If you are the incharge in material handling at work, most of the times, it isn't easy. You have to do couple of inventories base on the schedule posted. In that way, you will be able to know what other material you need to re-stock. Each company has its own supplier on whatever material they need. However, if you are looking for a distributor of industrial components and supply, you might check out Reid Supply Company about their stock. They have wide selections of each material they are selling so your shopping is easier and you don't have to hop from one store to another. You can save time and use it to do more stuff at work.
