Building Code Policy
As Lapeyre Stair expands its product line to provide you with more options to meet
your access requirements, we are striving to incorporate into our engineering design
the flexibility and interchangeability of components needed to selectively meet
the requirements of the various laws, standards, and building codes in operation
in all parts of the world.
We also strive to provide you with real value in your access device purchase. To
achieve the goal of providing you with real value, we will endeavor to provide you
with design alternatives that will meet your local requirements. Because of the
infinite complexity of knowledge needed to understand the diverse regulations of
all local political and geographic regions we have decided to offer products that
in general can be selectively configured to meet the requirements of several of
the primary United States, and International laws, standards, and building codes
as described in their current or most recently issued editions.
And although we can not guarantee that a particular stair configuration will be
accepted by your local authorities; we stand at the ready to quickly provide you
with detailed drawings of our access devices, prior to your purchase, that you may
submit for compliance approval.
Your local architect, local building code officials, and your local codes are your
best source of compliance specifications/recommendations at your location.
All capacity ratings for Lapeyre Stair conventional tread stairs are stated in terms
of the live load capacity of the stair system with a given safety factor. Local
wind, snow, and seismic rating requirements are not included in this capacity rating.
Local requirements for these loadings, where applicable, must be considered by your
local architectural or engineering professional.

- Alternating Tread Devices
- Fixed Industrial Stairs

Some General Access/Egress Device Types
Non-Conventional Access Device Types
Vertical Ladders
(generally applied at 75º to 90º)
-Characterized by very narrow tread depths (or rungs) and very large rise. |
Ships Ladders
(generally applied at 50º to 70º)
-Also known as: inclined ladders
-Characterized by shallow tread depths and large rise. |
Alternating Tread Devices
(generally applied at 50º to 70º)
-Special design device that allows for deeper safer tread depths and large rise.
|
Conventional Access Device Types
Fire Escape Stairs
(generally applied at 30º to 50º)
-Unprotected stairs and ladder systems exterior to a buildings outer walls.
-Only used in emergency situations. Wide latitude in rise run dimensions.
|
Fixed Industrial Stairs
(generally applied at 30º to 50º)
-Also known as: limited access stairs, equipment access stairs, utility stairs,
secondary access stairs, auxiliary stairs, or special occupancy stairs.
-These stairs generally allow for more latitude from the ideal ergonomic rise run
configuration. They are allowed under some egress codes in special circumstances.
They may be applied for convenience in areas where egress requirements are met by
other devices.
|
Industrial Egress Stairs
(generally applied at 25º to 32.5º)
-These stairs are egress stairs where the occupancy is limited to trained personnel.
-They are similar to egress stairs but are allowed special design exemptions because
they are utilized in industrial environments and children and the general public
will not have access to them.
|
Egress Stairs
(generally applied at 30º to 32.5º)
-Protected or unprotected stairs internal or external to a building for primary
emergency egress as defined by a Building or Fire Safety Egress Code
|
Accessible Stairs
(generally applied at 30º to 32.5º)
-Designed to be more accessible for the handicapped or disabled individual.
|
Accessible Egress Stairs
(generally applied at 30º to 32.5º)
-Stairs that combine all the features of Accessible and Egress Stairs.
|
Ramps
(generally applied at 0º to 20º preferred at 7º to 15º)
