Street & Flood Lighting Columns

Types of Column -

Stepped Tubular Steel

Now the most frequently used column for conventional street lighting because of the lower price, consisting of a constant diameter column shaft with a larger diameter base compartment. The change in diameter is achieved by means of a short taper, frequently known as the shoulder. The angle of taper varies for different manufacturers and processes. The majority of columns have a single reduction although there are examples of two or more.

Conical or Octagonal

A constant taper circular section or a folded sheet polygonal section, which can be a regular or irregular polygon, generally with eight sides are quite common and can perform better in high wind exposure areas. A circular section with a constant diameter base compartment and a variable diameter shaft is also available.

Types of Protection -

Hot Dip Galvanizing

Now the most frequently used corrosion protection system for steel lighting columns due to its sacrificial properties and its equal protection to the internal and external surfaces of a column. Galvanizing is carried out to BS EN ISO 1461. In the last ten years it is claimed that the life of the galvanized coating has doubled due to the reduction of airborne pollutants and the halving of the rate of loss of thickness.

Painting

There is a very large range of different painting systems that can be applied to bare steel, aluminium sprayed surfaces or galvanised surfaces. In coastal areas such painting can also further protect the galvanising from the continuous sea salt spray.

Root Protection

We recommend bitumen root protection or glass flake root applied to that part embedded in the ground and for 250mm above ground. This prevents corrosion, resist mechanical abrasion but also attack from electrolytes in the groundwater that can cause the material of the root to be conducted onto surrounding objects by electrolytic action. For particular soil types and for local authorities.

Definitions

Nominal Height

This is the height of the column and bracket combination from ground level to the axis at the point of entry into the luminaire at the luminaire fixing.

Bracket Projection

This is the horizontal distance from the vertical axis of the column to the point of entry into the luminaire at the luminaire fixing, frequently incorrectly called “outreach” which is the horizontal distance from the vertical column axis to the centre of the light source (used for lighting design). It is important to state if single arm, double arm or multiple arm brackets are required.

Flange Plates

The structural plate at right angles to the column axis at, or near, ground level to secure the column to a foundation or structure by means of foundation bolts, frequently incorrectly called “base plate” (see below).

Planting Depth

The length of column shaft below the intended ground level, known as the root, for embedment in the backfilled soil to provide stability to the column shaft.

Base Plates

An anti-sink plate at the bottom of the root of a column which may either be fixed to the column or supplied separately.
