A real chat from a customer, the customer is looking for photovoltaic bracket fasteners, due to the limited budget customer found a supplier with 50% lower price, the customer will do salt spray test with our products and peer products, after 23 hours of testing it is obvious that the appearance of the same bimetallic material, another supplier's fasteners have rusted, but HQ Mount solar fasteners due to the higher nickel content, the surface does not appear very serious rust. Many conventional 304 solar hooks on the market are made of scrap, so the price of those suppliers is very low, but their products will rust quickly, here we would like to say to the majority of customers Please always trust testing results, the solar system we are building is supposed to stand at least 25 years.
