Standing Seam Roofing Made from Swedish SSAB GreenCoat PLX Steel

Standing seam roofing made from premium Swedish SSAB GreenCoat PLX steel is a professional solution for both modern and traditional roofs where high standards are required in terms of durability, workability, resistance, and final appearance.

GreenCoat PLX steel was developed by SSAB in cooperation with sheet-metal roofing professionals specifically for standing seam roofs and demanding sheet-metal applications. The material offers excellent formability and minimal springback, making it possible to create precise and tight standing seam joints.

Main Advantages of SSAB GreenCoat PLX

One of the key advantages of Swedish SSAB steel is its excellent formability. The material is specially designed for both manual and machine seaming, as well as for producing details, junctions, flashings, and other custom sheet-metal components.

Thanks to its mechanical properties, the steel performs exceptionally well during fabrication and installation, making it suitable even for technically and architecturally demanding roofs.

The main advantages include:

• premium Swedish SSAB steel,

• material specially developed for standing seam roofing,

• excellent formability,

• minimal springback,

• ability to create very precise and tight standing seam joints,

• high corrosion resistance,

• excellent resistance to weather conditions,

• high-quality and durable surface finish,

• excellent colour retention,

• good resistance to mechanical damage,

• possibility of producing long roofing strips,

• suitable for complex sheet-metal details,

• long service life,

• premium appearance of the finished roof.

Specific warranty periods and conditions are always subject to SSAB's current warranty terms and the selected surface finish.

An Ideal Material for Standing Seam Roofing

SSAB GreenCoat PLX is designed primarily for professional sheet-metal roofing applications. The combination of strength, high formability, and premium surface protection makes the material suitable not only for straightforward residential roofs but also for complex roof structures, dormers, parapets, extensions, façades, and other architectural applications.

The material is also highly suitable for custom-made sheet-metal components and details requiring repeated bending and forming.

Long Standing Seam Panels

We manufacture standing seam panels in lengths tailored to the specific project and customer requirements.

For roofs requiring exceptionally long panels, on-site profiling of long standing seam strips using professional roll-forming equipment can be arranged following prior technical consultation.

This solution helps minimise the number of transverse joints and creates a clean, technically sound roof surface.

Surface Protection and Long Service Life

GreenCoat PLX is designed for long-term use in demanding outdoor environments.

The combination of high-quality Swedish steel, a substantial zinc protective layer, and a premium surface coating provides excellent protection against corrosion, UV radiation, weather exposure, and mechanical stress.

With corrosion resistance of up to RC5+, selected versions can also be used in environments with high corrosive exposure, always subject to the specific project requirements and the manufacturer's technical guidelines.

A Professional Solution for Demanding Roofs

We recommend standing seam roofing made from Swedish SSAB steel particularly to customers looking for a premium alternative to standard steel roofing and for whom the lowest initial purchase price is not the only consideration.

It is a professional roofing material for projects where long service life, high-quality detailing, excellent durability, precise seam forming, and a premium appearance are important.

Thanks to its exceptional formability and properties specifically optimised for professional sheet-metal work, SSAB GreenCoat PLX is particularly well suited to high-quality standing seam roofing applications.

Technical parameters such as RC5+ corrosion resistance, a zinc coating of 350 g/m², typical elongation of 41%, and forming at temperatures down to −15 °C apply specifically to GreenCoat PLX Pro BT and are stated by SSAB in the product's technical specification.

For the warranty, it is advisable to retain the wording “up to 50 years” rather than simply “50 years”, as the warranty period and scope depend on the specific GreenCoat PLX variant, environmental conditions, application, and SSAB's current warranty terms.
