These Are Some Of The Failure Factors Of Light Steel Structures

There are several factors that can make light steel structures fail. In this article, we will share information about these factors with you. Apart from that, you may call the Special Inspections Santa Ana CA if you need professional inspectors to inspect your steel structure.

Following are the failure factors of light steel structures:

Currently, mild steel has become a mass product, easily found everywhere and can be bought and installed by anyone, including by incompetent parties to become contractors or structural installers.

If you want to be safe, yes, light steel structures must be calculated with the right software. However, the price is quite expensive, it can be a lot of money. Another alternative is to rent the software. The rental price is can be quite expensive per year. Judging from this value alone, it has been seen that the software usage requirements will not be able to be fulfilled by small contractors.

The sheet metal base material is currently widely circulating, whose quality is not intended for light steel roof truss structures. For example, the material strength requirements that should be G550 High tensile steel, it turns out that when tested below that, it is said that there are even only G370 mild steels. Not that the G370 is bad. But for roof truss, the minimum requirement is G550.

Anti-rust coating or non-standard coating. For Galvanized (Zinc), minimum Z180 (thickness of 180 grams / m2), for minimum AZ150 Galvalume (aluminum-zinc) (150 gram / m2). Try to check, on the market circulating AZ100 is even less.

The number of screws (having rough grooved self-drilling screws) and screw quality are often ignored. At each connection point, a minimum of 3 screws must be installed. In fact, sometimes only 1-2 screws like to miss the hole. The standard US 3556 high strength screw was replaced by a cheaper, ordinary screw, and some even used finely grooved screws which were not intended for roof frames.

The loading conditions are often ignored. Not only the roof cover load, wind and rain loads should also be calculated and different (typical) in each region.
