Manufacturer and Fabricator of Structural Steel I-beam

With over 18 years of experience in the design, fabrication, and erection of steel structures, Truong Thinh Corp is one of Vietnam’s pioneers in I-beam manufacturing. Each year, the company supplies tens of thousands of tons of structural steel for industrial plants, factories, warehouses, and commercial buildings both domestically and internationally. The I-beam is considered a core product, engineered for high load-bearing capacity, superior durability, and reliable delivery schedules that meet the most demanding technical standards of modern construction.

1. Types of I-beams supplied by Truong Thinh Corp

Truong Thinh Corp focuses on developing I-beam product lines suitable for a wide range of industrial applications, from manufacturing facilities to large-scale infrastructure projects. Among these, fabricated welded I-beams are the most popular due to their design flexibility and cost efficiency.

1.1 Fabricated welded I-beam

Fabricated welded I-beams are produced from hot-rolled steel plates that are cut, welded, and shaped automatically according to design drawings. Their greatest advantage lies in customizable dimensions for each project, helping reduce material costs for large-span structures; for projects that require a broader category overview or alternative profiles, see our factory’s full range of steel beam solutions.

Production is carried out using automatic gantry welding systems that ensure deep penetration welds, uniform seams, and excellent structural stability. This beam type is particularly suitable for heavy-load structures such as pre-engineered steel buildings, industrial plants, logistics warehouses, and bridge frames. With advanced facilities and proactive production capabilities, Truong Thinh Corp is able to meet tight project schedules without compromising quality.

1.2 Comparison between I-beam and H-beam

Criteria	I-Beam	H-Beam
Cross-section geometry	Taller web, narrower flange	Web and flange nearly equal
Bending resistance	Better under vertical loads	Better for multidirectional loads
Application	Main frames, floor beams, bridge girders	Columns, braces, multidirectional load frames
Weight	Lighter by approximately 10–15%	Heavier, higher material usage
Cost	More economical for large structures	Higher due to increased steel volume

2. I-Beam production process at Truong Thinh factory

At Truong Thinh’s steel structure plant, the entire I-beam production process is conducted in a closed system—from design and fabrication to inspection and finishing—following ISO 9001:2015 standards for quality control and precision.

2.1 Stage 1 – Design

The design phase forms the foundation of I-beam production. Truong Thinh uses Tekla Structures and SAP2000 software to simulate stress and deformation, determining optimal dimensions for load-bearing performance. Each drawing is cross-checked between the design and production teams using internal QA checklists to ensure accuracy, manufacturability, and safety.

2.2 Stage 2 – CNC cutting and automatic welding

After design approval, steel plates are processed through CNC plasma and oxy-gas cutting machines, ensuring high precision and minimal material waste. Welding is performed using automatic gantry welding systems, producing strong and consistent welds that comply with international standards. All input materials are verified with Certificates of Origin (CO) and Certificates of Quality (CQ) before entering production.

2.3 Stage 3 – Surface finishing and protection

Once structural assembly is complete, beams are shot-blasted to Sa 2.5 surface cleanliness to remove rust and contaminants. Depending on project requirements, the I-beam surface is coated with epoxy primer and polyurethane paint or hot dip galvanized for enhanced corrosion resistance. Each coating layer is thickness-tested and documented for long-term traceability.

3. I-Beam production capacity at Truong Thinh Corp

Production capacity is the key factor that determines the ability to handle large and complex projects. Truong Thinh Corp operates modern manufacturing facilities and a team of experienced engineers capable of meeting both high technical requirements and fast construction schedules.
