ABSTRACT
The project done was a metal chemical rack. The rack was made of steel, which is soft to cutting, blending and several other operations applied to the metal during construction.
The main purpose of constructing this metal rack is to be used for storing chemicals in the laboratory for easy accessibility and safe keeping.
The to tal cost of the constructional project was estimated at the sum of Ten thousand (#10,000.00). This includes fabrication, welding and painting cost. The chemical rack is relatively cheap and it is light in weight.

INTRODUCTION
A rack is used / set for holding or storing chemicals in the laboratory. They are of different types, such as plate rack ,toast rack and wine rack .but the one we shall focus our attention on will be that of “chemical rack “,which is used for storing chemicals in the laboratory or used in a chemical process .In the industries or laboratories .materials are stored in the chemical rack refer to as chemical storage or facility for storage.
The material selection for the construction of any rack strongly depends on the properties and purposes that the rack will serve. Generally, considering all the metals and non-metals have their individual merits. But point to comparison between them will definitely show that in general, metals have a lot of advantages over non-metals.
For example, while many type of metal are suitable for high temperature operation, non-metals such as wood and glass are suitable for lower and limited range of temperatures. Metals posses a wider range of chemical stability than non-metals.
