Perforated Square Steel Tubing

Select connectors based on the larger size rail in the connection.

Perforated square steel tubing. Carbon mild steel perforated metal pipes tubes contain varying hole patterns of different sizes and shapes created by punching presses. Connect multiple rails with brackets or slide one length of rail into the next larger size and bolt together using curved bolt or locking pin connectors. Rails have bolt holes on all four sides. Galvanized perforated square tubes are a36 hot rolled steel or mild steel tubes that have been punched and dipped into a molten zinc coating process.

Steel rails are lightly oiled. Types of hole patterns include round square rectangular scale hexagonal and so on. Perforated steel tubing has the features of corrosion resistance alkali resistance accurate hole. One prominent advantage is its unique telescoping feature.

Galvanized steel rails have good corrosion resistance in wet environments. Hot dipped galvanize hdg can be identified by its crystallization pattern also known as spangle on the surface of the material.
