Size

Square Hollow Sections (SHS)

• SHS can range in size from 12 mm x 12 mm to 300 mm x 300 mm.
• SHS can be made of stainless steel.
• Some examples of SHS sizes include:
* 20 x 20 x 2 mm
* 25 x 25 x 2 mm
* 30 x 30 x 2 mm
* 40 x 40 x 2 mm

Rectangular Hollow Sections (RHS)

• RHS can range in size from 26 mm x 13 mm to 400 mm x 200 mm.
• RHS can be made of mild steel.
• Some examples of RHS sizes include:
* 40 x 25 x 2 mm
* 50 x 20 x 2 mm
* 0 x 25 x 2.5 mm
* 50 x 30 x 2.5 mm

Benefits of using SHS and RHS in Construction

1. The tubular form of SHS and RHS gives a better strength to weight ratio compared to other types of steel, concrete or timber.
2. Better strength to weight ratio helps in building more aesthetically pleasing, airey and lightweight structures with reduced material usage and greater spans.
3. Since there is less usage of material, there is less wastage and even if it is there, it can be fully recycled.
4. Less construction times which means less impact on surrounding communities.
5. Lightweight nature of SHS enables extensions to be built to existing buildings without overloading their foundations.

Types of SHS RHS

Hot-finished RHS

These are made by heating the steel to high temperatures and then passing it through rollers to form the desired shape. The resultant product has a smooth surface and is relatively uniform in shape and size.

Cold-formed RHS

These are made by bending flat steel sheets into a desired shape and size without heating the material. They are processed in a series of steps that involves rolling, bending, and cutting, resulting in a lightweight and cost-effective product.

Welded RHS

These are made by welding two or more pieces of steel together to form a rectangular shape. They are used mainly in construction projects where strength and durability are required.

Seamless RHS

These are made by extruding steel through a die to create the desired shape with no welds or joints. The end product is strong, durable, and has a smooth surface finish.

FAQ

Q: What is the difference between shs and rhs?

A: The term RHS stands for Rectangular Hollow Section. RHS is the most prevalent term and is generally accepted for describing square hollow section as well, which is technically incorrect. The correct term for square tube is SHS which stands for Square Hollow Section.

Q: Is shs stronger than rhs?

A: SHS, with a symmetrical shape, delivers uniform strength on all sides, offering high resistance to torsion and twisting. RHS, preferred for its superior bending strength and greater load-bearing capacity, excels in tasks where the load is mainly in one direction.

Q: Can shs be used as a beam?

A: Square Hollow Sections (SHS) are often used for columns, however similarly to RHS sections, they are not often used as beams due to their shape that makes it difficult to bolt to other beams and vice versa.

Q: Where do we use RHS SHS sections in formwork practice?

A: Structural Requirements:
RHS is used for high-load applications like beams and bracing systems.
In regions where symmetry is required with uniform weight distribution, choose SHS.
For dynamic constructions like trusses and pipelines, go with CHS.

Q: What grade steel is RHS?

A: Orrcon Steel distributes and manufactures rectangular hollow sections ranging from 50x20mm to 400x300mm. * Our Rectangular Hollow Sections are manufactured to the Australian Standard for structural steel hollow section AS/NZS 1163 and cover steel grades C250L0 and C350L0.

Q: What is the strongest steel profile?

A: I-beams, also known as universal beams, are among the strongest and most widely used steel beams in construction. Their signature “I” shape – with a vertical web and horizontal flanges – gives them excellent strength-to-weight ratios, allowing them to support heavy loads across long spans.

Q: What is stronger square tubing or rectangular tubing?

A: This is due to the formula, which shows that rectangular tubes have a bending strength that is about 15% higher than that of square tubes. Stiffness is a crucial indicator for measuring the performance of structural materials.

Q: Is the C channel stronger than the RHS?

A: RHS Columns: Stronger & More Costly.
RHS (whichs stands for Rectangular Hollow Section) is a fully enclosed steel column with four sides. The is also thicker than C-Section, giving it much more structural strength.

Q: How do you connect timber beam to SHS?

A: Connection is established with the use of a steel fin plate, welded to the SHS steel column and inserted into a slot cutout into the timber beam, using regular through bolts. Timber beam is spaced about 10mm away from the steel column to ensure flexibility and moment release at the joint.

Q: What is the difference between RHS and SHS?

A: SHS steel stands for square tube. RHS steel stands for rectangular tube. These two specific types of steel hollow sections are designed to provide a combination of strength and functionality which makes them suitable for a wide variety of applications.

Q: What is the blue coating on RHS steel?

A: Corrosion Protection: The blue primer finish applied to our RHS sections provides effective corrosion protection, making them suitable for both indoor and outdoor use. This protective coating enhances the longevity of the steel sections, reducing the need for frequent maintenance.

Q: What is the thickness of RHS?

A: RHS's are described by their depth, width and wall thickness. An example is a 200 x 100 x 8 RHS, which is 200 mm deep, 100 mm wide and the wall is 8 mm thick. Hot rolled RHS's are made at the mill as one piece, whereas cold formed RHS's are made of a flat sheet rolled at right angles and welded.

Q: What is the purpose of the RHS?

A: The RHS' founding purpose was to improve the science, art and practice of horticulture. We continue this with ground-breaking horticultural research, improving the health and people and nature.

Q: What is the difference between UB and RHS?

A: A UB (universal beam) or UC (universal column) is the most efficient use of material which is why we use them wherever possible. The main advantage of an RHS is in torsion when there are eccentric loads, such as the outer leaf of brickwork like the image below.

Q: What is a SHS beam?

Q: Is shs mild steel?

A: From hollow sections to universal beams, steel is one of the most widely-recycled materials. SHS, RHS and CHS steel products are one of many eco-friendly mild steel products to consider if you are conscious of environmental impact.

Q: What are the advantages of RHS?

A: Advantages of RHS steel
Rectangular Hollow Sections (RHS) offer a superior strength-to-weight ratio, making them an excellent choice for load bearing applications. The closed shape of RHS also contributes to increased rigidity, ensuring stability in various structural designs.

Q: What is the RHS rule?

A: If the hypotenuse and a side of a right- angled triangle is equivalent to the hypotenuse and a side of the second right- angled triangle, then the two right triangles are said to be congruent by RHS rule.
