Carbon steel is a steel alloy with lowered requirements for metals typical of stainless alloys. While they are more corrosion-prone than stainless steel tubes, carbon steel tubes are powder-coated to prevent corrosion.
The backbone of your vehicle is its frame. This heavy-duty network of specially-shaped steel beams supports your entire vehicle's weight and performs numerous other functions. Grille guards attach to pre-existing bolt holes at the front end of the frame, tying your guard in with the strongest anchoring point on your vehicle.
Molded polymer running boards are constructed from a high-strength plastic compound that's lightweight and easy to shape, plus more cost-effective than metal. And, when paired with an aluminum base, molded running boards can hold a larger capacity than steel tube models.
Powder coating has become a popular process for treating metal with a uniform color coat that's chip-, scratch- and corrosion-resistant. The process involves spraying metal with fine dry resin particles that are electro-statically charged so that they stick to the surface. The coated metal is then baked at 400° F, melting the clinging particles into a smooth, durable finish. The overwhelming number of powder coat finishes are done in gloss black.
