

2.1 Stage 1: Design – The foundation of accuracy

Every gusset plate starts with a detailed design drawing—crucial for ensuring dimensional precision and structural compatibility. Truong Thinh’s engineering team utilizes professional software including Tekla Structures, AutoCAD, and SAP2000 to model plate geometry with exact parameters: size, bolt-hole layout, thickness, and load capacity. Each drawing undergoes a cross-verification checklist between the design and production departments, helping detect errors early, optimize material use, and guarantee field-fit accuracy.

2.2 Stage 2: Automated cutting and welding – Precision to every millimeter

Once approved, production begins at Truong Thinh’s 25,000m² facility equipped with CNC plasma–oxy gas cutting machines, automated drilling and punching systems, maintaining tolerances within ±0.5mm. Steel plates are sourced from certified suppliers with CO, CQ documents, meeting ASTM 384 and JIS G3101 standards (SS400, Q235, A36 grades), with yield strength 245–355 MPa and tensile strength 400–510 MPa.

Fabrication includes cutting, drilling, stamping, and welding (for composite plates). All welds are executed using semi-automatic and robotic welding systems to AWS D1.1 standards, ensuring aesthetics, strength, and reliability.
Finished products undergo mechanical testing, flatness and squareness verification, and dimensional inspection using specialized gauges. Non-conforming parts are reworked or rejected before proceeding.

2.3 Stage 3: Surface finishing and protection – Strength meets aesthetics

After fabrication, plates are shot-blasted to Sa 2.5 surface cleanliness with roughness Ra 15–50 μm.

Depending on project requirements, plates are finished by:

• Two-layer epoxy coating with total thickness 80–100 μm, customizable by RAL color; or
• Hot-dip galvanizing with zinc thickness 80–100 μm, providing 10–15 years of outdoor corrosion protection.

All products undergo final quality control (Final QC), including coating thickness, adhesion, and visual inspection, before being labeled, packaged, and shipped.

3. Manufacturing capacity at Truong Thinh

To ensure consistent quality and fast delivery for hundreds of projects annually, Truong Thinh continuously invests in state-of-the-art technology, skilled manpower, and a robust quality management system.
