Global Contract Services manufactures rotationally moulded items on-site, particularly for the aquaculture and agriculture industries. Our range of Global Poly Water Tanks are rotationally moulded in one piece and feature a domed top. The moulding process and ribbed construction provides increased strength. The combination of a straight sided design and lack of joints ensure there are no unnecessary stresses on the tank material and eliminates the likelihood of leaks. All tanks are free of all chemical residues or by-products ensuring that the water stored within them is taste free and completely safe. Global also manufacture Chemical Storage/Industrial Tanks, which incorporate thicker walls. All tanks are covered by a 25 year warranty.
