Laser Cut Screens , Material Selection .
Weathering Steel ( Corten )
This is an architectural grade of steel used for making laser cut screens and sculptures because of the natural patina it develops with age . It has a high resistance to corrosion and its copper content helps in the development of it’s unique colouring . Bear in mind that this material will eventually drip rusty water in the rain and if it is in an area where it can be brushed against it may leave rust marks on clothing . Whilst Corten is corrosion resistant and will last a lot longer than mild steel , it will not last forever .
You have 2 grades to choose from 316 marine grade or 304 . If the laser cut screens are to be used outside , we suggest that you specify 316 . 304 stainless will eventually rust in the elements but is fine for interior use and is substantially cheaper .
Aluminium is a handy option for its’ corrosion resistance and light weight . It can be powder coated in a range of colours , anodised or left in a raw state . If left in the raw it will it will dull with age . The dull surface becomes a protective layer to help prevent further corrosion . You will need to avoid contact with dissimilar metals , this can cause electrolysis , especially in a marine atmosphere
Mild steel is the cheapest option for a laser cut metal screen . If you are planning to have your screens powder coated , this is a sound option for interior use . Powder coated mild steel for exterior use can be problematic and require more maintenance than anticipated . Be aware , powder coated screens should be unwrapped within 7 days of delivery . Failure to do so will cause sweating inside the plastic and shorten the life of the powder coating .
We don't recommend mild steel for rusting unless it is to be used inside with a sealer .
MDF and Plywood
These are good options for light weight interior screens . Some patterns are not suitable for timber screens .
This material is made from sawmill tailing and is bonded with resin . The screen featured on the home page has a woodgrain texture on one side and a canvas like texture on the B side . The reconstituted hardwood is also available with a smooth primed surface on one face and once again the canvas like texture on the B side . It is available in an exterior grade but painting or oiling is recommended .
