Frequently Asked Questions

Q: Why is hot-dip galvanization important for Keel Steel?

Hot-dip galvanization creates a thick, durable zinc coating that protects the steel from corrosion and rust, ensuring the structural integrity remains intact even in humid or outdoor construction environments.

Q: How does Keel Steel compare to traditional timber supports?

Unlike timber, Keel Steel offers significantly higher strength-to-weight ratios, does not warp or rot, and provides far superior stability under heavy pressure, resulting in a safer and more durable build.

Q: Can the lengths of the Keel Steel be customized?

Yes, our Keel Steel is available in lengths ranging from 600mm to 3000mm, with increments of 300mm to ensure a precise fit for your specific project dimensions.

Q: What is the typical application of structural metal products in this category?

These products are primarily used in structural metal manufacturing for reinforcement, scaffolding support, and high-load industrial frameworks where precision and strength are critical.

Q: How does the use of Keel Steel affect construction timelines?

Due to its standardized dimensions and structural design, Keel Steel allows for much faster installation compared to custom-cut wood, significantly accelerating the construction schedule.

Q: What is the weight specification for the standard 50703.0mm profile?

The standard profile has a weight of approximately 3.94 kg per meter, providing an optimal balance between structural rigidity and manageable handling on site.
