JIS A 5525 covers requirements related to fabrication work of Pipe such as: Material properties, Welding technology, Inspection of Pipe products, ...
2. Can we use Spiral Steel Piles instead of Concrete piles?
Yes. We can absolutely use Spiral Steel Piles instead of Conrete piles.
Moreover, Steel Piles with advanced features can perform higher horizontal resistance. As the result, Steel Piles are used in Port Facilities, Bridge foundations, High-rise buildings in Earthquake area.
3. Now, we designed Concrete bored piles for our project. However, the design length is too long for construction easily at site.
Can J-Spiral Steel Pipe support us in changing solution from bored piles to Steel Piles foundation?
Yes. We can support you in changing your design from Bored piles to Steel Piles foundation. Please send us your information related to your project.
J-Spiral Steel Pipe has been supported by JFE Steel (from Japan) which doing researches and application of Steel Piles foundation.
4. Can we send Inquiry via your website?
Yes. You can send your inquiry to us via our website by accessing the tab Inquiry and fulfill the given form.
We will check and feedback as soon as possible.
