1. Where do you ship?
   • While shipping charges can vary dramatically, we ship to all US States and Canada.
2. How big of an opening do I need?
   • For any stair ordered with vertical balusters, you need an opening that is 2” larger than the diameter of the stair. Any stairs ordered with horizontal line rail needs an opening that is 4” larger than the diameter of the stair.
3. What is Floor to Floor height?
   • Floor to floor height is the measurement from the bottom floor’s finished surface to the finished surface of the upper floor.
4. Are the treads adjustable?
   • Some models are offered with an adjustable treads where your final riser height can be determined on site, during installation.
5. Can I order a galvanized stair finished in a particular color?
   • We do not offer a color finish on our galvanized stairs because this is largely dependent on surface preparation and the environment in which they are installed. Our recommendation is to discuss preparation and methods with a local painter or paint store to get some helpful tips.
6. Is the travel direction reversible or does that have to be determined before I order?
   • Most of our standard models’ rotation (travel direction) are reversible and can be determined on site, during installation.
7. How do I know if the stair I want meets code?
   • Our team of design consultants are well-versed in the most current code requirements and can answer any questions you have. We always recommend contacting a local building code inspector to make sure you know what code is enforced in your particular area.
8. Do you provide any documentation for building code inspectors or architects?
   • For an additional fee, we can provide documentation in many different formats and requirements; from shop drawings to engineering stamps and calculations.
9. Is there anything I can do to fill up some of the gap between treads?
   • We offer riser bars and limiters for our econo and econo + models. For our classic series, we also offer many different code compliant tread styles for a similar effect.
