Finishes & Colours
Steel Work Finishes
Hot Dipped Galvanizing
– to BS EN ISO 1461:1999 This treatment offers a low maintenance, long lasting finish for all types of environment. It is dull silver in appearance.
Polyester Powder Coating
Powder coating has excellent outdoor exposure qualities, as well as offering an attractive consistent appearance in a variety of colours.
The importance of the finish is not only the visible top coat, but, equally, the pre-treatment of the steelwork. All Apex products are shot blast to SA2.5 to degrease the surface and provide a key for the subsequent processes. The steel is then etch primed with Zinc Phosphate anti-corrosive Primer then the final coat of Polyester Powder is electrostatically sprayed onto the surface to a thickness of 80 - 110 microns. The treated steelwork is then heat-cured, melting the Polyester Powder into a continuous phase and bonding it into the steelwork. Polyester Powder Coating provides a high durability and high resistance to weathering plus excellent colour stability.
Colour Chart
There are 8 standard colours to choose from.
Alternative BS or RAL Colours can be provided but they will incur an additional charge.
If requested, goods can be polyester powder coated on top of the galvanized finish to give a more durable resistance in extreme weather conditions. This does give the products a rougher texture than the standard powder coating due to the galvanized undercoat.
Roofing Materials
5mm Transparent PET
These high quality sheets are solid plastic manufactured from Polyethylene Terephalate (PET). They are extremely impact resistant and have an excellent fire rating complying with BS 476:Part 7. Their resistance to weathering is guaranteed for 10 years. They have a high chemical resistance so even graffiti can be removed using an acetone free solvent cleaner. PET is environmentally friendly with ideal re-cycling properties.
Plastisol Coated Steel
Plastisol cladding (HP200®) offers excellent resistance to corrosion and moderate weather resistance. Guaranteed for a minimum of 10 years, it presents a hard wearing option available in 6 standard colours:-
The reverse of the plastisol sheet comes as standard in a grey polyester. The exposed face is supplied in a 200 micron external grade PVC coating. The sheeting is non combustible and will not contribute to a fire. The roofing sheets achieve a Class 0 rating in the Building Regulations.
