Steel Profiled Cladding Sheets

Thomas Panels and Profiles is one of the largest manufacturers of metal profile sheeting in the UK, offering a wide range of panels and profiles to suit every roof and wall application.

Main Features

Lasts for years
Relatively straight forward to install using simple tools
Available in a choice of colours and finishes and orders can be tailored to your requirements

Steel profiled sheets are adaptable too, so when a thermal barrier is needed to prevent condensation (eg when the air inside the building is warmer than outside, anti-condensation fleece can be applied to the underside of the sheet.

Our Vent Air sheets can act as a great aid for buildings whereby sound pollution is an issue, Talk to Thomas to see how this can benefit your build.

How is it made?

We manufacture sheets from coil of flat coated steel which are processed through a roll forming machine, putting in the profiles (or pattern) and giving the sheet its strength. We can make almost any length of sheet from 500mm to 9000mm plus, the only limiting factor for length is transportation and handling of very long lengths.
Being able to select the exact length you require means that joining sheets down the run of the roof are a thing of the past!
Tile effect sheeting goes through a brake-press to form the tile look, but as with other profiles - it all starts from the same base material.

Colours and coatings

Under the top coat of polyester and plastic finishes, all material undergoes a number of base coatings before galvanising and is then top coated. As they are most popular, we carry the standard range of colours which are selected to blend into the surroundings with many more colours available. If you, or your customer require a specialist colour, we can coat to a Ral number but that may have a price and lead time implication. There are differing tolerances for the coatings, we can advise on the most suitable one for your project.

TPP Plastisol

TPP Plastisol is a coated steel product specifically developed by Thomas to offer excellent lifetime performance at a competitive price.

This is a more robust finish than polyester and it it always specified on projects where a guarantee of life span is required. Many cladding contractors prefer using this tougher finish as it makes for easier fitting. We would expect 15-25 years, though we believe this could be far longer.
N.b. The coating manufacturers lifespan guarantee is conditional upon ongoing treatment and cleaning.

TPP Polyester

TPP Polyester is a steel coated product which has been developed for aggressive demands of the industrial sector.
Overall a polyester or painted finish is a cheaper option than plastic coated and while there is no official guarantee on this product, our experience shows that this product is long lasting.
Factors affecting its useful life expectancy include
Proximity to the coast
Physical damage (from over hanging branches etc)

One huge benefit is that after x number of years, if the finish needs attending, its a simply a matter of a coat of paint.
Polyester sheets need careful handling during fitting as the colour coat can easily be scratched. If this happens, the base coat will still be providing protection from the elements and touch up paint can be applied.

We have carefully selected our high-build polyester in a range of colours to harmonise with different industrial environments. This results in a product which offers excellent aesthetics and a lifetime performance at a competitive price.

Which Profile?

With over 300 box profile and corrugated patterns available, there is plenty of variety! But unless you are specifically matching an existing sheet (ie if you need to fit them 'end to end' to extend the run of the roof), the actual profile you use is not usually critical. Most are described by the coverage the sheets gives when lapped side by side, usually 1000mm and the height of the bump or profile, say 32mm. So this profile is known as 1000-32. Many of the patterns vary slightly from each other (due to variations of roll forming machinery between manufacturers). Our range means we will have something suitable for you even if your requirements are of a specialist nature.
Where an absolute match is required, with our knowledge of profiles, we offer an identification service. All we need is a trace on paper of the profile and some basic measurements. Please call for more details.
