Looking for reliable support solutions? Check it out now!

    Main article:

    In industrial plants, large warehouses, bridges, equipment platforms and even modern buildings, steel structure columns and legs play a crucial role as “bones”. They directly bear the structural loads and ensure overall stability and safety. Exquisite processing technology is the fundamental guarantee for the performance and life of these key components.

    We specialise in the design and manufacture of all kinds of steel structure columns and legs, and strictly control every step from raw materials to finished products. Below are some of our finished columns and legs, showing the diversified structural forms and excellent processing quality:

    I. Core load-bearing: demonstration of main pillar types
    H-beam struts:

    Finished product: [Insert high-quality picture showing several finished H-beam columns of different sizes and surface treatments (e.g. after sandblasting and rust removal or after priming), neatly stacked, highlighting the straightness of the flanges and webs].

    Characteristics and processing points: The most commonly used form of pillar, excellent mechanical properties of the cross-section. Processing focuses on accurate undercutting to ensure the length, end milling to ensure that the contact surface is flat, drilling holes (holes for ground bolts, holes for connecting plates) in precise positions, and strict control of welding deformation (such as necessary stiffening plate welding). It is suitable for frame columns of all kinds of plants.

    Box columns:

    Finished drawing: [Insert high-quality picture: Show box columns of rectangular or square cross-section, showing the body, details of the footings, internal bulkhead welds (if any) and the top joint end plate]

    Features and Processing Points: Closed cross-section, great torsional rigidity, high bearing capacity, neat appearance. Processing technology is complex, involving four pieces of steel plate precision discharging, bevel preparation, assembly and positioning, internal partition welding (to ensure spatial rigidity), the main body of the four main weld welding (usually using submerged arc welding to ensure quality and efficiency), end milling and hole opening. Mostly used for high-rise, large-span or critical parts with particularly high loads.

    Tubular columns/tubular columns:

    图片[1]-各类型支柱支腿类型钢结构加工成品展示 - cndlfh.com-cndlfh.com

     

    Finished drawing: [Insert high-quality picture: showing a large-diameter or thick-walled round tube column, highlighting its annular cross-section, which can show details of the legs with flanged ends or directly welded]

    Features and Processing Points: Good hydrodynamic performance (wind resistance), simple and modern appearance. Processing needs to ensure the verticality of pipe cutting, smooth end face treatment, high accuracy of flange drilling (to ensure smooth bolt connection), reliable quality of ring seam welding (to control deformation). Commonly used in structures requiring better landscape effect or significant wind load, such as canopies, curtain wall support columns, decorative structures.

    Lattice struts:

    Finished drawing: [Insert high-quality picture: showing a lattice column made of steel sections such as angles and channels connected by splicing plates or strips, highlighting the limb and connection system]

Vertical welding of the legs (profiles or combined sections) and the base plate is the key, and must ensure that the angle is absolutely 90 degrees, and the welding strength is sufficient to avoid deformation. The tolerance of the drilling position of the base plate is strict.

    Flange connection type:

    Finished product: [Insert high-quality picture showing the finished product with flange welded to the end of the leg, the bolt holes in the flange are clearly visible].

    Features and processing points: Convenient for on-site bolting installation and dismantling. Flange flatness is required to be high, and the bolt hole position accuracy is required to be extremely high to ensure smooth docking with pre-embedded parts or foundation components. The axis of the legs should be perpendicular to the plane of the flange.

    Adjustable legs:

    Screw adjustable type:
