Liner sheeting forms an essential part of built-up wall and roof systems, providing the internal face of the building envelope while supporting insulation and external cladding. Designed for both performance and appearance, liner sheets create a clean internal finish while contributing to the overall structural and thermal efficiency of the system.
Suitable for both over-rail and under-rail applications, liner sheeting offers flexibility in system design to suit a wide range of building requirements. Over-rail systems allow for continuous insulation layers, helping to reduce thermal bridging, while under-rail applications provide a practical and cost-effective solution for many standard constructions.
Manufactured from high-quality steel and available in a range of profiles, liner sheets are designed to integrate seamlessly with insulation systems and external cladding, ensuring reliable performance across industrial, commercial, and agricultural buildings.
Coatings and colours: to suit every application
We offer a wide range of coatings and colours across our full product range. Options include galvanised, polyester and plastisol finishes, each with its own benefits and lifespan. For full details of available colours and specifications, please visit our website or speak to our team.
GALVANISED COATING
We use a high quality base steel for all of our manufactured products. This is then hot-dip galvanised with a Z275g/m² coating to ensure longevity of the foundation material.
You can expect sheets and flashings of this material to last approximately 10 years. This galvanised base layer is available in a range of thicknesses depending on the requirement.

Galvanised
POLYESTER
Polyester coated materials use the same Z275 galvanised substrate and alkyd primer as the plastisol materials but are then coated with a 25μm Polyester paint.
Mostly used in agricultural applications due to the complimentary colour range and stability in non-aggressive environments. This coating can be expected to last up to 10 years before first maintenance isrequired if properly maintained this time can be extended.

TPP Plastisol and TPP Plastisol +
TPP Plastisol and TPP Plastisol + are coated steel products developed by Thomas Panels and Profiles to deliver dependable performance for roof and wall cladding applications. Both systems are designed to provide a consistent finish, strong corrosion resistance and a practical solution across a wide range of building types.
Each coating features a leathergrain embossed surface and is available in a broad range of standard colours. Both are suitable for roof pitches down to 4 degrees and incorporate a high-performance reverse coating to support durability across the full system.
TPP Plastisol offers reliable performance with a guarantee of up to 25 years, while TPP Plastisol + is enhanced to deliver extended performance, with a guarantee of up to 30 years. In both cases, expected lifespan will vary depending on location, environment and colour group, with inland applications typically achieving longer service life than coastal installations.
To maintain performance and ensure the validity of the guarantee, a regular inspection and maintenance regime should be followed, including the removal of debris and contaminants from areas not naturally washed by rainfall.
