At water fed pole, we take safety seriously. That is why we only offer stainless steel tank frames with our systems. Stainless steel is the only material capable of withstanding the force of an impact when a baffled tank is full. Do not suffer cheap imitation frames constructed of aluminium, or cheap straps. Only a TIG welded stainless steel frame bolted through the chassis is able to protect you and other road users. Stainless Steel, unlike cheaper materials, does not corrode or rust and will not scratch and mark like aluminium. When it comes to safety do not skimp, invest in a quality stainless steel frame, which gives you the best possible chance in an accident.
