2023 the new Zupapa Trampoline employs upgraded techniques and technology to make products have a longer life. Hot-dip galvanizing process makes the Zupapa trampoline frame and net pole last for decades. UV absorber uv-9 was added to material, pad, mat and net, to extend the trial life. What's Hot-dip galvanization? Hot-dip galvanization is a form of galvanization which makes the rust resistant time 5 times longer than common galvanization. It is the process of coating iron and steel with zinc, which alloys with the surface of the base metal when immersing the metal in a bath of molten zinc at a temperature of around 840 °F (449 °C). When exposed to the air, the pure zinc (Zn) reacts with oxygen (O2) to form zinc oxide (ZnO), which further reacts with carbon dioxide (CO2) to form zinc carbonate (ZnCO3), a usually dull grey, fairly strong material that protects the steel underneath from further corrosion in many circumstances.
