Rectangular Tubing

Rectangular or square shaped tubing is commonly used in many different areas like constructions of architectural features and trims, door or window framing, furniture, decks and porches, lean-to’s, exercise equipments, frames for canvas or plastic sheeting in deck-chairs, conveyor belts, escalators, railings, etc.

The angular shape makes it easy to install and transport as the tubes can be stacked easily without danger of them rolling off. Many industrial, marine, automobile and agricultural equipment manufacturing facilities use large quantities of rectangular tubing. This tubing is also used extensively for decorative and ornamental purposes indoors and outdoors. Latest design trends in transparent acrylic and plastic rectangular tubing are being used in lighting and landscaping of gardens, theater and dance events etc.

Rectangular tubing also finds use in the computer manufacturing industry, military and aerospace industry, etc where structural strength is important. Trailer beds, truck and rail frames and carriage frames can be constructed with high-quality steel rectangular tubing.

Generally, rectangular tubing is available in most metals like aluminum, stainless steel, cast-iron, galvanized or anodized aluminum, copper, carbon steel and alloys like bronze. These metals can be polished, electro-plated or coated with a variety of materials like chromium or zinc to give a good finish. When used in outdoor applications, they may be heat-treated to prevent weathering and expansion or contraction, to resist rust and corrosion and to conform to construction industry safety standards. Materials like plastics, PVC and acrylic are used in lightweight applications, chemical and pharmaceutical industries, food and beverage industries etc and are also suitable for outdoor displays and shelving as they do not get damaged due to exposure to weather, aggressive chemicals and solvents. Acrylic is also hard and scratch-proof while providing visibility and transparency.

Connecting or joining lengths of rectangular tubing is done by means of either heat-sealing, welding, adhesives or the use of rectangular connectors. The connector or coupling should be a perfect fit otherwise it may lead to structural weakness. The shape makes the operation relatively simpler and installing rectangular tubular structures is easier than round ones. Rectangular tubing is also easier to cut. If the thickness is less, you can even use a hand-saw or power-tool at home after marking the spot correctly to get a sharp, even cut. If you’re cutting steel or metal, it’s best to use some lubricating substance to avoid heating and also prevent fine dust from flying out and causing injury.
