Deck and Railing Testing

With an abundant selection of decking manufacturers, materials, colors, shapes, and sizes available to consumers, competitive decking and railing manufacturers can’t afford to lose projects due to a lack of technical data and product certification. Because each type of material used in decks and railings will have different performance characteristics and requirements, these manufacturers find their path to market acceptance shortest when they choose to work with third-party agencies with demonstrated expertise and trust from the market. Proactive manufacturers are planning their tests and certification during product development in collaboration with their third-party agency before their products go to market.

ICC NTA laboratories are accredited to the ISO 17025 standard, which ensures that you and your customers can rely on the validity of our results.
