Square Hollow Sections (SHS)
The Square Sections enhance the reliability of the structure. These are manufactured using graded steel in compliance with set international standards. The square sections are used as support in automotive industry, transmission tower plants, machinery industry, construction industry and many others. These sections are made using high grade steel metal in compliance with international standards. The square section holds superb tensile strength and is rust resistant with ability to offer long working life. The sections are tested on various parameters, which are tensile, bending, flattening and other strengths.
Rectangle Hollow Sections (RHS)
The Rectangular Sections are constructed using finest steel. These are preferred for their robustness. The rectangular section has precise dimensions and accuracy, which is one of the trademarks of our high-grade manufacturing abilities. It is tested on several international standards, where tensile strength, flattening, bending and drift expansion. It is preferred in several industries such as furniture industry, construction industry, automotive industry and many more.
Circular Hollow Sections (CHS)
The Round Hollow Sections are accurately designed and are used in several industries. The sections are manufactured using prime grade steel, which offers supreme rigidness and corrosion resistance. Circular hollow sections possess superior tensile strength, light weight and high impact strength. Further, the hollow sections have better weld ability, better resistance to surge pressure and are free from chemical contamination.
Features
- Good weld-ability
- Supreme resistance to torsion
- Cost beneficial /Economical solution. Easily executed direct joints, shorter construction times and easy maintenance, are the results of a correct design and the guarantee of a competitive delivery date and price.
- High impact strength
- Corrosion resistant
- Supreme tensile strength
- Dimensional accuracy
- Easy to transport
- Aesthetically looks good
- Lighter and more diaphanous structures. Pieces of greater length with fewer joints
- More slender supports. Fewer sections, which can be reduced even more with the use of tubular sections filled with concrete.
- Expressive capacity. Circular, square, rectangular sections, a range of wall thicknesses for every dimension of tubular section, absence of sharp edges,etc. These are the elements that provide innovating, wide ranging possibilities forarchitects and engineers
Application
- Machinery manufacturing industry
- Storage systems
- Transmission tower plants
- Automotive industry
- Construction industry
- Furniture
- Heavy Machine Equipment
- Agricultural Equipment
- Earth Moving Equipment
- Solar Panel & Systems
- Electric Pole’s
Hot Dipped Galvanised Sections (SHS , RHS , CHS)
Above all can also be available in Hot Dip Galvanised form depending on your requirement & quantity. Galvanising will increase the lifeline,durability,strength, rust prevention of the product.
