Startabox® - Reinforcement Continuity System

The Startabox system consists of specially selected, high yield reinforcing steel, housed in a fully perforated and hot dip galvanised carrier unit. The unit ends are sealed to prevent the ingress of concret

The reinforcement used is CARES Approved and cut and bent to conform to BS8666. The system is assembled in a BS EN ISO 9001 factory environment and the full system carries a CARES Technical Approval.

The product design ensures fast and easy faxing by nailing to the formwork or tying to the existing reinforcement. Bars are quickly bent out using the specifically designed re-bend tool.

When compared to traditional methods, the product offers a cost saving by means of a less labour intensive installation process and a simplification of formwork.

Most joints in concrete, on many different types of construction site, have the potential to be formed using Startabox. Startabox has been supplied to high rise commercial buildings, water treatment plants, hospitals, prisons, energy from waste facilities and many more types of construction site.
