Nola's pine is of high quality and comes from sustainable forestry. Pine is an environmentally friendly, domestically produced material. Damaged or untreated pine is quite easily attacked by decomposition processes; therefore, it is particularly important to repair damaged surfaces.
The quality of red oak is very high, usually without visible knots. Due to its high content of tannic acid, a very high outdoor durability is a given. Red oak that is not maintained gets black spots after a while. The spots gradually fade and after a couple of seasons turn gray, similar to teak. Smaller cracks also usually appear as oak is a very "lively" type of wood. These cracks have a marginal effect on the material's strength and resilience.
Oak is a heavy, hard and medium tough wood. Moderately dimensionally stable in case of moisture changes. Oak wood blackens if it is exposed to moisture or wetness for a long time. However, it does not affect the other properties of the wood. Thanks to its hardness and toughness, the oak wood is suitable for furniture and other use in exposed environments.
Wood oil provides good protection against the stresses of the outdoor climate and at the same time highlights the wood's natural appearance and properties.
Varnishing of wood is done with a water-based varnish. A water-based paint that is kinder to the environment. Under normal use, the paint has a good wear resistance and long durability.
After traditional impregnation according to NTR AB, the wood is boiled in a hot linseed oil with or without color pigments under vacuum. The oil is penetrated into the surface on all six sides, which reduces moisture absorption in the wood and gives a dimensionally stable product over time. The result is a dried product with good resistance to rot that also has long maintenance intervals.
Nola uses high-quality steel of good strength in our products. Steel rusts if left untreated and must therefore be surface treated. For this we use two main methods for surface treatment of steel parts; electrogalvanizing and powder coating as well as hot-dip galvanizing.
Electrogalvanizing (also known as zinc plating) provides corrosion protection through the sacrifice of zinc ions. It is created via a zinc coating on the steel using an electric current.
Powder coating is a coating that is applied as a free-flowing, dry powder. Unlike conventional liquid paint, powder coating is usually applied electrostatically and then cured under heat or with ultraviolet light. The result is an even, hard-wearing coloured surface with the desired gloss level.
