Materials and production

It is possible to operate a profitable manufacturing firm in Scandinavia. It is possible to build a business based on longevity and sustainability.

Sustainability goals:

“Innovation and thinking big have been in the company's DNA since it was established in 1947. We now have seven decades behind us as an industrial company; all our production still takes place in Norway and Sweden, and our goals for the future are more ambitious than ever.”

Materials and production

Vestre assesses materials based on quality and environmental considerations. They must be able to withstand being outside for many decades, and have as low an impact on the environment as possible.

High-quality Nordic steel and aluminium

Vestre uses high-quality Nordic steel and aluminium that are sourced as locally as possible. The global steel industry is responsible for 7% of the world's greenhouse gas emissions. Greenhouse gas emissions from steel production in the Nordic countries are more than 20 % lower than average. This is made possible by state-of-the-art production plants and the high proportion of renewable energy used in production. Vestre furniture is solidly built and can withstand extensive wear and tear and use for many years. The steel we use is between 3 and 16 mm thick (1/8 and 5/8 of an inch). Steel plates and tubes are cut using advanced laser machines, which are extremely accurate and minimise resource wastage. Welding is carried out both manually and using automated robots. All components are processed and assembled with a view to achieving optimal strength and durability.

We use Hydro CIRCAL which consists of at least 75% recycled aluminium. This is the highest content of recycled material on the market, which means drastically reduced energy consumption, while the product is also of high quality and durable.

Sustainable timber

For our furniture we use high-quality FSC®-certified pine from Norway and Sweden (Pinus Sylvestris). Owing to the cold climate the trees grow slowly and can only be felled after 80–120 years. This means that Scandinavian pine is harder and more suitable for outdoor furniture than pine from warmer areas, which generally grows 3–5 times faster. Scandinavian pine has a hardness of 1,7 on the Brinell scale. Scandinavian forestry is amongst the most sustainable forestry in the world. The felling of virgin forest is prohibited by law and, consequently, timber production in Scandinavia has doubled over the last hundred years, with an annual increase in stock of 10%. Vestre's timber is impregnated with natural linseed oil which offers lasting protection against rot and virtually maintenance-free use. After some time outdoors, the surface will develop a grey patina.

Hot-dip galvanisation

Vestre standard, self-healing sink

If the surface is damaged, hot-dip products repair themselves by shrinking the zinc and forming a new coating in the damaged area. This is called cathodic protection.

International standard, powder-coated steel

When the powder-coated surface is damaged, the steel will rust and the rust will spread under the lacquer. Then bubbles that you often see on older cars will arise and eventually burst so that the rust becomes visible.

All steel components used by Vestre are hot-dip galvanised in a liquid zinc bath at 450 °C / 840 °F. The bath is exclusively heated using renewable energy, meaning zero emission of harmful greenhouse gases. This process provides a rust-free coating (80–120 μ) that enables Vestre's products to remain outdoors for several decades. Around 2–4 μ of the coating is lost in the first year as a consequence of use and climate impact and then the loss decreases to 1–2 μ per year. This guarantees a lifespan of at least 30–40 years outdoors. Steel that is powder-coated after hot-dip galvanising will have an even longer lifespan, as the powder coating protects the zinc. If the surface is damaged, hot-dip galvanised products repair themselves through the zinc contracting and forming a new coating in the damaged area. This is called cathodic protection. Hot-dip galvanising is a method that was patented by the French engineer Sorel in 1837, and which these days is carried out in accordance with the strict environmental requirements defined in ISO 1461. Zinc (Zn) is an important renewable construction material that occurs naturally in stone, water and human beings.

Powder-coating developed to cope with the North Sea

Before Vestre's products are powder coated, they are subject to extensive cleaning and processing in multiple phases. This process takes place in a series of immersion tanks and comprises degreasing, purified water and activators. The powder coating does not contain any solvents and is applied electrostatically through sophisticated nozzles. The powder is then melted in an automatic curing oven that gives the product its final appearance. The process was developed for the Norwegian offshore industry to ensure a very high finish that meets the strict requirements of Corrosion Class C5 (coastal areas with high salinity).

LT = Lifespan in years
LZn = Estimated lifespan of zinc plating exposed to the environment in question
LM = Estimated lifespan of lacquer coating exposed to the environment in question, if applied directly to steel

K = environmentally-dependent synergy factor, which can be set at:
1.5: for exposure in Environment Class C5
1.6 – 2.0: for exposure in Environment Class C3 – C4
2.1 – 2.3: for exposure in Environment Class C2

Example: a product surface treated with Vestre’s Duplex technology and exposed to Environment Class C5, will have a lifespan of more than 80 years*: * (=1.5*(40 years + 15 years)

Vestre’s unique surface treatment consists of wet zinc and powder coating. This process ensures a considerably longer lifespan than that obtained by separate systems.

The lifespan can be calculated by this formula:

LT = K(LZN + LM)

Corrosion Class
(EN ISO 12944)
C1 Heated buildings
C2 Outdoors in inland areas or in warehouses where condensation
may occur
C3 Outdoors in coastal climates with little salt content or indoors in production facilities with high humidity levels
C4 Outdoors in coastal climates with moderate salt content or in
indoor swimming pools
C5–I Outdoors in coastal climates with high salt content
(Vestre Standard)
Outdoors in coastal climates with high salt content, high
humidity levels, and aggressive atmospheric corrosion

Assembly and quality control

Only screws and attachments made from stainless or acid-resistant steel are used. The assembly process takes place both manually and by using robot technology. Prior to packaging and transport the products are subjected to a thorough quality check in order to ensure that they comply with our strict craft and finishing requirements.

Environmentally friendly transport

Vestre works in line with our decarbonization plan approved by the Science Based Targets initiative to ensure environmentally friendly transport. With the goal of zero-emission transport in the long run, we have implemented some emission-reducing value chain interventions in the short term:

• Switched to HVO diesel in all upstream transport with Jan Olaf Olsen Transport since September

• Switched to a biogas-fueled truck with DHL between The Plus and their distribution center in Oslo from 1st December

• Established a policy of minimum of 30% sustainable aviation fuel (SAF) on all air transport with DHL Express

And by the way, Elon - we ordered this in 2018, when will it arrive?
