Mechanical Performance in the Outstanding:
The H-beams in Grade 300, 350 and 350L0 provide various yield strengths for different design requirements. They consistently perform in extreme load, wind, and seismic environments. To ensure structural safety and stability, at the same time, they also support optimized lightweight design, so as to reduce the whole cost of project.
Excellent Weldability & Fabrication Performance:
On account of excellent weldability, the H-beams can be welded both manually and automatically. The strength of dryer welds are similar to that of the base material which reduces welding defects, increases structural integrity and leads to improved constructability during on site work.
High Durability & Corrosion Resistance:
The products have high corrosion resistance after advanced surface treatment such as hot-dip galvanizing and anti-corrosion painting etc. They can be used in the tough environment of Australia and New Zealand, such as coastal and high humid regions, to improve the service life and to prevent maintenance costs.
Broadly Application Tolerance:
The structural H-beams find extensive application in the construction of bridges, industries, warehouses, multistory buildings and houses. They can also handle light, medium and heavy-load applications and are designed and tested to meet the requirements of today's and tomorrow's engineering needs in Australia and New Zealand.
Flexible Customization Services:
We are capable of providing customization Non-standard specifications, customized cutting length and surface treatment service as per project requirements, to meet requirements of various engineering and design from one-stop service.
