CHS: Based on the surface treatment of Rectangular Hollow Section and Square Hollow Section, the surface treatment of the Hollow Section including engrave, both ends threadings, one with caps, another with caplings.
Packing ways: Nylon belt packing
Application:
Hollow sections are versatile and widely used in various industries such as Structural Applications, Architectural Applications and Agricultural Applications.
Structural Applications:
Hollow sections are commonly used in construction for building frames, trusses, and columns. These sections provide a high strength-to-weight ratio, making them ideal for structures that need to support heavy loads while remaining lightweight. They are also easier to fabricate, transport, and install than solid sections, resulting in cost and time savings. Hollow sections are used to build bridges, stadiums, factories, airports, and other large structures.
Mechanical Applications:
Hollow sections are widely used in mechanical engineering for their stiffness, durability, and resistance to deformation. They are used in the manufacture of machinery, equipment, and vehicles such as cranes, excavators, trailers, and bicycles. Hollow sections are also used in the production of hydraulic and pneumatic cylinders and components. Their uniform cross-sectional geometry makes them suitable for welding and other joining techniques, which adds to their versatility.
Architectural Applications:
Hollow sections are increasingly being used in architectural applications for their aesthetic appeal, versatility, and corrosion resistance. They are used in the design of facades, partitions, railings, and even furniture. Hollow sections can be finished in different colors, textures, and patterns to complement the building's design. Their corrosion resistance makes them suitable for outdoor use, where they can withstand harsh weather conditions.
Agricultural Applications:
Hollow sections are commonly used in agriculture for their strength, durability, and corrosion resistance. They are used in the construction of farm buildings, fences, and gates. Hollow sections are also used in irrigation systems as pipes and channels. Their resistance to corrosion and chemical attacks makes them suitable for use in harsh agricultural environments.
