Today, steel is used on the roofs of almost all modern buildings, whether they are homes, shophouses or office buildings. Due to many factors, steel frames have become very popular today. One of its advantages is its strength. The steel frame of the roof is very strong and supports heavy loads.
In addition, steel frames have a longer lifespan than wooden structures that are easily eaten by termites. Steel frames are also fairly easy to install. It's pretty easy, but you can't underestimate the steel installation. Before installing the steel frame, please note the following 6 points!
Light steel roof truss type
The choice of mild steel is very important and this is the main thing to consider. Please select the type of steel frame according to the function.Above all, light steel type span deck roof, selection of steel frame to choose from roof Polycarbonate solar light Or the roof Polycarbonate xlite, And roof It will be green.
Steel frame integrated type
Speaking of steel frames, the units used are a system with a sense of unity. The key to its strength lies in the integration of each steel bar connected to the joint as a whole. A small error in one frame affects the entire roof. Some are not fully applied and the entire building can collapse with fatal consequences.
Lightweight steel roof truss slope
When installing steel, you need to know the slope of the roof. Of course, the steeper the slope, the wider the roof.Ideally, the slope of the roof is between 250 Or 300.. With such a sloping roof, the building looks ideal and fits better.
Consider the weight of the steel frame
Not only should you pay attention to the type of steel used, but also the load on the steel. This has a significant effect on the durability and strength of the steel frame. It cannot be calculated with certainty, but it can be calculated using an estimate by paying attention to the roofs used and the number of roofs used.
Anti-corrosive coating on steel frame
One of the key components of mild steel is the coating coating Rust prevention. Of course, the types of coatings used by each mild steel brand are different. Some are in the form of zinc plating (zinc), galvalume roofs, zinc aluminum (a combination of zinc, aluminum and silicon) and ZAM (zinc, aluminum, magnesium). The difference in this mixture affects resistance to other substances such as salts, acidic solutions and alkaline solutions.
Each type also has its own thickness. Generally, the thickness used is 100-150 gr / m.2 Or, it is often written in AZ100 code (adjusts the thickness level). However, for mild steel sold separately, the AZ value is usually 100 or less. The thinner the coating, the more easily the rust-preventive coating is scratched and the more easily the mild steel corrodes.
Installation of steel frames by experts
A common mistake is that the steel is not installed by a specialist. Therefore, the installation method is not really understood. Note that the steel installation is a unified system, although it is made up of several elements. No part of it can stand on its own. Therefore, it is advisable to create a working drawing before installation.
These are six things to consider before deciding to install a steel frame. Given the role of steel roof trusses in building construction, deep knowledge is required before installing mild steel.
