A comprehensive one-stop solution featuring fast delivery timelines
and expert installation guidance. This robust building structure
comprises precision-engineered internal support systems and durable
external enclosure components, forming a cohesive and reliable framework.
The steel framework employs a sophisticated portal frame design,
integrating:
- Heavy-duty steel columns
- High-strength load-bearing beams
- Reinforced bracing systems
When paired with the external enclosure, this configuration forms a
fully sealed building envelope engineered to resist extreme weather
conditions—including strong winds, heavy rainfall, and accumulated
snow loads—thus ensuring long-term structural durability and
reliability.
All metal components undergo meticulous prefabrication in our
specialized workshop, featuring precision cutting, welding,
drilling, and the application of industrial-grade protective
coatings.
Prefabricated components are transported to the construction site
and secured via standardized bolted connections, enabling:
- Streamlined on-site assembly with minimal on-site modification
- Labor-efficient installation processes
- A significant reduction in overall construction timelines
The stability and performance of the steel frame depend on five key
structural components working in synergy:
- Tension members
- Compression members
- Bending members
- Combined-stress members
- Purpose-engineered connection joints
Each component is precision-engineered to optimize load
distribution, ensuring the frame meets rigorous structural
performance standards.
Construction Features
- Lightweight construction with high strength, large spans, and
reduced foundation pressure
- Shorter construction period compared to concrete buildings with
simple on-site assembly
- 20-30% lower investment cost than traditional buildings
- High fireproof performance and corrosion resistance
- Buildings can be disassembled, moved easily, and recycled with no
pollution

Welding procedures:
TSIN undertake all welding procedures in accordance with GB
standard. Our dedicated Welding Inspectors are certified by the
government authority.
We perform non-destructive testing (NDT) in accordance with
contract documents and applicable welding codes. As part of this
process, we ensure that all inspections, test plans and quality
manuals are fully documented and maintained.
Tests we conduct include:
- Dimension check
- Visual examination
- Ultrasonic testing
Whether manufacturing a domestic structure, as well as industrial
building or commercial building, our precision fabrication reduces
time onsite and the associated labour costs.
At TSIN, we believe that the quality of our work is a defining
feature of our services. We are committed to providing exceptional
quality products and a service which is reflective of our
dedication to excellence at all stages of a project lifecycle.
We deploy extensive quality control measures to safeguard the
quality from beginning to end. This includes the inspections of all
materials prior to, and following fabrication.
TSIN employ highly trained and experienced professional fabrication
and welding staff, and because of this, we are able to deliver a
wide variety of fabrication services including a variety of steel
sections, designed to meet your specific project requirements.
