TESTS ON PAINTING METAL-SPRAYED STRUCTURAL STEEL

OVER 400 CHANNEL SECTIONS AND OVER 100 FLAT SPECIMENS HAVE BEEN METAL-SPRAYED, PAINTED AND EXPOSED TO VARIOUS ENVIRONMENTS IN ORDER TO CONFIRM THAT GOOD PROTECTION, WITHOUT UNDULY SHORT PAINT LIFE, CAN READILY BE ACHIEVED BY THE USE OF COMPOSITE COATINGS OF SPRAYED ALUMINUM OR ZINC AND A WIDE VARIETY OF PAINT SCHEMES. AFTER 2 YEARS, MOST OF THE TEST MATERIAL WAS STILL IN GOOD CONDITION, BUT THERE WERE SOME FAILURES. THE PROBABLE CAUSES OF OCCASIONAL FAILURES FOUND IN PRACTICE ARE HIGHLIGHTED AND ARE ATTRIBUTED TO INCORRECT SCHEDULES OF OPERATIONS OR INJUDICIOUS SELECTION OF PAINTS. IN PARTICULAR, WEATHERING PRIOR TO COMPLETION OF THE FULL PAINT SCHEME SHOULD BE AVOIDED WHENEVER POSSIBLE. RECOMMENDATIONS ARE MADE AS TO HOW TO ENSURE GOOD PAINT LIFE OVER SPRAYED METAL COATINGS. /AUTHOR/
