International Building Code Guidelines overview for commercial buildings and common stairs in buildings. It is much more complex, but these are the general rules.

Stairways have to be at least 44″ if occupant load is over 50 and 36″ width if under 50 occupants you can go to. Stairs must have at least 80″ of head height measured off the tread nosings and it needs to be maintained for one additional riser depth at the bottom of the stairs. The riser height must be between 4″ and 7″ and the treads must be at least 11″ deep.

Stairs with winders need to be at least 11″ deep and when 12″ in from the narrow edge and the minimum depth must be 10″. ErectaStep commercial stairs with winders will be custom orders.

Stair landings a required for 12′ vertical stairs inclines and must be at least as deep as the stairs are wide (up to 4′-0″). Where a door opens into the landing it can’t project more than 7″ into the required depth of the landing.

Handrails in IBC buildings need to return to a wall, a guard or the walking surface or continue to another handrail. The IBC requires that your handrail extend 12″ past the top riser and one tread depth past the bottom riser. It important to note that the ADA will require you to go one tread depth plus 12″ past the bottom riser so it generally overrides the IBC.

Stair handrails need to be on both sides of the stair and can’t project more than 4.5″ into the stair width on each side. On a very wide stair you need to space intermediate handrails no more than 60″ apart. They are required to be mounted between 34″ and 38″ above the tread nosings and landings and mounted a minimum of 1.5″ off the wall. ErectaStep uses Round aluminum handrails and it’s required they need to 1.25″ to 2″ in diameter. While not applicable to ErectaStep’s commercial handrails, square handrails is required to have a perimeter between 4″ – 6.25″ with a maximum cross section of 2.25″.

Will definitely buy again in the future.

John Bast was very quick to reply and very helpful. In my experience, some shop-built or pre-fabricated systems are of low quality. The design and manufacturing quality was better than expected. All positive comments, nothing negative. Will definitely buy again in the future.

It has all of the safety features you could ask for plus more!

ErectaStep does an awesome job of meeting PO requirements and shipping time. We are appreciative of the customer service. Simple installation is key. With employees day-to-day tasks, we didn’t want something that [would take] a while to install.
