Startabox/Continuity System

Startabox® - Reinforcement Continuity System

The concept and use of reinforcement continuity strip systems or ‘pull-out bar’ systems has been widespread in Europe and further over the last 30 years, and is a widely accepted means of providing reinforcement continuity across construction joints in concrete. The system utilises the concept of overlapping reinforcement to provide a connection.




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.

Startabox® - Standard Reinforcement Continuity System

Although most Startabox units are made to order using the engineers original rebar details, there are occasions when time pressures do not allow this and a quicker supply is required. Last minute drawing changes or rescheduling of pour sequences can require another solution.

For this reason, a full range of Startabox standard units are kept in stock for rapid dispatch. The range covers a wide variety of wall and slab thicknesses and caters for the most popular bar diameters and bar centres. Standard units can be easily ordered using the relevant stock code below.

  • Standard units containing 12mm rebar are supplied with 500mm lap bars.
  • Standard units containing 16mm rebar are supplied with 650mm lap bars.
