Plugs for square pipes

Caps for square pipes from "Nova Kovka"

Plastic caps for square pipes are a small but important part of any metal structure made of a profile pipe. They close the open end, protect the metal from the inside from moisture, dust and dirt, hide sharp edges and give the finished product a neat, finished look. The "New Forging" catalog contains caps for all common square profile sizes - from 15×15 to 80×80 mm.

Why without a cap, a profile pipe rusts faster

The open end is the weakest point of a profile pipe. Through it, water, condensate, dust and even insects get inside. Moisture remains in the cavity and gradually destroys the metal from the inside: first rust spots appear near the end, then through corrosion. The cap for a square pipe closes this way and performs several functions at once:

— seals the end of the profile from water, dust and dirt;
— slows down corrosion and extends the service life of the product;
— hides the sharp edges of the metal—safer for people and animals;
— gives the structure a neat, finished look;
— protects internal anti-corrosion coating against mechanical damage.

It is especially critical to use plugs on street structures: gates, fences, gates, canopies, railings, garden furniture and decorative elements that are constantly in contact with precipitation.

Plastic plugs for a profile pipe: advantages

The most popular option is plugs made of impact-resistant plastic (polyethylene or PVC). They are light, do not rust, do not require welding or tools: the plug is simply inserted into the end of the pipe and tightly fixed thanks to the stiffening ribs. They are made in different colors - most often black and gray, which go well with painted metal. For a complete finish of the metal structure, we recommend supplementing the installation with fasteners and anti-corrosion paint from our catalog.

How to choose a cap of the right size

The main parameter is the outer section of the profile pipe: 15×15, 20×20, 25×25, 30×30, 40×40, 50×50, 60×60, 80×80 mm and other standard sizes. It is also important to consider the thickness of the pipe wall: the internal fitting size may differ by 1-2 mm. A properly selected plug enters the pipe with little effort and is securely held without additional fixing — it does not fall out due to vibration or temperature changes. If you need a non-standard size, contact our manager and we will select an analogue or order the required standard size.
