Armstrong has expanded its Natural Options luxury solid-vinyl flooring tile line with the addition of the new Metal and Chrome Metrics collections. Also, the company has expanded the line's Wood, Rustico Wood and Stone Collections with new designs chosen to reflect current style trends.

The new additions were developed to combine the look of natural textures with the performance and cost of vinyl flooring. All of the new designs can be used individually or in combination to create a variety of interiors.

The Metal Collection offers six designs, 14 colors and three tile sizes. The Chrome Metrics Collection features four designs and six colors in a single tile size, and the designs shift depending on the angle from which the floor is viewed, Armstrong says.
