Safety products may easily be retrofitted over existing unsafe material such as stair treads or ladder rungs. Products can be welded, bolted or adhered over any type of flooring such as wood, concrete, or metal. Products can usually be custom fabricated to retrofit unsafe conditions and meet regulatory compliances and codes. Incorporating safety products into the design stage meets regulatory requirements at reduced costs. In some cases, retrofitting unsafe conditions can require complete replacement of products at significant expense.
