Manufacturing vs. Prefab – What’s the Difference?

Here in manufacturing at ColonialWebb, we are referred to by many different names within the company. For example, you might hear someone call us “the shop,” “fab shop,” “prefabrication shop,” or “the controlled environment.” Most of these are acceptable names when referring to us on the fly, however, some can carry half definitions of what we do. At the core of it, there are two functions that the shop performs: Prefabrication and Manufacturing Products. Let me explain the difference between the two.

[simple_tooltip content=’Prefabrication is a method of construction that consists of assembling components offsite in a controlled environment (like a manufacturing floor). The partial assembly will then be transported to a location where it will connect to other components and installed permanently.’]Prefabrication[/simple_tooltip] is the partial making of something before the finalization of the actual product.

Think about a racked system on wheels that contains multiple runs of piping racks that are numbered from 1 to 10. This rack contains a line in the drawing that must be eventually connected with other components onsite. That is prefabrication and it serves as a time saver for installations.

[simple_tooltip content=’Manufactured Products are items that are built from raw material as complete units or systems.’]Manufactured Products[/simple_tooltip] are built as complete units or systems. For example, mechanical skids are complete by design and need to be placed in position to be hooked up.

Let’s take sheetmetal duct (a manufactured product) for instance — did you know that none of the sheetmetal duct you see on a jobsite is made on a jobsite? That’s right… Typically, all of it started as raw material in our shop that comes to us in large rolls of metal called coils (first photo below). After some cutting, forming, fitting up, and sometimes welding, complete products are made (bottom two photos)

   

 

Although we may be called many different names, there is one thing that we have in common here in manufacturing — we are a team that works together daily to support our construction, special projects, and service teams across our seven locations. If you have an idea or drawing on paper, we bring it to life.

Dispose of Aerosol Cans the Proper Way

Last Earth Day, one of our manufacturing teammates suggested a safer way of disposing of paint cans. When it comes to the high demands of running a manufacturing floor, our teammates can go through a few cases in a day or two based on the components or products that we are producing at the time.

Justifiably, aerosol cans are prohibited from being thrown directly in the trash in some municipalities. If you think about the landfills where trash is collected, you can imagine the impact these containers can have on nearby surroundings. Aerosol cans that contain paint, cleaning chemicals, or other solvents can be very hazardous to animals, trash collectors, and the environment if not disposed of properly. To add insult to injury, quite literally, these cans are pressurized which means that they are explosive under specific conditions.

Even when we think that cans are completely empty, there is still quite a bit of chemical or hazardous waste left inside. Here at ColonialWebb’s manufacturing floor, we use an Aerosol Can Waste Disposal System which allows us to safely puncture the can and drain the remaining contents out before disposal. This is not only a safer alternative to eliminating waste, it also enables us to condense the can and physical space in our trash dumpsters from the ability to crush the containers.

Yes, there are specialized companies that can come in and dispose of our waste for us, however, doing it this way ensures that the difference is made by us directly, one can at a time.
