High-Quality Frame of Steel Truss

In modern industrial construction, the frame of steel truss serves not only as a load-bearing element but also as a complete structural solution that enhances durability, reduces costs, and accelerates project timelines. With more than 18 years of experience in steel structures and construction mechanics, Truong Thinh Corp offers a comprehensive service package that includes design, fabrication, surface treatment, and installation. This integrated process helps investors minimize technical risks, increase project efficiency, and ensure the highest level of structural safety. All products are manufactured in accordance with ASTM 3834, JIS, and EN standards on advanced production lines, meeting the strict technical requirements of large-scale industrial projects both in Vietnam and overseas.

1. Structure of the steel truss frame

A standard steel truss frame system by Truong Thinh Corp consists of three main components: the top chord, bottom chord, and web members. All components are manufactured and coordinated to form a precise steel truss that ensures efficient load distribution throughout the structure.

• The top chord forms the uppermost part of the structure, primarily subjected to compression, and determines the roof slope.
• The bottom chord connects the two ends of the top chord, functioning under tension to maintain overall stability and balance.
• The web system is composed of vertical and diagonal members arranged in a triangular load-bearing pattern, effectively distributing loads and minimizing deformation.

Depending on specific technical requirements, Truong Thinh Corp designs various truss types such as Pratt, Warren, or Howe, suitable for a wide range of structures including factories, cold storage facilities, commercial centers, and civil buildings. All design parameters are precisely calculated using Tekla Structures and SAP2000 software, ensuring near-zero deviation throughout the fabrication and erection process.

2. Outstanding advantages of the steel truss frame

Truong Thinh’s steel truss frames are manufactured from high-quality alloy steels such as SS400, Q235, Q345, and ASTM A36/A572 — common structural grades known for their high load-bearing capacity and excellent tensile strength. The material’s yield strength ranges from 235 MPa to 345 MPa, while the ultimate tensile strength reaches up to 620 MPa, ensuring mechanical stability and long-term structural performance.

Thanks to advanced manufacturing technology, the product can withstand heavy loads, torsional stress, wind pressure, and vibration during operation. The average service life of each truss frame exceeds 30 years, even in high-humidity or coastal environments. Factory pre-fabrication significantly shortens on-site erection time, reducing overall construction duration by 30–40% compared to conventional reinforced concrete structures. With high design flexibility, Truong Thinh Corp can create various roof configurations to meet both aesthetic and functional requirements for each project.

3. Applications of the steel truss frame

Truong Thinh’s steel truss frames are widely applied across multiple construction sectors. In industrial projects, they are used for production plants, warehouses, power facilities, and logistics centers. In the commercial sector, the frames are ideal for shopping malls, showrooms, exhibition halls, and large-scale civil buildings. Thanks to their lightweight, high durability, and easy assembly, these truss systems are also a preferred choice for pre-engineered steel buildings (PEBs) — helping reduce construction costs and maximize land-use efficiency.

4. Manufacturing process of the steel truss frame at Truong Thinh Corp

The manufacturing process of the frame of steel truss at Truong Thinh Corp follows a closed-loop and strictly controlled system, consisting of three main stages: precise technical design, automated cutting and welding in compliance with international standards, and surface finishing through painting or hot-dip galvanizing. This ensures that every product is durable, aesthetically refined, and highly reliable.

4.1 Stage 1: Design

The design stage serves as the foundation for product quality. Truong Thinh Corp’s engineers use Tekla Structures, AutoCAD, and SAP2000 to simulate load distribution, verify stress and deflection, and optimize member dimensions according to international standards. Each drawing is cross-checked between the engineering department and the fabrication workshop using an internal checklist system, ensuring that all parameters are implemented accurately during manufacturing.

4.2 Stage 2: Automated cutting and welding

All input materials come with CO–CQ certification and are tested for mechanical and physical properties before production. The modern CNC Plasma cutting system achieves ±1 mm precision tolerance, ensuring consistent accuracy.

Automated Gantry welding technology, integrated with digital current control, produces uniform and robust welds that meet ASTM 3834 standards. After welding, each member undergoes ultrasonic testing (UT) to detect any internal defects in the joints, guaranteeing maximum safety and structural stability for the entire truss system.

4.3 Stage 3: Surface finishing and protection

After welding, all components are cleaned through shot blasting to the Sa 2.5 surface preparation standard. They are then coated with an Epoxy primer followed by a Polyurethane (PU) or two-component Epoxy topcoat. The total coating thickness ranges from 100–200 µm, enhancing corrosion resistance and durability under harsh weather conditions. For projects requiring higher endurance or located in coastal environments, Truong Thinh Corp applies hot-dip galvanizing with a zinc coating thickness of 80–100 µm, providing surface longevity of up to 20–30 years.

This workflow ensures close coordination between design, fabrication, quality control, installation, and the client, guaranteeing full quality assurance, international technical compliance, and 20–30% faster completion compared to traditional construction methods.

Step 1: Requirement analysis and technical consultation

Upon receiving project information, Truong Thinh Corp’s engineering team analyzes key technical parameters such as span width, roof load, material grade, foundation conditions, and structural standards. Based on these inputs, the company proposes an optimized steel truss frame solution, providing preliminary drawings, 3D structural simulations, and cost estimates, enabling clients to select the most suitable configuration for their project needs.

Step 2: Site survey and final design

Once the technical solution is approved, the survey team conducts on-site measurements to collect data on elevations, wind conditions, erection layout, and roof frame positioning. All data are processed using Tekla Structures, AutoCAD, and SAP2000 to simulate loads, stresses, and deflection across the truss system. Each drawing undergoes internal cross-checking through a QC checklist, ensuring a design tolerance of less than ±1 mm before moving into production.

Step 3: Manufacturing at Truong Thinh Corp’s steel structure factory

Once the design dossier is approved, fabrication begins at Truong Thinh Corp’s 25,000 m² steel structure plant. Materials include SS400, Q235, Q345, ASTM A36/A572 steels, all verified with CO–CQ certificates and mechanical tests prior to use.

Components are CNC Plasma-cut, Gantry-welded automatically, and shot-blasted to Sa 2.5 standard before painting or hot-dip galvanizing. Surface finishing options include 2–3 coats of Epoxy paint (100–200 µm) or hot-dip galvanizing (80–100 µm) depending on environmental conditions. Each component carries a unique QR code that allows clients to instantly access detailed information on material origin, production process, and inspection records.

Step 4: Transportation, installation, and handover

After completion, steel truss frame components are carefully packaged, protected, and transported to the site using certified 20–50 ton trucks and cranes. The Truong Thinh Corp installation team supervises the entire erection process, ensuring accurate positioning, alignment, and roof slope according to approved drawings.
Before handover, the structure undergoes mechanical testing, load testing, and acceptance inspection under ISO 9001:2015 standards, ensuring all technical specifications and structural safety requirements are fully met.

Step 5: Warranty and after-sales support

Upon project completion, Truong Thinh Corp provides a full as-built dossier, including material certificates, inspection reports, and detailed maintenance guidelines.
