Chromed steel offers a brilliant shine and lustre and also increases durability of a steel product. A thin layer of chrome (chromium) is applied to a steel surface to give it a brighter, shinier look, this also helps to promote corrosion resistance.
Chromed steel is a cheaper option than stainless steel, which includes chromium as a composite material within its alloy.
Stainless steel is steel alloy that includes a quantity of chromium (usually around 12%) to give it a stainless quality. On a chemical level, the size of chromium atoms and their oxides allow them to sit closely together, forming a surface that is more resistant to rust and stains.
Galvanised steel is steel that has been coated in zinc to improve its resistance to water and oxidisation (rusting). Galvanised steel is therefore more suited to outdoor use but, like all metal furniture, it is far more beneficial to keep it in a dry area. Scratches can occur which can affect the integrity of the zinc galvanisation, making the steel more susceptible to rusting.
Powder Coated Steel
Powder coating as opposed to traditional painting, forms a harder surface which makes the colour longer lasting and more durable. It is applied electrostatically as a dry powder and then cured under a heat to allow the powder to flow, forming a skin or coating. This technique means that a solvent is not required to keep the binder and filler parts in a liquid suspension, thus creating a harder finish.
Our aluminium bar stools have two finishes, brushed aluminium and cast aluminium which is then powder coated. Brushed aluminium is aluminium that has been brushed with an abrasive surface, usually fine grit sandpaper. This process gives the metal a pattern of very fine lines and has a mattifying effect, however, some of the aluminiums lustre and shine is retained.
Cast aluminium refers to the process by which aluminium is heated in order to melt it into liquid form. It is then poured into a mould and left to cool and set. The main advantage of casting aluminium, is that the process produces a product without joins or seams. This improves structural integrity.
