Frequently Asked Questions

Ask Us More
  • What types of projects use specialised welding?

    Specialised welding is commonly used in high-stress or high-performance applications such as pressure vessels, load-bearing frames, automotive modifications and equipment repairs. It’s also essential when working with stainless steel or dissimilar metals, where standard welding may not provide a strong or corrosion-resistant join. The method chosen depends on material type, intended use and access to the area being welded.

  • Why use precision machining for one-off parts?

    Precision machining is ideal for one-off components because it delivers consistent accuracy and surface quality, even without mass production. This is particularly important when replacing damaged parts that no longer exist or when building a prototype. The process allows for tight tolerances, which improves fit and function—especially in systems with moving parts or high-pressure requirements.

  • What are screw piles best suited for?

    Screw piles are most often used for building foundations where speed, access and soil conditions make traditional footings less practical. They are ideal for decks, sheds, boardwalks and retaining walls. Their installation causes minimal site disturbance and they can be removed or adjusted easily, which makes them a flexible solution for both permanent and temporary structures.
