Roofing
Prepainted galvanized steel sheet and prepainted GALVALUME® Coated Sheet from
U. S. Steel make exceptionally attractive and durable roofing (whether conventional or standing
seam). Both products can be manufactured in a variety of standard profiles and shapes
including architecturally unique profile designs. A structure can have a roof that looks
like shingles, shakes, clay tiles or new special designs, but have
all of the advantages of prepainted steel. Modern paint systems offer exceptional
resistance to chalking and fading, allowing the original color and gloss to last for a long time.
These new and improved paints can be tailored to meet the appearance and performance expectations
for any facility whether it is new or being renovated.
U. S. Steel has produced both galvanized and GALVALUME® Coated Sheet for many
years, gaining a time-proven record of supplying high-quality, coated sheet products that
meet the needs of the construction industry. U. S. Steel has been producing galvanized
steel sheet for the requirements of this industry for more than 50 years. As the use
of galvanized sheet changed from unpainted to prepainted for most construction industry
applications, U. S. Steel was able to provide the improved surface quality required for
prepainted products. Prepainted galvanized steel sheet not only looks more attractive,
but it also provides greatly enhanced service life compared to the unpainted product.
GALVALUME® Coated Sheet, which U. S. Steel has produced since 1982, has an aluminum-zinc
alloy coating to provide both galvanic and barrier-layer corrosion protection. For many
applications, especially those that require good long-term performance in corrosive environments,
U. S. Steel's warranted prepainted GALVALUME® Coated Sheet has become the product
preferred by many users.
Today, with technically sophisticated organic paint coatings applied by the
prepainting process, galvanized and GALVALUME® Coated Sheet products enclose and
protect structures of all kinds while giving them architectural grace.
