ComFlor® – Durability

When designing your ComFlor® steel floor decking you need to consider the environment that the deck will be exposed to. 

 

Is it a dry internal office or is it a car park open to the weather, or maybe you are looking at leaving the deck exposed for aesthetic or cost saving reasons. Each of these scenarios may require a different coating option for your chosen ComFlor® profile.

Offices – For internal dry environments the ComFlor® MZ140 

 finished decking would be the most cost-effective coating option, available for all our ComFlor ® profiles. MagiZinc® is an innovative Zinc Magnesium coating replacement for conventional galvanised steels. By adding and blending Magnesium and Aluminium into the Zinc coating, Magizinc® gives a superior performance over standard galvanised coated decks resulting in longer expected life.

Car Parks – for semi aggressive environments that car parks can be subject to, like windblown rain and exhaust fumes, an even more durable coating is required. ComFlor® MZ310 is another MagiZinc® finish that is designed for such challenges and is available with a guarantee of 25 years in environments up to and including C3. with the added benefit that you can still ‘through deck’ weld the shear studs. ComFlor® MZ310 is available for our complete ComFlor ® profile range.

Exposed Decks – a cost effective aesthetically pleasing option for the ComFlor ® 51+, 60 and 80 profiles is to go with the new FD+ finish and leave the underside of the deck exposed. ComFlor® FD+ composite steel floor decking with Colorcoat Prisma® has been developed and optimised for floor deck applications. The FD+ finish, as standard, is white on the exposed underside, both reflecting available light and providing an aesthetic finish. The topside of the deck has a galvanised finish where the concrete will be laid. 

If you are looking for a deck that can cope with aggressive environments then the ComFlor® FD+ composite steel floor decking with Colorcoat Prisma® is the product to choose, with a guarantee of up to 20 years in a C5 environment, making it ideal for decks in exposed coastal situations or for floors above swimming pools.
