Why Composites?

The general definition of a composite is a combination of different components or elements.

Relative to the composites industry, that definition becomes “a combination of plastic resin and a fiber reinforcement.”

For Zantho Tools®, think of our non-conductive composite housing as being made from two or more materials that, when combined, are stronger than those individual materials alone.

By using a composite material, our ZAN-35 series of insulated hoist/tensioners are lightweight, durable, non-conductive, and corrosion resistant.

For example, metals such as aluminum or steel are isotropic, meaning they have equal strength in all directions. Composites are anisotropic, meaning they have different properties in different directions.

Specifically, ZAN-35 series are produced with Engineered Structural Composites® (ESC®) an advanced, strong yet lightweight, high-performance material containing carbon fiber and fiberglass reinforcements. ESC® materials are utilized in myriad applications in the toughest environments to meet stringent standards.

Advantages of Composites



High Strength





Composites are non-conductive, meaning they do not conduct electricity. This property makes them suitable for such items as electrical utility poles and the circuit boards in electronics.

Low Thermal Conductivity


Corrosion Resistant


High-Impact Strength


Strength Related to Weight


Design Flexibility


Part Consolidation


Dimensional Stability

Composites retain their shape and size when they are hot or cold, wet or dry. Wood, on the other hand, swells and shrinks as the humidity changes. Composites can be a better choice in situations demanding tight fits that do not vary. They are used in aircraft wings, for example, so that the wing shape and size do not change as the plane’s altitude increases or decreases.
