VIS base hardware is available in two standard material options: aluminum and steel.

Note: Colors shown are for representation only.

Actual color chips should be matched to the specification for accuracy.

Weathering SteelAluminum

Aluminum is the most versatile material, well-suited for almost any environment. Painted aluminum bases have a durable spatter coat finish but do require cleaning and paint touch-ups over time.

Alternately, aluminum bases can have an unpainted, hand-sanded finish which has a silvery textured look. Sanded aluminum is ideal for marine environments and is a great low-maintenance material.

Weathering steel is idea for natural settings where general maintenance is difficult.

Weathering steel bases can last well over 15 years but are not recommended for use in salty marine environments.

New weathering steel arrives black with silver patches around weld joints. Over time the surface will change to a uniform rust brown. This takes 6+ months depending on humidity and precipitation.

Once the surface is fully weathered, rust will not rub off or leak onto the ground.

Galvanized Steel

Galvanized steel is not recommended for exhibit frames due to tight tolerances and the potential for warping.

It maybe used for base legs and mounts in marine environments as well as for trailside bases.
