Boeing contacted SlipNOT® Metal Safety Flooring for a product that would be durable, lightweight and corrosion resistant while maintaining slip resistance. SlipNOT® provided Boeing with stainless steel on aluminum stair treads for their application. Stainless steel on aluminum was the ideal option for the application because the aluminum metal substrate is extremely lightweight which makes the stairs very mobile when working on multiple planes. The stainless steel coating is ideal because it is extremely durable and corrosion resistant. When the slip resistant steps come into contact with oils, lubricants and coolants they will not corrode and will remain slip resistant. Furthermore, to create the safest work environment possible, Boeing painted the stair treads yellow. By painting the stair treads yellow, Boeing took preventative measures to ensure workers working on the stair treads would be noticed and that pilots moving planes would be aware of the location of the stair treads to prevent accidents.
