As a commonly used type in Pipe Handrail Fittings, 131 Base Flange is mainly used for the link between the structure and the ground or platform. There are four holes in the flange to fix it more firmly. 131 Base Flange has a variety of materials, among which malleable steel and ductile iron are the most used. Pipe Handrail Fittings can also undergo surface treatment such as powder coating, hot-dip galvanizing, and electro-galvanizing, among which hot-dip galvanizing is the most used because it not only has a good appearance but also can be used in harsher environments. 131 Base Flange is most commonly used in handrail and guardrail systems and can also be used to fix tables, brackets, etc.
