LIGHT STEEL SIZE

 The size or C profile that is often used on the roof frame is 75 mm x 35 mm, 85 mm x 45 mm, and 55 mm x 25 mm. As for battens, the profiles used are usually 35 mm x 45 mm and 45 mm x 55 mm. Thickness profiles that are usually used are 0.6 mm, 0.7 mm, 0.8 mm and 1 mm.

 In terms of quality standards or SNI standards, mild steel has at least a minimum yield strength of 550 mpa and a maximum tension of 550 mpa. Along with advances in technology used, now the quality of mild steel is also getting better. There are more and more manufacturers of lightweight steel roof trusses that comply with SNI (Indonesian National Standard) standards

 The specifications of each mild steel manufacturer also vary. Usually the information and specifications they will mark or label their products with or you can also get detailed information about their products through the information media provided by them. That way you can find out and determine which product suits your needs.

EXCESS OF LIGHT STEEL

1. Lightweight and Easy to Install

The weight of this lightweight steel roof is quite light when compared to other roofing materials, which is only around 9 kg / m2. This lightweight nature also makes it easier for construction workers to install the roof truss.

2. Strong and Durable

Even though this material is light in weight, the advantage of mild steel itself is its use which is quite strong and durable. In fact, these building materials will not rust and withstand extreme weather, so they can protect your home to the maximum.

3. Easy to Form and Connect

A lightweight steel roof can be the solution to make a building roof according to your wishes. This is because this lightweight steel material can be easily cut and shaped to follow the shape of the roof truss we want. In addition, mild steel can also be connected to other types of roofs using steel connecting materials.

4. High Tensile Tensile

Lightweight steel roofs have more flexible characteristics when compared to other types of roofs. The flexibility of the roof frame is of course very important because the greater the tensile stress of the roof, the more energy that can be absorbed.

LESS STEEL LESS

You already know what mild steel is and the advantages of using it. The following are the shortcomings of mild steel materials:

1. Prices are not cheap

Because of the quality and all the advantages that can be obtained, it turns out that the price of a lightweight steel roof is quite expensive. However, its use also depends on the brand you use for the roof construction.

2. Easy to be carried away by the wind

Due to its light nature, mild steel itself can easily be carried away by the wind. However, if you put it right, it won't happen. The bolt-only lightweight steel connection system allows strong winds to blow the roof frame off the house being built.

3. Disorder appears

The roof structure of the house actually has to be able to accommodate the heavy roof loads. This is an added value for the strength of the foundation of the house, but from an aesthetic point of view, the density of this lightweight steel frame seems messy and can damage the beauty of the building.

4. Vulnerable to collapse if not thorough

Lightweight steel roofs use a net-shaped system to build a strong and durable roof. This will be dangerous if not calculated properly. Failure to calculate the roof construction of a house can result in such a complete failure that the roof may collapse.
