All BOCA compliant stairs include the BOCA rail design, which is also used on all NFPA, SBCCI, and UBC Industrial stairs.

The OSHA compliant stair includes the OSHA railing design; however, the BOCA railing also meets OSHA requirements.

Contractors who intend to use their own wall rail system may choose to purchase the stair without one or both rails.

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.

Grip Tread

The grip tread, Lapeyre's most aggressive non­skid surface tread option, is available in standard widths.

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.

Bar Grating Tread

Lapeyre's bar grating treads are ideal for industrial applications. The serrated grating provides a skid­-resistant surface and each tread has a diamond plate nosing.
