ABSTRACT
This aim of this project was to construct a steel cupboard inorder to help us acquire the knowledge of fabrication of a modern cupboard and the essence of it. Also to enable us (the student of chemical Engineering) to know how to construct as future engineer.
The construction of steel cupboard was done using a square pipe of 1.8mm thickness and the mild steel havling a thickness of 1.5mm. It was mark, out, cut, welded, filled and painted. The cupboard has length and height of 1150mm and 1160mm and dept 400mm. A grade of 12 electrode was used for the welding process.
The material used was locally sourced and selected to suit the desired purpose. Mild steel was used due to it’s cost and it’s corrosion free nature. No problem was encountered as regards the construction work. As a result of the quality of the material and it’s properties, a guarantee or ten years is given to the constructed work. Advantage of steel. Cupboard as in preservling and securling of Laboratory chemicals and equipment, keeping of document in offices out ways it’s disadvantage, the cost of production of the steel cupboard was fifteen thousand naira.

CHAPTER ONE
INTRODUCTION
Since human wants are practically unlimited and the resources for satisfaction are unlimited in supply, for this reasons, the creation of storage structure was initiated to preserve the available resources. Thus the storage structure is the cupboard.
A cupboard is a set of shelves with doors in front either built into the wall of a room or as a separate piece of furniture. There are so many kinds of cupboard such as office cupboard, kitchen cupboard, linen cupboard, laboratory cupboard and so on. The general use of cupboard is for spring materials in the laboratory, homes, offices, kitchen. These are used to store items like food, books, cloths, files, dishes, audio and video cassettes etc. Cupboard can be constructed with materials like wood, steel and some other kinds of metals.
However, steel as a material of construction of this project has more advantage over wood. Steel is not attacked by termites or insects and lasts longer than wood. The steel cupboard is usually rectangular, square in shape and cannot be broken like wood cupboard. This makes the materials kept inside very preserved and safe. Though metals commode as a result of presence pf air, moisture and chemical, the corrosion can be prevented by painting and coating it.
In construction of a stall cupboard many factors are considered such as availability of the material of construction, its durability and quality. Wide ranging research work is carried out to obtain the best possible design with the desired type of structural material for the cupboard being put to use. This is because there are varieties of materials that could be used for construction. Such varieties of materials are cast iron, wrought iron, low carbon steel, mild steel aluminum and aluminum alloy. The classes of construction materials apart from wood has a very high range of advantages as they are stronger and more machinable. They also have properties like thermal and electrical conductivity, high tensile strength, reflectibility and ductility.
Moreover, mild steel is usually most suitable for fabrication processes that involve cutting, bending, folding and other operations. This is because it is easily machined and can be handled without risk of wear and tear. The cost was also considered so much because it involves the quality of materials both in design and construction. It is possible to produce a quality steel cupboard with reduced cost.
Finally, the steel cupboard has wide ranging application and importance. It is necessary in the preservation and storage of documents, equipment, chemical species and laboratory equipment.
