A. Production Information

GSteels welded beams and welded columns are produced using steel plates to form a web and two flanges.

Gsteels welded beams and columns are welded using complete penetration submerged automatic arc welding. Single or double sided welding can be done depending on customer requirements. 


B. Advantages

Gsteels welded beams and welded columns provide several key advantages to customers.

1. Infinite Design Options

Subject to your application, our fabrication limitations and availability of plates according to your thickness and tensile requirement, you have the flexibility of choosing, the height width, depth, thickness of web and flange to suit your needs.


2. Weight Advantage

Gsteels welded beams also provide a weight advantage from hot rolled beams and columns as the plates used in welded beams can be picked to suit your weight requirements and therefore translate into cost advantages. 


3. Cost Advantage

Gsteels welded beams also provide a cost advantage as the beams are designed and built in locations where cost of production are lowest.


4. Assurances of Quality

Gsteels welded beams and columns are produced in adherence to internationally recognized standards such as AS/NZS 3679.2:1996, which specifies requirements for welded I sections for general structural and engineering functions.

Depending on customer requirements Gsteels welded beams are supplied with several test reports to ensure that the welded beams meet strict quality standards. Among the test reports we can provide include.

  1. Non Destructive Testing Report
  2. Radiographic Testing Report
  3. Magnetic Particle Testing Report    
  4. Hardness Test Report
  5. Metallography Test Report
  6. Mechanical Testing Report
    1. Tensile Test
    2. Impact Test
    3. Bend Test
    4. Hardness test
  7. Compliance Report.
