Steel Structure buildings are the largest sector of the global industrial construction market, representing upwards of 70% of total activity. These buildings are typically used for workshops, factories, industrial distribution warehouses, retail, and leisure. Sizes vary from small workshops of just a few hundred square meters up to massive distribution warehouses covering over one hundred thousand square meters.
The following overall design requirements are essential at the concept stage for industrial buildings:

Portal frames typically use hot-rolled beams and columns. They are the predominant form of single-storey construction due to their efficiency in spanning wide areas with flat or pitched roofs.
Ideal for very large spans (greater than 50m) or facilities requiring heavy plant equipment suspended from the roof. Trusses offer high stiffness and modest deflection.
Compliance with AWS D1.1, AWS D1.5, AS/NZS, and EN-1090 welding standards.

Our fabrication follows rigorous international standards including AWS D1.1, EN1090, ISO, and AS/NZS to ensure structural integrity and safety.
Yes, every building is designed based on the specific environmental conditions of the site, including maximum wind speed, snow load, and seismic requirements.
We offer high-quality painting, hot-dipped galvanizing, and powder coating to protect the steel against corrosion and ensure long-term durability.
We provide professional design services to help optimize your project requirements and provide accurate structural layouts at the initial stages.
We perform Non-Destructive Testing (NDT), size checking, and fillet weld inspections during the fabrication process to ensure all welds meet specified safety standards.
We primarily use high-strength steel grades such as ASTM A572 Gr50, S355JR, Q235B, and Q355B, depending on the design load and structural needs.
