04. Hollow Vertical Bar Railings

Hollow tube vertical bar railings from Zaun are increasingly popular in many settings and are ideal for use in settings that require a traditional, long-lasting boundary fence system. Hollow vertical bar railings are larger in diameter than the equivalent weight solid bar and have a heavier visual impact.

Typically available in heights from 1m to 2.4m, other heights are available upon request. These bigger tubes give similar strength to smaller solid bars and are well suited to areas where appearance is a priority. Using a round or square section tube, the vertical bar railings are flat-topped as standard but can be mitred for an attractive effect. Bar size increases with the height of the fence to comply with BS 1722 Part 9.


Hot-dip galvanised to ISO1461 & optional polyester powder coated, after stringent cleaning & treatment to give a well-adhered coating with a minimum of 60 microns.

All Zaun posts/panels/gates and painted auxiliary components (for example, clamp-bars, slide bolts etc.) benefit from a protective zinc layer and electrostatically applied polyester powder coating to BS1722 p16. Care is taken with pre-treatment to ensure sound adhesion between the zinc and paint layers. In a UK C1 environment, as defined in ISO 12944 p2, this should ensure a useful life expectancy of the fence of at least 15-20 years. Life expectancy in all environments can be extended by maintaining the fencing with regular washing. Useful life will be reduced if the fencing is damaged. Any coating damage should be repaired to reduce the effect on useful life.

Enhanced painting systems such as marine coatings are also available for improved life expectancy in C2-C5M environments.
