Metal grating is an indispensable tool in a variety of industrial and commercial settings. It is an assembled grid with crossbars or crimp bars used to space and holds the bearing bars erect. Grating provides a surface but allows air, light, heat, sound, and water to pass through. It is strong, durable, and virtually maintenance-free.

In its most common applications, it helps keep workers and visitors in a facility safe, providing a stable flooring base and traction when walking at ground level and, especially, at heights. It can also serve as an effective safety barrier, helping to deter accidents that could harm staff, equipment, and the facility itself.

What Are the Benefits of stainless-steel grating support for Offshore Industry?

Metal grating can be deployed as everything from standard floor to walkway coverings. Besides safety and durability, it creates a unified aesthetic for the facility.  Overall, it can make a facility appear more cohesive. In this way, it provides a sense of continuity across all surfaces where the material is used. Prefabricated panels can be used in many circumstances where this type of grating meets the needs of the facility.

Stainless steel is broadly customizable, both in terms of the specific content of the alloy and the ways in which it can be manufactured. While there are recommendations and rules set by the International Organisation for Standardisation, many other elements of steel grating are easily changeable to align with specific design requirements and the layout of a facility. In factories, it provides workers with a safe, skid-proof surface on which to walk and operate machinery.

Last week, we assisted our client to install grating and grating support for the gap between the landing platforms. As the landing platforms are subjected to various loadings, helicopters landing on a floating vessel with changing vessel motion need complete safety measurements. Our team has ensured that we provide safe and quality services to our clients.

What were the bolts originally used for?

The history of bolts can be broken down into two parts. First, the threads date back to around 400 BC. They were made from wood. Most of the bolts are used on items such as a spiral for lifting water and pressing grapes to make wine.

In the 15th century, Johann Gutenberg used screws in the fastenings on his printing presses. The tendency to use screws gained momentum with their use being extended to items such as clocks and armor. According to Graves, Leonardo da Vinci’s notebooks from the late 15th and early 16th centuries include several designs for screw-cutting machines.

In 1841, Joseph Whitworth suggested standardizing the size of the screw threads in Britain so that all the nuts and bolts can fit globally. His proposal was that the angle of the thread flanks to be standardized at 55 degrees. At the same time, the number of threads per inch should be defined for various diameters.

Why is Bolt Tension Important to Offshore Industry?

Using a bolt tightening sequence is to reduce the loss of pre-load in the bolt. If the pre-load is lost, the bolt will relax. This could potentially lead to detrimental failure. The loss of preload can result from differences in thermal expansions between the bolt and the joint, along with other mechanisms.

Tension is a controlled way of tightening the bolt on applications within critical industries such as oil and gas, wind energy, construction and nuclear, etc. During bolt tensioning, the bolt is preloaded and stretched during the process. Once this has been completed correctly, with the nut tightened and the tensioner load removed, the bolt will automatically want to return to its original length. It is this spring-like action that creates tension and results in a clamping force across the bolted application.

Our team offered our bolt tightening services to our offshore client last week. By tensioning the bolts, we ensure that they enhance safety and ensure leak-free joints. Controlled bolting with tensioners reduces shutdown intervals. In this way, it improves the efficiency and productivity of the offshore asset.
