Expert in High-Precision Steel Structure Fabrication and Export- QSB Steel

In the modern construction and steel fabrication industry, QSB Steel is a trusted manufacturer specializing in high-quality steel structure fabrication, erection, and export for industrial and commercial projects worldwide.
With state-of-the-art factories, automated production lines, and a team of internationally experienced engineers, QSB Steel has the capability to fabricate large-scale and complex steel components with high precision, meeting global standards such as ISO, AWS, ASTM, and AS/NZS.

1. Built-up Beams and Crane Beams

Built-up beams are fabricated from welded steel plates, offering high load-bearing capacity and optimized material use according to design requirements. They are key structural elements in industrial plants, warehouses, logistics centers, and pre-engineered buildings (PEBs).
QSB Steel applies SAW automatic welding technology and ultrasonic testing (UT) to ensure weld quality, dimensional accuracy, and consistency.

Crane beams are specially designed to handle dynamic crane loads, requiring superior rigidity and stability. QSB Steel fabricates these beams under strict deformation control, achieving ±2mm installation accuracy, compliant with international crane standards.

2. I-Beams, H-Beams, and Purlins

QSB Steel supplies I and H beams in various sizes — from standard hot-rolled sections to custom welded built-ups. These are essential load-bearing members in steel buildings, mezzanine floors, bridges, and high-rise frames.

C and Z purlins are produced from hot-dip galvanized steel, offering excellent corrosion resistance, lightweight design, and easy installation. QSB Steel’s purlin system ensures stability and strength for roofing and wall cladding structures.

3. RHS/SHS, Channels, and L-Angles

Rectangular and square hollow sections (RHS/SHS) are ideal for frames, bracings, and architectural steelwork. QSB Steel ensures uniform wall thickness and precise dimensions to meet project specifications.

Channels and L-Angles are fabricated using CNC cutting and precision bending technology, ensuring high compatibility in installation. These components are commonly used in secondary framing and support systems within steel structures.

4. Pipe Racks and Kingposts

Pipe racks are critical structures in chemical plants, refineries, pharmaceutical, and energy facilities. QSB Steel designs and fabricates pipe racks with modular assembly, uniform load distribution, and ease of maintenance.

Kingposts enhance roof stiffness and load-bearing capacity in large-span structures. Using automated beam welding and laser inspection systems, QSB Steel ensures minimal fabrication tolerance — suitable for high-precision projects.

5. Handrails, Gratings, and Steel Stairs

QSB Steel fabricates handrails, gratings, and stair systems tailored to specific project requirements, ensuring industrial safety and aesthetics.
From hot-dip galvanized floor gratings to custom helical stairs, all products comply with international safety, load, and design standards.
The company also specializes in large or spiral stair structures, combining steel, stainless steel, and glass for premium commercial and architectural projects.

6. Hot-Dip Galvanizing and Surface Finishing

QSB Steel operates a large-capacity hot-dip galvanizing system, protecting steel components from corrosion in harsh environments.
Depending on project specifications and climate conditions, products can also be epoxy-painted, anti-rust coated, or powder-coated for optimal durability and aesthetics.

7. Auxiliary Steel Components

QSB Steel provides a full range of auxiliary structural elements such as tie rods, sag rods, connection plates, and high-strength bolts.
Even the smallest parts are fabricated with high precision, contributing to the overall stability and safety of the steel framework.

8. Capability in Complex and Large-Scale Steel Fabrication

One of QSB Steel’s core strengths is its ability to fabricate complex, large-scale steel structures with special technical requirements.
All products undergo dimensional inspection, NDT, load testing, and are shipped with material certificates, meeting stringent export standards for markets including Australia, Malaysia, the Philippines, and Japan.
