PIllar materials


One of the most commonly used materials for feeder pillars is galvanised steel. These units are typically produced in either 3mm or 5mm mild steel. Thicker 5mm steel is generally reserved for larger cabinet applications or for use in highway infrastructure, where greater strength and durability are required. Once fabricated, these steel units undergo a process known as hot dip galvanising. This involves immersing the steel in molten zinc, which forms a robust, protective layer against corrosion. This galvanising process conforms to BS EN 1461, a recognised standard that ensures consistent and long-lasting protection. With appropriate environmental conditions and installation, a hot dip galvanised steel feeder pillar manufactured by Haldo can offer a design life of up to 50 years. In addition to corrosion protection, the galvanised finish also provides an excellent base for further painting, should an aesthetic or corporate colour finish be required.

Stainless steel is another highly effective material used in the manufacture of feeder pillars, particularly in coastal or high-salinity environments where salt corrosion poses a significant threat. Unlike mild steel, stainless steel does not require galvanising and is inherently resistant to rust. Haldo offers stainless steel cabinets in various grades to suit different project specifications, whether the requirement is based on visual preferences or challenging environmental conditions. Stainless steel cabinets can also be painted if a specific finish is desired, making them an ideal solution for larger or more prominent installations where appearance is important alongside functionality.

Glass-reinforced plastic (GRP) is an alternative material that offers excellent performance in situations where weight or cost constraints make steel less viable. GRP cabinets are particularly advantageous for very large or deep installations, thanks to their high strength-to-weight ratio. GRP does not rust, is inherently corrosion-resistant, and is also electrically non-conductive, offering a high level of safety. These qualities make GRP kiosks and cabinets a practical and efficient option for many electrical and infrastructure applications.
For compact applications, Haldo’s mini feeder pillars are typically manufactured from 3mm mild steel and include an integral root for ease of installation. These are also hot dip galvanised for long-term protection, offering a durable and low-maintenance solution in a smaller format.

In summary, the selection of the appropriate feeder pillar material should be guided by the intended use, environmental conditions, and practical requirements of the installation site. Galvanised steel, stainless steel, and GRP all provide distinct advantages, and Haldo is able to offer each of these materials to meet a wide range of project needs.
