Roll of Steel
Using a form of transport to move your raw steel goods is probably the most cost effective way of getting your steel from A-B ie. before it has been created into its end product. Manufacturing steel items due to its weight and often bulk identity and lack of being able to reshape it (ie not like a cardboard box) is best done as close to a port of distribution or its place of retail as possible. These apparent links between steel manufacture and its distribution are most commonly noticed to work well in China and other successful areas of mass distribution and construction of Steel. Transporting an item after it has been manufactured to its ‘on the shelf’ condition is way more intense a procedure than the raw fabric it once started out as ie a roll.
For example if you where to get a fully constructed push Bike from Hull to Portsmouth it would require packaging which could consist of bubble wrap, cardboard box, labels of identification etc… If a roll of steel was to be transported from Hull to Portsmouth in its raw condition of being a roll it would be placed onto the back of a low loader and sent via rail or road to meet its destination with the minimum of hassle and lower cost.
Roll over prefab
Now obviously some factors of cost do have to be incorporated into the production of a product, So if there is no way a Bike factory could be run and constructed in Portsmouth where as in Hull there is a Port for easy access a rail network for good distribution, its centred in the middle of the country for its own network of customers then its wise for them to be positioned in hull not in Scotland. So its not all about a roll of steel its also what makes sense demographically
