Balcony railings are aesthetic and protective features along the outer edge of a balcony, constructed from alloy tubing through welding or assembly. Common low windowsills are approximately 0.5 meters from the ground; adding a 0.4-meter railing or fence close to the inner wall will certainly meet the required safety standards. If the windowsill is too large, such as a bay window, children often stand on it to look out, and users must also stand on the windowsill to open the window. In this case, the railing attached to the windowsill should be at least 0.9 meters high.
Materials include: round tubing (∮16, ∮19, ∮22), square tubing (22, 25), color-coated steel (internal and external hot-dip galvanized seamless steel), and color-coated aluminum (1.2 mm seamless aluminum-magnesium alloy profile).
