Performance of Steel Without the Weight
Aluminum Mixer Truck Chute with NanoSteel Thermal Spray Coating Provides Longer Service Life
Four-foot steel extension chutes widely used on ready mix concrete trucks weigh approximately 50 lbs. Drivers risk injury on the job from lifting the heavy steel chutes, resulting in a risk of profit loss and additional insurance costs for truck owners.
Aluminum extension chutes weighing approximately 30 lbs are an alternative that can reduce driver injury risks. However, aluminum chutes wear faster than heavier steel chutes and require frequent replacement.
A mixer truck in Ohio was equipped with aluminum chutes to evaluate wear from sliding abrasion and erosion caused by sliding concrete during service. A NanoSteel SHS 7170 TWAS thermal spray coating was applied to a thickness of 0.335 - 0.394 (8.5 - 10 mm) on one chute, which added approximately 2 lbs to the total weight.
Since the aluminum chute will still be at its original thickness when the NanoSteel SHS 7170 TWAS coating wears off, it can be re-coated and placed back in service without any loss to its original thickness. An aluminum extension chute can last almost indefinitely with repeated NanoSteel thermal spray coatings.

NanoSteel Chute After 13 Months of Service
After 13 months, the NanoSteel coated chute has 75% of coating thickness present and the aluminum base is 100% intact
Unprotected Chute Must Be Replaced
NanoSteel coated chute remains on the job while the unprotected chute is severely worn, leaks at the seams and must be replaced
