Aluminum is one of the more common substrates used on cargo, livestock and semi-trailer roofs. Sheets of aluminum are aesthetically pleasing with a hard surface that helps reinforce the trailer and protect it from environmental factors and low-hanging tree branches.
However, roofs and sidewalls manufactured with aluminum also can be more vulnerable to oxidation and stress cracks. The adhesives and sealants you use can add significant protection and durability to the aluminum sheeting to strengthen your structure.
