EN 10219 square tube is welded from strip steel or plate after crimping, it is widely used in steel structure plant, warehouse, bridge building, intelligent greenhouse, civil construction and other fields.

The EN 10219 specification is segregated into two parts. While part 1 covers the Technical delivery conditions of the en 10219 pipe. Part 2 covers its dimensions, tolerances, as well as its sectional properties. Cold formed welded structures produced under this standard are available in shapes like square, circular, or rectangular forms.  

The hollow sectioned en 10219 square tube typically does not require subsequent heat treatment. Grade s235jr steel pipe designated with the letters JR indicate the qualities with specified impact properties at room temperature or its specified impact properties at a temperature of 0℃. Whereas the numeric value in the term EN 10219 S235JR is indicative of its minimum yield strength, which in this case stands at about 235 N/mm2.

EN 10219 rectangular tube is welded from strip steel or plate after crimping, it is widely used in steel structure plant, warehouse, bridge building, intelligent greenhouse, civil construction and other fields. The rectangle dimension range is 40×20 to 400x200mm. In length, it is available as 6 to 12/18 m.

Cold Formed EN 10219 S355J0H Rectangular Hollow Section is inspecting product on various parameters. This Rectangular Hollow Section is obtainable through means of solutions as per the drawings and designs have given by the clients. The industries like infrastructure development, petrochemicals, boiler manufacturers etc find this grade Rectangular Hollow Section pipe ideal for fulfilling application needs. Moreover, these pipes are factory made by making use of excellent quality of materials and technology of cutting edge under the supervision of experts.

EN 10210 rectangular tube is welded from strip steel or plate after crimping, it is widely used in steel structure plant, warehouse, bridge building, intelligent greenhouse, civil construction and other fields.

BS EN 10210 Pipes Material is made up of a low carbon steel material that has 0.22% carbon, silicon, 1.6% manganese, sulfur, phosphorus and other elements in trace amounts. Lai is a leading EN 10210-1 Pipes Manufacturer and supplier.

Black annealed square tube is welded from strip steel, after pickling, the process in turn is cold-rolled, divide into strips of corresponding width according to the model, annealed, air-dried for 24 hours, and rolled into shape. It is widely used in furniture, fence, roofing, interior decoration, building curtain wall, etc. Black annealed square tube reduces hardness, it is not easy to break, so it is easier to secondary processing and deformation.

EN 10210 square tube is welded from strip steel or plate after crimping, it is widely used in steel structure plant, warehouse, bridge building, intelligent greenhouse and other fields.

ASTM A500 rectangular tube is welded from strip steel or plate after crimping, it is widely used in steel structure plant, warehouse, bridge building, intelligent greenhouse, civil construction and other fields.

Structural tubing per ASTM A500 is tubing produced and used for structural applications. Standard strength requirements of the tube help dictate applications for which certain tubing is most appropriate. Structural tube is often referred to as hollow structural sections or HSS. Structural Tubing, especially rectangular sections, are commonly used in welded steel frames where members experience loading in multiple directions.
