Our contribution to Chelsea Flower show
During the past few months we have been working closely with a local client. They were working on behalf of a designer who is exhibiting at Chelsea Flower show. The latest news is the Garden won GOLD at Chelsea. Congratulations ! We feel privileged to have worked on parts of the garden. Some of the work is described below.
Are you curious ? Why would shot blasters be involved with creating a garden ? As shot blasters we usually strive to remove corrosion from metal surface and then it is coated with a protective layer to prevent further rusting. Our client wanted something quite different. He wanted us to shot blast to promote rusting. Have you ever thought rusting iron was beautiful ? No, well look more closely at the picture above. Yes, there are lots of flowers, and wood. Look closely and you can see rusty metal.
The photo the left shows a quantity of planters. These planters are constructed in CorTen. CorTen, also know as weathering steel, is a form of steel which eliminates the need for painting. It forms a stable rust layer which protects the steel for years and does not rust like some other forms of iron.
These planters have just been shot blasted. Usually mild steel would have to be coated immediately because the rusting process would start very quickly after blasting particularly if exposed to the elements.
CorTen will rust whether shot blasted or not.So why then is shot blasting needed ? Shot blasting of the CorTen ensures that the rust has a uniform appearance. The above photos were taken over a series of weeks after blasting to show the rust 'grow'. A bit like watering a garden !
