Circular Hollow Section

Overview

CHS 16mm–76mm are made from high-quality structural carbon steel through seamless or welded fabrication processes. The round geometry ensures uniform strength in all directions, excellent torsional resistance, and efficient load distribution.

Key material properties:

• High tensile and compressive strength

• Uniform load-bearing and torsional stability

• Smooth, round surface profile for aesthetic appeal

• Compatible with welding, bolting, and fabrication systems

• Lightweight relative to equivalent solid steel profiles

These steel tubes are widely used in construction and fabrication projects, allowing engineers to achieve structural efficiency while minimizing steel consumption.

Typical applications in Kenya include:

• Columns and vertical supports in residential and commercial buildings

• Roof trusses, bridges, and industrial frameworks

• Handrails, balustrades, and guardrails

• Canopies, sheds, and carports

• High-load bearing structures for industrial projects

• 
  

2024 National Building Code Compliance

CHS 16mm–76mm conforms to the National Building Code of Kenya (2024) by providing reliable structural integrity for buildings, infrastructure, and fabricated structures. Their use ensures compliance in projects that demand high-load bearing, durability, and safety certification.

Kenyan Environmental Context

Kenya’s climate requires corrosion-resistant, high-strength steel solutions:

• Coastal areas (Mombasa, Malindi): Proper priming or galvanization protects CHS from saline corrosion.

• Urban areas with high UV and heat (Nairobi, Thika): Steel maintains dimensional stability when painted or coated.

• Humid and rainy regions (Kisumu, Kakamega): Circular sections minimize water accumulation, reducing corrosion risk.

Protective coatings such as red oxide primer, epoxy, or galvanization extend service life across these varied environments.

Pros & Cons

Pros

• Uniform strength in all directions

• Excellent torsional and buckling resistance

• Aesthetically pleasing round profile

• Efficient use of steel for structural applications

• Corrosion-resistant with proper coating

• 
  

Cons

• Connections require precision due to round geometry

• Slightly higher fabrication cost than flat sections

• Requires cutting and welding equipment for installation

• 
  

Comparative Analysis: CHS vs. SHS

Square Hollow Sections (SHS) are easier for flat-surface connections, but CHS 16mm–76mm delivers superior torsional strength and uniform stress distribution. For exposed columns, circular trusses, or wind-loaded structures, CHS is often the optimal choice in Kenya.

Frequently Asked Questions (FAQs)

1. What is the size range of CHS available?
BHD offers CHS from 16mm to 76mm diameter to suit various structural requirements.

2. Can CHS be used outdoors?
Yes, with anti-corrosion coatings, CHS is ideal for outdoor construction and infrastructure.

3. Is CHS stronger than flat or angle steel?
CHS offers better torsional and uniform stress resistance due to its round geometry.

4. Are these CHS tubes compliant with Kenyan standards?
Yes — they meet the National Building Code of Kenya (2024) and KEBS standards.
