Yes. You can order individual components such as vertical standards, ledgers, diagonal braces, base jacks, steel planks, and accessories. This is perfect for replacing damaged parts or supplementing existing systems.
Q2: Are your components compatible with other brands?
Our ringlock parts are designed to be compatible with major international systems, including Layher and similar European standards. We also offer custom adapters if needed.
Q3: What materials do you use for different components?
We offer parts in various grades of steel such as Q235, Q345, and Q355, depending on load requirements. Surface treatments include hot-dip galvanizing, electro-galvanizing, or painting for corrosion protection.
Q4: Can I customize the sizes or specifications of components?
Absolutely. We support custom lengths, thicknesses, and special designs for components to match specific project needs.
Q5: What are the standard specifications for your vertical standard bars?
Our vertical standard bars typically feature a tube diameter of 48 mm with a thickness of 3.25 mm. They are constructed from high-strength Q345 material and treated with hot-dip galvanizing for optimal corrosion resistance.
Q6: What is the load capacity of the solid jacks in your system?
Both our Solid Base Jack and Solid U Head Jack are engineered for heavy-duty load support, capable of carrying a capacity of up to 8 tons.
