Finishes & Colours

Steelwork finishes

Hot dipped galvanising – 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 – has excellent outdoor exposure qualities, as well as offering an attractive, consistent appearance in a variety of colours. The finish depends on more than the visible top coat: 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 a zinc phosphate anti-corrosive primer, and 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, for high durability and resistance to weathering with excellent colour stability.

If requested, goods can be polyester powder coated on top of the galvanised finish to give more durable resistance in extreme weather conditions — this gives the product a rougher texture than standard powder coating, due to the galvanised undercoat.

Colour options

There is a wide range of canopy and shelter colours to choose from. If you require a colour we don’t stock as standard, this may incur an additional charge — alternatively we can match your required colour to the nearest stock BS or RAL colour.

Roofing materials

5mm transparent PET – these high quality sheets are solid plastic manufactured from Polyethylene Terephthalate (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 recycling properties.

Plastisol coated steel – Plastisol cladding (HP200®) offers excellent resistance to corrosion and moderate weather resistance, guaranteed for a minimum of 10 years. The reverse of the 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.
