When it comes to height, there are two main aspects:
- Overall height measured on the outside
- Interior clearance
The overall height may be regulated by zoning laws, but the clearance height will usually have more of an impact on your design decisions. At the low end, 10 ft. clearance is plenty for many applications. Heights of up to 30 ft. can accommodate your extensive warehouse shelving systems, your warehouse heavy construction vehicles and tractor-trailers.
Roof -Shape & Pitch
The building dimensions of your roof are extremely important to consider when constructing a metal warehouse building. Make sure you look at both the shape and the pitch of the roof as rigid frame metal buildings can come with several types of roofing options and you want to make sure you get the roof that will best suit your warehouse needs.
- "Single slope" construction starts with one side wall higher than the other and the roof simply slants from the high wall to the lower.
- "Peaked" or "gable" roofs have a more traditional peak, with the roof running down to both sides.
When it comes to the pitch of your roof, it’s usually expressed as a ratio. For example: 1:12 is the flattest type of roof, rising 1" for every 12" of width. 4:12 is usually the steepest pitch available for steel buildings. Increased pitch gives you more interior clearance which is great for warehouse buildings; it also helps improve the building's ability to shed rain and snow and can result in a better looking building (more on roofing here)
Once the design of your building has been established, there are a few more things to consider before the actual building begins and they include:
Engineering-Once the basic design is complete and you've paid a deposit, an engineer needs to create the specifications and blueprints for the building. The blueprints will specify what materials should be used and what loads the building will need to be able to withstand to meet local building codes.
- Fabrication and Delivery-After the blueprints are signed off on, the real production begins. The beams, posts, girders, side and roof panels, and even the fasteners to hold the building together are all produced at a factory, then shipped to your construction site. The parts are pre-cut to the exact dimensions you need, pre-drilled, and ready to be bolted together. This step can take 3 to 6 weeks so factor in this time when thinking about the overall construction process.
- Sitework-While the components are being manufactured, the building site can be readied. Steel buildings require foundations, which are usually poured concrete.
It’s Finally Time To Build:
- Construction-Once the components arrive and the foundation is ready, the actual construction can take place. This can be done on your own with the manual, or you can hire an erector to help you put up your building.
- Finishing- Adding insulation, interior walls, exterior finishes, doors and windows, steps, plumbing, and all the pieces that turn a metal box into a building you can appreciate. Your warehouse building might not need that many extra additions depending on its use.
- Walkthrough-Like any construction project, your steel warehouse building needs to be approved by a building inspector once it is completed.
