Steel is an alloy that is made by combining iron and another element, usually carbon. Carbon steel contains 0.2% to 2.1% by weight, depending on the grade desired. Carbon and other elements like manganese, chromium, vanadium and tungsten are used as hardening agents in the process. Proponents of steel trailers in the steel vs aluminum trailer debate are quick to point out that steel has a longstanding reputation of being one of the toughest common alloys, while aluminum is more commonly known as pop can or foil material.
Steel trailer manufacturers have yet to come up with a process that makes steel as rust-resistant as aluminum. When considering aluminum vs steel trailers, you have to consider that steel trailer manufacturers have a galvanizing (dipping process) and galvannealing process (electrochemical process) which coats steel with a protective layer of zinc in order to retard corrosion. This galvanizing and galvannealing process is good but also expensive, so most steel trailers manufacturers only galvanize the skin of the trailer to keep costs low. The galvannealed steel trailers are often painted. Another process is the powder coating (baked process) of the steel. Over time, the elements and gravel can penetrate the paint, powder coat or the protective zinc layer. Without the proper maintenance and recoating of chips and scratches, this rust can destroy the deck that supports your precious cargo. The corrosion weakens the undercarriage and decreases the strength of the once strong steel materials. Why let rust literally eat away at your investment, your trailer’s appearance and your time?
