Few environments are as challenging as the ocean or the sea. Humidity oxidizes most metals and salt water speeds up the electro-galvanic corrosion between different metals. Great care is therefore necessary when selecting the products and materials they are made of.
METU offers many different types of access doors to cover most applications. The materials range form galvanized steel to stainless steel V2A and V4A, as well as aluminum.
V2A = 1,4301 (ASTM 304)
V4A = 1,4404 (ASTM 316)
