6000 - 12000 mm High Strength Pultruded Profiles China Wholesalers Fiberglass Pipe Square Tube/FRP Pultruded Square Tube
FRP Square Tube
Square tube is a name for square tube and rectangular tube, that is, steel tube with equal and unequal side lengths. It is made by rolling steel strip after processing. Generally, the steel strip is unpacked, flattened, curled, and welded to form a round tube, which is then rolled into a square tube and cut into the required length. It is also called square and rectangular cold-bent hollow steel, abbreviated as square tube and rectangular tube, with codes F and J respectively.
The main difference between it and steel pipe is that one is round and the other is square. The materials used to make square tubes are different, so the uses of the finished square tubes are also different. The manufacturing process of square tubes and round tubes is similar. They are all unpacked, flattened, curled, and welded to form square tubes, and then cut into different lengths according to needs. Square tubes can be divided into structural square tubes, decorative square tubes, architectural square tubes, mechanical square tubes, etc. according to their uses.
Used in engineering construction, glass curtain walls, door and window decoration, steel structures, guardrails, machinery manufacturing, automobile manufacturing, home appliance manufacturing, shipbuilding, container manufacturing, electricity, agricultural construction, agricultural greenhouses, bicycle racks, motorcycle racks, shelves, fitness equipment, leisure and tourism products, steel furniture, various specifications of oil casing, oil pipes and pipeline pipes, water, gas, sewage, air, heating and other fluid transportation, fire fighting and brackets, construction industry, etc.

Good anti-torsion ability: Due to its rectangular shape, it is more stable than round tubes when twisted.
Relatively straight surface: The square tube has a relatively neat and straight shape, and will not bend or deform, which can ensure a better decorative effect.
Easy to connect with other components: Due to its relatively straight shape, square tubes are easier to connect with other components.
Square tubes are lighter in weight when the bending and torsional strengths are the same. They are an economical cross-section steel. Using square steel tubes to manufacture annular parts can improve material utilization, simplify manufacturing processes, and save materials and processing time.
