Quick Overview

Introduction

Euro Accessories are the sole distributor in the UK and Ireland for BAG Column Formers. BAG have more than twenty year’s experience in the manufacture, design and delivery of Column Formers throughout Europe, making them the market leader in this sector.

Lined

Lined BAG Column Formers are fitted with a PVC internal liner running the entire length of the column tube, providing a smooth blemish free surface. Lined Column Formers will only leave a hairline seam on the surface of the finished column corresponding to the joint line of the formwork lining material.

Unlined

Unlined BAG Column Formers are ideal for applications where surface finish is not critical. They leave a spiral joint line on the surface of the finished concrete.

Flat Profile

BAG can supply square or rectangular Column Formers on request. These are manufactured from the standard circular former with an additional polystyrene insert manufactured to your specific flat column dimensions.

Bespoke

BAG offer made to order bespoke designs for diameter, surface finish and shape. Please contact our sales team for further details.

Water Resistant

Due to the manufacturing process and the outer foil membrane used in the BAG Column Formers they are resistant to humidity and water ingress.
