A lightweight material boasting a high strength-to-weight ratio, aluminum is resistant to moisture, corrosion, and flames. Its malleability allows for the creation of bent edges or bends in panels, making it perfect for transportation, automotive construction, and high-tech applications.

ABS, Fiberglass, and FRP (Fiber reinforced Plastic)

Whether smooth gel-coated or embossed for added reinforcement, FRP offers lightweight construction, excellent impact resistance, and the ability to produce seamless panels. Moisture and corrosion-resistant, FRP comes in various textures and gloss levels, making it ideal for transportation, marine, and construction uses.

Stranded Polypropylene

Available in diverse thicknesses, sizes, and finishes, stranded polypropylene delivers incredible impact resistance, making it perfect for high-abuse areas such as trailer and van interiors. While seamless sheets are suitable for external applications, they lack automotive finish quality.

Rubber and Vinyl

Ideal for flooring and decking, rubber and vinyl skin materials come in an extensive range of patterns, textures, and colors, catering to both decorative and industrial needs.


Renowned for its strength, steel is the go-to skin material in many applications, though it is heavier than other options. Thin gauge steel serves as a cost-effective, high-strength solution when weight is not a concern.


Offering a low-cost option where weight is not critical, wood is commonly used in interior applications requiring mechanical fasteners throughout the panel.
