Replacementsteps is the only patented and manufactured replacement step for exterior stairways of its kind in the marketplace today. Diamond plate metal, solid concrete, concrete poured in metal pans, or wood stairways are destined to become fatigued products, each in their own way. Their average lifespan can be as little as 7 years. They will never reach a lifespan that justifies the cost. Replacementsteps have an estimated lifespan of 30 years. The installation time for current stairway types is 10 hours, but is less than 4 hours for Replacementsteps. This new product has been engineered for superior strength, and its skid protection is the same used by the US Navy on aircraft carrier decks. It is superby durable, safe, long lasting, super cost effective, and maintenance free. It is the most feasible stairway renovation method available. For more details please visit our website.
