Founded in 1954, we specialize in providing technical and decorative solutions for solar protection, metal ceilings and claddings that respect the environment and help to improve the energy efficiency, comfort and aesthetics of buildings.

2. INDUSTRIAL GRADHERMETIC, S.A.E., can be traced back to a carpenter’s workshop in Terrassa. It was
in 1949 when studying the blinds currently on the market, essentially limited to roll-up wooden slat ones,
that they came up with the revolutionary idea of a blind that would not only allow you to control the
direction of the slats, but also the angle and the amount of light.
To industrialize and commercialize this novel and revolutionary product, a new company was formed on the
12 th of February 1954: Gradhermetic.
Thanks to research and experience, the Gradhermetic blinds have evolved. Wood was no longer the first-
choice material, subsequently replaced by steel, finally making way for profiled aluminium, the material
used today.
We continued to grow, adding new services to our catalogue including the manufacture of metal ceilings,
claddings and shutters; and five years ago Llambí, the department in charge of unique projects.
Today, and having already celebrated our 60th anniversary, we have become one of the leading firms in
our sector. And just like when we started out, we continue to strive for innovation and excellence in
everything we do.

4. Aluminium coils with thicknesses between 0.25 and 1.5
mm.
Fundition
We manufacture aluminium alloy ingots for
subsequent rolling.
Tilting melting furnace with a capacity of 30 MT.
It is possible to produce infinite colour variations,
finishes, gloss levels and textures with the guarantee of
completely uniform properties in every batch.
Under the brand names Persistem and Prelac,
Gradhermetic markets its aluminium profiles.
Control over the process from start to finish, from
manufacture to onsite assembly and installation.
Coil coating
This process consists of applying organic coating
materials, resulting in a product with excellent
characteristics not only for its subsequent
transformation, but also in terms of durability and
resistance to corrosion and weather.
Onsite assembly / installlation
We provide an integrated service that starts with
the production process and continues through
to onsite installation, taking responsibility for the
correct functioning of the end product.
Profiling lines
We use cold profiling machines that transform the
pre-lacquered aluminium coils into profiles.
Rolling
We manufacture aluminium coils using hot- and
cold-rolling processes.
We are one of the few companies worldwide that can offer an
integrated production process. This allows us to control the
entire value chain of products, thus guaranteeing the very
highest quality standards.
Starting with stock aluminium and after a comprehensive
manufacturing process (melting furnaces, casting, hot-rolling,
cold-rolling, tension levelling, continuous painting lines, cutting
lines, profiling and assembly), we obtain the end product,
whose quality is controlled and verified by our approved
laboratories.
