Every strong roof begins with a solid framework. In roofing, that structure is your truss system. Whether you are constructing a home, warehouse, church, or commercial building, the trusses you choose will determine the strength and durability of your roof.

At Troysteel Company Limited, we do more than supply roofing sheets. We build and deliver full roof support systems carefully designed to meet the demands of Ghana’s weather and building requirements. From trusses and purlins to ceiling noggins and structural accessories, our focus is on quality, strength, and long-term value.

This guide explains everything you need to know about trusses in Ghana, including the types, gauges, materials, coatings, and the benefits of working with Troysteel Roofing.

What Are Roof Trusses and Why Do They Matter

Roof trusses are the framework that supports your roofing sheets. They transfer the load of the entire roof structure down to the walls of your building. If your trusses are weak, the roof may sag, shift, or fail entirely. That is why it is essential to choose high quality materials and precise fabrication.

At Troysteel, we manufacture several types of trusses to suit different structures:

King Post Truss – Simple and reliable, often used in single storey buildings and residential projects
Howe Truss – Designed for larger roofs, often used in schools, churches, and event halls
Pratt Truss – Balanced for strength and weight, suitable for medium to large buildings
Scissor Truss – Allows for vaulted ceilings and interior design flexibility

Each truss is engineered according to your specific building design and roof span.

Why We Use Aluzinc Steel for Trusses

At Troysteel, we use Aluzinc steel for all truss components. Aluzinc is a superior alternative to traditional galvanized steel and is especially effective in Ghana’s humid and coastal environments.

Aluzinc is made from the following combination:

Aluminium, which offers strong resistance to rust
Zinc, which forms a protective barrier on the surface
Silicon, which strengthens the bond between the coating and the steel

The result is a metal that lasts longer, stays clean, and holds up better in extreme weather.

Available Gauges and Their Applications

The thickness of the steel, also called the gauge, directly impacts how much weight a truss system can carry. At Troysteel, we cut and roll all gauges to meet the needs of each individual project.

All components are manufactured using accurate measurements and clean finishes to ensure proper installation on site.

Component	Gauge Range (mm)	Purpose
Main Trusses	1.5 mm to 2.5 mm	Main load support
Internal Bracing	1.2 mm to 1.8 mm	Strengthens the frame
Purlins	1.2 mm to 2.0 mm	Supports roofing sheets
Ceiling Noggins	0.9 mm to 1.2 mm	Holds the ceiling panels in place

Purlins and Ceiling Noggins Explained

Purlins and ceiling noggins are key parts of the truss system, even if they are not always visible.

Purlins are metal beams placed across trusses to support the roofing sheets. They prevent sheets from sagging and distribute weight evenly.
Ceiling noggins are smaller steel sections placed beneath the trusses. They form the framework that holds ceiling panels in place, making sure the ceiling is level and strong.

We fabricate both components from Aluzinc and deliver them along with your trusses for a complete package.

Zinc Coating and Protection Against Rust

All our steel is coated with a protective layer of zinc to ensure long term performance. We use coating grades between G275 and G300, which means there are 275 grams to 300 grams of zinc per square metre.

This coating:

Protects steel from rust and corrosion
Increases the lifespan of your trusses
Reduces the need for maintenance or repainting
Performs well in coastal, humid, and rainy areas of Ghana
