Continuous High Chairs

Lattice-type Continuous High Chairs (also known as rebar chairs, mesh spacers, or stools) are manufactured in-house and stocked in 2Mtr lengths at 50mm, 75mm, 90mm, 105mm, 135mm, 150mm, and 200mm heights. The main bars are 3.6mm steel bars.

These are supplied in packs of 25no. That means a total distance of 50Mtrs of high chairs (2Mtr x 25no) per pack.

Highchairs are designed to be economical, strong, and to prevent puncturing of DPM - a common issue with poorly manufactured stools. 

It is recommended to use 4no chairs for each sheet of Merchant size mesh (3.6Mtr x 2Mtr), and 5no chairs for Standard size mesh (2.4Mtr x 4.8Mtr). 

Continuous highchairs are used to ensure reinforcement mesh remains in place while concrete is placed and compacted. Their primary goal is to maintain a correct level of concrete cover, reducing the chances of corrosion and improving the reinforcing ability of the fabric to an optimum level.

Chairs also ensure an equal distance is maintained between reinforcement slabs, and are also commonly used in walls as spacers between components.

Continuous highchairs are essentially lattice cross-bars welded at set distances along 1-3 main lines of 3.6mm round bar.

Purchasing steel highchairs in this manner and to a predefined height means that the time spent on-site organising the placement on concrete slabs is significantly reduced. They allow for neater and more secure reinforcement mesh- protecting the rebar from accidental knocks or vibrations that commonly occur on-site

Additionally, having pre-built mesh spacers prevents any potential shortcomings arising from a lack in technical skill of employees handling the reinforcement materials.

In short, it’s quicker, cheaper, and more efficient ordering bar chairs pre-built.
