About Industrial Stairs
Materials and finishes
Industrial metal staircases are typically made of powder-coated or galvanized steel. Choosing the right material finish depends primarily on environmental and aesthetic factors.
Because galvanized steel is more durable, longer lasting and maintenance-free, it’s the best choice for stairs in outdoor environments. However, it can be more costly than powder-coated steel and is typically a matte gray color.
If the appearance of the metal stairway is a factor, then powder-coated steel is the way to go. Powder-coated steel staircases can be painted in an almost endless variety of colors and finished with different textures. While not as long-lasting as galvanized steel, powder coating still provides a durable, rust resistant finish which is easy to maintain.
Safety features
Handrails, guardrails and treads make inustria stairs safer than a standard stair ladder.. All Lapeyre Stair metal stairways come with handrails and guardrails designed to reduce the risk of slips and falls and comply with applicable OSHA and IBC standards.
Stair treads also play a key role in worker safety. Non slip stair treads are commonly used on outdoor stairs to increase traction and reduce the potential for accidents. Typically, the treads are covered with a light-weight, bolt-on tread cover which features a permanent, abrasive polyurethane coating.
Diamond plate treads feature a pattern of raised diamond on one side with the reverse side being smooth, which helps increase grip.. Bar grating treads feature an open grid assembly of metal bars to keep any liquid or other debris off the stairway. Grip treads feature a serrated surface which help reduce accidents by providing a safer walking and working surface.
Durability
Lapeyre Stair’s industrial metal stairs are constructed with heavy-gauge metal and built to last in any environment. Since steel is the strongest material that can be used for staircase construction, both powder coated and galvanized steel staircases are extremely durable and can withstand high traffic and heavy weight.
However, galvanized steel can be considered more durable than powder coated steel, as any dents or scratches won’t compromise its protective layer. Powder coating is porous and can be damaged under extreme force. Exposure to severe circumstances or heavy abrasion, can lead to chipping and cracking in the powder coating. This can leave the steel below exposed to the ill effects of the environment.
Customization options
Lapeyre Stairs provides custom designed industrial stair solutions for virtually any application. Handrails and guardrails are designed to meet OSHA and IBC standards.Treads are available in standard widths of 24″, 30″, 36″, and 48″, as well as custom width. Tread types include diamond plate, concrete pan, bar grate, grip tread and smooth plate. Finishes include galvanized steel or powder coated steel available in both standard and custom colors.

FAQs
What is the slope for industrial stairs?
For most standard industrial stairs, the stair slope varies between 30 degrees and 45 degrees. The slope of an industrial staircase can vary based on the use case and application for the stair.
What is the maximum riser height for industrial stairs?
The maximum riser height for industrial stairs varies depending on whether the staircase falls under OSHA or IBC standards. OSHA requires standard stairs to have a maximum riser height of 9.5 inches (24 cm). IBC requires that stair riser heights are a maximum of 7 inches (178 mm).
What are fixed industrial stairs?
OSHA defines fixed stairs as interior or exterior stairs serving machinery, tanks and equipment, platform stairs and stairs to or from floors or pits. Stairs intended for only fire exit purposes and stairs forming an integral part of machinery are not included in the definition of fixed stairs.
