Manufacturer

Aurubis is a world-leading copper producer. Their “Nordic Copper” range includes sheets, panels, shingles, and coils, with factory-applied finishes that either age naturally or are pre-coloured.

Material & Finish

– Copper naturally changes colour over time. Bright new copper gradually turns brown, then chocolate, and eventually develops a green or blue patina if left to weather.

– You can also choose pre-coloured or alloyed options like Nordic Brass, Nordic Bronze, and Nordic Royal, which give instant colour without waiting for natural ageing.

– Copper is durable, corrosion-resistant, and looks beautiful for decades. It also allows a continuous finish across roofs, façades, and accessories.

– Timeless, evolving appearance that adds character.

– Perfect for premium roofs and façades.

– Durable and weather resistant.

– Consistent look between roof and walls.

Colour & Appearance Options
Mill finish bright copper that ages naturally.
Pre-patinated colours: green/blue, brown.
Alloyed finishes:
– Nordic Brass – warm golden tone
– Nordic Bronze – rich brown
– Nordic Royal – premium golden alloy

Manufacturer

VMZINC is a leading manufacturer of rolled zinc products primarily used for building envelopes, including roofing, cladding, facade systems, and rainwater systems. They have a long history, manufacturing these products since 1837.

Material & Finish

Natural

– Natural VMZINC: Shiny metallic appearance when new; naturally develops a matt, light-grey patina over time (can take several years).

Pre-Weathered

– QUARTZ-ZINC: A uniform, matt grey finish achieved by a surface treatment (phosphatization) that mimics the natural patina of aged zinc from day one. It is VMZINC’s signature finish.
– ANTHRA-ZINC: A dark matte black pre-weathered finish with a visible grain, often used to complement slate or dark materials. It gradually lightens to a dark charcoal grey.
– AZENGAR: The first engraved zinc finish, resulting in a matt, heterogeneous, and light appearance.

Coloured

– PIGMENTO®: Based on QUARTZ-ZINC, these finishes incorporate natural mineral pigments to offer various colors while still preserving the natural texture and grain of the pre-weathered zinc underneath.

Lacquered

– Bilaquered VMZINC: Natural rolled zinc covered on both sides with a layer of polyester lacquer and primer for a broader range of colors.

Exceptional Durability: Provides an estimated service life of over 100 years for roofing due to the self-protecting patina (zinc carbonate layer) that forms naturally.

Low Maintenance: The self-healing patina makes the material virtually maintenance-free throughout its long life.

Design Flexibility: It’s a highly malleable material, allowing it to be easily formed into complex shapes and curved architectural designs (e.g., standing seam systems).

Sustainability: It requires less energy to produce than many other common metals and is highly recyclable (over 98% recovery rate).

Aesthetic Range: Offers a wide variety of consistent pre-weathered and colored finishes (like QUARTZ-ZINC and PIGMENTO®) for diverse architectural looks.

Colour & Appearance Options

VMZINC offers a vast pallet through its surface finishes, allowing designers to achieve different aesthetics:

Metallic Tones:

Natural Zinc: Starts shiny, transitions to light-grey matte.

QUARTZ-ZINC: Signature uniform, stable matt grey.

ANTHRA-ZINC: Dark charcoal to black, slate-like appearance.

AZENGAR: Light, matt, and textured (engraved).

PIGMENTO® Colors: These colored finishes, which retain the natural texture of the zinc, are available in a range of hues, including:
– Blue
– Green
– Brown
– Red
– Grey
– Charcoal Blue
– Storm Grey

Manufacturer

GreenCoat is a brand of innovative, sustainable color-coated steel products primarily used for roofing, facades, and rainwater systems.

The GreenCoat brand is manufactured by SSAB, a Nordic and US-based steel company known for high-strength steel products and a strong focus on sustainability.

Material & Finish

GreenCoat is a multi-layer coated steel product that prioritizes performance and environmental benefits:

Core Material: Nordic quality steel substrate, which is known for its purity and tight tolerances.

Protection Layers: The steel core is coated on both sides with a protective zinc layer for corrosion resistance. A pre-treatment layer and a primer are then applied to enhance corrosion protection and adhesion.

Top Coat (The Key Feature): The top coat is the defining feature. Most GreenCoat products feature a Bio-based Technology (BT) coating where a substantial portion of the traditional fossil-based oil is replaced with Swedish rapeseed oil.

– This patented solution significantly reduces the environmental footprint compared to conventional steel coatings.

– The total thickness of the colour coating typically varies depending on the product.

Sustainability: Features a unique, patented Bio-based Technology (BT) coating where a significant portion of the fossil oil is replaced with Swedish rapeseed oil, reducing environmental impact.

Extreme Durability: Proven resistance against harsh weather with high classifications for UV stability and corrosion, supported by up to a 50-year technical guarantee.

Excellent Formability: The material is highly flexible and workable, allowing for installation even in cold temperatures without cracking the coating.

High-Quality Core: Uses Nordic quality steel, which is known for its strength and purity.

Colour & Appearance Options

GreenCoat offers a vast and flexible color palette:

Wide Color Range: Available in an extensive range of colors, often exceeding 400 options, which are inspired by Nordic nature and modern architectural trends.

Customisation: A wide range of customised colors and finishes are available, and new colors can be matched to meet specific project needs.

Finishes/Gloss Levels: Products are offered in various appearances depending on the coating used:

– Regular (Standard Gloss)

– Matt

– Satin

– Metallic

– Shine Effect (e.g GreenCoat Hiarc)

– Mica (a glittery surface, e.g GreenCoat Mica BT)

Manufacturer

UGINOX is the brand under which APERAM, a major global producer, offers its range of high-performance stainless steel products for building applications, primarily roofing, cladding, and facades.

Material & Finish

The core of the UGINOX product line is Stainless Steel, an iron-based alloy that achieves its unique properties from its composition and surface treatments.

Core Material (Stainless Steel Alloy): Steel containing a minimum of 10.5% Chromium (Cr), along with other elements like Nickel (Ni) and Molybdenum (Mo) depending on the grade.

– The key is the Chromium, which forms a continuous, self-healing, Chromium Oxide “Passive Layer” on the surface, providing exceptional corrosion resistance.

– Common Grades: UGINOX products are available in various grades (e.g., Austenitic 304/316L and Ferritic K41/K44) to suit different environments (e.g., K44 and 316L are better for aggressive/coastal areas).

Key Finishes & Appearance:

UGINOX Patina

– Matt Grey Patina (terne-coated). It is stainless steel coated on both sides with pure tin (electroplated). It starts silvery and naturally weathers to a uniform, non-reflective grey finish, often used to mimic aged lead.

UGINOX Top

– Permanent Matt Finish. The matt appearance is achieved through a mechanical process (micro-texture engraving) during manufacturing.

UGINOX Bright

– Bright/Shiny Finish. A uniform and highly reflective surface finish.

Coloured/Textured

– Available in a range of colors (e.g., Gold, Blue, Black) via electrochemical processes, and various textures (e.g., Rolled-On, Linen).

Ultimate Durability: Self-healing passive layer ensures exceptional, 100+ year corrosion resistance.

Aesthetic Range: Available in a vast range of finishes (Patina, Bright, Matt, Coloured).

Installation Ease: Low thermal expansion allows for very long, seamless strips.
