Speciality Finishes
One Rule Does Not Fit All...
Due to the wide range of environmental conditions and bespoke aesthetic requests, our standard finish ranges do not always fit the bill.
At Valmont® we constantly develop and bring to market new and improved corrosion protection systems, whether it be semi sheen product for architectural markets or extremely robust anti corrosion systems for coastal areas.
Whatever your requirement, Valmont® will have a solution. If you don’t see what you need, just ask.
Please contact us for further details on region specific finishing systems relating to the following items:
Marine Environment Finish.
A highly durable finish applied to galvanised columns to be located in or near marine (saline and corrosive) atmospheric conditions. System type: spray paint 2-pack glass reinforced epoxy finish is applied to the column, then followed by a polysiloxane finish to RAL, BS4800 or BS381C colours.
Required durability of system: No maintenance in first 10 years, minor maintenance between years 10 to 25, major maintenance after 25 years.
Polyester Powder Coat.
To form a polyester powder coating, only the paint solids are sprayed onto the product, in an atomised powder form. The powder is drawn to the product and adheres due to an electrostatic charge applied to the powder during spraying. The column is then heated to 200 degrees Celsius in an oven, forcing the powder to fuse to the product, forming a smooth, tough and resilient coating. This provides an even and durable finish over the galvanised steel surface. XXXX denotes customer RAL choice.
Required durability of system: Long life system with excellent weather-proof characteristics. Damaged areas cannot, however, be repaired due to the nature of the coating.
Glass Flake Root System.
A highly durable finish applied to galvanised column root. This system uses 2-pack glass reinforced epoxy giving excellent abrasion, saline and corrosive resistance.
Both external root only, and internal/external root options are available upon request.
Bitumen Root.
Black bitumen coating is applied to the external root of the column, to a height of 250mm above ground level (unless otherwise specified).
Benefits: Additional protection of the root against corrosion.
Anti-graffiti / Anti-fly Poster Coating.
This anti-graffiti non stick surface coating, when combined with a suitable cleaning technology, allows the removal of graffiti without altering the original surface finish. Applied as an integral part of a polysiloxane system to the section of the column most prone to Graffiti and Fly posters. The area of the column with this coating has a textured surface. The system is highly resistant to many different kinds of marker pens and aerosols, as well as providing a non-stick surface to deter fly posters, and offers a hard wearing surface finish.
Required durability of system: Long term life of 25-30 years. Available in RAL, BS4800 or BS381C colours.
G1 Root System.
A Highways England series 1900: 2014 specification, 2 pack epoxy m.i.o, applied to the external root section and returned internally around edges. A 3-coat (including mordant T-wash on galvanised surface), 275 micron dry flim thicknes painted root.
Required durability of system: No maintenance in first 8 years, minor maintenance from 8 years and major maintenance after 15 years.
