Steel Structure Building
CNC Cutting – Accuracy ≦ 0.5 mm
Our advanced CNC cutting system ensures stable, high-precision material processing with a tolerance of within 0.5 mm. With optimized tool paths, automated calibration, and real-time monitoring, the cutting process delivers clean edges, consistent dimensions, and excellent repeatability. This level of accuracy is ideal for complex geometries, prototype fabrication, and mass-production components requiring reliable dimensional control.
CNC Punching – Accuracy ±0.01 mm
The CNC punching line is engineered for ultra-fine precision, achieving an exceptional tolerance of ±0.01 mm. High-speed servo control, rigid machine structure, and intelligent positioning technology allow us to create intricate hole patterns, slots, and custom shapes with micro-level accuracy. This ensures perfect alignment, uniform aperture quality, and dependable performance even for high-density or multi-step punching operations.
Automatic Submerged Arc Welding – High Accuracy and Double Efficiency
Our automatic submerged arc welding (SAW) system delivers exceptional welding precision and outstanding production efficiency. By utilizing continuous wire feeding, stable arc control, and full-coverage granular flux protection, the process achieves high-accuracy weld seams with excellent penetration and minimal spatter.
Compared with manual or semi-automatic welding, the automated SAW line can double overall efficiency, ensuring faster welding speeds, consistent bead profile, and uniform mechanical strength across long joints. This technology is ideal for large-scale structural fabrication, heavy-duty steel components, and applications requiring superior weld quality and high throughput.
100% Oxidative Removal Shot Blasting – Complete Rust-Free Surface Preparation
All steel members undergo a 100% oxidative-removal shot blasting process, ensuring that every surface is thoroughly cleaned and restored to its original metallic state. High-velocity steel shots effectively remove rust, mill scale, welding slag, oil residues, and surface contaminants, achieving a uniform profile that meets international surface preparation standards.
This deep, full-coverage treatment ensures no residual rust and significantly improves coating adhesion, corrosion resistance, and long-term structural durability. By delivering consistent surface quality across every steel component, the process enhances product performance and reliability in demanding industrial environments.
CNC Assembly – Accuracy ≤ 0.5 mm, Speed up to 2 m/min
Our assembly process is fully supported by CNC-controlled positioning and alignment systems, ensuring a maximum dimensional deviation of within 0.5 mm throughout the entire structure. Automated clamping, precision measuring sensors, and digital calibration allow components to be assembled with high repeatability and consistent geometric accuracy.
Certified Welding Team – Qualified by the State Administration of Work Safety (CWB)
All welders in our facility are fully certified by the State Administration of Work Safety (CWB), ensuring they meet national industrial standards for safety, welding technique, and quality assurance. Their professional qualifications guarantee stable arc control, uniform weld formation, reliable penetration, and compliance with stringent engineering requirements for long-term structural performance.
Foaming Roof with Patent Protection – Load Capacity up to 1000 N/sqm
Our roofing system adopts a patented foaming structural design, providing superior thermal insulation, acoustic performance, and long-term weather resistance. The closed-cell foam core is evenly distributed through high-pressure injection technology, forming a rigid, lightweight composite layer that maintains excellent dimensional stability under extreme environmental conditions.
With a certified load-bearing capacity of up to 1000 N/sqm, the foaming roof is engineered to withstand wind pressure, snow loads, and mechanical maintenance loads commonly encountered in industrial and commercial applications. Its enhanced structural strength ensures no deformation, no collapse, and reliable performance over long service life cycles.
Using Grade A waterproof CNC cutting technology, our wall panels achieve precise, clean, and visually refined edges. The production line is equipped with a robotic welding and assembly unit delivering 4–5× higher efficiency, maintaining a stable accuracy of ±0.5 mm throughout the process. With 100% weld seam pass rate and a production capacity of up to 60 units per hour, the system ensures high-quality, high-speed, and reliable manufacturing performance for every project.
All our wall and roof color steel sheets use aluminized primer and multi-layer polyester staving varnish, providing a durable finish with a service life of up to 15 years. The entire structural frame is hot-dip galvanized and coated with zinc-rich epoxy paint for enhanced corrosion resistance, using high-strength Q345 steel to ensure long-term stability. The system features organized surface drainage, capable of efficiently collecting rainwater in arid regions while preventing leakage issues. Container house beams also adopt high-strength galvanized Q345 steel, improving overall structural lifespan and achieving 35% steel savings through optimized engineering design.
Light Gauge steel building
Advanced Alu-Zinc Coated G550 Frame with ±0.5 mm Accuracy
The frame is designed using New Zealand CAD standards, enabling precise automatic bending, cutting, and punching with a consistent accuracy of ±0.5 mm. All structural components are manufactured from G550-AZ150 high-strength steel, featuring a full aluminized zinc (Alu-Zinc) protective coating for superior corrosion resistance, long-term durability, and stable performance in harsh environments.
Integrated Modular Light Steel System for Faster On-Site Installation
The light steel keel adopts a C + C combined structure, providing higher rigidity and improved load distribution for modular buildings. All wall cladding panels are manufactured entirely in PTH, ensuring consistent quality and precise fitment. The modularization process in PTH includes pre-assembling the steel structure, installing the wall cladding, and pre-setting the electrical and plumbing pipelines, allowing the modules to arrive on site in a nearly finished state. This greatly simplifies on-site work, reduces installation time, and enhances overall construction efficiency while maintaining stable structural performance.
