PRODUCTIONS PROCESS$-$lTables are made of three parts $$ round glass, aluminium disc hardware, and timber legs.

While the glass is cut into a round shape, the discs are cut from aluminium coils. The aluminium hardware is then glued into the glass. At the same time, legs are made from wood lumbers. The wood is cut into standard pieces and then shaped using a lathe. After sanding and coating, the legs are packaged together with the glass $($and its aluminium hardware attached to it$).$ Finally, the flat pack is briefly

inspected to ensure all the components have been included.

$$ Tempered glass is supplied by CrystalCraft Glassworks every fortnight.

$$ Aluminium coils are supplied by AluCoil Producers every fortnight.

$$ Wood lumbers are supplied by ForestHarvest Wood on a weekly basis.
