Has to be wood for my show tanks,its a log cabin so pine stands look best in the rustic setting.If I had a welder Id make steel racks for the fishroom
Jovial;787949; said:People normally associate corrosion with rust (iron oxide) but there are many types of corrosion that are much more threatning to metal that remain unseen. Corrosion occuring along the grain boundaries is called intergranular and is much more serious than surface corrosion. When subjected to cyclic stress or constant loading it will fail. Fatigue corrosion and a few others remain invisible unless specific techniques are used, i.e eddy current or ultrasonic NDI. You will never know until the wing breaks off but then its too late. Lost of aircraft mishaps from corrosion. So although the surface my look fine its the structural integrity of the metal along the grain boundaries that is jeopardaized and usually not noticed until its under a load. I think most stands made of steel are plenty strong and will never fail for fresh water applications and maybe saltwater as well.
Automobile panels usually rot from the inside out, so what is seen on the surface when the paint starts to bubble is usually much worse beneath. Like a cancer.

canucksfan1;794521; said:What would u guys suggest someone use to seal the steel??? My tank has a steel bottom on it and was used for a salt water tank (pretty stupid if u ask me) but it's got a decent bit of surface rust on it it's gunna be ground down and them sealed but i don't know with what??? I would buy a pice of glass or sumthin but don't have the cash (it's 7 feet by 3.3) and the steel is still very strong it was only used for a short time and then stored and thats where i picked it up (for free)
