Asalamualaikum welder friends .. On this occasion we made another tutorial, of course, an unusual tutorial, which is how to install casement hinges on a hollow galvanized iron frame and window. For some people, maybe this hinge can only be used in aluminum or wood material, but for us this hinge welder can be applied in hollow metal, maybe this tutorial is the first one that I looked for on KZfaq, it doesn't exist yet, yeah who knows anyone needs and become a science later on ... Casement hinges we buy in stores with a price of 120 thousand brands from solid, many brands are out there for casement hinges, but we use a solid brand because it's quite strong. The window itself is a classic type window with 8 glass column columns, the weight of the glass is approximately 23kg, so we have to buy casement hinges with 25kg weight specifications and 16inc length. Ok hope that helps .. Greetings Welder #weldertasik #engselcasement #engselcasementbesihollow
