Technical Information and Materials
All of our aluminium notes are anodised. Anodising is the process by which the natural film on aluminium is greatly increased in thickness. Anodising enhances the natural metallic lustre of aluminium while, if desired, applying durable and vibrant colour through an electrochemical process. The finish is ideally suited to exterior use, is very resistant to UV exposure and will not crack, peel or blister so often associated with painted finishes.
Glass Reinforced Plastic (GRP)
GRP is more commonly known as Fibre-glass. It is a modern composition of materials reinforced by fine fibres made of glass. It is very strong – seven times the flexural strength of steel – yet very lightweight. As GRP is extremely strong and robust it is ideal for harsh weather conditions. Recyclable and virtually maintenance free it is such a versatile and well-proven construction material that it can be used for many applications. Percussion Play uses this amazingly versatile material to make the notes for a number of our chimes and instruments. We have carefully selected the colour to resemble one of our favourite timbers – Purple Heart. Purple heart is a hard wood from tropical South America and is a dull grey brown when freshly cut but soon oxidizes to a violet purple. Our GRP ‘Purple Heart’ notes sound and look almost as good as the real thing but haven’t travelled nearly as far!
Also called Brazilian walnut, ipe (pronounced ee-pay) wood is typically found in South America and some parts of Central America. It is one of the densest hardwoods available, with exceptional resistance to decay, rot, and insect attack. Three times harder than cedar, it has the same fire rating as concrete and steel, meaning it resists flames much longer than softer woods, and is so dense that it doesn’t float in water. Ipe is extremely dense and durable.
Where necessary, screws used in manufacturing our instruments are security screws that are stainless steel vandal resistant and virtually impossible to remove, without the special, matching screwdriver or screwdriver bit.
Stainless Steel Frames
All of our frames are made from Grade 316 stainless Steel for maximum durability. All of our stands are designed with extended legs for below ground installation. Alternatively at an extra cost a surface mounted version is available with bolt down base plates. Wall mounting your instrument can be a real space-saver and will add a little life to a dull wall. Further information on request.
Where specified, instruments come complete with heavy-duty robust vandal resistant beaters. All our beaters are one-part cast polyurethane with integrally moulded cables, so there are no nuts or screws that can be loosened. We’re pretty confident in saying our beaters are the strongest on the market.
