The overall strength of any steel structure is only as solid as it's weakest link. In most cases, any possible compromise in strength is the result of rust damage. Over time, rust can eat away at improperly treated steel trusses, especially in the welds. Taking the appropriate preventative actions in the manufacturing process of steel trusses will guarantee long life and durability. To ensure the life-long structural integrity of every building we erect, all metal components and trusses are hot-dip galvanized after being welded.   

The process of hot-dip galvanizing consists of coating the metal with a thin layer of zinc. This protective zinc layer increases the metal's resistance to rust corrosion. It is very important that the hot-dip galvanizing of metal occurs after the welding process is complete. This allows the zinc to thoroughly coat the inside and the outside of the steel tubing, ensuring maximum protection.
