Angle Frame

We can build a tread that is simply a steel frame that you can add the tread onto. This is most often used when inlaying wood or synthetic decking.

NOTE: The preparation and construction of the “tread insert” for this tread is very time-consuming and must be very strong to properly support loads.

Deck Style

This tread is a complete system including the angle frame and the deck-style tread insert. Deck style refers to the design where the material (wood or synthetic decking material) is spaced and built mimicking the look of a standard outdoor patio deck.

We recommend a material durable enough for exterior use that also provides beauty, including pressure treated pine, Ipe’, or any of the currently marketed synthetic woods, such as TREX® or TimberTech®.

  • Exterior
  • Residential
  • Commercial

Brushed Stainless

Stainless steel is recommended where corrosion resistance is mandatory and minimal maintenance is desired. Environments where stainless would be very useful includes locations with proximity to saltwater, areas of constant exposure to precipitation such as rain and / or snow, and also where aesthetics dictate.

One finish available is “brushed #4”. The look is similar to that found on the exterior of new, hi-tech refrigerators and other high end kitchen decor. The brushed #4 finish is just one of the many stainless steel finishes available and is currently the most popular. Also available are a “high polish” and a “bead blast” finish.

NOTE: Requires additional Anti-slip material

Common Applications:

  • Interior
  • Exterior
  • Residential
  • Commercial

Available Metals:

  • Stainless Steel

Checkerplate
Also known as diamond plate or tread plate, this tread offers raise markings approximately every inch for traction.

Recommended for exterior use, we also see these treads being used a lot more indoors where an industrial, urban, or loft “look and feel” is desired.

Aluminum or Stainless Steel is recommended for exterior applications where corrosion resistance and minimal maintenance is desired. We do recommend a finish coat on aluminum such as powder coating or anodizing to protect the metal from oxidization.

NOTE: Enhanced Traction Tread

Common Applications:

  • Interior
  • Exterior
  • Residential
  • Commercial

Available Metals:
