Every Holding Down Bolt Deserves a Centraliser

Easy-to-use, 100% Accurate & will save your Project Time & Money!

Our Story

Our Story

Development for Centraliser began in 2012 with a goal to improve the efficiency of Holding Down Bolt installation for large Structural Steel Framed projects. Utilising 35+ years of Civil Engineering experience across 100’s of projects, Satish Karra, the Founding member of Centraliser, has revisited an age-old question to answer, ‘Can the use of traditional methods for the assembly and installation of Holding Down Bolts be simplified?’ - the answer is yes! 


Centraliser integrates a simplified idea to an over complicated process during the Assembly and Installation of Holding Down Bolts throughout the early stages of foundation construction.

Why Centraliser?

Introducing Centraliser: Your Ultimate Solution for Precise Bolt Positioning in Construction

In the construction industry, the accurate positioning of Holding Down Bolts has long been a challenge, often leading to difficulties in remedial works on Concrete and Structural Steel Base Plates when bolts are cast incorrectly. This persistent issue not only consumes valuable time but also incurs unnecessary costs.

During the concreting process, the shifting of cones consumes the bolts' movement tolerances, exacerbating the problem. The result? Increased expenses and delays during remedial works to rectify the misalignment.

Enter Centraliser, the game-changer that guarantees 100% centralisation of Holding Down Bolts during the assembly and placement of Bolt Boxes in concrete foundations. By utilizing Centraliser, you can save significant amounts of time and money while simultaneously enhancing the overall quality of your project output.

By incorporating Centraliser from the outset, you can witness a noticeable reduction in labor costs and an increase in productivity. The inclusion of Centralisers in the Cone provides you with the assurance that Holding Down Bolts will remain centrally positioned within the Cone as they are embedded in the wet concrete. Additionally, the strategic placement of Centralisers in the Cone enhances the structural rigidity, minimizing the risk of Cone Collapse in the concrete.

Centraliser is not just a product; it's your guarantee of increased and consistent success in all your building projects involving Holding Down Bolt Boxes. Embrace Centraliser today and gain the competitive advantage that sets you apart from the rest. Experience effortless bolt positioning, cost savings, improved efficiency, and superior project outcomes with Centraliser by your side.

"When I first heard of the Centraliser, I admit, I did dismiss it as another 'gimmick'. But from the initial phone call with Satish and his visit to site to show us the product worked practically; I have quickly changed my mind."

We used the Centraliser on our project in Kettering for the Buckingham Group, with fantastic results. The waxed cones stayed rigid during installation, resulting in perfectly lined bolts, after stripping the templates the Centraliser was then replaced back onto the bolts until the steel frame was erected, stopping any potential debris entering the bolts void."
