Why does the iron window have a rounded “crotch” downwards? 90% of people don’t know the real secret!

can put a book, a cup of coffee, or even sit and lean your back on it. Like a small chair. Water drainage: The round design keeps the winter water from gathering on top of the iron and manages the ruin. Slide down slowly and do not push the iron quickly.3. Why are people surprised?
Because we see it as an old taste. But our ancestors were good at design. Darrow is a singular thing in which: beauty + security + utility. It’s like a flat “grillage” now. Conclusion: The round curve = a miniature balcony of the old people. Intelligence before it was taste.
