Galvalume Steel - Strong the stone coated steel roofing sheets
Coating composition is 55% aluminum in weight ratio (80% surface volume ratio), 43.4% zinc, and 1.6% silicon. All Sangobuild® roof products are manufactured from alu-zinc steel which has shown in tests to last 6-9 times longer than ordinary galvanized steel roofing products.
#Roof Tile Sheet Aluminium# This is achieved by protecting the stee! core with zinc, which is itself protected by an aluminium barrier. (It's not PPGI Galvalnized, but PPGL Galvalume, which is more durable with extreme weather condititons resistances)
Acrylic Glue
You may use the best stone chips in the world but if your adhesive is weak, you stand no chance. Your stone chips will definitely flake off.
Sangobuild's acrylic coat can remain a class apart from all competition. If the acrylic coat is too thin, it won't adhere as well.
The key property required of any roof coating material is durability. Durability implies resistance to the effects of UV
degradation from the sun.
Stone Chips - Why SANGOBUILD stone coated Roof Not FADED, not what you Think!
There are two kinds of stone chips in the market.
One is pre-painted stone chips; this is the use of paints to coat natural stone.
These chips are very bright mostly when new! But the lifespan is limited to about 2-3 years. Fading is visible after the first few weeks past installation. Other manufacturers use painted stone which quickly changes color due to UV and comes off easily due to low-quality basecoats.
The other chip is sintered stone chips; it is the most advanced technology of the chips for stone coated roofing sheets. Sintering is the process of compacting and forming a solid mass of material by heat or pressure without melting it to the point of liquefaction. Sintered stone gives a guarantee of beyond 20 years on color retention. We also offer CL Rocks from French; We offer a guarantee of at least 20 years no fading, no color change.
