What is Steel /Metal Roof Trusses?
Steel roof trusses can be composed of a variety of materials including steel, steel with aluminum, steel with galvanized coating, or stainless steel. They are typically composed of high-density steel or aluminum.
These trusses have been used extensively in construction for many years. They are seen most often in industrial or manufacturing environments but are also seen in residential construction.
Steel roof trusses are typically less expensive than other trusses, but come with greater maintenance requirements.
One of the requirements for steel roof trusses is to provide additional protection from fire. In order to do this, the roofing decking is made of plywood.
Steel roofs are typically made out of metal. Steel roof trusses are typically used in industrial buildings, factories, warehouses, and apartment buildings.
If the building is being constructed in an industrial environment, steel roof trusses may be the only option due to the fire-safety needs.
Types of Steel Roof Trusses
There are several types of steel trusses. They include;
1. Aluminum Metal Roof Trusses
Aluminum roofing is commonly used in residential and commercial roof construction. It has become a popular alternative to traditional steel trusses, as they are of a lighter weight and less costly to install.
Aluminum metal roof trusses are very versatile since they can be installed on almost any type of building, even those that require the use of large machines or heavy lifting equipment.
2. Steel flat roof trusses
Steel flat roof trusses are a simple yet effective roofing solution for low sloped roofs and skylights.
The trusses are constructed of formed steel that is used to support a variety of roofing materials, including sheet metal, plastic, ceramic tile and other factory-made materials.
3. Steel trusses for slanted roofs
Steel slanted roof trusses are made up of interconnected beams that span from vertical walls to a high wall or ridge beam in the back of the structure.
The trusses are used to support the roof of a building and provide a space for electrical wiring, mechanical piping and other necessary components.
They must be installed over a framework that will help to hold them in place while also supporting the weight of the roof and all of its materials.
4. Prefabricated Steel Trusses
Prefabricated steel trusses are made of either welded or bolted components that are assembled into a structure to be used on a building, usually at the end of construction.
The trusses are durable, weatherproof and can be recycled after they have been removed from the building.
5. Galvanized steel roof trusses.
Galvanized steel roof trusses are commonly handcrafted in the same manner as traditional steel roof trusses. They have a rust-resistant finish and are versatile when it comes to being used on building materials.
Galvanized steel roof trusses have a zinc coating that is designed to be anti-corrosive, ensuring they can last for years without becoming damaged by exposure to weathering or rust.
Benefits of Steel Roof Truss
A steel roof truss is a unique truss constructed from steel and a material designed for insulation.
These trusses can be readily fabricated in all shapes and sizes, such as the less common three-sided truss.
In some cases, a steel roof truss is a more cost-effective option than wood. Steel roof trusses are a versatile and cost-effective option.
They are often easier and faster to install than traditional wood trusses, and the material resists fire and decay much better than wood. Steel Roof Trusses are a versatile and cost-effective option.
They are often easier and faster to install than traditional wood trusses, and the material resists fire and decay much better than wood/timber.
Another benefit with this type of system is that it is very cost effective. One of the biggest benefits is that you can get a steel roof truss system that is both strong and lightweight.
Steel Roof Trusses vs. Timber/Wood Roof Trusses
Steel trusses are more durable than wood trusses.
The steel sections that make up the truss are low in weight and can be produced in any configuration that meets the architectural requirements.
There is no risk of white ants or other insects consuming the substance.
Steel trusses have no span constraints; therefore, they can be utilized for industrial buildings and other structures where enormous areas must be covered without impediments such as columns.
The pieces that make up a steel truss are lightweight and easy to transport.
The parts can be obtained in any required shape or length to meet the needs, and there is little material waste due to cutting and other processes.
Roofing work with steel trusses moves quickly due to their simple erection techniques.
Advantages and Disadvantages of Steel Roof Trusses
Advantages of Steel Roof Trusses
The advantages of using a steel roof truss include:
- It is not as expensive as most other types. It is less expensive than other types of roofing because it has fewer of the components needed for a roof that are not required with wood or metal roofs.
- It can be more fire resistant than wood roofs. They are able to hold up to extreme heat.
- They can be more watertight than regular roofs because they do not allow for the same amount of moisture to pass through as a wood roof.
- They are less likely to rot or buckle with age than wood roofs, and they require fewer repairs.
- They are easier to install because they are lightweights, and typically require less but specialized labor to install.
- They are lower maintenance than wood roofs because chemical treatments are not necessary to maintain the trusses.
- The steel roof trusses can be used in more humid climates because they do not allow the same amount of moisture into a building as a wooden roof does.
- Even though they are considered to be more expensive, metal roof trusses can span further than timber.
- Metal roof trusses can be manufactured to exact standards and are well-made.
- Because they are flexible, they can be placed on different levels in the building and will not require structural engineering to be made safe, making them easier to install.
- They can be made with lighter materials such as aluminum or stainless steel than wood trusses can be made of. As a result, they are able to keep a building cooler in the summertime and warm during the winter months.
- Metal roof trusses are compatible with almost all types of roofing systems.
- The metal roof trusses can be seen as a good option for someone who does not want their building to look like an industrial or corporate building. Instead, they can make the building blend in more with surrounding residential areas.
- The metal roof trusses are usually made out of high-strength material, making them able to bear heavy loads in an area where it would be difficult for wooden or steel roofs to do so.
- Steel/Metal roof trusses are recyclable and therefore environmentally friendly.
- It is consistent. Steel trusses are completely It is uniform unlike lumber, which cannot be consistent due to its intrinsic, natural growth environment. They are mass-produced in factories with strict quality control. As a result, the trusses that arrive at the project site are built exactly as specified, with just minor variations – if any. This is not practicable in the case of wood timbers, whose characteristics might change over time, particularly in reaction to temperature and relative humidity fluctuations.
Disadvantages of Steel Roof Trusses
The disadvantages of using steel roof trusses include:
- Skilled labor is required to install steel roof trusses when compared with other types of roofs.
- Metal roof trusses are more expensive than other roof types.
- steel/Metal roof trusses are not energy efficient since they allow more heat to escape from the structure.
- Metal roof trusses allow sound to be more easily transmitted between rooms than other types of roofing.
- Temperature fluctuations allow them to move more than other roof types, and this can cause squeaking in the building.
- The temperature fluctuations and weather conditions can affect the durability of metal roof trusses more than other types.
- They are susceptible to rusting and corrosion more than other types of roof trusses are. They rust faster and corrode more quickly in marine environments or highly acidic environments than wood roofs do. When the metal is cut, drilled, scratched or welded, rust can become a problem.
- There is higher risk of electrocution when installing the metal roof trusses because they can become conductive. Wires that are on the trusses can rub over time creating a hazard to anyone who happens to touch the metal truss..
- They are more prone to damage from wind than other types of roof trusses because the roof is lighter and looser than with wood roofs.
- Despite the fact that they are more fire resistant than wood roof trusses, they still require proper fire safety precautions to be put into place in an industrial or manufacturing environment for safety reasons.
