Hollow Sections

Hollow Structural Sections (HSS) in Malaysia: SHS, RHS & CHS

Hollow Structural Sections (HSS) are high-strength steel profiles characterized by their hollow tubular cross-sections. While the term "HSS" is a global engineering standard, these versatile members are commonly referred to in the Malaysian construction industry as Square Hollow Sections (SHS), Rectangular Hollow Sections (RHS), and Circular Hollow Sections (CHS).

At Oh Tung Sang (OTS) Hardware, we provide premium HSS profiles that conform to international structural codes, offering a superior balance of strength, weight, and aesthetic appeal.

The Benefits of Designing with HSS

HSS is the material of choice for architects and structural engineers due to its unique geometric properties:

• High Strength-to-Weight Ratio: The hollow core significantly reduces the weight of the member without compromising its load-bearing capacity, leading to cost savings in transport and foundation design.

• Torsional Resistance: The closed-loop shape of HSS provides exceptional resistance to twisting (torsion) and lateral buckling, making it safer for long-span structures.

• Uniform Strength: Unlike open beams (like I-beams), HSS offers consistent structural properties across multiple axes, ideal for multi-directional loading.

• Aesthetic Excellence: With smooth surfaces and rounded corners, HSS is perfect for exposed structural steelwork (AESS) in modern buildings, airports, and stadiums.

Available Shapes & Applications

We supply a wide range of HSS profiles tailored for different engineering needs:

• Square Hollow Sections (SHS): Often used for columns, posts, and symmetrical frames where uniform strength is required.

• Rectangular Hollow Sections (RHS): The preferred choice for mechanical frames and architectural trusses due to its flat surface, which simplifies joining and welding.

• Circular Hollow Sections (CHS): Ideal for aesthetic columns, handrails, and offshore structures where wind or water resistance is a factor.

Precision Processing at OTS Hardware

Leveraging our 80,000 sq. ft. manufacturing capacity, we don't just supply raw HSS. We offer specialized processing to save you time on-site:

• CNC Laser & Plasma Cutting: Get your hollow sections cut to exact lengths with precision-matched bolt holes.

• Bandsaw Cutting: Clean, straight, or miter cuts for immediate assembly.

• Custom Fabrication: Professional welding and bending to transform HSS into ready-to-install structural components.
