Exterior stairs need to be able to withstand more extreme weather conditions. Our exterior stair package includes exterior paint which is basically 3 times the paint and primer that our interior spiral staircases get.

Exterior spiral staircases also need to be more resistant to moisture and the suns UV rays. The treads we offer are similar to what you would use on an exterior deck: wood (redwood or cedar), pressure treated wood or composite (such as Trex Composite for decks). Composite treads are a little more expensive than the wood treads but we can match your deck color. The composite treads are the most durable.

All metal treads come in a couple of options. Expanded metal treads have a diamond shape hole that lets the rain and snow fall through. Snow can build up but when you walk on it you will push the snow through the holes. Tread plate, or checker plate is also used for its durability.

To save money the customer can buy their own composite and install their composite on our frame. We will send a pattern and directions with a drawing showing how to cut and install the composite.

A steel spiral staircase is an ideal choice for home or office and can be used indoors or outdoors. Indoor spiral staircases are great for open floor plans. They invite natural light in, and add value to the space. Outdoor steel spiral staircases are the perfect option to connect your deck to yard or patio spaces.

Our spiral stairs are already assembled at our factory to your personal specifications. Having the staircase already welded together means that you simply bolt the top landing up to where it goes, set the staircase up to the landing and vice grip the landing to the landing bracket. You will need to drill 4 holes into the landing then use the bolts supplied to bolt them together. Then bolt the base plate and the tabs on the bottom balusters down to the floor. If your stair is all steel you are done. If you have oak treads and or handrail, it comes un-finished. You will need to stain and finish the wood to your satisfaction and use the screws supplied to attach the wood parts to the stair.

Goddard Steel Spiral Staircases are usually built in 1 piece. Our customers often ask “how do we get them into the house”? A 5’ diameter steel spiral staircase will cork screw through a 36” door that measures at least 34 ½” from jam to jam. You will need to have a straight shot to where the staircase will go. The staircase will not fit down a hall way or through a small entry way getting them into the house. If you have a hall way that is not large enough for the staircase to go through we can build your staircase in 2 sections and bolt them back together using only 7 bolts and screws.

Your custom made spiral staircase usually arrives at your home by our personal truck. You the customer will need help to unload the staircase and take it to the yard (exterior) or into the house (interior). Our driver is usually capable of helping you with this. Steel staircases are welded into a single unit but can be made in 2 pieces to get it into your home.
