Lapeyre steel bolted egress stair systems come with both guardrails and handrails designed within the parameters of the building codes and field conditions of each project. Guardrails and handrails can be used separately or in conjunction to accommodate a variety of configurations.

The Industrial IBC stair is the only industrial stair that requires the inside handrail in addition to a guardrail. For this reason, Model 03AA or Model 04AA are recommended when compliance with IBC for industrial access stairs is required.

FULLY BALUSTERED GUARDRAIL FILLER PANEL GUARDRAIL
Guardrails on both sides of the stair is the default option. Guardrails on both sides of the stair is the default option.
Guardrails may be eliminated when the stair is against a wall. Stairs without guardrails have a narrower stringer so that users, especially children, cannot slide down the edge of the stringer.

Commercial stairs have balusters that are spaced so that a 4" sphere cannot pass between.
Stairs ordered under the IBC Industrial Code have balusters spaced so that a 21" sphere cannot pass between two balusters.
Guardrails are available with a Filler Panel option. Guardrails are available with full balusters.
Balusters attach to stringers using provided bolts and spacers.
Filler panels can be painted with the same color finish as the stair or a complementary color selected by the client.

A varied assortment of stair tread options allow architects and engineers to create harmony between pre-engineered components and unique building designs.

Diamond Plate Tread

The diamond plate tread provides a solid tread surface with raised diamonds for a non­-skid effect. Custom width requests can be accommodated at the Lapeyre facility.

Concrete Pan Tread

Concrete pan treads are manufactured at the Lapeyre facility using the underside of the diamond tread plates. The diamond plate is wrapped around the front edge to create a diamond tread plate nosing. Available in standard widths and custom widths, pan treads arrive on­-site ready for installation and for site-­poured concrete.

Smooth Tread

The smooth tread's solid surface is designed to allow the installation of carpeting, non­-slip flooring surface, or other flooring material directly to the stair. This tread should not be used alone as it lacks a non­skid effect. Custom width requests can be accommodated at the Lapeyre facility.

Available Stair Angle and Height Charts

The minimum height, maximum height, and angle restriction ranges for Lapeyre's closed riser stairs vary based on the stair width and the type of tread. The two charts below provide guidelines based on height.

To read the table, the heights and angles are available for all heights (in feet) below and to the right of the colored line that represents each tread width. For example, a 36" wide tread is available up to 12' high at approximately the 25 degree angle and steeper, but not at a 21 degree angle, which has a height limitation of just over 10' high.

For specific heights/angles, please consult your customer service representative.
